These are real megalodon super-shark teeth! Megalodon was the largest shark to ever live (reaching an estimated length of 18 meters or 59 ft) and fed on whales!
This fossilized, imperfect, specimen was found in the Hawthorne Formation of South Carolina! Amazingly enough, a modern coral has grown on this prehistoric specimen! It measures ~4" long.
