1.5" Bathonian Ammonite Fossil - France
This is a 1.5" wide fossil ammonite that was collected from St. Benin, France. It is Bathonian (Jurassic period) in age, or approximately 168 million years old.
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.
