Jurassic Ammonite, Bivalve, Gastropod & Belemnite Association - France

Here is a beautiful association of Middle Jurassic marine fossils, collected from Fresney, France. There is a 4.4" wide Leioceras ammonite that's next to a partial belemnite and bivalve fossils. Two Stephanoceras ammonites and another, smaller Leioceras ammonite are also featured on this specimen. The piece has been wonderfully prepared to create this aesthetic display.

There is some glue stabilization near the largest ammonite and the largest belemnite.

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.
