7.5" Jurassic Fossil Ammonite (Parkinsonia) Cluster - Germany

Jurassic Fossil Ammonite (Parkinsonia) Cluster - Germany #244480

This is a gorgeous, 7.5" wide Parkinsonia ammonite cluster from Sengenthal, Germany. These Jurassic-aged ammonites have been carefully exposed from the rock, with a section of rock still attached for presentation. A small bivalve fossil can be found just above the smaller ammonite.

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.
