Why Megalodon (Definitely) Went Extinct

Loading...
  • 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

    How do you know this stuff???if you know comment please.

  • My Name Is Not That Hard To Spell

    You know that barely 5% of the ocean is explored right? And a VERY small percentage (like less than 1%) of organisms become fossils and are found. Besides, people don’t really look for fossils under the ocean. That b*tch could be hiding anywhere

    Bet there’s still more alive somewhere that we haven’t explored yet.

    Actually I would argue that the disappearance of the megalodon seems to coincide rather well with the practice of whales and dolphins to travel in pods. My guess that's what did them in, whales started working together against this predator and it could not cope. The whales could adapt their behaviours way quicker than the shark could adapt it's physiology.

    95% of the ocean is yet to be discovered

    Please stop referring to dolphins as separate from whales.They are literally toothed whales.

    Are you sure... I’m form New Zealand and I wouldn’t be surprised if a couple were chillin in the depths far off shore. Beside, why else would anything come near our shores - they’re too scared of the megaladons.

    My incorrect take away: sharks are descendants of trees.
