5.4" Pyritized Ammonite (Quenstedticeras) Fossil Composite Cluster
This is an interesting and colorful pyritized ammonite (mostly Quenstedticeras sp.) cluster. The ammonites were collected from the Middle Jurassic aged deposits in Moscow Basin, Russia. The cluster is not natural in the sense that the ammonite fossils have been attached together with pyrite and glue.
The entire specimen is 5.4" wide and is accompanied by an acrylic display stand.

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.
