Front (manus) and rear (pes) footprints are distinguishable. The pes prints show five toes, with the fifth toe reduced to an oval pad. The manus prints likewise show five digits of similar length. Both kinds of prints show a fairly primitive anatomy, and the prints may have been produced by a rausuchid or other large thecodont (crocodile-like ancestors of reptiles).[6]
