3.8" Jurassic Ammonite (Kosmoceras) Cluster - England

This is a 3.8" wide cluster of Kosmoceras (Guliemiceras) jasoni ammonites from Gloucestershire, England. The ammonites are nicely prepared and create a raw but aesthetic piece.

This specimen is accompanied by an acrylic 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.
