“Our dedicated team of underwater archaeologists has done an incredible job of documenting and researching the Manasota Key Offshore archaeological site, and I am extremely proud of the work. Our hope is that this discovery leads to more knowledge and a greater understanding of Florida’s early peoples.”
Since manatees swim up creeks to stay warm in the winter in the springs, and flintknappers seek stone in creeks to knap, and Indians used shark teeth as tools and ornaments and also ate manatee meat... it would be expected to find these things in FL creek beds whether or not the area was ever under water.
