Eunema centralis

Gastropoda - Murchisoniina - Lophospiridae

Taxonomy
Lophospira centralis was named by Ulrich and Scofield (1897) [Ulrich & Scofield's descriptions and figures do not match the type, and probably are a variation of Lophospira perangulata; the type specimens are identical to Lophospira (=Eunema) obliqua.]. It is not a trace fossil.

It was recombined as Eunema centralis by Wagner (1999) and Wagner (2023).
