There have been lots of movements in the earth's crust with upthrusts, down thrusts, plates shifting, etc. As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. Timeline of paleontology Gathering fossils dates at least to the beginning of recorded history. Once deposited, physical and chemical weathering can alter the state of preservation. Cyanobacteria use water , carbon dioxide and sunlight to create their food. Inclusions of igneous rocks[ edit ] Multiple melt inclusions in an olivine crystal. Since animal species change over time, the fauna can be arranged from younger to older. Leaves , stems , and other vegetable matter may be preserved through the process of carbonization, where such parts are flattened between two layers of rock. For example, the principle of superposition is based, fundamentally, on gravity. Sedimentary rock is laid down in layers caused by wind, erosion, rain and bodies of water moving particles of minerals and depositing them one after another in what becomes large sheets of deposits. The oldest fossil resin dates to the Triassic , though most dates to the Cenozoic.
