3.35" Jurassic Ammonite (Asteroceras) Fossil - Dorset, England
This is a beautifully preserved, 3.35" wide Asteroceras confusum ammonite fossil from the Lyme Regis region of England. One half of the ammonite has been prepped free from the rock. The base of the rock has been cut flat, creating an aesthetic display.
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.
