Parviraptor was a genus of stem-snake (clade Ophidia)[1] containing one species, Parviraptor estesi, from the Late Jurassic (Tithonian) or Early Cretaceous (Berriasian) Purbeck Limestone Formation of Dorset, England.[1] A second species, Parviraptor gilmorei, was described from the Late Jurassic Morrison Formation of Western North America;[2] it was present in stratigraphic zone 4.[3] However, the second species was subsequently transferred to a separate genus Diablophis.[1]
