Deeply incised cut- marks can be seen around the edge of the articular surface. B, Three distal metapodials of Equus ferus, from left to right ventral view of M49834, dorsal views of M49977 & 49950. In each case, the shaft is split up to the articular surface with oblique fractures, curved, smooth, and shaft circumference 2. On M49834 there are cut-marks on the terminal end of the central ridge of the trochlea and a conchoidal scar on the dorsal side of the oblique fracture (not seen here); M49977 has percussion marks on the central ridge of the trochlea, visible here on the dorsal aspect as discolouration of the articular surface, conchoidal scars along the oblique break, and cut-marks on the shaft; M49950 also has cut-marks on the shaft along the ridge bordering the post-articular sulcus and conchoidal scars along the oblique break, and there are extensive percussion marks on the distal (terminal) part of the articular surface. These modifications appear to be concerned with breakage of the shaft for extraction of marrow and disarticulation of the foot. A, x ; B, attachment of the medial ligament of the hock joint. Cuts are therefore aimed at disarticulating the tarsal bones and tibia. Most of the marks were distributed in clusters of short incisions but no chops or percussion marks have been recorded. The lateral surface is smaller and has a wide rough fossa in which the lateral ligament is attached, and only isolated incisions have been found on the lateral trochlea. No human activity has been observed on these bones, so that there is no evidence of percussion or conchoidal scars. There is also no evidence of peeling, flakes removed or adhered flakes. Carnivore chewing marks are present on two specimens, one of them heavily chewed (M50003, lacking
