Bulk: 1.5" Jurassic Cut/Polished Ammonites - 25 Pack

 
 
 
These are cut and polished orange ammonites collected near Sakaraha in the Tulear Province of Madagascar. Most of the cut and polished ammonites that you see from Madagascar are Cretaceous in age, but these ones with a orange/yellow/pink coloration are are Late Jurassic (Oxfordian Stage) in age.

You will receive twenty-five cut and polished ammonite fossil (both halves) chosen at random from our bulk bin. The photos are some representative examples of what they look like.

The previously hollow chambers of the ammonite were replaced with a beautiful agate during the fossilization process. Some of these chambers are still partially hollow and lines with druzy crystals. The ammonite was cut in half and polished revealing the inner chamber structure of this ancient, marine animal.

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.
