Protochirotherium

Reptile footprint trace fossil

Protochirotherium, also known as Protocheirotherium, is a Late Permian?-Early Triassic ichnotaxon consisting of five-fingered (pentadactyl) footprints and whole tracks, discovered in Germany and later Morocco, Poland and possibly also Italy. The type ichnospecies is P. wolfhagenense, discovered by R. Kunz in 1999 alongside Chirotherium tracks, was named and described in 2004 and re-evaluated in 2007; a second ichnospecies, P. hauboldi, also exists, which was initially described as an ichnospecies of Brachychirotherium. Protochirotherium-like prints have also been documented from the Late Permian of Italy, possibly representing the oldest known fossils of mesaxonic archosauromorphs.
