The Fabrosauridae was originally proposed by Galton (1972), as a group of basal ornithischian dinosaurs from the Early to Middle Jurassic. However, recent studies indicate the Fabrosaurs are not a natural grouping of dinosaurs, and instead consist of unrelated genera. The proposed "Fabrosaurs" descended from a Lesothosaurus-like animal. Proposed fabrosaurids were 1-2 meters long, and were lightly-built and bipedal. Their skulls were triangular and had very large eye sockets. They were herbivorous and would have used agility to escape predators.
