6.2" Triassic Ammonite (Ceratites nodosus) Fossil - Germany

This is a 6.2" wide specimen of a Middle Triassic ammonite (Ceratites nodosus). It comes from the the Muschelkalk Formation in Germany. It was found inside of a hard concretion which has been almost entirely removed from the ammonite. It comes with an acrylic display stand.

There are spots of gap fill restoration along the edge where the shell broke away during collection. The center spiral of the ammonite has also been restored.

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
