Black, Cut & Polished, Ammonite Fossils - 1 1/2 to 2" Size

These are black ammonite fossils which have been cut in half and polished to reveal their detailed, inner chamber structure. The ammonites are Middle Cretaceous in age, or approximately 110 million years old and collected from the Mahajanga Province of Madagascar.

The dark, black/orange coloration is quite unusual as the majority of these ammonites are brown to yellow in color. The black ones have been collected from a different location and the difference in coloration would be due to changes to geological changes to the rock after fossilization occurred.

It's a real cool fossil that would make a great gift or could even be used to make jewelry. They range from 1 1/2 to 2" wide and both halves of the cut ammonite is included. The photos are representative of the ammonites you will receive, but don't picture the exact ones. Quantity discounts are available.

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.
