The Triassic period was the first period of the Mesozoic era and occurred between 251.9 million and 201.3 million years ago.

It followed the great mass extinction at the end of the Permian period and was a time when life outside of the oceans began to diversify.

    Nice, I have been looking forward to part two!
  • @Thomas_Name
    I love art like this thumbnail where a creature is standing in a shallow pool of water and a BIGGER creature is jumping up at it from great depth at less than a meter distance 😂
  • @hoppish088
    Love the mammals getting a flowering plant in the Triassic. 6:12
  • Fun Fact: Did you know in Triassic that 95% of land animals are Lytosaurus, a group of Therapsids and Lytosaurus dies in the Late Triassic when Jurrasic Period is now starting to rise. Because of this, The Age of Therapsids or Synapsids end during the late Triassic, not the end of Permean Period.
  • @PolarBearFan24
    Can you make a part 2 to the “What was Life Like During The Permian Period”? Awesome video as always!
  • @user-gw4rz7mk7q
    Thank you for listing sizes in meters and feet. Excellent video.

    The superxontinent wasn't "known" as Pangea. It's what we call it now that we figured out it existed.
  • @prototropo
    Therapsids and mammals, both from Synapsida, were not reptiles or reptile-like. Reptiles, from Sauropsida, were not mammal-like. The synapsids and sauropsids both diverged from the first amniotes, with synapsids being the ancestors of mammals, and sauropsids the ancestors of all reptiles, including lizards, snakes, crocodiles, pterosaurs, ichthyosaurs, dinosaurs and finally, birds. But mammals were never reptiles.
  • @ShadySheev
    Would be nice of you to add the names of the artists into the video. As a courtesy but also because I would have loved to look up some of the amazing artwork myself.
  • @jamesburke6078
    If I know anything about mammals it's there's going to be one that defies all that!
  • @floweryomi5351
    Someone's already pointed out the Ceolophysis issue right?
  • The giant salamanders of Japan and China look very much like relict temnospondyls
