4.6" Jurassic Ammonite (Parkinsonia) Fossil With Belemnite - England

Jurassic Ammonite (Parkinsonia) Fossil With Belemnite - England #240842

This is a gorgeous, 4.6" wide example of Parkinsonia rarecosta, a species of ammonite from the Inferior Oolite of Dorset, England. It is Jurassic in age and has been meticulously exposed from the rock it was found in. A belemnite fossil has also been exposed, resulting in this natural fossil association. The base of the rock has been cut flat for presentation.

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
