Taxonomy
Ceratopea was named by Ulrich (1911) [Sepkoski's age data: O Trem-u - O Aren-u. Sepkoski's reference 797]. It is not extant.
It was assigned to Ceratopeidae by Yochelson and Bridge (1957); to Pleurotomariacea by Knight et al. (1960); to Ophiletidae by Morris and Cleevely (1981); to Euomphalina by Sepkoski (2002); and to Raphistomidae by Yochelson and Copeland (1974), Wagner (1999) and Bouchet et al. (2005).
