In addition, the manner in which the egg had been crushed and fragmented indicated that it had been intact at the time of burial, and was broken by the fossilization process.

The spores showed considerable damage from both the fossilization process and the subsequent weathering and specimen collection.

The fossilization process replaced the wood with limonite and hematite.

Subfossils refer to remains, such as bones, nests, or defecations, whose fossilization process is not complete, either for lack of time or because the conditions in which they were buried were not optimal for fossilization.

Deformation of the skull through natural fossilization processes has changed the shape slightly, making it asymmetrical, but overall it remains an excellent specimen for studying the cranial morphology of this particular genus and species.

It used to be thought that they had webbed hands, but this was an artifact of the fossilization process.

In the fossilization process, minerals replace the constituents of bones, turning them to stone.

The products of the volcanic activity covered the vegetation of the area and the fossilization process took place during favourable conditions.

Often much of this information is lost or distorted by the fossilization process or diagenesis of the enclosing sediments, making interpretation difficult.

The majority of ammonoid specimens, especially those of the Paleozoic era, are preserved only as internal molds; the outer shell (composed of aragonite) has been lost during the fossilization process.
