Telmasaurus
''Telmasaurus'' is an extinct genus of varanoid lizard from the Late Cretaceous of Mongolia. Fossils have been found from the Djadokha and Barun Goyot Formations that date between the early and middle Campanian stage from approximately 80 to 75 million years ago. The type species ''Telmasaurus grangeri'' was named in 1943.
==Description==
''Telmasaurus grangeri'' was named in 1943 and is now known from several fossils. Only two skulls are known, and the snout region is missing from both. Based on the size of these skulls, ''Telmasaurus'' was larger than other Cretaceous varanoid lizards, approaching the size of modern monitor lizards. Its skull is flatter than most other varanoids. The fusion of two bones in the skull called frontals links ''Telmasaurus'' with other early varanids like ''Paravaranus''. The lacrimal bone of ''Telmasaurus'' has a single hole in it, as do those of other early varanoids. The vertebrae of ''Telmasaurus'' are also known, and the way they attach to each other is very different than the way those of modern monitor lizards do. A small crest running between the eye sockets is a distinguishing feature of the genus.
