Ammonite Fossil Matched Halves Box - Jurassic - Cretaceous - Actual Authentic Fossil
From our Museum Field Kit(tm) collection this is an Ammonite which has been split in half and polished on one side. Ammonites first appeared in the seas 415 million years ago. During their evolution three catastrophic events occurred. The first during the Permian (250million years ago), only 10% survived. They went on to flourish throughout the Triassic period, but at the end of this period (206 million years ago) all but one species died. Then they began to thrive from the Jurassic period until the end of the Cretaceous period when all species of ammonites became extinct. During medieval times ammonites were believed to be petrified snakes.
