Sedimentary rock often contains fossils because it is formed differently. It consists of sandstone, limestone, or shale that was once mud or sand in which the bodies of dead animals settled. The temperatures and pressures that create sedimentary rock are much lower and don’t destroy fossil remains. For fossils to form, the parts of a dead ...
Limestone ( calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium.The rapidity of ammonite evolution is the single most important reason for their superiority over other fossils for the purposes of correlation. Such correlation can be on a worldwide scale. Ammonites can be used to distinguish intervals of geological time of less than 200 000 years' duration.
