3.2.2.2.2 Human Versus Non-Human Biological Material: Human osseous and dental remains can be distinguished from non-human biological material on the basis of developmental morphology, which is often best illustrated by comparison with known human and non-human exemplars. Common non-human materials confused with human remains include suids, canids, ursids, and bovids. Human osseous remains exhibit articular surfaces and bony landmarks unique to the species. Similarly, human dental remains exhibit features unique to humans.
