Turtle Beach shark teeth

I checked it out about the shark teeth.  Apparently they are found on Turtle Beach, on the south end of Siesta Key.  But not on the fine, white beaches.  I’ve been there several times and never found a tooth.  Now, across the pass and a little further down on Casey Key I’ve found tons, just by setting down in my beach chair and looking around.  I suppose that man I met today on Siesta with the shark teeth was just lucky.  But I’ll keep hunting for them.
