Description
Crawling around on the bottom of the black water Cooper river in the South Carolina lowcountry sounds scary and it definitely can be when you consider the giant alligators swimming around the ripping currents in the near zero visibility conditions. Why do something like that?? To find treasures like this amazing and rare giant thresher shark tooth! This fossilized gem from a prehistoric shark is over 10 million years old and is close to the maximum size for the species, Alopias grandiis.
