Fossiloitumistapojad, or fossilization processes, are the mechanisms by which organic remains are transformed into fossils over time. This process typically occurs in several stages, beginning with the death of an organism and ending with the preservation of its remains in the geological record. The first stage involves the rapid burial of the organism to prevent decomposition by scavengers and bacteria. This is often facilitated by sediment deposition, such as in riverbeds, lakes, or marine environments.

Once buried, the organic material undergoes diagenesis, a process that includes the replacement of original organic compounds with minerals. This replacement can occur through several mechanisms, including permineralization, where minerals fill the pores of the organic material, or replacement, where minerals gradually replace the original organic compounds. The type of minerals involved can vary, but common examples include silica, calcite, and pyrite.

The preservation of soft tissues, such as skin, muscles, and internal organs, is relatively rare and often requires exceptional conditions, such as rapid burial in anoxic (oxygen-free) environments. In contrast, hard tissues like bones and shells are more commonly preserved due to their mineral composition.

The fossilization process is influenced by various factors, including the type of organism, the environment of deposition, and the duration of burial. The resulting fossils can provide valuable insights into past ecosystems, evolutionary history, and environmental conditions. They are typically studied by paleontologists to understand the history of life on Earth.
