12.1" Choffaticeras ("Daisy Flower") Ammonite Half - Madagascar

This is a stunning, 12.1" wide example of a rarely seen ammonite (Choffaticeras) from Madagascar. Ammonites of this genus are often referred to as Margarite or "Daisy" flower ammonites. It has been cut in half and polished to reveal the amazing inner detail.

This specimen has undergone little to no repair work and is not a composite. Includes a 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. 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.
