Abrictosaurus consors

When originally described as a species of Lycorhinus, the holotype fossil was thought to belong to a female because of the lack of tusk (thus the species name 'consors'). Richard Thulborn also thought that the animal had aestivation cycles. Hopson who did not believe in this theory renamed the genus Abrictosaurus (wakeful lizard).
