4.3" Bumpy Ammonite (Douvilleiceras) Fossil - Madagascar
This is a nice Douvilleiceras ammonite from the Upper Cretaceous, collected in Madagascar. This genus of ammonites has a distinctively bumpy surface and pronounced ridges, resembling a tractor tire; hence their nickname as "Tractor Ammonites".

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
