6" Wide Kosmoceras Ammonite Cluster - England

This is a 6" wide cluster of Kosmoceras (Guliemiceras) jasoni ammonites from Ashton Keynes, Gloucestershire, England. The block has been nicely prepared and the ammonites are nicely detailed. Comes with 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.
