13.7" Orange, Crystal Filled, Cut Ammonite Fossil (Pair) - Jurassic

 
 
 
 
This is a large, 13.7" wide, cut and polished ammonite fossil collected in the Tulear Province of Madagascar. Most of the cut and polished ammonites that you see from Madagascar are Cretaceous in age, but these with orange/yellow/pink coloration are are Late Jurassic (Oxfordian Stage) in age, nearly 50 million years older.

The previously hollow chambers of the ammonite became filled with crystals after the ammonite fossilized creating almost a geode like structure. The ammonite has been cut in half and polished to reveal these crystal filled chambers. The back side of the ammonite has been stabilized with epoxy.

It comes with a pair of metal display stands.

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. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
