4.4" Callovian Ammonite (Kosmoceras) Fossil in Rock - France

This is a fossil ammonite of the species Kosmoceras jason, collected from France. It is Callovian (Jurassic period) in age, or approximately 165 million years old. The majority of this ammonite has been exposed from the rock it was found in and comes with an acrylic display stand.

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. Ammonites appeared in the fossil record about 240 million years. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
