ABSTRACT<br />
Rich assemblages of smaller <strong>Foraminifera</strong> are tabulated from<br />
two samples representing the upper Eocene, four samples repre<br />
senting the lower Oligocene, and seven samples representing the<br />
Miocene; some of the species are illustrated. A late Eocene<br />
(Tertiary &) age for part of the Alutom Formation is supported<br />
by the planktonic species of the f oraminif eral population. Abun<br />
dant planktonic <strong>Foraminifera</strong> in the Mahlac Member of the<br />
Alutom Formation permit correlation of the Mahlac Member<br />
with the GloMgerina sellii zone of early Oligocene age, which<br />
was described from East Africa.<br />
The hiatus between Oligocene and Miocene is marked by a<br />
major faunal change in which more than 40 percent of the<br />
Oligocene assemblage became extinct. The Miocene assemblage<br />
from the Janum Formation is similar in species and in paleo-<br />
ecology to modern sediments around <strong>Guam</strong>. Although larger<br />
<strong>Foraminifera</strong> indicate a probable age of Tertiary g for part of the<br />
Janum Formation, the evidence of the planktonic <strong>Foraminifera</strong><br />
favors an age of Tertiary /.<br />
Because the correlation of the planktonic <strong>Foraminifera</strong> zona-<br />
tion with the Oligocene-Miocene boundary and with the Euro<br />
pean time scale has been altered during the past decade, it is<br />
necessary to correct two of the age assignments originally made.<br />
The Donni Sandstone Member of the Tagpochau Limestone of<br />
Saipan is now considered as approximately Tortonian (Ter<br />
tiary /) and the Globifferinatella insweta/Globigerinoicles M-<br />
spherica zone on Saipan and Yap is considered as early Miocene<br />
(Aquitanian and Tertiary e). Correlation of the Janum Forma<br />
tion is based chiefly on GloMgerina nepenthes, and the age of<br />
the Janum is estimated to be slightly younger than that of the<br />
Donni, but still approximately Tortonian in part.<br />
Study of species from beaches, reefs, lagoons, channels, and<br />
outer slopes around <strong>Guam</strong> provides a basis for paleoecologic<br />
interpretation of moderately deep outer-slope deposition in the<br />
three formations studied.<br />
INTRODUCTION<br />
This paper records the assemblages and illustrates<br />
some of the species of smaller <strong>Foraminifera</strong> character<br />
istic of three different ages of sedimentary rocks on<br />
<strong>Guam</strong>: late Eocene (Tertiary 6) in the Alutom Forma<br />
tion, early Oligocene (Tertiary c) in the Mahlac Mem<br />
ber of the Alutom Formation, and Miocene (Tertiary<br />
f or g) in the Janum Formation. The <strong>Foraminifera</strong><br />
found in the beach sands, on the reefs, in the lagoons<br />
and channels, and on the outer slopes around <strong>Guam</strong>,<br />
are also recorded.<br />
GEOLOGY AND HYDROLOGY OF GUAM, MARIANA ISLANDS<br />
SMALLER FORAMINIFERA FROM GUAM<br />
By RUTH TODD<br />
The several assemblages here discussed are compared<br />
with those of comparable ages and ecology that have<br />
already been described from the nearby island of Sai<br />
pan, about 120 miles north-northeast of <strong>Guam</strong> (Todd,<br />
1957). Comparisons are also made with Recent and fos<br />
sil assemblages described from several islands of the<br />
Marshall Island group, particularly Eniwetok and<br />
Bikini, respectively some 1,150 to 1,350 miles east of<br />
<strong>Guam</strong> (Cushman and others, 1954; Todd and Post,<br />
1954; Todd and Low, 1960).<br />
I am grateful for helpful advice, discussions, and<br />
suggestions received from many colleagues during the<br />
course of my work. Doris Low worked with me and<br />
gave invaluable assistance in the preparation of the<br />
material for study and the tabulation of results. The<br />
drawings are the work of Elinor Stromberg.<br />
ANALYSES OF FAUNAS<br />
EOCENE, TERTIARY b<br />
The Eocene is represented by only two samples: Ei 4-1<br />
and Jl 2-1. In both these samples from the Alutom<br />
Formation of late Eocene and Oligocene age, planktonic<br />
specimens are noticeably predominant, and the ben-<br />
thonic specimens, although comprising a larger number<br />
of species, are few. Because of this predominance of<br />
the planktonic element, both samples are interpreted as<br />
relatively deep water deposits, such as are currently<br />
being deposited on the outer slopes of <strong>Guam</strong>.<br />
The interpretation of the age of the foraminiferal<br />
assemblage is based upon several considerations. First,<br />
the two most abundant planktonic species, Globorotalia,<br />
centralis Cushman and Bermudez and Globigerapsis<br />
index (Finlay), indicate middle or upper Eocene (Bolli,<br />
195Tc, text fig. 26 [range chart]).<br />
Second, both samples contain rare specimens of the<br />
Eocene genus Hantkenina. Sample Ei 4-1 contains<br />
Hantkenina alabamensis Cushman, and in sample Jl 2-1,<br />
both H. alabamensis and H. inflata Howe are present.<br />
Both of these species are reported in the upper Eocene,<br />
and H, alabamensis is reported to range also into the<br />
middle Eocene, at least sporadically (Thalmann, 1942,<br />
table 1).<br />

12 GEOLOGY AND HYDROLOGY OF GUAM, MARIANA ISLANDS<br />
Third, several other planktonic forms from these<br />
two samples, all rare, also have restricted ranges, as<br />
follows: GloborotaHa spinulosa Cushman and G. spinu-<br />
loinflata (Bandy) are both reported (Bolli, 1957c, text<br />
fig. 26 [range chart]) to be confined to the middle<br />
Eocene. Globorotalia wilcvxensis Cushman and Ponton<br />
is reported (Bolli, 1957a, text fig. 11 [range chart]) to<br />
be restricted to the lowermost Eocene. Still other plank-<br />
tonic species, also rare, are less narrowly restricted but<br />
do include the Eocene within their ranges. They are<br />
Globigerina pera Todd and G. yeguaensis Weinzierl and<br />
Applin, which range from middle Eocene to but not into<br />
the Chattian, Globigerina gortanii (Borsetti), which<br />
ranges from upper Eocene to but not into the Chattian<br />
(Eames and others, 1962, text fig. 20 [range chart]),<br />
and Globigerina venezuelana Hedberg, which ranges<br />
from middle Eocene upward throughout the Oligocene<br />
and Miocene (Bolli, 1957b; 1957c, text figs. 18,26 [range<br />
charts]).<br />
In spite of the apparent restriction of a few of the<br />
rarer Eocene planktonic species to middle and lower<br />
Eocene, I believe the age of these two samples from<br />
the Alutom Formation can be best interpreted as late<br />
Eocene.<br />
Among the benthonic species, only a few appear to<br />
have restricted stratigraphic ranges. Of these, the fol<br />
lowing support the late Eocene age that is indicated by<br />
the planktonic specimens. An asterisk indicates species<br />
that seem to have become locally extinct after the<br />
Eocene.<br />

The remaining benthonic species are either wider<br />
ranging or are too poorly preserved to be identified<br />
with certainty. A few, such as Oridorsalis umbonatus<br />
(Reuss) and Osangularla cutter (Parker and Jones),<br />
appear to have ranges extending from Eocene to Eecent.<br />

Tertiary c beds are represented by four samples from<br />
the Mahlac Member of the Alutom Formation. The<br />
assemblages in two of these samples, Hi 6-1 and Gj<br />
13-1, are very rich and well preserved.<br />
A few species are identical with those in the Eocene<br />
fauna, but the Oligocene assemblages are much richer<br />
than those of the Eocene and include more than 2i/£<br />
times as many species. Like the Eocene samples, these<br />
Oligocene ones are predominantly composed of plank-<br />
tonic specimens. Therefore, I intrepret them as from<br />
the outer slope, probably from moderately deep deposits.<br />
Again, as in the Eocene samples, the interpretation<br />
of age is based primarily on the planktonic assemblages.<br />
The planktonic assemblage is more varied than that<br />
in the Eocene samples. The most narrowly restricted<br />
forms are Globigerina sellii (Borsetti) and Globigerina<br />
tripartita Koch tapuriensis Blow and Banner, whose<br />
ranges are indicated (Eames and others, 1962, text<br />
fig. 20 [range chart]) to be restricted to Lattorfian and<br />
Rupelian.<br />
Globigerina ampliapertura Bolli, G. gortanii (Bor<br />
setti), G. increbescens Bandy, G. senilis Bandy, G.<br />
yeguaensis Weinzierl and Applin, and Cassigerinella<br />
chipolensis (Cushman and Ponton) all include the<br />
Lattorfian-Rupelian in their ranges. Globigerina am<br />
X<br />
X<br />
X<br />
X<br />
pliapertura ranges slightly higher and slightly lower;<br />
G. gortanii, G. increbescens, and G. senilis range lower<br />
but no higher; G. yeguaensis ranges much lower but no<br />
higher; and Cassigerinella chipolensis ranges much<br />
higher but no lower (Eames and others, 1962, text fig.<br />
20 [range chart]). Globigerina dissimilis Cushman<br />
and Bermudez, G. suteri (Bolli), and G. venezuelana.<br />
Hedberg are all reported (Bolli, 1957b; 1957c, text figs.<br />
18, 26 [range charts]) as having long ranges, extending<br />
from Eocene to Miocene. Globigerina opima nana<br />
(Bolli) is reported as ranging no higher than Oligocene<br />
in Trinidad (Bolli, 1957b, text fig. 18 [range chart])<br />
but as having a long range, from Eocene to Miocene,<br />
in East Africa (Eames and others, 1962, text fig. 20<br />
[range chart]). In either interpretation, its range does<br />
include the Lattorfian-Rupelian. Globigerina danvil-<br />
lensis Howe and Wallace and Globigerinella danvillen-<br />
sis (Howe and Wallace) (originally described under<br />
N onion] were both first described from the Jackson<br />
Eocene at Danville Landing, La. Both have been re<br />
ported from other areas, mostly in the Eocene but also<br />
in the lower Oligocene. Chiloguembelina cubensis<br />
(Palmer), described from the upper Eocene and lower<br />
Oligocene of Cuba, is reported (Beckmann, 1957, text<br />
fig. 16) to extend the upper part of its range into the<br />
Globigerina ampliapertura and Globorotalia opima<br />
opima zones of the Oligocene in Trinidad.<br />
In consideration of the ranges reported for the vari<br />
ous planktonic species found in the four Oligocene sam<br />
ples, it may be said with a fair amount of confidence<br />
that the age of the samples falls somewhere in the Lat<br />
torfian or Rupelian and also within the Globigerina<br />
sellii zone (Blow and Banner, 1962, p. 68, text fig. 20<br />
[range chart]).<br />
Probably the closest known assemblage (both in<br />
faunal similarity and geographic distance) to this one<br />
from the Alutom Formation is the one reported from<br />
Lindi in Tanganyika on the east coast of Africa (Blow<br />
and Banner, 1962).<br />
The finding of a single specimen of the Eocene genus<br />
Hantkenina in the Oligocene sample Hi 6-1 throws<br />
doubt on the inclusion of this sample with the other<br />
three of Oligocene age. In spite of diligent search for<br />
additional specimens of Hantkenina to confirm its oc<br />
currence in Hi 6-1, no more specimens were found, and<br />
it was concluded that the single specimen was rede-<br />
posited from older beds. Moreover, evidence of re<br />
working in Hi 6-1 has already been reported by Cole<br />
(1963, p. E4 and table 1) who found Eocene larger<br />
<strong>Foraminifera</strong> in this sample.<br />
The lack of Globigerina sellii (Borsetti), the zone<br />
fossil that is reported to be limited to the zone, throws<br />
further doubt on the precise correlation of sample Hi
14 GEOLOGY AND HYDROLOGY OF GUAM, MARIANA ISLANDS<br />
6-1 with the other three samples, Gj 13-1, Gj 11-1,<br />
and Gj 14-1, that are assigned to this zone. The fur<br />
ther circumstance that sample Hi 6-1 contains three<br />
additional planktonic species, namely Globigerina dan-<br />
vUlensis Howe and Wallace, G. yeguaensis Weinzierl<br />
and Applin, and Globigerinella danvittensi-s (Howe<br />
and Wallace), none of which are found in any of the<br />
other three Oligocene samples and all of which have<br />
ranges extending farther downward than upward from<br />
the lower Oligocene, is yet another point in favor of<br />
differentiating sample Hi 6-1 from the remaining three<br />
Oligocene ones. The recognition in sample Hi 6-1<br />
of forms transitional between Globigerina ampliaper-<br />
tura Bolli and Globorotalia centralis Cushman and<br />
Bermudez forms identical with some illustrated from<br />
the highest Eocene zone in Trinidad is an additional<br />
point in favor of interpreting Hi 6-1 as slightly older<br />
than the Globigerina sellii zone.<br />
Nevertheless, in spite of the fact that the previously<br />
discussed points favor a pre-early Oligocene age for<br />
sample Hi 6-1, there are some weighty reasons for in<br />
cluding it with the Oligocene rather than with the<br />
Eocene, as follows: First, the presence of Cassigerinella<br />
chipolensis (Cushman and Ponton) in abundance favors<br />
Oligocene age because this genus has not been reported<br />
in the Eocene. However, the question of exclusion of<br />
Cassigerinella from the Eocene is currently under debate<br />
owing to Tsunemasa Saito's finding (written commun.,<br />
Jan. 10, 1964) of some small specimens of it in a deep-<br />
sea core in the Atlantic off Florida where it was reported<br />
in association with undoubted Eocene planktonic<br />
<strong>Foraminifera</strong>. Second, the presence of many species<br />
characteristic of the lower Oligocene, such as Bolivina<br />

Table 2 gives the species of smaller <strong>Foraminifera</strong> of<br />
Oligocene age found in the Mahlac Member of the<br />
Alutom Formation on <strong>Guam</strong>. The few species noted<br />
in a preliminary study that was made of these same<br />
samples and incorporated into a report by Tracey and<br />
others (1964, p. A22) included a few names not given<br />
in the following table. These discrepancies have re<br />
sulted from the shifting of a species from one genus<br />
to another (such as Cassidulina chipolensis to Cassi-<br />
gerinella), from the synonymizing of one species with<br />
another (such as Siphogenerina, seriata, a synonym of<br />
8. striata), from the correction of identification (such<br />
as Bolivina aff. B. tricosta for B. choctawensis), and
16 GEOLOGY AND HYDROLOGY OF GUAM, MARIANA ISLANDS<br />
from the refinement of identification (such as Bolivi-<br />

Above the Mahlac Member of the Alutom Forma<br />
tion, a considerable thickness of Miocene beds inter<br />
venes between the Mahlac Member and the next higher<br />
formation in which smaller <strong>Foraminifera</strong> are found.<br />
Therefore, a radical difference in smaller <strong>Foraminifera</strong><br />
is evident between the fauna of the lower Oligocene<br />
and that of the upper Miocene. In many of its aspects<br />
the Miocene is only subtly different from the Recent<br />
now found around <strong>Guam</strong> in a comparable environment.<br />
The Eocene, although much less rich and less varied<br />
than the Oligocene, has a large proportion of its species<br />
(44 percent) in common with the overlying Oligocene.<br />
The Oligocene assemblage, on the other hand, although<br />
composed of nearly 150 species as compared with the<br />
92 species of the Miocene, has only 14 species (less than<br />
10 percent) in common with the Miocene. Moreover,<br />
probably more than 60 species (more than 40 percent<br />
of the Oligocene assemblage) became extinct between<br />
the lower Oligocene and the upper Miocene.<br />
MIOCENE, TERTIARY / OR g<br />
The Miocene Janum Formation, like the upper Eocene<br />
and Oligocene Alutom Formation, was formed in mod<br />
erately deep water. Planktonic specimens are predom<br />
inant and are accompanied by meager representatives<br />
of a varied benthonic assemblage.<br />
A total of seven samples from vertical sections (four<br />
at Catalina Point, two at Lujuna Point, and one at<br />
Anao Point) represent the Miocene Janum Formation.<br />
Only one sample, Rr 15-1, has a rich fauna. Locations<br />
of these three vertical sections as well as of the other<br />
samples studied on <strong>Guam</strong> are shown in figure 1.<br />
As is true for the other fossil assemblages, the in<br />
terpretation of age is based primarily on a few plank-<br />
tonic species; however, several of the many benthonic<br />
species serve to support and confirm the age indicated<br />
by the planktonic species. Because the original de<br />
termination of the Janum Formation was made (Cole,<br />
1963, p. E10; Tracey and others, 1964, p. A43) largely<br />
on the basis of field evidence a Tertiary / species of<br />
Lepidocyclina within a pebble interpreted as having<br />
been reworked and two species characteristic of the<br />
Barrigada Limestone of Tertiary g age that were found<br />
in place at the base of the Janum Formation the as<br />
signment of the Janum Formation to Tertiary g may<br />
be open to question. Correlation of the Janum Forma<br />
tion is discussed under incongruities of correlations<br />
(p. 121-123).<br />
On <strong>Guam</strong> the following planktonic species are charac<br />
teristic of and restricted to Miocene; the species marked<br />
by an asterisk are undoubtedly known in the Recent (see<br />
Todd, 1964) but were not found in the Recent Gflobig-<br />
erhia ooze around <strong>Guam</strong>:<br />

Among the planktonic species, only the ones men<br />
tioned below seem to be useful in limiting the age of the<br />
formation to a specific part of the Miocene.<br />
Globigerina, nepenthes Todd was described from the<br />
Donni Sandstone Member of the Tagpochau Limestone<br />
of Saipan. Its vertical range in Venezuela and Japan<br />
is reported (Blow, 1959, p. 178; Takayanagi and Saito,<br />
1962, text fig. 2) to be limited to the Globorotalia<br />
mayeri/Globigerina nepenthes subzone and the Glo-<br />
l)orotalia menardii menardii/Globigerina nepenthes<br />
zone. These two zones encompass the upper part of the<br />
Vindobonian and the lower part of the Sarmatian.<br />
The occurrence of G. nepenthes in several deep-sea cores<br />
from North Atlantic sediment interpreted as Pliocene<br />
(Ericson and others 1963, text fig. 5) does not require<br />
the upward extension of range of this species, inasmuch<br />
as these authors mention (p. 733) the Miocene aspect of<br />
the Pliocene and state that "the survival of Miocene<br />
species into the Pliocene epoch implies that no abrupt<br />
or drastic temperature change occurred at the Miocene-<br />
Pliocene time boundary." A more reasonable explana<br />
tion of the presence of Miocene species in the Pliocene<br />
might be that the sediments are, in reality, Miocene and<br />
that the Pliocene is less thick in the deep-sea Atlantic<br />
than has been thought.<br />
Globoquadrina altispira (Cushman and Jarvis) was<br />
originally described from the Miocene of Jamaica and<br />
has been widely reported from the Miocene of many<br />
parts of the world in the equatorial belt. Its reported<br />
occurrences indicate that G. altispira may be expected<br />
in any part of the Miocene, although it possibly has<br />
greater or lesser restricted ranges in various areas. On<br />
Saipan it was found (Todd, 1957, table 3) in the Donni<br />
Sandstone Member of the Tagpochau Limestone, where<br />
it occurred in association with Globigerina nepenthes<br />
Todd. It also occurs, but without the association of<br />
Globigerina nepenthes, in the underlying Fina-sisu<br />
Formation (Todd, 1957, table 2), which was originally<br />
described as of late Oligocene age but here is regarded<br />
as of early Miocene age. In the Trinidad zonation it<br />
was reported (Bolli, 1957b, text fig. 18) to range within<br />
most of the Miocene, with the exception of the one low<br />
est zone and the two highest zones. In Trinidad, Glo<br />
boquadrina .altispira and Globigerma nepenthes are<br />
reported to have mutually exclusive ranges; G. ne<br />
penthes occurs in the two uppermost zones of the<br />
Miocene. Likewise in Venezuela, the ranges of Glo<br />
boquadrina, altispira and Globigerina nepenthes are<br />
mutually exclusive. Globigerina nepenthes first ap<br />
pears at a higher horizon than the highest known occur<br />
SMALLER FORAMINIFERA FROM GUAM 19<br />
rence of Globoquadrina altispira (Blow, 1959, p. 179,<br />
183).<br />
In some short deep-sea cores from a guyot adjoining<br />
Eniwetok Atoll (Todd, 1964), Globoquadrina altispira<br />
occurs in the sections of the cores interpreted as late<br />
Miocene. Other recorded occurrences of G. altispira<br />
from the Miocene in the Pacific are from the Mid-Pacific<br />
Mountains (Hamilton, 1953), Sylvania Guyot off Bikini<br />
(Hamilton and Rex, 1959), and Yap Island in the<br />
Carolines (Cole and others, 1960).<br />
Several estimates of the age ranges of these two spe<br />
cies have been made. Blow (1959, chart 1) assigns the<br />
zones in which he reports Globoquadrina altispira to the<br />
Aquitanian and Burdigalian, and he assigns the zones<br />
in which he reports Globigerina nepenthes to the Vindo<br />
bonian and Sarmatian. Stainforth (1960, range chart<br />
and p. 222) reports the range of Globoquadrina altispira<br />
to be from Stampian and Chattian to the Helvetian.<br />
Drooger (1956, text fig. 1) reports the range of Globo<br />
quadrina altispira to be from Aquitanian to Tortonian.<br />
The genus Sphaeroidinella is well represented in the<br />
Janum Formation. The specimens belonging in this<br />
genus fall into four species that are connected, by transi<br />
tional individuals, into a single complex. This Sphae-<br />
roidinell'a complex includes, at one extreme of morpho<br />
logical development, specimens having five or more<br />
chambers in the final whorl and a distinctly lobulated<br />
periphery S. kochi (Caudri). At the opposite ex<br />
treme are specimens of S. dehiscens (Parker and Jones),<br />
the common Recent species that is nearly globular and<br />
unindented and that is composed of three chambers in<br />
the final whorl. The forms intermediate between<br />
these two extremes are identified as S. seminulina.<br />
(Schwager). They show three or four chambers in the<br />
final whorl and' have a slightly indented periphery.<br />
The fourth member of the Sphaeroidinella complex is<br />
S. disjuncta Finlay, which is distinguished by its<br />
coarsely reticulated wall surface. In number of cham<br />
bers per final whorl and in the lobulation of its periph<br />
ery, S. disjuncta includes both specimens that would be<br />
called S. kochi and others that would be called 8.<br />
seminulina.<br />
Three of the previously discussed species of Sphae<br />
roidinella,, that is, all but /S. dehiscens, are Miocene<br />
species. Moreover, /S. dehiscens, although characteris<br />
tic of, and abundant in, many Recent deep water samples,<br />
has also been found in the Miocene (Todd, 1957, pi. 79,<br />
fig. 8). Thus the Sphaeroidinella complex supports a<br />
Miocene age for part of the Janum Formation.<br />
Another highly variable complex in the Miocene may<br />
be called the Globorotalia menardii-tumida transition<br />
form. It includes rare individuals that, by themselves,<br />
could be regarded as typical of G. menardii (d'Orbigny)
110 GEOLOGY AND HYDROLOGY OF GUAM, MARIANA ISLANDS<br />
and of G. tumida (Brady) ; however, most of the spec<br />
imens fall somewhere between the two. The transition<br />
form has a rather broad and thick test that has heavy<br />
walls, a limbate keel, a slightly curved dorsal surface,<br />
and chambers slightly inflated ventrally. With these<br />
specimens are others nearly typical of the subspecies<br />
fijiensis, which is characterized by a slightly flatter and<br />
rounder test, more numerous chambers, and a tendency<br />
toward peripheral lobulation; the subspecies ungulata,<br />
which is characterized by a more nearly planoconvex<br />
test, a more inflated ventral surface, and an angled<br />
ventral face of the final chamber; and the subspecies<br />
flexuosa, which is characterized by a final chamber that<br />
is reduced in size and is bent under nearly 90° toward<br />
the ventral side.<br />
In addition there appears to be a close and probably<br />
transitional relationship with specimens placed in<br />
Globorotalia fohsi robusta Bolli. Biologically, the two<br />
species Globorotalia menard'd (d'Orbigny) and Globo<br />
rotalia fohsi robusta Bolli may have no connection, but<br />
morphologically, they seem closely related. G. fohsi<br />
robusta has the heavy limbate keel that is characteristic<br />
of the G. menardii-tumida complex. However, G. fohsi<br />
robusta is a flatter, more compact form having one or<br />
two more chambers per final whorl, and its aperture<br />
is a low slit rather than an arch, as in the G, menardii-<br />
tumida transition form.<br />
Globorotalia fohsi robusta Bolli, which is a zone<br />
marker in the upper part of the Burdigalian and just<br />
beneath the lowest part of the range of Globigerina<br />
nepenthes Todd, is represented by only a few specimens<br />
and is found only in sample Kr 15-1. Its occurrence<br />
together with G. nepenthes may serve to define the age<br />
of the Janum Formation as near the upper limit of<br />
the range of the older species Globorotalia fohsi<br />
robusta Bolli and near the lower limit of the range<br />
of the younger one Globigerina nepenthes Todd.<br />
It is of interest that some 20 years ago, well before<br />
the recognition of the value of planktonic species as age<br />
indicators, Glaessner (1943, p. 68-69) published a "ten<br />
tative list of selected species of smaller <strong>Foraminifera</strong>,"<br />
under the heading "Miocene index <strong>Foraminifera</strong>." In<br />
the list of 44 species, all but 2 species of Sphaeroidinella<br />
are benthonic forms. Six species in Glaessner's list of<br />
44, namely the 2 species of 8phaeroidinella, Nodosaria<br />
skobina Schwager, Nodosaria equisetiformis Schwager,<br />
Pyrulina labiata (Schwager), and Osangularia suiter<br />
(Parker and Jones) ( = Pulvinulinella bengalensis in<br />
Glaessner's list), are identical with the species identified<br />
from the Miocene of the Janum Formation of <strong>Guam</strong>.<br />
In addition, there is a high degree of generic simi<br />
larity between Glaessner's list of "Miocene index Fora<br />
minifera" and the Miocene species from <strong>Guam</strong>. Dis<br />
regarding the 6 species in Glaessner's list that are found<br />
in the Miocene of <strong>Guam</strong>, the 38 remaining species fall<br />
into 25 genera. Twelve of these genera are represented<br />
in the Miocene of <strong>Guam</strong>, and it is possible that some of<br />
the species will prove to be not only generically identi<br />
cal but specifically so. For example, Vulvulina nico-<br />
barensis (Schwager) is possibly identical with V.<br />
spinosa Cushman; Eggerellal subovalis (Schwager) is<br />
possibly identical with Eggerella brad.yi (or with<br />
Karreriella bradyil} ; Karreriella siphonella (Reuss) is<br />
possibly identical with K. l>radyi (Cushman) ; and<br />
Uvigerina hispida Schwager is possibly identical with<br />
Uvigerina prob

The chief local differences between the Miocene and<br />
the Recent benthonic faunas are in the families Textu-<br />
lariidae (7 species in the Recent and 1 in the Miocene),<br />
Miliolidae (52 in the Recent and 2 in the Miocene),<br />
Spirillinidae and Discorbidae (15 in the Recent and<br />
not represented in the Miocene), and the families<br />
Rotaliidae, Pegidiidae, Amphisteginidae, Calcarinidae,<br />
and Cymbaloporidae (27 in the Recent and only 3<br />
rotaliids in the Miocene). Thus there is not much in<br />
common between the Miocene benthonic and the Recent<br />
benthonic faunas. If anything, I believe the kinds of<br />
benthonic species present in the Miocene, supported by<br />
the negative evidence of the kinds that are not present<br />
in the Miocene, indicate that the beds represented by<br />
the few Miocene samples studied were deposited at<br />
greater depths and farther from shore than the Recent<br />
outer slope samples that were taken from depths less<br />
than 200 fathoms.<br />
Table 3 gives by localities the smaller <strong>Foraminifera</strong><br />
of Miocene age found in the Janum Formation on<br />
<strong>Guam</strong>. Discrepancies are to be found between the<br />
species noted in my original examination of these same<br />
samples (Tracey and others, 1964, p. A43) and the<br />
species given in table 3. These discrepancies have re<br />
sulted from (a) the shifting of a species from one genus<br />
to another (such as Eponides umbonatus to Oridorsalis<br />
and Siphonodosaria fijiensis to Orthomorphina) ; (b)<br />
the synonymizing of one species with another (such as<br />
Globigerina veneziwlana, a synonym of G. conglom-<br />
erata, and Osangularia bengalensis, a synonym of 0.<br />
culter) ; (c) the correction of identification (such as<br />
Pulleniatina obliquiloculata for Globigerina inflata and<br />
Globorotalia hirsuta for G. canariensis) ; and (d) the<br />
refinement of identification (such as Gyroidina lamar-<br />
ckiana and G. soldanii for G. spp.). In addition, some<br />
of the indeterminate species and those whose generic<br />
placement was questioned in the original study have<br />
been eliminated from table 3.<br />

<strong>Foraminifera</strong> were studied from 98 Recent samples.<br />
The samples have been grouped into the following<br />
categories :<br />
Beaches:<br />
(15 samples).<br />
Reefs:<br />
Agana Reef (10 samples).<br />
Achang Reef (8 samples).<br />
Pago Reef (12 samples).<br />
Cocos Barrier Reef (3 samples).<br />
Cocos I/agoon:<br />
East-West profile (12 samples).<br />
North-South profile (9 samples).<br />
Channels:<br />
Mamaon Channel (NW. end of Cocos Lagoon, 7<br />
samples).<br />
Manell Channel (into Achang Bay, 4 samples).<br />
Pago Channel (into Pago Bay, 8 samples).<br />
Outer slopes surrounding <strong>Guam</strong> :<br />
(10 samples).<br />
The seven deepest of the outer-slope samples (those<br />
from between 315 and 1,170 ft) provide the richest<br />
assemblages found in the Recent. These seven samples<br />
of globigerine ooze are similar to the samples of Miocene<br />
globigerine ooze from the Janum Formation, but they<br />
differ by having an admixture of shallower water ma<br />
terial from upslope that is not found in the Miocene<br />
samples.<br />
The major differences between the Miocene samples<br />
and the Recent outer-slope samples may be briefly sum<br />
marized as follows: The Recent samples show (a) an<br />
increase in numbers and diversity of arenaceous species;<br />

(b) great increase in abundance of specimens and diver<br />
sity of species of Miliolidae and Ophthalmidiidae; (c)<br />
appearance in some abundance of camerinids and<br />
peneroplids that probably originated upslope; (d) dis<br />
appearance of the family Ellipsoidinidae; (e) appear<br />
ance of species in the families Spirillinidae and<br />
Discorbidae; (f) increase in numbers and diversity of<br />
species in the family Rotaliidae; (g) appearance in<br />
abundance of representatives of the families Amphi-<br />
steginidae, Calcarinidae, and Cymbaloporidae, most of<br />
which also probably originated upslope; (h) decrease in<br />
numbers and diversity of species in the Cassidulinidae;<br />
and (i) appearance of species in the Planorbulinidae,<br />
Rupertiidae, and Homotremidae.<br />
The other four main ecologic subdivisions of Recent<br />
samples beaches, reefs, lagoons, and channels<br />
together contain a composite fauna that differs only<br />
slightly in its four parts but is distinctly different from<br />
the fauna from the outer-slope samples.<br />
The major differences between the deeper samples<br />
from the outer slope and the shallower ones from the<br />
beaches, reefs, lagoons, and channels may be briefly<br />
summarized as follows: The shallower samples show<br />
(a) an increase in abundance of the miliolids; (b) the<br />
complete disappearance of the families Lagenidae, Poly-<br />
morphinidae, Cassidulinidae, Chilostomellidae, Ruper<br />
tiidae, and Ceratobuliminidae; (c) the almost complete<br />
disappearance of the families Heterohelicidae, Spiril<br />
linidae, Robertinidae, Globigerinidae, and Globorota-<br />
liidae; (d) an increase in abundance of the camerinids,<br />
peneroplids, and elphidiids; (e) a decrease in numbers<br />
and diversity of species in the Buliminidae; (f) a nearly<br />
complete absence of all the deeper water species of<br />
Amphisteginidae, leaving only A. madagascariensis ;<br />
and (g) an increase in abundance and robustness of<br />
the three species: Amphixtegina. madagascariensis^ Cal-<br />
carina spengleri, and Baculogypsina sphaerulata.<br />
The Recent beach accumulations are typical of beaches<br />
in the tropical Pacific, being characterized by a pre<br />
dominance of reef-dwelling species Baculogypsina<br />
sphaerulata (Parker and Jones), C alcanna spengleri<br />
(Gmelin), and Marginopora vertebralis Blainville<br />
and by a scarcity of other species. The assemblages col<br />
lected from the reefs, from the lagoons, and from the<br />
channels have little to distinguish them one from an<br />
other. If anything, there is perhaps a greater diversity<br />
of species in the lagoons and channels than on the reefs<br />
and perhaps even a slightly greater diversity in the<br />
lagoons, where the circulation of water is less active than<br />
in the channels.<br />

SMALLER FORAMINIFERA FROM GUAM 113<br />
INCONGRUITIES OF CORRELATIONS IN THE WESTERN<br />
PACIFIC<br />
During the past 10 years a rather detailed zonation<br />
based on planktonic <strong>Foraminifera</strong> has been built up<br />
within the Cretaceous and Tertiary. It originated<br />
mostly in the West Indian region but has been extended<br />
to Europe, Africa, and Asia and is now regarded by<br />
most of its users as having worldwide validity in the<br />
equatorial regions.<br />
Because it was established on the basis of planktonic<br />
<strong>Foraminifera</strong> and without any reference to either larger<br />
<strong>Foraminifera</strong> or mollusks, there is no positive and in<br />
disputable way in which the zonation can be correlated<br />
with either the European time scale or with the Indo<br />
nesian letter classification. Moreover, there is no uni<br />
versal agreement as to where the various zones are to<br />
be placed in terms of either of these other time scales.<br />
Nevertheless, some speculative correlations, as indicated<br />
in figure 2, may be made.<br />
As a fundamental premise to the building up of cor<br />
relations between beds that contain planktonic Fora<br />
minifera, we must accept the hypothesis of worldwide<br />
contemporaneous existence of these zones and their<br />
unchanging sequential relation to one another. Keep<br />
ing in mind that these two assumptions contemporane<br />
ous worldwide existence and unchanging sequence are<br />
the keystone of our whole structure of correlation by<br />
planktonic faunas, we may proceed with tentative specu<br />
lations about some of the correlations in the western<br />
Pacific.<br />
The occurrence of Globigerina nepenthes in the Donni<br />
Sandstone Member of the Tagpochau Limestone on<br />
Saipan and in the Janum Formation on <strong>Guam</strong> raises<br />
the question of the correlation of these two occurrences<br />
and their placement in the worldwide planktonic zona<br />
tion. Estimated age (Todd, 1957, p. 280) of the Donni<br />
Sandstone Member was limited upward by the presence<br />
of Orbulina suturalis and limited downward by the<br />
presence of Globorotalia menardii. In addition, the<br />
presence of Globigerma nepenthes, a species described<br />
from the Donni although already known in the West<br />
Indian section, served to restrict the age more narrowly<br />
through its limitation in the West Indian planktonic<br />
zonation. The resulting estimation of the age of the<br />
Donni Sandstone Member as earliest Miocene was made<br />
in terms of the Globorotalia, mayeri and G. menardii<br />
zones which were at that time regarded as lowermost<br />
Miocene.<br />
Other authors have placed these two zones higher in<br />
the European time scale. The lack of agreement re<br />
garding their age is demonstrated by some of the cur<br />
rent interpretations of these two zones. Drooger (1956,

African sections the approximate boundary between the<br />
upper extent of Globorotalia mayeri and the lower ex<br />
tent of Globorotalia menardii would fall within the up<br />

in his studies in Venezuela that the two zones<br />
Globorotalia mayeri s. 1. and Globorotalia, menardii<br />
s. 1. occupy all of the Vindobonian ( = Helvetian and<br />
Tortonian) and the lower part of the Sarmatian. Stain-<br />
forth (1960, range chart) shows that the upper extent<br />
of Globorotalia mayeri (which would be the top of the<br />
Globorotalia mayeri zone) coincides with the Helvetian -<br />
Tortonian boundary. Bolli (1959, table 1) shows the<br />
boundary between the Globorotalia mayeri and Globo<br />

approximately equivalent to the basal Helvetian. Saito<br />

this boundary coincides with the boundary between the<br />
Helvetian and Tortonian. In Bandy's conception<br />
(1964, text fig. 6) of the Cenozoic planktonic Foramini-<br />
feral zonation, the uppermost extent of the range of<br />
Globigerina nepenthes (which would be the upper<br />
boundary of the Globorotalia menardii zone) coincides<br />
with the Sarmatian-Pontian boundary [but Pontian is<br />
a continental stage in the upper Miocene and therefore<br />
should not enter into correlation by planktonic For-<br />
aminif era], whereas the uppermost extent of the range<br />
of Globorotalia mayeri (which would be the upper<br />
boundary of the Globorotalia mayeri zone) coincides<br />
with the Tortonian-Sarmatian boundary.<br />
Thus it can be seen that there is no universal agree<br />
ment as to where planktonic <strong>Foraminifera</strong> zones are to<br />
be placed in terms of the European time scale. There<br />
is, however, universal acceptance of the contemporane-
<strong>Foraminifera</strong> around <strong>Guam</strong> Continued<br />

stratigraphic relations indicating that the Donni beds<br />

sidered. Another possible explanation of the faunal<br />
similarity of the Donni Sandstone Member of Saipan<br />
and the Janum Formation of <strong>Guam</strong> is that although<br />
equivalent in facies they are not precisely so in age and<br />
that a recurrence of facies brought back the several<br />
planktonic species that appear to have a limited stratigraphic<br />
range. Both the Donni and the Janum contain<br />

FIGURE 2. Speculative correlations between planktonic <strong>Foraminifera</strong> zones, the European time scale, and the Indonesian letter classification.<br />
f era in the Eocene, Oligocene, and Miocene in Indonesia.<br />
An upward extension of the classification (Tertiary g<br />
and h) added later (Leupold and Van der Vlerk, 1931)<br />
was based mostly on lignitic and estuarine f acies. No<br />
reference to planktonic <strong>Foraminifera</strong> was made in either<br />
lower or upper part of the classification. Correlation<br />
between the letter classification and the European time<br />
scale is generally not attempted, particularly in its later<br />
parts, Tertiary e, /, g, and h. Van der Vlerk's state<br />
ment (1955, p. 75), made nearly 30 years after the estab<br />
lishment of the Indonesian letter classification, that<br />
"correlation between Tertiary e and / and the Chat-<br />
tian-Aquitanian-Burdigalian (or Vindobonian) is at<br />
present quite impossible" is still applicable today.<br />
Glaessner (1959, chart 1), however, has indicated a<br />
correlation for the Indo-Pacific region and Australia in<br />
which Tertiary e is shown as equivalent to the upper<br />
part of the Oligocene and the Aquitanian; Tertiary /<br />
equivalent to the Burdigalian, Helvetian, and Torton<br />
ian; Tertiary g equivalent to the Sarmatian and the<br />
lower part of the Pliocene; and Tertiary h equivalent<br />
to the upper part of the Pliocene. In Glaessner's cor<br />
relation table, the Donni Sandstone Member of the<br />
Tagpochau Limestone is shown as belonging in the up<br />
per part of Tertiary / and also as equivalent to the<br />
Tortonian. In terms of the currently accepted approxi<br />
mate age of the planktonic species that are present in<br />
the Donni, this correlation with the Tortonian (and<br />
concurrently with Tertiary /) is a more reasonable one<br />
than that of early Miocene age (and Tertiary e) that<br />
was attributed to the Donni by me in 1957 (Todd, 1957,<br />
p. 280).<br />
The correlation of the Janum with Tertiary g was<br />
originally made upon the basis of the evidence of the<br />
larger <strong>Foraminifera</strong> is discussed on page 17. The abun<br />
dant population of planktonic <strong>Foraminifera</strong> found in<br />
the Janum is also inherently capable of providing a<br />
close age determination for the Janum, although not<br />
directly in terms of the Indonesian letter classification.<br />
The planktonic population of the Janum indicates its<br />
probable placement in one of the zones containing<br />
Globigerina nepenthes.<br />
In terms of Saito's (1962) interpretation of the range<br />
of Globigerina nepenthes, the Janum would fall some<br />
where within the upper Helvetian or lower Tortonian.<br />
In terms of Blow's (1959) interpretation, it would fall<br />
within the "Vindobonian-Sarmatian?." In terms of<br />
Bandy's (1964) interpretation, it would fall between<br />
the middle Burdigalian and the top of the Sarmatian.<br />
In terms of Glaessner's (1959) correlation chart, the<br />
Donni Sandstone Member of the Tagpochau Limestone<br />
(called Donni Tuff on the chart) is equivalent to the<br />
Tortonian and also to the upper part of Tertiary /.<br />
Thus by a two-stage correlation (starting with the as<br />
sumption that the Janum is approximately equivalent<br />
to the Donni and then that the Donni is equivalent to<br />
the Tortonian and to the upper part of Tertiary /) a<br />
possible interpretation as Tertiary / may be arrived<br />
at for the Janum.
All these possible interpretations of age of the Janum,<br />
however, have to be qualified by the tacit understand<br />
ing that there is nothing in the Janum that, per se.<br />
indicates its direct correlation with Tertiary /, with<br />
the Tortonian, or with any other stage of the European<br />
time scale. However, Drooger's (1964) well-taken<br />
point that "the labelling with stage names of deposits<br />
all over the world * * * forms a heavy burden to<br />
progress in stratigraphic correlations," should not in<br />
hibit the attempt to correlate between deposits in dis<br />
tant parts of the world, particularly if it can be done<br />
on the basis of planktonic <strong>Foraminifera</strong>.<br />
Another attempt at correlation by means of plank-<br />
tonic <strong>Foraminifera</strong> in the western Pacific was discussed<br />
by Cole and others (1960). On the island of Yap,<br />
planktonic <strong>Foraminifera</strong> of the Globigerinatella insueta<br />
zone were found in association with larger Foraminif<br />
era. The planktonic <strong>Foraminifera</strong> were correlatable<br />
with those of the Fina-sisu Formation of Saipan, which<br />
in turn had originally been regarded as Tertiary d in age<br />
but without corroboration. The larger <strong>Foraminifera</strong><br />
were indicative of Tertiary / age and correlatable (Cole,<br />
1963, table 3) with the Bonya Limestone of <strong>Guam</strong>,<br />
which is Tertiary / in age, and with beds on Fiji dated<br />
as Tertiary /. After discussing possible explanations<br />
of this dilemma, such as reworking and local expansion<br />
of zones, the question was left unresolved.<br />
In view of present-day understanding of correlation<br />
by planktonic <strong>Foraminifera</strong>, new light may be shed on<br />
this question. The Yap occurrence falls in the Globi<br />
gerinatella insueta/Globigerinoides bispherica subzone.<br />
This zone is correlated with the uppermost Aquitanian<br />
by several authors (Blow, 1959, chart 1; Bolli, 1959,<br />
table 1; Stainf orth, 1960, range chart; Saito, 1963, table<br />
16; Hanzawa, 1964, p. 298; Bandy, 1964, text fig. 5), but<br />
Drooger correlated this zone with the upper part of the<br />
Helvetian (1956, text fig. 1). Only if the youngest esti<br />
mate of age is used for the Globigerinatella insueta<br />
zone namely, the upper part of the Helvetian would<br />
the insueta assemblage be contemporaneous with an<br />
assemblage of larger <strong>Foraminifera</strong> of Tertiary / age.<br />
By placing the Donni in Tertiary / instead of Tertiary<br />
e (as now seems more logical) the dilemma can be re<br />
solved. For then both the insueta/bispherica subzone<br />
and the nepenthes zone would fall into Tertiary /, the<br />
former at the base and the latter at the top. But without<br />
both these assumptions (that is, the Donni being Ter<br />
tiary / and the insueta/bispherica subzone being Ter<br />
tiary /), I cannot explain the Yap occurrence of<br />
insueta/bispherica planktonics in association with Ter<br />
tiary / larger <strong>Foraminifera</strong>. Even though both assem<br />
blages might be placed in Tertiary /, I cannot conceive<br />
of the insueta assemblage, characteristic of the Fina-<br />
SMALLER FORAMINIFERA FROM GUAM 123<br />
sisu, being contemporaneous with the nepenthes assem<br />
blage that is characteristic of the Donni.<br />
FAUNAL REFERENCE LISTS<br />
Two alphabetized lists one for the benthonic species<br />
and one for the planktonic are included to facilitate<br />
reference to the original source or to a systematic<br />
treatise.<br />
For each species that is illustrated a reference to the<br />
plates is included. The figures are grouped into four<br />
divisions, corresponding to the four ages that are stud<br />
ied, and the figures are arranged systematically on the<br />
plates within each of these divisions. Following the<br />
reference, one or more letters are added to indicate the<br />
age or ages in which the species was found: E, Eocene,<br />
O, Oligocene, M, Miocene, and K, Recent. The samples<br />
in which each species was found may be determined<br />
by referring to table 1 for the Eocene, table 2 for the<br />
Oligocene, table 3 for the Miocene, and table 4 for the<br />
Recent. The localities from which the samples were<br />
collected are shown in figure 1 and are given following<br />
the fauna.<br />

Only two specimens of this distinctive species were<br />
found in Recent sample 663 from 972 fathoms off the<br />
northeastern coast of <strong>Guam</strong>. The species appears to be<br />
undescribed but cannot be erected on so few specimens.<br />
The test is rather compressed for the genus. The<br />
costae are high, sharp, and closely spaced and slightly<br />
oblique to the axis of the chamber, thus curved around<br />
at the base of the chamber. The periphery is marked by<br />
one of the costae being about twice as high as the others,<br />
and in the specimen that is not illustrated this costa<br />
is serrate because it is broken. The aperture is sur<br />
rounded by a thickened lip. The illustrated specimen has<br />
a second flaring lip below the main one, a freak develop<br />
ment that gives the specimen the appearance of a double<br />
aperture.<br />

Darbyella&p- R. (PI. 18, fig. 3.)<br />
The illustrated specimen exhibits a combination of<br />
structural features not normally found within a single<br />
specimen. The specimen starts out as a close-coiled<br />
Robulus, involute on both sides, consisting of about eight<br />
chambers and having slightly raised limbate curved<br />
sutures. In its later development, the specimen becomes<br />
progressively more evolute on one side only, and the<br />
sutures lose their limbation and become slightly depressed.<br />
The most unique feature seems to be the lack of a radiate<br />
aperture that is so characteristic of most of the genera<br />
in the family Lagenidae. The present specimen clearly<br />
shows the slit aperture described in the type species of<br />
Darbyella. Moreover, through the clear glassy keel it<br />
can be seen that each previous aperture consisted of a<br />
median slit rather than a series of radial slits, as in<br />
Robulus or Lenticulina. Only a single specimen was<br />
found.<br />

Ellipsopleurostomella sp. M. (PI. 12, fig. 16.)<br />
Only one complete, one incomplete (see pi. 12, fig. 16),<br />
and three fragmentary pieces represent what is probably<br />
an undescribed species in this genus. The species is<br />
cylindrical and elongate, about 0.9 mm in length and<br />
0.2-0.3 mm in diameter, and the sutures show no inden<br />
tation on the surface. The initial end is bluntly pointed<br />
and tapering. The apertural end is rounded, and the<br />
aperture is crescent shaped, having the wall on the con<br />
cave side of the crescent outline slightly raised above<br />
the wall on the convex side. The broken side of the wall<br />
in the illustrated specimen permits a view of the internal<br />
tube that connects the previous apertures. Most of the<br />
sutures are only faintly visible, but it can be seen the<br />
several latest sutures are not equatorial but are curving<br />
and oblique to the axis of the test. This undescribed<br />
species is probably related to Ellipsopleurostomella<br />
stewarti Cushman and Siegfus from the Eocene and<br />
Oligocene Kreyenhagen Shale of California, but it is<br />
considerably slenderer and more elongate.<br />

SMALLER FORAMINIFERA FROM GUAM 129<br />

Holotype, USNM 642256, from Miocene (Tertiary g)<br />
beds of the Janum Formation at Lujuna Point, northeast<br />
coast of <strong>Guam</strong>, <strong>USGS</strong>f25805 (Rrl5-l).<br />
This small and delicate species was found in only one<br />
sample of the Miocene. In the Eocene and Oligocene of<br />
<strong>Guam</strong>, a similar, possibly related, form is found. It<br />
differs mainly by being more tapering, by having a pointed<br />
not blunt initial end, by consisting of two or three more<br />
chambers, and by having a shorter apertural neck. These<br />
specimens are probably not identical with but are possibly<br />
related to or ancestral to Orthomorphina parvula.<br />
