Abstract

Heslerodus divergens and an undetermined species of the genus Ossianodus are recorded for the first time from the Upper Pennsylvanian LaSalle Limestone Member of the Bond Formation in northern Illinois. Ossianodus is a new record for the state. Four specimens of H. divergens and one of Ossianodus sp. were recovered, all partially complete teeth. Descriptive and comparative notes are provided. Future studies of the formation may yield additional specimens of other vertebrate species.
