Ammonites are cephalopods. They were predatory, squidlike creatures that lived inside coil-shaped shells.
Like other cephalopods, ammonites had sharp, beaklike jaws inside a ring of tentacles that extended forward from their shells.
Ammonites continually added on new shell segments as they grew, but only lived in the outer chamber.
Their method of locomotion was much the same as the modern day Nautilus that squirts water from jets in order to move backwards through the water.
Exceptionally preserved and polished Ammonite split pair shows exquisite detailed chambers. The color is exquisite yellow and sienna to brown. Some of the chambers exhibit crystals within the voids.
