Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| S. Jouve et al. 2005 | Dyrosaurid with about 20 to 21 robust but sharp teeth on the upper tooth row (on each ramus); teeth moderately elongated, with a posterior carina which ends before reaching the base of the teeth (not in the more posterior teeth), buccal and lingual surface smooth or lightly striated; interfenestral bar very narrow (sagittal crest); supraoccipital, with parietal, tapers posteriorly between the two occipital tuberosities; occipital tuberosities well developed, and dorsoventrally flattened; suture between basioccipital and exoccipital (posteriorly to basioccipital tuberosities) deeply within a groove; mandibular symphysis long, wider than high in its median part, and ending posteriorly at the level of the sixteenth tooth; splenials end dorsally between the level of the tenth and the eleventh tooth. Differs from Dyrosaurus in having less numerous, and more massive teeth, a narrower interfenestral bar, a posterior wall of the supratemporal fenestra very inclined dorsally, the occipital tuberosities dorsoventrally flattened, and the supraoccipital which tapers posteriorly; from Congosaurus in having a longer snout, more massive and more widely separated teeth; from Hyposaurus in having a longer snout, and more massive teeth, more ventrally projected basioccipital tuberosities, and the supraoccipital which tapers posteriorly; from Rhabdognathus in having more ventrally projected basioccipital tuberosities, the occipital tuberosities dorsoventrally flattened, and the supraoccipital which tapers posteriorly. |
