Species Dicarinella concavata Brotzen 1934


Discussion / Comments:
Caron (1985):
Lateral view clearly asymmetrical, concavo-convex, with early chambers globular shaped and late chambers of the outer whorl with two close keels. Compared with D. asymetrica no keel surrounds the umbilicus. It differs from D. primitiva in having more strongly inflated chambers on the umbilical side.
