Ammonites are an extinct group of marine Molluscs of the class Cephalopoda. Their widely-known fossils show a ribbed spiral-form shell, in the end compartment of which lived the tentacled animal. These creatures lived in the seas from at least 400 to 65 million years ago. These molluscs are closely related to octopuses, squid, and cuttlefish. Ammonites varied in size from centimeters to 2 meters (Parapuzosia seppenradensis) in diameter.
