A genus of primitive ornithischian dinosaurs of the early Jurassic, which were small and lightly built; (also fabrosaurus) a dinosaur of this genus.
This genus is now regarded as dubious: the minimal remains may actually belong to the similar genus Lesothosaurus.
1970s. From scientific Latin Fabrosaurus, genus name from the name of Jean Fabre (b. 1920), French geologist + -o + -saurus.
