Abstract

An unusually complete large pycnodont fish from the Mooreville Chalk of Green County, Alabama, is figured and compared to several previously described specimens. Material from the specimen apparently places Grypodus Hay = Ancistrodon Roemer, Hadrodus Leidy, and Propenser Applegate into synonymy. The specimen is referred to Hadrodus hewletti (Applegate). A complete dentition is present and most of the thick, tuberculated ganoid scales that covered the body are preserved. Exact location of the dorsal fin has been determined and many of the fragile gill rakers are represented.
