Branchiosaurs are rare in the lacustrine fauna from the Lower Permian of Buxières-les-Mines (Massif Central, France). All known specimens belong to Melanerpeton gracile, which is significant for the Melanerpeton gracile-Discosauriscus pulcherrimus zone in the biostratigraphical zonation of Upper Carboniferous and Lower Permian based on aquatic amphibians. This branchiosaurid species support the Asselian age (uppermost Lower “Autunian”/Rotliegend) of the Assise de Buxières in the Bourbon l’Archambault Basin (Allier, France).
