Phaanthosaurus is an genus of basal from early Triassic (Induan stage) deposits of Nizhnii Novgorod, . It is known from the holotype 1025/1, a mandible (a dentary). It was collected from Vetluga River, Spasskoe village and referred to the Vokhmian terrestrial horizon of the Vokhma Formation. It was first named by P. K. Chudinov and B. P. Vjushkov in 1956 and the type species is Phaanthosaurus ignatjevi. In 2000, Spencer and Benton found Contritosaurus to be of Phaanthosaurus. C. simus Ivakhnenko, 1974 which is known from the holotype 3355/1, a partial skull with right mandible from the same location, and from three paratypes, was recombined as P. simus. They also found that the second species of Contritosaurus, C. convector (PIN 3357/1, a mandible) is a of P. simus. Recent analyses by Juan Carlos Cisneros, 2008 and Mark J. Macdougall and Sean P. Modesto, 2011 accepted this synonymy.
