Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Clark and R. L. Carroll 1973 | Large romeriid captorhinomorph. Skull roof deeply sculptured with uniformly distributed oval pits. Tabulars lost. Posterior margin of parietals shallowly concave. Supratemporal extending down along top half of the posterior margin of the squamosal. Posterior margin of the squamosal nearly vertical. Postorbital large and extending onto skull roof. Pineal opening large. Premaxilla down-turned. Four to five teeth in premaxilla, 18 to 22 in maxilla; fourth or fifth is enlarged “canine.” No evidence of more than a single tooth row. Ossified portion of opisthotic not reaching squamosal. Supraoccipital constricted laterally to form margins of large posttemporal fenestrae. Very slight retroarticular process. Neural arches in trunk region approaching configuration noted in Captorhinus. Zygapophyses nearly horizontal. |
