Though there are oftimes revelations of previously extinct 'critters' that are discovered (usually around Madascar or New Jersey)........and those
discoveries are in fact fascinating examples of the durability of some life forms............. a living, function Megalodon would have such a
voracious appetite, that it could not possibly have gone unnoticed.
It would have cleaned out long ago, major areas of fishing in our oceans, and surely have been spotted based only on this 'wake of destruction'
Cool idea though.
Take heart.......... there are lots of other places for lesser varmints to hide.
