Lot: 3 1/2 - 4" Cut Ammonite Pairs (Grade C) - 10 Pairs

This is a wholesale lot of cut and polished Cleoniceras ammonite fossils from the Mahajanga Province of Madagascar. They are Early Cretaceous (Albian Stage) in age, or approximately 110 million years old.

The lot includes 10 ammonites with both halves included. They range from 3.4 to 4.2" wide and the entire lot weighs about 4 1/2 lbs. They are grade C specimens meaning many of the chambers visible in the interior's of the ammonite are not well defined or had been filled with mud prior to fossilization. The exterior of the ammonites are attractive with a mix of some showing iridescent shell preservation and others polished to show the "oak leaf" suture pattern underneath the shell.

At the wholesale price each ammonite (both halves) is $7.50 each and they can easily retail for several times that amount.

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.
