Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. L. Cione et al. 2007 | (based only on tooth plates). Tooth plates of medium size, high crowned and with sharp, slender and acute ridges that originate anteriorly; five ridges in the upper plates and four ridges in the lower plates; restricted pulp cavity; occlusal tubercles absent; limited mantle dentine visible on occlusal surface; punctations simple (petrodentine sensu Kemp, 200 I absent) and not arranged with a particular pattern. Tooth plates most resemble those of Ptychoceratodus and Ferganaceralodus but differ from them in that the inner apex it is not so well defined, it is rounded, a larger angle is usually formed by first and last ridges, and the ridges are more slender and acute. |
