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 explain the video of the GIANT shark caught on tape at the bottom of the ocean ((kinda)) ?? ur saying that they just chilling in warm waters but where it was caught on tape that's estimated -10 degrees or colder due to lack of sunlight but surely it moves around because 1. there would not be enough food 2. they would just be waiting for something to sink that they can eat and most sharks can't just wait so surely the mega would have to move through the levels of the sea eg twilight zones

    I’d imagine the Livvyitan couldn’t kill a Megalodon One on OneThe Megalodon has the larger size, stronger bite force and a killer charge as they sent Whales out the water with their heads, 15 metre long beastsMost likely the decline of whales that ended them off not the Sperm Whales cooler, deadlier older brother

    Poor big boi got starved. Prime example of size isn't everything, it was too big for its own appetite.Edit: Wait she makes a point, giant whales and warmer waters does leave the niche of Megalodon back on the table, our bois the great whites have a opportunity they might actually be taking.

    Why did cetaceans suddenly appear in the earth's oceans 50 million years ago without any relative preceding them???

    You may update the size estimate. New paper measures them at 15 meters long at most. https://www.forbes.com/sites/melissacristinamarquez/2019/10/02/turns-out-the-megalodon-shark-aint-that-big/#4c09820c503b

    We’ve only explored 5% of our ocean floor so we don’t know exactly but they probably still did go extinct
