New Species of Sepiida (Mollusca, Cephalopoda) from the Eocene of the Gulf Coast

Abstract

One species of Belemnosella Naef, 1922, and three species of Belosaepia Voltz, 1830, are described as new. Reports of both genera from the Jackson Group, upper Eocene, raise the stratigraphic range of each to that level from the previously reported Claiborne Group, middle Eocene age.
