Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. A. Frederickson and R. L. Cifelli 2017 | Moderate-sized species of Ceratodus, slightly smaller than C. gustasoni, which it resembles in having little surface relief on tooth plate crowns, lack of denticles on ridge crests, obvious circumdenteonal islands present on occlusal surface, and ridges that narrow and are pointed labially. Differs from C. gustasoni and other flat-plated North American species of Ceratodus in having less obtuse C 1 -C p angle, slightly better-developed ridge crests, serrated labial plate margin (angulate ridge termini separated by angulate notches), and presence of prominent vertical wear facets between ridges. |
