Feralisaurus is an extinct genus of neodiapsid reptile, possibly a basal lepidosauromorph, known from the Middle Triassic of south-western England. It contains one species, Feralisaurus corami, which was described by Cavicchini et al. in 2020.[1] It was found in the Helsby Sandstone Formation.
The holotype and only known specimen of Feralisaurus, BRSUG 29950-12, was discovered in 2014 near Sidmouth, Devon.[1]
Feralisaurus was recovered as either a basal neodiapsid or as a basal lepidosauromorph, with the researchers preferring a placement within Lepidosauromorpha.[1]
