added by archaeologs Fossilized or desiccated human or animal feces. The study of these remains can provide information about the human or animal activity in that particular locale, such as diet and disease; the study of these remains is called coprology. Coprolites only survive in exceptional circumstances - arid, frozen, and occasionally waterlogged deposits. They can be reconstituted by the addition of chemicals like trisodium phosphate, and can then be analyzed for their plant and animal remains. This gives additional insight into what was being eaten on a site, since the evidence from pollen analysis, or flotation, only suggests what was being grown.
