Here is a very pretty ammonite from the Cretaceous of Madagascar. This thick-bodied ammonite has been cut in half, and both halves have been polished to make for a beautiful display. The coiling pattern of the mollusk and the individual body chambers of the cephalopod are both easily seen. Many of the body chambers are hollow and filled with crystals. The outside of the ammonite has a slight iridescence preserved. This is a very striking example of a split ammonite from the exotic island of Madagascar.
