Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. L. Georgalis et al. 2021 | The parietal of Palaeovara- nus cayluxi differs from that of the sole other recognized species of the genus, Palaeovaranus lismonimenos n. sp., described below, in the following distinguished characters and the combination of features: 1) presence of a long median crest (longer than the length of the median triangular field measured in the median plane); 2) dorsolateral crests are low and without crenulations; 3) anterior end of the dorsolateral crests disappears on the dorsal surface of the root of the anterolateral process; 4) the ornamenta- tion is weakly developed consisting of only several low ridges of various lengths running medially to the medial margins of the dorsolateral crests, as well as small mounds; and 5) the anterior margin of the parietal fossa lies at or posterior to the level of the junctions of the anterolateral margins of the supratemporal processes with the parietal plate. |
