7 Small Ammonite Halves - Mismatched Pairs
Here is a selection of 7 small mismatched halves from cut and polished Madagascar ammonites. They range from approximately .9 to 1.2 inches and would be great for jewelry making.
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.
