Abstract

A tooth battery, palatoquadrate, and a gill-arch element of Bobbodus schaefferi were collected from Late Pennsylvanian/Early Permian (Asselian) rocks near Manhattan, Kansas. Depending on the placement of the Pennsylvanian–Permian boundary, this specimen extends the upper limit of the species from the Virgilian (Gzelian) into the Gearyan (Asselian). The new range thus is Kasimovian to Asselian, a 15 my interval. Based on features of the palatoquadrate, the diagnoses of the order Eugeneodontida and the superfamily Caseodontoidea are revised. Bobbodus is the most primitive genus of the order Eugeneodontida.
