Having to do with taphonomy, the processes and conditions under which organisms become fossilized.
It can also mean having to do with the study of the same.
A 'taphonomic analysis' is when you look at fossils to try and figure out what happened when the being died, both to cause the death and to make it fossilize afterwards.
Pronounced tuh-fon-uh-mik. From the Greek táph, meaning 'burial' or 'grave', plus -onomic. The root word 'taphonomy' was coined in the late 1960s, based on the model of anthropology and paleontology.
