Cut and Polished Ammonite Fossil! 110 Million Years Old! Eagle Rock Rainbow ObsidianThis listing is for ONE random pull Cut and Polished Fossil Ammonite from the Mahajanga Province of Madagascar. These ammonites are approx 110 million years old, being from a formation that dates back to the Cretaceous period! 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.
