6" Jurassic Ammonite (Euhoploceras) Fossil - Dorset, England

This is a 6" wide, polished ammonite (Euhoploceras modestum) fossil from Dorset, England. It is Lower Jurassic in age, or approximately 160 million years old. It is prepped completely free of the rock it was found in and comes with a 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.
