Black, Cut & Polished, Ammonite Fossils - 1 1/4 to 1 1/2" 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 were collected from the Mahajanga Province of Madagascar.

The dark black and 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 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 1/4 to 1 1/2" wide and both halves of the cut ammonite are included. The photos are representative of the ammonite(s) you will receive, but don't picture the exact ones.

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
