Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. A. Suarez et al. 2021 | Small pycnodont with prearticular teeth generally like those of other Anomoeodus species. Main prearticular teeth elongate and reniform, distinct in being more compressed, elongate, S-shaped, and interspaced than in other Anomoeodus taxa. Lateral prearticular teeth oval to reniform and partially intercalated. Crimped-wall and coronal furlough very weakly-developed on all teeth. Second lateral row on prearticular has an anteromedial-tip that points weakly forward and caudo-lateral tip that points slightly backward. |
