They are pre historic great white sharks with jaws large enough to swallow a school bus whole.
No Way... How do I know that's true?
It's true, yo!!
Loads of fossilized megalodon teeth have been found, lots in North Carolina actually.
Whaaat? That's cray.
Right? One collection of megalodon teeth was found by the same person on the North Carolina coast in one weekend. The teeth were then used to reconstruct an entire megalodon jaw to scale.
Where can I find this jaw replica?
There's one at the NC Museum of Natural Sciences, and another at the Baltimore Aquarium.
