7.25" Polished Cretaceous Ammonite (Cleoniceras) Fossil - Madagascar

This is a polished ammonite fossil from the species, Cleoniceras sp. It was collected from the Cretaceous Mahajanga Province of Madagascar where many ammonite fossils on the market today are found. It has limited iridescence but will exhibit a small red flash when placed at certain angles to the light.

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. Ammonites appeared in the fossil record about 240 million years ago and they barely survived several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
