Observations: Here we present this unusual piece. This is the pedal ungual claw from some unidentified potential Thyreophoran ornithischian Dinosaur, from the Middle Jurassic of the Atlas Mountains. It has an unusual morphology. It is difficult to assign a specific taxonomic identification since very few of the dinosaurs from this Geological Formation have been formally described and not all the elements from the postcranial skeleton have been found with which to make comparisons. Anyway, this specimen is complete and only has one glued but not restored fracture.
