Ammonoidea includes a more exclusive group called Ammonitida, also known as the true ammonites. These animals are known from the Jurassic Period, from about 200 million years ago. Most ammonites died out at the same time as the ...

Ammonite Zones: Ammonites have played a significant role in the development of biostratigraphy, which is the subdivision of geological time based on fossil assemblages. By studying the distribution of ammonites in rocks, paleontologists have established a zonal scheme known as the Ammonite Zone System.Ammonites are younger than trilobites. Trilobites are thought to have originated roughly 540 million years ago. Ammonites first appeared about 450 million years ago. So ammonites are about 100 million years younger. This is reasonable, because ammonites have a slightly more complete anatomy, so they took longer to evolve.Ammonite is actually the colloquial term for ammonoids, a large and diverse group of creatures that arose during the Devonian period, which began about 416 million years ago.

As a result, ammonoids have indeed been called the Drosophila of evolutionary studies because of the range of evolutionary problems to which they ...
