Sauravus is an extinct genus of nectridean tetrapodomorphs within the family Scincosauridae.
The type species of Sauravus, Sauravus costei, is known from Blanzy, a town in the Saône-et-Loire department of France. [1] This town and its adjacent community Montceau-les-Mines possess containing abundant Carboniferous fossils. These fossils are believed to have been from the Stephanian B stage of the Late Carboniferous, approximately 305 to 304 million years ago. [2]
Sauravus cambrayi is known from Les Télots, a mine near 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 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 , in 1994 Jean-Michel Dutuit and D. Heyler considered it a species of Sauravus. [6]

The following is a list of the 29 cantons of the Saône-et-Loire department, in France, following the French canton reorganisation which came into effect in March 2015:
Neosaurus is an extinct genus of pelycosaur-grade synapsids from the Late Carboniferous-Early Permian of the Jura region of France. It is known only from a partial maxilla or upper jaw bone and an associated impression of the bone. The teardrop shape of the teeth in the jaw indicate that Neosaurus belongs to the family Sphenacodontidae, which includes the better-known Dimetrodon from the Southwestern United States. The maxilla was first attributed to an early diapsid reptile in 1857, and later a crocodylomorph in 1869, before finally being identified as a sphenacodont synapsid in 1899, a classification that still holds today.
Araeoscelidia or Araeoscelida is a clade of extinct diapsid reptiles superficially resembling lizards, extending from the Late Carboniferous to the Early Permian. The group contains the genera Araeoscelis, Petrolacosaurus, the possibly aquatic Spinoaequalis, and less well-known genera such as Kadaliosaurus and Zarcasaurus. This clade is usually considered to be the sister group to all later diapsids.
The Canal du Centre, originally known as the Canal du Charollais, is a French canal running from Digoin, where it now joins the Canal latéral à la Loire, to the Saône at Chalon-sur-Saône. It was opened in 1792 and was the first watershed canal allowing boats to pass from the north of France to the south. It is 112.1 kilometres (69.7 mi) long and has 61 locks. Most of its traffic was generated by now abandoned coal mines at Montceau-les-Mines.
Saint-Forgeot is a commune in the Saône-et-Loire department in the region of Bourgogne-Franche-Comté in eastern France. It is located north of Autun.
Savianges is a commune in the Saône-et-Loire department in the region of Bourgogne-Franche-Comté in eastern France.
Actinodon is an extinct genus of eryopoidean temnospondyl within the family Eryopidae.
The Communauté urbaine Creusot Montceau is the communauté urbaine, an intercommunal structure, centred on the cities of Le Creusot and Montceau-les-Mines. It is located in the Saône-et-Loire department, in the Bourgogne-Franche-Comté region, eastern France. It was created in 1970. Its area is 742.0 km2. Its population was 93,072 in 2018, of which 21,491 in Le Creusot and 17,897 in Montceau-les-Mines.
Le Creusot TGV station is a railway station on the LGV Sud-Est providing TGV high-speed train services to the city of Le Creusot, Saône-et-Loire, France. It was inaugurated on 22 September 1981 by President François Mitterrand and opened to commercial service five days later. The station, located outside the city in the commune of Écuisses, is accessible by road.
Montcellia is an extinct genus of nectridean tetrapodomorphs within the family Urocordylidae that lived in the late Carboniferous period in the modern France.
Scincosaurus is an extinct genus of nectridean tetrapodomorphs within the family Scincosauridae.
Callibrachion is an extinct genus of caseid synapsids that lived in east-central France during the Lower Permian (Asselian). The holotype and only known specimen (MNHN.F.AUT490) is represented by an almost complete postcranial skeleton associated with skull fragments discovered at the end of the 19th century in the Permian Autun basin in Saône-et-Loire department, in the Bourgogne-Franche-Comté region. It belongs to an immature individual measuring less than 1.50 m in length. Callibrachion was long considered a junior synonym of the genus Haptodus and classified among the sphenacodontid pelycosaurs. In 2015, a new study found that Callibrachion was a different animal from Haptodus and that it was a caseasaur rather than a sphenacodontid. This was confirmed in 2016 by a cladistic analysis which recovered Callibrachion as a basal caseid. Callibrachion's sharp teeth and unenlarged ribcage indicate that this animal was likely faunivorous.
The 5th constituency of the Saône-et-Loire is a French legislative constituency in the Saône-et-Loire département.
Frédéric Delafond was a French geologist and mining engineer.
François Cyrille Grand'Eury was a French geologist, paleontologist and mathematics teacher.
The canton of Montceau-les-Mines is an administrative division of the Saône-et-Loire department, eastern France. It was created at the French canton reorganisation which came into effect in March 2015. Its seat is in Montceau-les-Mines.
Narindasaurus is a genus of turiasaurian sauropod dinosaur from the Middle Jurassic Isalo III Formation of Madagascar. The type species, N. thevenini was formally described by Royo-Torres et al. in 2020. The holotype, which consists of one specimen, is currently stored at the Muséum national d’Histoire naturelle and has been since 1906 or 1907.
Chabardella is an extinct genus of mantis shrimp which lived during the Late Carboniferous in France. It was named in 2009, with C. spinosa as the type and only species.
