Description
Abbasites is small and subglobular with ribbing that divides high on its sides and which has an interruption on the venter that replaces the keel, generally characteristic of the Hammatoceratidae
Classification
Abbasites was originally described by Sydney S. Buckman in 1921, with A. abbas as its type species, and was considered by some to be a subgenus of Erycites. Abbasites was included in the Otoitidae, the ancestral family of the Stephanocerataceae, according to Westermann (1965) and Imlay (1984) but was previously placed in the Hildoceratacean family Hammatoceratidae by Arkell et al. (1957). It is currently regarded as a full genus in the Erycitidae subfamily Erycitinae. The genus Erycites is believed to be ancestral to Abbasites. However, Abbasites is believed to have left its own descendants in the ammonite family Otoitidae.
