3.5" Jurassic Ammonite (Parkinsonia) Fossil - Sengenthal, Germany
This is a beautiful, 3.5" wide Parkinsonia ammonite from Sengenthal, Germany. This Jurassic-age ammonite has been carefully exposed from the rock it was found in, with a section of rock left in place on one side of the ammonite. Comes with an acrylic display stand.
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.
