Scarce 3.3 Inch Desmoceras Ammonite
This is a much less often seen type of ammonite from Madagascar. It's Desmoceras which has a much wider, thicker body than the Cleoniceras ammonites.
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.
