5.8" Fossil Ammonite (Psiloceras) Cluster - Holderness Coast, England

This is a 5.8" wide cluster of Lower Jurassic Psiloceras ammonites from the Holderness Coast in East Yorkshire England.

There are over twenty ammonites ranging from .4 to 1.75 inches across preserved within a concretion. It was painstakingly prepared with mechanical tools to expose all of the ammonites in high relief.

This piece comes out of the collection of the late Jeff Mulroy, a renown collector and preparitor of Yorkshire fossils.

Comes with a 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. 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.
