5.1" Fossil Ammonite (Cleviceras) Cluster - Sandsend, England
This is a 5.1" tall cluster of ammonites (Cleviceras elegans) from the Sandsend, England. The base of the rock has been cut flat allowing it to display nicely on a flat surface without a 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.
