4" Phylloceras Ammonite Fossil - England

This is a thick, 4" wide Phylloceras ammonite collected in North Yorkshire, England. This particular specimen has a partially pyritized shell.


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.
