4.7" Jurassic Ammonite (Kosmoceras) Cluster - England

This is a 4.7" wide cluster of Kosmoceras (Guliemiceras) jasoni ammonites from Gloucestershire, England. The ammonites are nicely prepared and create a raw but aesthetic piece.

This specimen is accompanied by 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.
