Osteology Osteology is the study of bones, of the skeleton. When we find skeleton fragments, we compare those fragments to the human skeleton, to evaluate the placement of the bone on an individual. By examining the muscle attachments, we can gauge the size of the individual.

Sexual dimorphism Humans are sexual dimorphic, which we can use to judge a skeletal fragment for its sex. Males are larger, with heavier muscles. The skull and pelvis are the best indicators of sex.

Determining Age Bones and teeth both give indicators of age at death. With bones, we measure the length of the long bones, while with teeth, we can gauge age by the date of eruption.

Dentition and food By examining the fossilized teeth of an individual, we can tell: Carnivore-all very sharp teeth Omnivore-many different shapes, for a variety of uses-heterodont The wear patterns also give us information on the types of food consumed.

Unformatted text preview: nutritional deficiency in prehistoric populations, usually through the skeletal remains. We can assess diseases such as arthritis, dental abscess, tumors, TB, leprosy, anemia, syphilis and a variety of infections. We also find evidence of cultural acts, such as trephination, a practice of cutting a hole in the skull of a living patient. Fossilized remains Taphonomy is the study of how organisms become part of the paleontological record. In other words, we look at the age, sex, and manner of death, but also the manner of preservation and fossilization. This helps us to explain how they got here, and also, how to find more. Evolutionary tree of the Primates Primates probably evolved between 90-60mya, definitely by 55 mya. Stereoscopic vision, and prehensile limbs were probably adapted to aid in hunting, but perfected in an arboreal environment....
