SEMINOLE – A 16-year-old high school student has discovered what archaeologists say could be the biggest fossil find in Pinellas County in nearly a century.
Sierra Sarti-Sweeney was practicing nature photography in a heavily wooded area of Boca Ciega Millennium Park in Seminole last month when a shiny black rock caught her eye.
She took it home to show it to her 22-year-old brother, Sean, a geology student at the University of South Florida. After some Internet research, the siblings came to two conclusions: The football-sized rock was actually the tooth of a long-extinct mammoth, and they were in over their heads.
