5.2" Fossil Whale Bone - Shark Tooth Mark (Megalodon?)

This is a 5.2" wide, shark bitten, fossil whale bone collected in South Carolina. What's interesting about this bone segment is that the gashes in the bone were almost certainly caused by another tooth, likely a large shark as it fed on the whale. These whales would have been a food source for the gigantic Megalodon sharks living at the same time.
