Palaeovaranus lismonimenos
Taxonomy
Palaeovaranus lismonimenos was named by Georgalis et al. (2021). Its type specimen is NHMW 2019/0047/0001 (incomplete parietal) and is a 3D body fossil. Its type locality is Phosphorites du Quercy (for taxa with non-specific locality data), which is in an Eocene/Miocene terrestrial phosphorite in the Quercy Phosphorites Formation of France.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| G. L. Georgalis et al. 2021 | The parietal of Palaeovaranus lismonimenos n. sp. differs from that of Palaeovaranus cayluxi by the following distinguished features and the combination of features: 1) the dorsolateral crests are rather distinct, extending posterolaterally and dorsally, and their margins are distinctly crenulated; 2) the median crest is short (shorter than the length of the median triangular field measured in the median plane) and its posterior tip fits between the anterolateral processes of the triangular median field; 3) the anterior ends of the dorsolateral crests extend to the tips of the anterolateral processes; 4) the ornamentation of the parietal consists of small, more or less densely arranged mounds having more or less distinctly developed crest; and 5) the anterior margin of the parietal fossa lies anterior to the level of the junctions of the anterolateral margins of the su- pratemporal processes with the parietal plate. |
