2.1" Fossil Ammonite (Leioceras) - Dorset, England

This is a 2.1" fossil ammonite (Leioceras) from Dorset England. This specimen has been opalized. The original organic material has been replaced with hydrated silica. It is in very good condition.

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.
