11.6" Daisy Flower Ammonite (Choffaticeras) - Madagascar

This is a large, 11.6" wide example of a rarely seen ammonite (Choffaticeras sp.) 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. Some of the chambers have been preserved as deep, spectacular calcite crystal encrusted pockets. This is an extremely aesthetic and displayable ammonite fossil.

This specimen has some repairs which is nearly all large ammonites do as they are fractured while in the ground. This listing includes both halves of the ammonite plus 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.
