It would be hilarious for someone to contact one of the local stations in Wilmington, claim to be from some oceanographic institution, and tell the reporter it was a Megalodon. In this day of Twitter news and unsourced reporting, one of the locals would probably run with it, and never bother to learn that the species went extinct millions of years ago.
Never let the facts get in the way of a good story.
If the shark felt like a Megalodon, then its genetics do not matter. Sharks are allowed to be trans-species too.
