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.

About Ammonites
Ammonites were ancient marine cephalopods, similar to today's squids and octopuses, but with a defining feature: their distinctive, tightly coiled spiral shells. These shells, resembling those of modern nautiluses, served as both a protective home and a buoyancy aid, allowing ammonites to navigate the prehistoric seas with ease. First emerging around 240 million years ago in the Triassic Period, ammonites thrived for over 175 million years, adapting through numerous forms and sizes. As predatory creatures, they likely fed on smaller marine organisms, using their tentacles to capture prey. However, their long reign came to an end 65 million years ago at the close of the Cretaceous, coinciding with the mass extinction event that also eliminated the dinosaurs.
