Abbasites is an extinct genus of ammonites from the early Middle Jurassic epoch, included in the ammonitid family Erycitidae.[2]
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 [3]
Abbasites was originally described by Sydney S. Buckman in 1921,[3][4] 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 Stephanoceratoidea, according to Westermann (1965)[5][6] and Imlay (1984)[5] but was previously placed in the Hildoceratoid family Hammatoceratidae by Arkell et al. (1957).[3] It is currently regarded as a full genus in the Erycitidae subfamily Erycitinae.[7][8] 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.[9]
