Zoology: Bones

This juvenile chimpanzee skull is that of a male that is roughly between 6-1/2 to 9 years of age. The age of this individual was established by the eruption of teeth. Most of the permanent dentition, including maxillary and mandibular 2nd molars, is present and the 3rd molars are visible peeking through the alveolar bone. One maxillary canine is fully erupted while the other and both mandibular canines are still erupting. Age assessment based on dentition is approximate based on contrasting studies that typically have small sample sizes and different sample compositions (i.e. wild versus captive chimpanzees). The growth rates of wild versus captive chimps can vary widely. The origin of this individual is unknown. 2-part skull (separate cranium & jaw).
