Cut & Polished Desmoceras Ammonite (Half) - 3.7"

This is half of a beautiful, cut and polished ammonite of the genus Desmoceras from Madagascar. These ammonites are much thicker and heaver than the more commonly seen Cleoniceras ammonites. They are middle Cretaceous in age, approximately 110 million years old. Many of the chambers have been preserved as beautiful crystal lined pockets.

The ammonite comes with an acrylic display stand.

Ammonites were predatory mollusks that resembled squids with shells. These cephalopods had eyes, tentacles, and spiral shells. Though their shells resemble that of a nautilus, they are actually more closely related to living octopuses. Ammonites appeared in the fossil record about 240 million years ago, barely surviving several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
