«Material. Upper Bathonian of Tongobory: 1 LV (internal mould) (BSPG 2015 XIII 177).
Description and remarks. Specimen small (H: 10.9 mm; L: 10.8 mm), suborbicular, inequilateral, moderately inflated. Auricles well developed, distinctly set off from disc, anterior auricle with byssal notch. Disc covered with around 20 radial ribs, separated by interstices that are wider than the ribs.
Despite its poor preservation, the specimen can be firmly placed in Spondylopecten (S.) palinurus according to the diagnosis of the species given by Johnson (1984).» FÜRSICH, F. T. , M. HEINZE & W.

Material: 2 right valves from AL1. Remarks: Johnson (1984) distinguished S. palinurus from all other species of S. (Spondylopecten) by the low number of radial plicae (26 or less). The two specimens from Ethiopia have 22 plicae respectively and therefore fall within this range. The rows of spines of the figured specimen are only preserved in the anteriormost ribs due to abrasion.» KIESSLING, W., D. K. PANDEY, M. SCHEMM-GREGORY & M. ABERHAN. 2011.

«2. AMENDED DIAGNOSIS
Distinguished from all other species of S. (Spondylopecten) by the number of plicae (26 or less).
3. AMENDED DESCRIPTION
Disc sub-orbicular at all sizes (text fig, 76), maximum height 62 mm (DE LORIOL, 1894). Umbonal angle very variable (text fig. 78) but increasing (at a decreasing rate) during ontogeny to produce concave dorsal margins, Disc flanks moderately high.
Equilateral; equivalve, convexity variable, moderate to high, apparently increasing allometrically at a faster rate in earlier representatives (text fig. 77). Intersinal distance greater in left valve than right; moderately large juvenile byssal notch becoming relatively smaller during ontogeny. Auricles well demarcated from disc, moderate in size, anterior larger than posterior. Anterior auricles meeting hinge line at about 90°, posterior auricles meeting hinge line at an obtuse angle. Right anterior auricle meeting disc at an obtuse angle; remaining auricles meeting disc at an acute angle. Right anterior auricle bearing between 5 and 8 radial costae. All auricles sloping downwards from umbo towards opposite valve (PI. 3, Fig. 8). Both valves bearing between 18 (? 16, see Section 4) and 26 rounded radial plicae; modal number apparently increasing phyletically (text fig. 79); plicae slightly wider than sulci in right valve, converse in left valve. Plicae bearing 4 rows of short, closely spaced spines, directed ventrally (PI. 3, Fig. 14). Cardinal area of right valve bearing 2 peg-shaped crura, anterior larger than posterior (ROEDER, 1882, pl. 2, fig. 4). Shell thickness moderate to high; plical amplitude reduced on shell interior.» JOHNSON, A. L. A. 1984.
