Family: Neocomitidae

Neocomitidae is a family of Lower Cretaceous ammonitids comprising genera with strongly ribbed evolute (all whorls exposed) to smooth, fairly involute (inner whorls mostly hidden) shells.

In the 1967 description of the family[1] Neocomitidae was regarded as the subfamily Neocomitinae within the Berriasellidae, a family within the Perisphinctoidae that ranged from the Late Jurassic into the Early Cretaceous. In a more recent treatment [2] berriaselids are regarded as a subfamily within the Neocomitidae.

Current opinion differes from the 1967 placement of Neocomitidae in the Perisphinctoidea[1] but rather includes it in the superfamily Endemoceratoidea.[3][4]
