Man using a dredge basket searching for shark's teeth in the sand at beach at Venice, Florida.
The Venice coastal area, just south of Sarasota, sits on top of a fossil layer that runs 18-35 feet deep. With storms and waves, the fossils are slowly driven into the shallow waters and then up onto the beach. Most people who look for shark teeth simply stroll along the beach scanning the sand for the shiny black teeth. The sifter basket seen in the picture helps that process and claims to be more efficient.
