This polished ammonite displays distinctive ridging and oak leaf suture patterns detailed on the outer shell.
Ammonites are cephalopods that had eyes, tentacles, and spiral shells. They are more closely related to a living octopus species even though they resemble that of a nautilus because of the spiral shell. Ammonites appeared in the fossil record approximately 240 million years ago. The last ammonite fossils disappeared about 65 million years ago at the end of the Cretaceous.
This chambered ammonite measures 6" in diameter.
