1 1/2" Polished Perisphinctes Ammonite Fossils - Madagascar
These are Upper Jurassic (160 million year old) ammonite fossils of the genus Perisphinctes collected near Sakaraha, Madagascar. They have been lightly polished to a glossy finish. The photos are representative of the ones you will receive though they are not the exact ones. They are approximately 1 1/2" to 1 3/4" wide.
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.
