6.8" Golden Calcite Ammonite (Promicroceras) Cluster - England

 
 
 
This is a 6.8" wide concretion filled with small, golden calcite replaced fossil ammonites of the species Promicroceras planicosta. It was collected from the Black Ven cliff near the town of Charmouth, England. The concretion was painstakingly prepared using mechanical tools to expose the ammonite fossil and bring them out in high relief.

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.
