Zooarchaeology
Zooarchaeology (or archaeozoologist) is the study of faunal remains. Faunal remains are the items left behind when an animal dies. It includes: bones, shells, hair, chitin, scales, hides, proteins and DNA. Of these items, bones and shells are the ones that occur most frequently at archaeological sites where faunal remains can be found. Much of the time, most of the faunal remains do not survive. They often decompose or break because of various circumstances. This can cause difficulties in identifying the remains and interpreting their significance.
Development
The development of zooarchaeology in Eastern North America can be broken up into three different periods. The first being the Formative period starting around the 1860s, the second being the Systematization period beginning in the early 1950s, and the Integration period which began about 1969.
Full-time zooarchaeologists didn’t come about until the Systematization period. Before that it was just a technique that was applied but not specifically studied.
