1.7" Pyrite Replaced Ammonite (Peronoceras) Fossil - England

This is a beautiful ammonite of the species Peronoceras subarmatum. This well preserved ammonite is Jurassic in age and would have been found in a hard concretion that had to be split open. The hard rock then has to be removed mechanically to further expose the fossil.

There is a repaired crack through this ammonite. Comes with an acrylic 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. 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.
