6.1" Polished Ammonite (Cleoniceras) Fossil - Madagascar

This is a beautiful, 6.1" wide, polished ammonite (Cleoniceras sp.) fossil from Madagascar. It displays a distinctive, "oak-leaf" suture pattern on the surface. These ammonites are collected near Ambatolafia in the Mahajanga Province of Madagascar.

Comes with an acrylic display stand.

Ammonites were predatory mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
