Curious Minds Did You Know? The study of fossils is called Palaeontology.
Ammonites are an extinct group of marine predators that ruled the Oceans for 370 million years before mysteriously becoming extinct at the end of the cretaceous period. Scientists have identified more than 10,000 species from fossils all over the planet from the Great Plains of North America to the glaciers of Antarctica.
Most species of Ammonites had coiled shells lined with progressively larger chambers and had squidlike tentacles attached to their heads for catching prey. A type of mollusc, they are related to other cephalopods like Squid, Octopuses and Cuttlefish.
