This is a lot of broken fossil Megalodon (Carcharocles megalodon) shark teeth recovered from the Peace River in Florida's famous Bone Valley formation. They date from the Miocene period (approx. 5-23 million years ago).
These are partial and incomplete teeth. They have been tumbled around the water for aeons and been dinged up and polished before turning up in my sifter at a gravel bar in the river. These pieces consists of blades and partial blades with some root attached.
Refer to the photos. The black centimeter cube is shown for scale and is not included. You are purchasing all of the pieces shown. The lot weighs a total of approx. 30g (or a little over one ounce). Your purchase will include an ID label with locality info.
