Three Petalodus teeth are described from the Upper Pennsylvanian rocks of northeastern Kansas. Specimens from the Merriam Limestone Member of the Plattsburg Limestone (Lansing Group, Missourian) and the Brownville Limestone Member of the Wood Siding Formation (Wabaunsee Group, Virgilian) are assigned to P. ohioensis. The third specimen, too fragmentary to assign beyond genus level, was recovered from the Ervine Creek Limestone Member of the Deer Creek Limestone (Shawnee Group, Virgilian). Previous references to petalodonts from Kansas are cited, and the reported occurrences of P. ohioensis document its range throughout almost the entire Upper Pennsylvanian Series of Kansas.
