Like teeth, burned remains used to be overlooked in standard osteological studies. Today, more attention is given to burned remains both in regard to the process of thermally altering bones and the mortuary significance of cremation.
UIndy M.S. student studies of burned bones
Alexandria McDaniel, 2020 conducted experiments regarding low temperature thermal changes. Found that pig bone colors start to change around ~40 degrees C, and that heated but not yet burned bone has a mottled appearance
Elizabeth Oakley, 2015, studied thermal changes in people of Herculaneum. Found that some individuals reached at least 600 degrees C, although most people were shielded from the highest heat by a variety of factors.
Robin Quataert, 2018, studied Early Archaic (~10,000 y.b.p.) cremations from the Steele Site in southern Indiana. Found that several people were cremated ranging in age from new born to old adult (images above are faunal).
