The Lealt Shale Formation is a Middle Jurassic geologic formation in Scotland. Fossil ornithopod , theropod and stegosaur tracks, a theropod dinosaur tooth and the pterosaur Dearc have been reported from the formation.[1][2][3] The lithology consists of silty fissile mudstones with subordinate thin limestones.[4]
