Cernina (Eocernina)

Gastropoda - Ampullinidae

Taxonomy

Eocernina was named by Gardner (1934) [Sepkoski's age data: T Than T Eo-m-l]. It is not extant.

It was reranked as Cernina (Eocernina) by Turner (1938), Pacaud and Le Renard (1995).

It was assigned to Ampullospirinae by Marincovich (1977), Squires (1984), Squires (1987); to Naticidae by Zinsmeister (1983), Squires (1988), Squires and Demetrion (1992); to Cernina by Turner (1938), Pacaud and Le Renard (1995); to Neotaenioglossa by Sepkoski (2002); and to Ampullospiridae by Kase and Ishikawa (2003).
