Both macrofossils (large fossils) and microfossils (miscroscopic fossils) are said to be used by geologists in Biostratigraphy. He found that fossil remains, as well as the structure of the rocks around the coastlines of South America, Africa and India, were similar to each other despite being separated by oceans such as the Atlantic and the Indian Ocean. This ammonite was a form cosmopolitan, widespread in warm-temperate waters worldwide. Ammonites began life as tiny planktonic creatures less than 1mm in diameter. Million Years Ago. It is divided into Cretaceous Period, Scaphites hippocrepis, Jurassic Period, Perisphinctes tiziani, and Triassic Period, Trophites subbullatus. There are mainly 4 characteristics of these fuels. they evolved rapidly so that each ammonite species has a relatively short life span they are found in many types of marine sedimentary rocks they are relatively common and reasonably easy to identify they have a worldwide geographical distribution If complete, this specimen would have had a diameter of about 2.55 m. The most important functions of the ammonite shell were protection and flotation. While many species of ammonites died out in that extinction event, scientists believe the survivors diversified explosively in the million years that followed. Quaternary Period. What is a fossil and why do we study them? they evolved rapidly so that each ammonite species has a relatively short life span, they are found in many types of marinesedimentary rocks, they are relatively common and reasonably easy to identify, they have a worldwide geographical distribution. Another term, Zone fossil is used when the fossil have all the characters stated above except wide geographical distribution, they are limited to a zone and can't be used for correlations of strata. The use of ammonites instratigraphywas pioneered in the 1850s by two Germans Friedrich Quenstedt of Tbingen (18091889) and his one-time pupil, Albert Oppel of Munich (18311865).
