9.6" Polished Ammonite Fossil - Suture Pattern Exposed
This is a large, 9.6" wide polished ammonite fossil from the Mahajanga Province of Madagagascar. The shell has been polished away revealing the unique, oak-leaf shaped suture pattern underneath.. 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.
