Here is a gorgeous polished Cleoniceras ammonite fossil from the Cretaceous deposits of Madagascar. This exotic ammonite displays the spectacular "oak leaf" suture pattern of this species. It is large and very beautiful example of this 110 million year old fossil sea creature.

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.
