(1999), Lee and Caldwell (2000), Houssaye et al. (2013) and Caldwell et al. (2021).

It was assigned to Lepidosauria by Zittel (1890); to Reptilia by Cope (1869), Cope (1871), Cope (1875), Gadow (1898) and Perrier (1928); to Squamata by Woodward (1898), Hay (1902) and Swinton (1934); to Lacertilia by Huene (1954); to Varanoidea by Comaschi Caria (1957), Lee and Caldwell (2000) and Houssaye et al.
