What are the stages of taphonomy?
There are five main stages of taphonomy: disarticulation, dispersal, accumulation, fossilization, and mechanical alteration. The first stage, disarticulation, occurs as the organism decays and the bones are no longer held together by the flesh and tendons of the organism.
What are the 3 main categories of taphonomic processes?
Taphonomic processes include necrolysis (the break up of organisms after death), biostratinomy (the burial process itself), and diagensis (the post-burial transformation of the organic material).

What is an example of taphonomy?
This includes all the events that happen to an organism following death, its burial, and removal from the ground. Different examples of these processes include transport, surface weathering, and movement of elements by animals.
What can taphonomy tell us?
The Fossil Record
Sediments may tell us where it died, and taphonomy may tell us how and why it was preserved, but its teeth and bones can tell us how it lived – what it ate, how it moved, and possibly in what kind of social group it lived.
What is taphonomy in geology?
Abstract. Taphonomy is the study of how organic remains pass from the biosphere to the lithosphere, and this includes processes affecting remains from the time of death of an organism (or the discard of shed parts) through decomposition, burial, and preservation as mineralized fossils or other stable biomaterials.
What is taphonomy Why is it important to understand this process?
Taphonomy is important to paleoanthropology, a sub-field of biological anthropology, because it can reveal truths and negate notions regarding the natural and cultural processes after deposition, which in turn can inform us about the practices and environments of various hominins.
What are taphonomic changes?
Seven taphonomic changes were evaluated: the freeze-thaw cycle; rodent gnawing; carnivore scavenging; presence/weight of soil; presence/weight of rain and snow; movement/displacement of bones; and discoloration due to sun bleaching and grass staining.

Who created the idea of taphonomy?
The term is derived from the Greek words taphos, which means grave, and nomos, which means law. Russian scientist and science fiction writer Ivan Antonovich Efremov (1907–72) is often credited with first using the word and concept of taphonomy in 1940 within the established field of paleontology.
How are Permineralized fossils formed?
One of the common types of fossils is permineralization. This occurs when the pores of the plant materials, bones, and shells are impregnated by mineral matter from the ground, lakes, or ocean. In some cases, the wood fibers and cellulose dissolve and some minerals replace them.
