Did you know that the average shark sheds approximately 1800 teeth a year? Over 20 thousand in a lifetime! Now go back,way back, 60 million years ago when huge sharks roamed the shores of what is now Charleston, S.C. These Megladon sharks, with lengths up to 100 feet, drove ancient whales to their deaths in the shallow waters of the tidal basin. In the rivers, fossil fields scatter the bottom. Thousands of years of eroding clay banks have deposited these wonderful artifacts for the willing diver to find. Advanced divers with good lights will be rewarded a bountiful return for their efforts!
