11.7" 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.

About four years ago I was able to acquire three of gorgeous ammonites of this genus and had not seen them on the market since. The story is the area these are collected in is very remote and dangerous and the person who had been digging them passed away. I was able to acquire several large pairs of these recently, but I expect they will sell very quickly and who knows if we will ever be able to get anymore.

Comes with a pair of display stands.

Each half of the ammonite differs in size slightly, with one half measuring 11.7" wide, while the other is 11.6" wide.



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.
