Caseodus

Caseodus is an extinct genus of eugeneodont from the Carboniferous of what is now the Midwestern United States, and potentially the Early Triassic of what is now British Columbia, Canada. The genus contains two Carboniferous species, C. basalis and C. eatoni, which are differentiated by the anatomy of their teeth but are otherwise identical. A third species, C. varidentis, is known from the Early Triassic Sulphur Mountain Formation, but due to its wildly different skull and tooth morphology it is questionable if it belongs in the genus. The genus name is in honor of paleoichthyologist Gerard C
