3.5" Jurassic Ammonite (Parkinsonia) Fossil - France

Jurassic Ammonite (Parkinsonia) Fossil - France #301626

This is a very beautiful Parkinsonia ammonite fossil from a Middle Jurassic (Bajocian Stage) deposit in Fresney, France. It's still partially embedded in the rock it was found in. The base of the rock has been cut flat for presentation purposes.

There is a repaired crack through the ammonite and spots of gap fill restoration where pieces flaked away during collection.

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.
