4.5" Ammonite (Aegasteroceras) Fossil - England

 
 
This is an absolutely beautiful ammonite fossil from the Conesby Quarry near Scunthorpe in North Lincolnshire, England. It's Lower Jurassic in age, or approximately 200 million years old. The ammonite is of the species Aegasteroceras sagittarium, has some slightly green coloration and measures 4.5" wide. The base of the rock has been cut flat for aesthetic presentation of the ammonite without the need for a display stand.

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. Ammonites appeared in the fossil record about 240 million years. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
