Evolution lab fossil type definitions:
Mold: Fossils formed when the sediment surrounding a buried organism hardens. When the organism decays, its impression is left in the rock and can be seen if the rock is broken open.
Cast: Fossils formed when water containing minerals leaks into a mold. The minerals harden to form a copy of the original structure or organism.
Mineralization: The process of replacing any organism’s original material with a mineral.
Impression: Prints or marks made when an organism’s body has been compressed (flattened). Impressions are different from compressions because no thin organic material is left behind.
Preserved as they are: Living things that are preserved in their whole state without being decomposed. These are rare, as most fossils are either consumed or decay upon death. See this website for examples of ways in which fossils are preserved without being buried.
