SHARK TEETH

SHARKS SHED THEIR TEETH ON A REGULAR BASIS. WHEN THEY DO, THE TEETH USUALLY DROP TO THE BOTTOM OF THE OCEAN AND ARE COVERED UP WITH SAND AND SILT. GO BACK IN TIME--60 TO 65 MILLION YEARS AGO--WHEN THERE WERE ANCIENT SEAS AND SHARKS SWIMMING IN THEM. TEETH DROPPED, WERE COVERED, OCEANS DRIED UP AND THE FOSSILIZATION PROCESS BEGAN AROUND THE END OF THE CRETACEOUS PERIOD AND THE BEGINNING OF THE PALEOCENE EPOCH. WITH HEAT, PRESSURE, AND UPHEAVEL, THESE FOSSIL TEETH ARE NOW COLLECTED AND PREPARED AT KHOURIBGA, MOROCCO.
