The study of fossils is called palaeontology. It is a widely distributed fossil, of the narrow range in time, regarded as characteristic of a given geological formation, used especially in determining the age of related formations." also the oldest fossil recorded in the Ordovician Period. Index fossils are the fossils that are commonly found as well as widely distributed and are the fossils limited in the period.

A thin, tubelike structure called a siphuncle pumped air through the interior chambers of the shell, which scientists believe helped provide buoyancy and move ammonites through the water. They are important aids to determine the correlation as well as the age of rock patterns. In juvenile forms are present constraints (bottlenecks) irregular along the spiral of the shell. During the Mesozoic era, they were common (245 to 65 million years ago ). Reference: Scientists have identified more than 10,000 species from fossils found nearly everywhere on the planet where oceans once existed, from the Great Plains of North America to the foothills of the Himalaya and the glaciers of Antarctica. t w%as foun(d in th)e jur%assi'c.

Nanofossils are very plentiful and it is distributed widely in the areas. Fossils are the remains of ancient living things like plants and animals preserved from the prehistoric period by the prospect of natural conditions. Both macrofossils (large fossils) and microfossils (miscroscopic fossils) are said to be used by geologists in Biostratigraphy. During their long history, ammonites survived three mass extinctionsmost notably the Permian extinction, a global warming that was brought on by volcanic activity about 252 million years ago, and that killed 96 percent of the planets marine species. This boom-and-bust character of fossils makes them a good fossil for geologists and palaeontologists.
