7.5" Jurassic Fossil Ammonite (Parkinsonia) Cluster - Germany

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 mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
