12.3" Wide, Polished Ammonite Fossil - Madagascar
This is a large, 12.3" wide polished ammonite fossil from the Mahajanga Province of Madagagascar. The intricate suture pattern that lies underneath the shell can be seen covering the specimen. This 110 million year old ammonite is truly a natural work of art and is very displayable on the included display stand.
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.
