Sauravus is an extinct genus of nectridean tetrapodomorphs within the family Scincosauridae.
Species
The type species of Sauravus, Sauravus costei, is known from Blanzy, a town in the Saône-et-Loire department of France.{{Cite journal|last=Thévenin|first=Armand|date=1906|title=Amphibiens et reptiles du terrain Houiller de France|url=https://books.google.com/books?id=3BQepZLdF8YC|journal=Annales de Paléontologie|volume=1|pages=12–19}} This town and its adjacent community Montceau-les-Mines possess a Lagerstätte containing abundant Carboniferous fossils. Fossils from the Montceau-les-Mines lagerstätte are believed to have been from the Stephanian B stage of the Late Carboniferous, approximately 305 to 304 million years ago.{{Cite journal|last1=Lojka|first1=Richard|last2=Drábková|first2=Jana|last3=Zajíc|first3=Jaroslav|last4=Sýkorová|first4=Ivana|last5=Franců|first5=Juraj|last6=Bláhová|first6=Anna|last7=Grygar|first7=Tomáš|date=2009-09-01|title=Climate variability in the Stephanian B based on environmental record of the Mšec Lake deposits (Kladno–Rakovník Basin, Czech Republic)|journal=Palaeogeography, Palaeoclimatology, Palaeoecology|language=en|volume=280|issue=1–2|pages=78–93|doi=10.1016/j.palaeo.2009.06.001|bibcode=2009PPP...280...78L |issn=0031-0182}}
Sauravus cambrayi is known from Les Télots, a mine near Autun, Saône-et-Loire, France.{{Cite journal|last=Thévenin|first=Armand|date=1910|title=Les plus anciens quadrupeds de France|url=http://bibliotheques.mnhn.fr/EXPLOITATION/infodoc/digitalCollections/viewerpopup.aspx?seid=ANPAL_S000_1910_T005_N000|journal=Annales de Paléontologie|volume=5|pages=43–46}} 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 age, about 290 to 286 million years ago.{{Cite journal|last=Spindler|first=Frederik|date=July 9, 2015|title=The basal Sphenacodontia – systematic revision and evolutionary implications|url=http://www.qucosa.de/fileadmin/data/qucosa/documents/17174/Spindler_1b.pdf|journal=Dissertation}}
Sauravus spinosus is a rename of Scincosaurus spinosus, a Montceau-les-Mines scincosaurid described by C. Civet in 1982.{{Cite journal|last=Civet|first=C.|date=1982|title=Étude d'un nouvel amphibien fossile du bassin houiller de Montceau-les-Mines, Scincosaurus spinosus nov. sp.|journal=La Physiophile |publisher=Société d'Études des Sciences Naturelles et Historiques de Montceau-les-Mines|volume=96|pages=73–79}} Although that author considered the species to belong to Scincosaurus, in 1994 Jean-Michel Dutuit and D. Heyler considered it a species of Sauravus.{{Cite journal|last1=Dutuit|first1=Jean-Michel|last2=Heyler|first2=D.|date=1994|title=Rachitomes, Lépospondyles et Reptiles due Stephanien (Carbonifere superieur) du basin de Montceau-les-Mines (Massif central, France)|journal=Mémoires de la Section des Sciences|volume=12|pages=249–266}}
