5.3" Jurassic Ammonite (Parkinsonia) Fossil - France

Jurassic Ammonite (Parkinsonia) Fossil - France #244478

This is a very beautiful, 5.3" wide Parkinsonia ammonite from Fresney, France. This Jurassic-aged ammonite is still partially embedded in the rock it was found in. The base of the rock has been cut flat so that it stands on its own accord.

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.
