7.8" Agatized, Cut & Polished Ammonite Fossil - Madagasar

This is a 7.8" wide cut and polished ammonite (Cleoniceras) fossil from Madagascar. It exhibits gorgeous mineralization within the chambers, each separated by white calcite septa (divisions). Some of the chambers are still hollow and lined with druzy quartz crystals.

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.
