Tepexpan Man has a healed fracture on his right ulna. De Terra thought that due to this fracture and the proximity to mammoth fossils, Tepexpan Man may have been a hunter who was either killed by his fellow men or mortally wounded while hunting. The Science Newsletter claims that the individual suffered from a stiff neck due to the many limy deposits on the cervical vertebrae. This means that Tepexpan Man most likely suffered from arthritis.
