Gastropods and Rostroconchs (Mollusca) from the Maxville Limestone (Upper Mississippian) in Ohio

Abstract

The gastropod fauna is abundant and more diverse in the Upper Mississippian Maxville Limestone than previously described. Seventeen species, including 6 reported for the first time, are known and fragments of several others indicate a still larger fauna is present. A taxonomic update of earlier work includes the new species Platyceras (Orthonychia) morsei, Stegocoelia (Hypergonia)? jonathanensis, and Acteonina hanseni. Small, poorly preserved specimens of rostroconchs represent the genus Oxyprora.
