Sauravus
''Sauravus'' is an extinct genus of nectridean lepospondyl 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. 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. ''Sauravus cambrayi'' is known from Les Télots, a mine near Autun, Saône-et-Loire, France. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Prehistoric Amphibians
This list of prehistoric amphibians is an attempt to create a comprehensive listing of all genera from the fossil record that have ever been considered to be amphibians, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful ('' nomina dubia''), or were not formally published (''nomina nuda''), as well as junior synonyms of more established names, and genera that are no longer considered amphibians. Modern forms are excluded from this list. The list currently includes 454 names. Naming conventions and terminology Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Junior synonym: A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the type specimens are later assigned to the same genus, the first to be published (in chronological order) is the senior synon ...

Scincosaurus
''Scincosaurus'' is an extinct genus of nectridean lepospondyl within the family Scincosauridae. History ''Scincosaurus crassus'' was first described by Bohemian paleontologist Antonín Frič in volume 1875 of "''Sitzungsberichte der königlichen Böhmischen Gesellschaft der Wissenschaften in Prague''", which at that time was the premiere scientific journal of Bohemia (the modern day Czech Republic). Frič's contribution to this volume was a list of Carboniferous animals he and his associates recently discovered at coal gas mines near the localities of Nýřany and Kounová. His list included short preliminary descriptions for many new genera and species of tetrapods, including '' Microbrachis, Branchiosaurus, Hyloplesion'' (at that time called ''Stelliosaurus''), and ''Sparodus.'' ''Scincosaurus crassus'' was among the new tetrapods from Nýřany, and its short description (erroneously) considered it a robust lacertilian ( lizard), possibly related to ''Sparodus''. A m ...

Carboniferous
The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago. The name ''Carboniferous'' means "coal-bearing", from the Latin '' carbō'' ("coal") and '' ferō'' ("bear, carry"), and refers to the many coal beds formed globally during that time. The first of the modern 'system' names, it was coined by geologists William Conybeare and William Phillips in 1822, based on a study of the British rock succession. The Carboniferous is often treated in North America as two geological periods, the earlier Mississippian and the later Pennsylvanian. Terrestrial animal life was well established by the Carboniferous Period. Tetrapods (four limbed vertebrates), which had originated from lobe-finned fish during the preceding Devonian, became pentadactylous in and diversified during the Carboniferous, including early amphibian line ...

Montceau-les-Mines
Montceau-les-Mines () is a commune in the Saône-et-Loire department in the region of Bourgogne-Franche-Comté in eastern France. It is the second-largest commune of the metropolitan Communauté urbaine Creusot Montceau, which lies southwest of the city of Dijon. History Montceau-les-Mines is a former mining city. Coal was discovered in the area in the 16th Century. A hamlet called "Le Montceau" developed from this discovery. "Le Montceau" began to grow after the building of the Canal du Centre, built between 1783 and 1791. A business entity, "Compagnie des mines", started to extract coals in 1833. The commune was officially established June 24, 1856. as Montceau-les-Mines, a community of 1300 inhabitants, drawn from a territory formed from the villages of Blanzy, Saint-Vallier, Saint-Berain-sous-Sanvignes, and Sanvignes-les-Mines. A graveyard and a church were built by the principal coal company, a sign of paternalism of mining industry. Intense social movements took place a ...

Artinskian
In the geologic timescale, the Artinskian is an age or stage of the Permian. It is a subdivision of the Cisuralian Epoch or Series. The Artinskian likely lasted between and million years ago (Ma) according to the most recent revision of the International Commission on Stratigraphy (ICS) in 2022. It was preceded by the Sakmarian and followed by the Kungurian. Stratigraphy The Artinskian is named after the small Russian city of Arti (formerly ''Artinsk''), situated in the southern Ural mountains, about 200 km southwest of Yekaterinburg. The stage was introduced into scientific literature by Alexander Karpinsky in 1874. Base of the Artinskian The base of the Artinskian Stage is defined as the first appearance datum (FAD) of the conodont species '' Sweetognathus whitei'' and ''Mesogondolella bisselli''. In order to constrain this age, the ICS subcommission on Permian stratigraphy informally proposed a candidate GSSP in 2002, later followed by a formal proposal in 201 ...

Autun
Autun () is a subprefecture of the Saône-et-Loire department in the Bourgogne-Franche-Comté region of central-eastern France. It was founded during the Principate era of the early Roman Empire by Emperor Augustus as Augustodunum to give a Roman capital to the Gallic people Aedui, who had Bibracte as their political centre. In Roman times the city may have been home to 30,000 to 100,000 people, according to different estimates. Nowadays, the commune has a population of about 15,000. Geography The commune lies in the northwest of the department. History Early history Augustodunum was founded during the reign of the first Roman emperor, Augustus, after whom it was named. It was the civitas "tribal capital" of the Aedui, Continental Celts who had been allies and "brothers" (') of Rome since before Julius Caesar's Gallic Wars. Augustodunum was a planned foundation replacing the original oppidum Bibracte, located some away. Several elements of Roman architecture such as wall ...

Stephanian (stage)
The Stephanian is a stage in the regional stratigraphy of northwest Europe with an age between roughly 304 and 299 Ma (million years ago). It is a subdivision of the Carboniferous system or period and the regional Silesian series. The uppermost units of the Coal Measures of England and Wales are probably of Stephanian age, though the larger part of this formation is referred to the earlier Westphalian. The stage derives its name from the city of Saint-Étienne for its coal mining basin in eastern central France (which itself derives from associations with Saint Stephen) where strata of this age occur. In the official geologic timescale of the ICS, the Stephanian is placed within the Pennsylvanian epoch (318-299 Ma).F M Gradstein, J G Ogg, A G Smith et al 2004, ‘A Geologic Time Scale 2004’. The (regionally defined) Stephanian stage corresponds to the (internationally used) Gzhelian. References appear in scientific literature to a Stephanian epoch or Stephanian series Ser ...
