taphonomy

This term is a specialized scientific designation used primarily in paleontology, archaeology, and forensic science. It describes the transition of organic remains from the biosphere to the lithosphere, focusing on the chemical and physical alterations that occur between death and discovery.

Because it refers to a specific academic discipline or a set of biological processes, it is treated as an uncountable noun. It is rarely used in casual conversation and is almost exclusively found in technical reports, peer-reviewed journals, or academic textbooks.
