***Sauravus*** is an extinct [genus](/source/Genus) of [nectridean](/source/Nectridea) [tetrapodomorphs](/source/Tetrapodomorph) within the [family](/source/Family_(taxonomy)) [Scincosauridae](/source/Scincosauridae).

## Species

The type species of *Sauravus, Sauravus costei,* is known from [Blanzy](/source/Blanzy), a town in the [Saône-et-Loire](/source/Sa%C3%B4ne-et-Loire) department of [France](/source/France).[1] This town and its adjacent community [Montceau-les-Mines](/source/Montceau-les-Mines) possess a [Lagerstätte](/source/Lagerst%C3%A4tte) containing abundant Carboniferous fossils. Fossils from the [Montceau-les-Mines lagerstätte](/source/Montceau-les-Mines_lagerst%C3%A4tte) are believed to have been from the [Stephanian B](/source/Stephanian_(stage)) stage of the Late Carboniferous, approximately 305 to 304 million years ago.[2]

*Sauravus cambrayi* is known from [Les Télots](https://fr.wikipedia.org/wiki/Mine_des_T%C3%A9lots), a mine near [Autun](/source/Autun), Saône-et-Loire, France.[3] Télots is the type locality of the Autunian stage, a period of time which is believed to correspond to part of the early Permian period. The geological formation which Télots fossils belong to is known as the Millery Formation. The specific part of the Permian which this formation belongs to was unclear for many years. In 2014, Schneider *et al.* suggested that the Millery Formation dated to the middle [Artinskian](/source/Artinskian) age, about 290 to 286 million years ago.[4]

*Sauravus spinosus* is a rename of *Scincosaurus spinosus*, a Montceau-les-Mines scincosaurid described by C. Civet in 1982.[5] Although that author considered the species to belong to *[Scincosaurus](/source/Scincosaurus)*, in 1994 Jean-Michel Dutuit and D. Heyler considered it a species of *Sauravus*.[6]
