Peer Review #1 of "Hypercarnivorous teeth and healed injuries to Canis chihliensis from Early Pleistocene Nihewan beds, China, support social hunting for ancestral wolves (v0.1)"
Abstract:Collaborative hunting by complex social groups is a hallmark of large dogs (Mammalia: Carnivora: Canidae), whose teeth also tend to be hypercarnivorous, specialized toward increased cutting edges for meat consumption and robust p4-m1 complex for cracking bone.

Dated to the early Pleistocene (~1.2 Ma), Canis chihliensis from the Nihewan Basin of northern China is one of the earliest canines to… Show more
