36" Plate of Jurassic Ammonite Fossils - Posidonia Shale, Germany

This is a large 36" wide Harpoceras falcifer and Dactylioceras ammonite fossil association from the Posidonia Shale of Germany. Ammonites from this location have been compressed and are preserved on a black slate in a partially pyritized state.

The plate will be accompanied by a metal 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.
