Ammonite Association on Stand

Madagascar A variety of Ammonite fossils found together have been polished to shine bright and show off the intricate suture patterns on their shells, as well as a little iridescence at the center of the base Ammonite.  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.
