1.8" Jurassic Ammonite (Xipheroceras) Fossil - Dorset, England
This is a beautiful, 1.8" wide ammonite (Xipheroceras drudrieseri) fossil from the Lyme Regis region of England. It has been beautifully prepared from the hard limestone to expose one side of the ammonite. The base of the rock has been cut flat for presentation.
Ammonites were predatory mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
