Diablophis is a genus of Late Jurassic stem-snake from the Morrison Formation of North America. The type and only species, D. gilmorei was once thought to be a species of Parviraptor[2] but is now classified as its own genus.[1] The animal is known from multiple specimens, the holotype being LACM 4684/140572, which consists of a broken right mandible, broken right maxilla and broken axis vertebrae. A number of other specimens have also been attributed to Diablophis, including LACM 4684/140572 and LACM 5572/120732, the specimens previously attributed to Parviraptor and LACM 4684/120472.[1]
Phylogeny
Diablophis has been recovered as a basal snake, though this placement is disputed. The cladogram from figure 4b in Caldwell et al.'s 2015 study is replicated below.[1]
