What is "zooarchaeology"

n. The study of animal remains at archaeological sites.

Zooarchaeology (or archaeozoology) 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.
