Lealt Shale

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