The first Autunian vertebrate remains are described from the Largentiere Basin, in a well core from the drilling site at Morte-Merie (Geologie Profonde de la France program). Pollen and a branchiopod crustacean found nearby in the core, as well as tetrapod footprints and plants from outcrops, indicate an Autunian age. Sedimentologic analyses reveal a shallow lacustrine deposit. Despite its fragmentary condition, the fossil is determined as a subadult palaeoniscoid close to lacustrine Upper Palaeozoic forms. Its singularity helps to confirm that the Largentiere Basin is part of the "Permian palaeobiogeographic province of South Massif central", but its potential palaeontological relationships suggest that communications were possible with the North Massif central and Middle Europe.
