These beautiful, split Perisphinctes Ammonites were discovered in the Tulear Region of Madagascar. They date from the Mesazoic Era, Upper Jurassic Series, Oxfordian Epoch, and are between 161m to 155m years old.

They were marine creatures related to today's Nautiloids, and swam using air for buoyancy in the chambers of their shells.
Imagine these creatures bobbing around in the ocean, searching for their next meal.
 
The complete ammonite has been split, and the two halves highly polished, to show the beauty of the interior chambers of the creature.

They make incredible show pieces.
