Very Rare Black Agatized, Cut & Polished Ammonite Fossil from Madagascar


This cut and polished ammonite (Cleoniceras) fossil from Madagascar is 90mm wide x 111mm high and weights 317 gram. It exhibits gorgeous mineralization within the chambers, each separated by white calcite divisions. Some of the chambers are still hollow and lined with druzy crystals.

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.
