3.75" Polished, Agatized Ammonite (Cleoniceras) - Madagascar

This is a 3.75" wide polished ammonite (Cleoniceras) from Madagagascar. It displays the distinctive suture pattern of the Cleoniceras genus and would make a striking addition to any collection.

Includes 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.
