In the revised Treatise this family is to be expanded to include at least six subfamilies, each containing several genera. It is the oldest non-ribbed family in the evolution of the Productoidea, appearing in the Emsian, but varied ribbing developed in a few subfamilies, such as the Productininae late in the Devonian. The Leioproductidae differ mainly in having deep body cavities. Subfamily PRODUCTININAE Muir-Wood & Cooper
