Ammonites are an extinct group of molluscs that are thought to be related to modern cephalopods such as octopus, squid and cuttlefish. They emerged during the early Devonian era (about 400 million years ago) and became extinct 65 million years ago at the end of the Cretaceous period. This Asteroceras obtusum fossil dates back to the Jurassic period (about 200-145 million years ago) and was found in Lyme Regis in Dorset, UK.
Note the second smaller Asteroceras that came to rest and fossilized in the living chamber of the larger Asteroceras.
