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. [1]
In the 1957 description of the family [2] Neocomitidae was regarded as the subfamily Neocomitinae within the Berriasellidae, a family within the Perisphinctoidea that ranged from the Late Jurassic into the Early Cretaceous. In a more recent treatment [3] berriaselids are regarded as a subfamily within the Neocomitidae.
Current opinion differers from the 1967 placement of Neocomitidae in the Perisphinctoidea [2] but rather includes it in the superfamily Endemoceratoidea. [4] [5]
