Chirotherium, also known as Cheirotherium (‘hand-beast’)...
wikipedia - 10 Jul 2015Chirotherium, also known as Cheirotherium (‘hand-beast’), is the name of a Triassic trace fossil consisting of five-fingered (pentadactyle) footprints and whole tracks. These look, by coincidence, remarkably like the hands of apes, humans, and bears, with the outermost toe having evolved to extend out to the side like a thumb, although probably only functioning to provide a firmer grip in mud. Chirotherium tracks were first found in 1834 in Lower Triassic sandstone (Buntsandstein) in Thuringia
