Answer 1

Every living creature leaves behind some sort of “footprint”, and that is especially true for apex predators like the great Megalodon. Aside from stuff like teeth and bones, a monster of that size ***will*** reshape the whole ecosystem around it so unless they somehow developed the ability to hibernate for millions of year, for whatever reason, Megalodon is definitely off the menu.
