What is a Fossil? Fossils are the remains of organisms or other signs (i.e. tracks) of organisms that lived in the past. For example bones, or shells. Ichnofossils (trace fossils) are for example tracks, bitemarks, and excretions. These ichnofossils can teach us a lot about the organism. Fossils are often petrified. This takes place as a result of chemical mineralisation processes. Paleontology Geology is the science of the earths crust, and the processes within. Geology comprises topics like earthquakes, volcanoes, oil and gas exploration, minerals, and fossils. The specialistic science of fossils is called Paleontology. The best-preserved fossils form when the organism is quickly buried. If the organism is not buried quickly, external factors such as scavengers, decay and the weather can deteriorate the quality of the fossil to be. The right conditions for fossilization are exceptional. In most cases an organism will not fossilize. If the organism is buried in an anoxic environment, even the soft parts
