4.7" Iridescent Ammonite (Aconeceras) Fossil Cluster
This is a beautiful, 4.7" wide cluster of Aconeceras trautscholdi ammonite fossils from the Lower Cretaceous deposits of Saratov, Russia. They have been nicely exposed from the rock they were found in, revealing the stunning iridescent shell. One side of the rock has been cut flat, however the specimen 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.
