Biostratinomy is the study of the processes that take place after an organism dies but before its final burial. It is considered to be a subsection of the science of taphonomy, along with necrology and diagenesis. These processes are largely destructive, and include physical, chemical and biological effects:Physical effects non-exhaustively include transport, breakage and exhumation. Chemical effects include early changes in mineralogy and oxidation. Biological effects include decay, scavenging, bioturbation, encrustation and boring.
