Polished Ammonite Split Pair - 4.492" Cleoniceras 21stcentury Split specimens are precision cutAmmonites are an extinct group of cephalopods that entered the fossil record 400 million years ago. This specimen is a 4. 492" polished Cleoniceras fossil from Madagascar. The fossil has been split into a paired set to showcase the beautiful internal chambers of the shell. These internal chambers are called septa and the ammonite could fill them with air in order to float through the ocean like a balloon. After millions of years, they are now
