This is a thick, 4.5" wide Phylloceras ammonite collected in the Mahajanga Province of Madagascar. The exterior has been highly polished and you can see the beautiful suture patterns just beneath the translucent shell. An absolutely gorgeous specimen, of a type not as frequently seen for sale.

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
