Ammonites are extinct invertebrates that shared the same fate as the dinosaurs, going extinct at the end of the Cretaceous Period, 65 million years ago.  Modern relatives of ammonites include the nautilus, squid, cuttlefish and octopus.  Because ammonites lived exclusively in marine environments, their presence also indicates the location of prehistoric seas.  Ammonites varied greatly in size.  The largest known ammonites have been found in Europe and grew to massive sizes exceeding 2 meters (6.5 feet) across.  This is the exception, of course.  Average diameters throughout the ages showed that most ammonites grew to sizes not much larger than a man's hand.  Some ammonites were only as large as 2 cm (0.75 inches) in diameter.
