Absolutely Stunning 5.2 Inch Ammonite (Half)
This is half of a cut and polished 110 million year old ammonite fossil from Madagascar. It is 5.2 inches wide and exhibits absolutely stunning crystal lined cavities. The reverse side of it has a beatiful, mother of perl colored shell. This fossil looks just like a work of art.
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. Ammonites appeared in the fossil record about 240 million years ago and they barely survived several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
