2.2" Iridescent Ammonite (Quenstedticeras) Fossil With Pyrite
This is an absolutely gorgeous, Quenstedticeras ammonite fossil from the Saratov Region of Russia. These ammonites are Middle Jurassic (Upper Callovian Stage) or approximately 161-164 million years old. You can feel the weight during the internal pyritization of the fossil, and the shell has a beautiful iridescence to it.
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.
