Giant Polished Jet-Black Megalodon Shark Tooth

This is a giant polished jet-black Megalodon tooth. It measures 4-1/2″ long and 3″ wide.  Because it has been exposed to sand and gravel for many years, the reverse side blade had damage and has been ground and polished to a glossy shine. I found it diving recently in 40 feet of water near Savannah. Includes display stand and certificate of authenticity.
