2.3" Fossil Pyritized Ammonite (Hildoceras)- England

This is a 2.3" pyritized ammonite (Hildoceras), from Whitby, England. The original organic material has been replaced by pyrite. Under magnification the elaborate suture pattern of the inner shell is easily seen.

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. Ammonites appeared in the fossil record about 240 million years ago and they barely survived several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
