7.2" Triassic Ammonite (Discoceratites dorsoplanus) Fossil - Germany

Triassic Ammonite (Discoceratites dorsoplanus) Fossil - Germany #243466

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.

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.
