In 2000, Spencer and Benton found Contritosaurus to be junior synonym of Phaanthosaurus. C. simus Ivakhnenko, 1974 which is known from the holotypePIN 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 junior synonym of P. simus.[4] Recent cladistic analyses by Juan Carlos Cisneros, 2008 and Mark J. Macdougall and Sean P. Modesto, 2011 accepted this synonymy.[5][6]
