The Fabrosauridae is an obsolete group of basal ornithischian dinosaurs from the Early to Middle Jurassic, originally proposed by Galton (1972). 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.
