Image de Echinopelta McLean 1989

Description :

This group is quite angular in appearance and has the lines beginning on a raised platform at the base of the shell. In this form the lines become indistinct for most of the shell. The aperture is slightly flared and has a narrow rim. We believe this morphotype corresponds to Echinopelta fistula, which has the same raised platform on the base (see SEM photo above).
