3.1" Triassic Ammonite (Ceratites posseckeri) Fossil - Germany
This is a 3.1" wide specimen of a Middle Triassic ammonite (Ceratites posseckeri). It comes from the the Muschelkalk Formation in Germany. It was found inside of a hard concretion and has been nicely prepared with a portion of rock remaining, acting as a display base.
There is a repaired crack through the ammonite where the nodule split. Small spots of gap fill restoration can be found towards the central spiral of the ammonite.

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.
