14" Ammonite (Paracoroniceras) Fossil - Dorset, England

This is a breathtaking specimen of the Lower Jurassic ammonite Paracoroniceras lyra, collected from Lyme Regis region of England. It's 14" wide and was originally found inside of a concretion that was almost completely prepped away. The display side of the ammonite has had the rock carefully removed and lightly polished while the reverse side still shows the surrounding concretion.

Comes with a metal display stand.

The center of the ammonite has been restored, as this area is frequently not well preserved on larger ammonites. There is some additional touchup restoration along the periphery of the ammonite.

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.
