• Mineralization: This fossilization process occurs when an organism's remains are buried and replaced by minerals from groundwater, hardening into a rock-like structure; petrified wood serves as a prime example. • Carbonization: Over time, compression of deceased organisms leaves behind a carbon film outlining the original organism's shape. • Molds, Casts, and Trace Fossils: Molds are impressions left by organisms in sediment, which can later be filled to create a cast. Trace fossils represent preserved evidence of organism behavior, such as footprints or burrows.
