Two Jurassic Ammonite (Parkinsonia) Fossils - France
This is a very beautiful association of Parkinsonia ammonites from Fresney, France. These Jurassic-aged ammonites are still partially embedded in the rock they were found in and are naturally associated with two belemnite fossils and an additional partial ammonite fossil. The base of the rock has been cut flat for presentation purposes.
The specimen weighs just over 10 lbs, measures 8.7 x 8 x 5.2", and the largest ammonite is 5.3" wide.

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.
