12.5" Honey-Orange Ammonite (Argonauticeras) - Befandriana, Madagascar

This is not one of your typical Madagascar ammonites, it is a rare Argonauticeras from Befandriana in Northern Madagascar. The chambers are filled with a gorgeous, honey/orange colored agate. It's been sliced in half and polished to reveal the inner chamber detail.

Comes with a pair of display stands.

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.
