2.4" Ammonite (Physodoceras) Fossil - Drügendorf, Germany
This is a beautiful ammonite (Physodoceras sp.) fossil collected from the Drügendorf Quarry in Drügendorf, Germany. It's from the Upper Jurassic period. The surrounding rock has been removed to expose this 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.
