Answer 1

Well, most of that 95% is in places that a creature of that size could not live.

Plus, even then, you’d expect to see **something**. Sharks, including the megalodon, shed rows of teeth routinely. Modern sharks lose an average of 1 tooth every week; their mouths are like conveyor belts replacing row upon row of knives on the regular.

In order to say Megalodon still existed, we’d need to explain how we can’t find a single, non-fossilized tooth, when each averaged around 6″ long each. It would be more believable to say The Tooth Fairy existed; because it would have to exist before the megalodon could xD
