Fossils are preserved through various processes, primarily when organisms are buried quickly after death, protecting them from decay and scavengers. The most common methods of fossilization include permineralization, where minerals infiltrate and replace organic material, and cast and mold formation, where sediment fills in the shape of the organism. Other preservation methods include amber encasement and freezing in ice. Over time, geological processes can further solidify and expose these fossils for study.

Preserved remains of a living thing are called fossils. Fossils can be bones, shells, imprints, or traces of ancient organisms that have been preserved in rocks. They provide valuable information about past life forms and environments.
The fossil that is not preserved and starts with a D is a "dinosaur." Fossils are the preserved remains or traces of ancient organisms, but dinosaurs themselves are not preserved as fossils. Dinosaurs were a diverse group of reptiles that lived millions of years ago, and their fossils provide valuable insights into the Earth's history and the evolution of life on our planet.
Cast fossils: Formed when minerals fill a mold left by a decayed organism. Mold fossils: Created when an organism's remains leave an impression in sediment that hardens into rock. Petrified fossils: Organic material replaced by minerals over time, forming a rock-like replica. Trace fossils: Evidence of an organism's activity (e.g., footprints or burrows) preserved in sedimentary rock. Carbon fossils: Organisms preserved in carbon-rich environments, like coal or oil deposits. Preserved fossils: Organisms remain intact or partially intact due to exceptional preservation conditions.
