Final answer:
Taphonomy is the branch of paleontology that studies the process of fossilization and the factors that influence the preservation of organic remains.
Step-by-step explanation:
The study of the fossilization process itself is called taphonomy. Taphonomy is a branch of paleontology that focuses on how organisms decompose and become fossilized, including the processes that contribute to the preservation — or lack thereof — of their remains. Fossils can be preserved via unaltered soft or hard parts, altered hard parts, and trace fossils, with each method offering insights into ancient life and environmental conditions.
