Why Megalodon (Definitely) Went Extinct

  • Published on: 19 December 2018
  • 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

    Only 20 percent of the seas have been discovered so there might still be a megalodon

    It went extinct because they ate everything out there! MOFO had a bite force of more than 44000 PSI, putting T-Rex absolutely to shame!

    Don't assume this until we discover the rest of the 95% of our oceans.

    The fact the Megalodons are extinct may or may not still be true. Someone told me about a Nat Geo article they read where a group of marine paleontologists found Megalodon teeth that carbon-dated to around 250 years ago. This means that, at least 250 or so years ago, there was at least one live Megalodon still in the ocean. For all we know, Megalodons could still be alive. If that's not nightmare fuel, I don't know what is.

    Think tho we have only discovered 5% of the ocean so anything similar could exist or even a descendent of megalodon

    You can’t confirm the extinction of megalodons, mosasaurs, etc, because they would have had millions of years to evolve into extremely deep divers, and we have only uncovered 5% of the ocean.

    The megalodon still exists because I want it to exist in my head

    To those who say "OnLy 5% oF tHe OceAn Is ExPlOrEd", I give you this.These 5% are all of the shallow waters, coral reefs, islands and a part of deep waters. A shark cannot live in the other 95% due to he fact everything else is cold and deep turmoil. No, they don't live in the mariana trench. No, they don't live near some abandoned island.

    They probably aren’t living now but 71% of the surface is oceansAnd that’s just surface OH HO HO YOU DON’T EVEN WANNA KNOW HOW DEEP IT CAN GO(Dips entirety of Mount Everest in ocean)(Doesn’t even touch bottom of the ocean)

    Us humans haven’t discovered the whole ocean we only discovered 5% and there is still 95% of ocean left to discover and the last seen Megalodon was in 1952

    My thumbnail photo is of my Megalodon tooth. I dug it out on a trip to Scientist cliffs state park in Maryland on the Chesapeake Bay in Calvert county. I found my tooth some 35 years ago. Now if you find any fossils you must surrender them to the park police before leaving. They know the value of Meg teeth and other fossils and will arrest anyone trying to keep them. It's the same at Calvert cliffs state park. My Meg tooth is over 6 inches root to tip and still sharp enough to cut thru a steak like butter.
