11.6" Ammonite (Promicroceras & Cymbites) Cluster - England

Ammonite (Promicroceras & Cymbites) Cluster - England #279475

This is a 11.6" wide concretion filled with small, golden calcite replaced fossil ammonites of the species/genus Promicroceras praecompressum and Cymbites. It was collected from Monmouth Beach near the town of Charmouth, England. This type of ammonite specimen is commonly referred to as "popcorn stone". 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.
