6.1" Polished Ammonite (Puzosia) Fossil - Madagascar

This is a 6.1" wide polished ammonite from Madagascar of the genus Puzosia. It is absolutely gorgeous, with portions of the specimen displaying the distinctive "oak-leaf" suture pattern along the polished surface. This 110 million year old ammonite is truly a natural work of art and is very displayable on the included acrylic stand. The sutures on it have been meticulously exposed and cleaned making the ammonite look that much nicer.

Ammonites were predatory mollusks that resembled squids with shells. These cephalopods had eyes, tentacles, and spiral shells. Though their shells resemble that of a nautilus, they are actually more closely related to living octopuses. Ammonites appeared in the fossil record about 240 million years ago, barely surviving several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
