Why Megalodon (Definitely) Went Extinct

  • For more than 10 million years, Megalodon was at the top of its game as the oceans’ apex predator...until 2.6 million years ago, when it went extinct. So, what happened to the largest shark in history?

    As some of you have pointed out, the size comparison we show at 9:36 features a humpback whale instead of a blue whale. That's my fault! The illustration (from a stock photo site) was improperly labeled and we missed the mistake in our review. We spent so much time making sure we had all of the extinct species depicted accurately that we missed the (enormously) obvious error right in front of us. Sorry for the mistake! -Seth

              Other than 'we can't find any fossils' there's nothing listed that guarantees they went extinct. Kinda seems like a pompous video title after having watched this. People said the same thing about giant squids for ages and treated them like mythological creatures. We thought the coelacanth had been extinct for millions of years until we found out they were still alive. 'Why We Believe Megalodon Went Extinct' would be a more accurate title.

                Especially when you consider that we haven't explored most of the ocean which makes up the majority of our planet, so we haven't explored even most of our planet.

                          If megalodon existed today, it would have been one of the most dangerous animals to be filmed underwater, for research and educational purposes. Hell, even hunting that thing for sport would have been even crazier.

                                    The six gill shark. The frilled shark, Goblin shark, mega mouth, the celocanth. These are prime examples of prehistoric fish which presumed to be extinct found today upon mosasaur and plesiosaur. There are even legends in warm gulfs of a massive nocturnal shark. Scientists travel to find their own answers without hearing the history from culture. Pterosaur “thunderbirds” as well. In select Unsearched and “useless” wilderness where natives were driven from their homes or put into schools where they have no voice over science, there be a tale or two outside of institutionalization.

                                      But that does not mean that it went extinct, 95% of the ocean still remains unexplored. They could be anywhere in that 95%.

                                        So what you're telling me is that, by your logic, since the entirety of Earth isn't explored, dinosaurs are actually just out there vibin'?

                                      It may be very likely that it's gone, but we haven't discoverd more than 5 prosent of the ocean, so putting (Definitely) in the title would be a wrong description in my opinion

The fossils had been encrusted with manganese dioxide. The scientist believed manganese dioxide layers had built gradually over time and also accepted another scientist's measurement of time for the deposit of manganese dioxide. he came to the conclusion all he had to do was measure the crust to date the teeth. Many factors are involved with the deposit of manganese dioxide, which don't make this a reliable dating method. Moreover, the scientist didn't take into account that fossils can redeposit. It is still a popular claim to this day that we have such recent teeth. Alas we don't...

Whales are already endangered if there were Megaladons still roaming our oceans we'd know it that thing hunted whales! and it ate several of them a day there would be an overhleming amount of evidence if such a monster like Megaladon were still in our oceans. The thought of Megaladon hiding down in the Mariana trench is an interesting one like they did for the movie but Scientefically it's impossible for many obvious reasons.
