It is known from the holotype MNHN.F.MCL-1 an articulated partial postcranial skeleton. It was collected by D. Sigogneau-Russell and D. Russell in 1970 in the upper part of the M2 Member, Grès Rouge Group, in the Rodez Basin, near the village of Valady (département of Aveyron), in Occitanie Region. It was first named by Robert R.

==Etymology== Ruthenosaurus is named after a Gallic regional tribe, Ruthenie (in Medieval Latin), that have also given Ruthénois, the name of the inhabitants of the town of Rodez; and the Ancient Greek sauros, "lizard". The type species is named in honour of Drs Denise Sigogneau-Russell and Donald E. Russell, the original collectors of the holotype.
