With squidlike tentacles extending from their distinctive multichambered shells, the extinct marine predators known as ammonites were once among the most successful and diverse animals on Earth. It is split into Quaternary Period, Pecten gibbus, and Tertiary Period, Calyptraphorus velatus. These cephalopods make for ideal index fossils because they are abundant, widespread, and their various species lived during distinct time periods that can be easily identified by their suture patterns. Some scientists hypothesize that the ammonites couldnt survive the aftermath because of the sudden decline of their main food source: marine plankton. Details. Ammonites make excellent guide fossils for stratigraphy because: The rapidity of ammonite evolution is the single most important reason for their superiority over other fossils for the purposes ofcorrelation. Graptolites: They are thin and shiny. Their fossils have been commonly discovered dispersed throughout Europe. The terrestrial parts also have such rocks that consist of index fossil fuels.

J. Bowen (18981980). The fossils of the organisms are moved to the upper layers of the ocean where the rocks contain these fossils. This boom-and-bust character of fossils makes them a good fossil for geologists and palaeontologists. Perisphinctes is an extinct genus of ammonite cephalopodthat lived during the Jurassic period and serve as an index fossil for that time period. While many species of ammonites died out in that extinction event, scientists believe the survivors diversified explosively in the million years that followed.

The Perisphinctes boweni ammonite was named after the English chemist and geologist E. J. Bowen (1898-1980). The many chambers of their shells likely helped these cephalopods glide through the planets warm, shallow seas. The ammonites became extinct at the end of the Cretaceous, at roughly the same time as the dinosaurs disappeared. (Perisphinctoidea in references) When the date of the rocks is determined using index fossils, these rocks can be further studied to help find the period when the fossils were created. Few definitions of index fossils are mentioned below: "It is a fossil usually with a narrow time range and wide spatial distribution that is used in the identification of related geologic formations."
