Permian France

Neosaurus ('New Lizard') 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 i

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 pelyco

Aeduella is an extinct genus of freshwater ray-finned fish that lived during the Gzhelian (Late Pennsylvanian, Carboniferous ) and Asselian-Sakmarian (Cisuralian/early Permian epoch) ages in what is now France (Auvergne, Burgundy and Aveyron), Germany (Baden-Württemberg, Rhineland-Palatine, Saarland), Switzerland (Basel-Landschaft, Zürich) and the Czech Republic.
