Classification

Originally described as a South American representative of the genus Pareiasaurus, it was assigned to a new genus Provelosaurus by Lee (1997), who noted it shows more affinities with the small, highly derived, South African dwarf pareiasaurs (called Pumiliopareiasauria by Jalil & Janvier 2005 ) than with the more typical Pareiasaurus. According to Lee, Provelosaurus bridges the morphological gap between the advanced South African and the more generalized pareiasaurs. The African and Brazilian fauna is often very similar.
