6.8" Golden Calcite Ammonite (Promicroceras) Cluster - England

Golden Calcite Ammonite (Promicroceras) Cluster - England #176344

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.

It comes with an acrylic display stand.

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
