7.2" Triassic Ammonite (Discoceratites dorsoplanus) Fossil - Germany

This is a 7.2" wide specimen of a Middle Triassic ammonite (Ceratites (Discoceratites) dorsoplanus). It comes from the the Muschelkalk Formation in Germany. It was found inside of a hard concretion and has been nicely prepared with all of the surrounding rock removed.

There are small spots of gap fill restoration along the thinnest edge where the ridge intersects with the "opening". Some restoration can also be found within the center spiral.

It comes with 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.
