5.6" Toarcian Ammonite (Hammatoceras) Fossil - France

This is a fossil ammonite of the genus Hammatoceras that was collected near Belmont, France. It is Toarcian (Jurassic period) in age, or approximately 180 million years old. It has been partially exposed from the rock it was found in, with one edge cut flat for presentation purposes.

Ammonites were predatory mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
