      after these reptiles died out, mammals did the same. Land mammals evolve to live under the sea and some grew to gigantic sizes, e.g. blue whales(largest known animal in entire Earth's history). Other mammals include dolphins and sea otters. Birds, the only descendants from dinosaurs also adapted to live in seas. E.g. penguins. However they are not 100% aquatic and still need to step foot on lands.

    I've been watching all your videos with my nephew when my sister drops him off. He's 6 years old and he has a better understanding of evolutionary biology than most adults in part because of the great work you do explaining these things in terms that even a 6 year old can understand. I have to pause the video to explain certain concepts sometimes, but man, he just gets it most of the time. He's always asking me why there "aren't more dinosaur shows" and I always tell him that there will be more in the future.
    I imagine these aren't easy to make, they clearly require a decent amount of research, script writing, and video editing/art creation. Once the financial burden of COVID lifts off my family's collective chest, I'll definitely be diverting some of that cash to your patreon. Thank you for producing such great educational content - my nephew and I really do enjoy it, and we both learn a lot every time you upload.

      - taking the 1500kg mass estimate for Simbakubwa at face value despite the fact it was developed from a methodology known to be flawed.
      - claiming ground sloths in North American went extinct because things became too cold, when in fact they went extinct as things were getting WARMER (meaning they were more likely wiped out by humans, since the climate was turning in their favour). Then claiming that South American ground sloths got huge to specialize for living in cold climates and became extinct because things got too warm (citing Megatherium as an example), while ignoring that a) Megatherium actually lived in warm climates (again, a likely human-driven extinction here for this reason), and that b) there were plenty of small/medium-sized sloths in South America (and one giant one in North America), so it’s wrong to claim SA ground sloths in general became large and cold-specialized.
      - Their megalodon video originally claimed that in the Pliocene, newly evolved cetacean competitors like Livyatan and orcas contributed to megalodon going extinct, ignoring that a) cetacean competition was not this new unstoppable force, but something that had been a factor sharks had been handling since the Late Eocene, before megalodon even existed, and that raptorial cetaceans were actually going extinct left and right towards the end of meg’s existence (and likely for the same reasons that later killed off megalodon), b) Livyatan evolved in the Miocene, not the Pliocene, and that it actually went extinct at around the start of the Pliocene (a couple million years BEFORE megalodon did), and c) from the available fossil evidence, orcas did not become raptorial predators until after megalodon and all the earlier raptorial cetaceans were gone (the only orca remains that come close to the right age belong to Orcinus citoniensis, and this is a much smaller animal than living orcas and with teeth far less suited for eating large prey; even if we include hunting in groups, this thing likely wasn’t competing with megalodon for prey). Do note that PBS Eons may have realized this mistake, because these issues seem to have been removed.
      - They parrot the claim of borophagine canids being outcompeted by cats despite the fact this hypothesis never made any sense, because cats (including large-bodied ones) entered North America at the start of the Middle Miocene, before borophagines even became a dominant group of large predators. Borophagines had been handling competition with cats since before they actually became apex predators and they managed just fine, so the idea competition from cats outcompeted them makes little sense.
      - Same with their terror bird video-the idea of North American predators outcompeting South American predators during the Great American Biotic Interchange has been mostly overturned, as the South American predator guild (especially apex predators) had been in severe decline since the Late Miocene and all but collapsed around 3MYA, prior to the main pulse of the GABI that allowed their competitors to enter South America. At best, competition from North American competitors was a minor-secondary factor in Titanis going extinct, and cannot be blamed for killing off terror birds as a group-they were already on death’s door before that point from climate-related reasons.
      - In fact, pretty much all of PBS Eon’s arguments in various videos about animals outcompeting and displacing other animals at the group level are parroting poorly supported or even outright disproven hypotheses that only have stuck around due to the fact they’ve become memetic, with nobody bothering to point out all the flaws with these hypotheses.

      @Dragrath1 Před 3 lety +4

      There is some evidence that one lineage persisted for some time but they were quite specialized and didn't rediversify like they had previously suggesting they had quite low genetic plasticity and eventually probably just faded away from competition. That said who knows when you have those dead walking taxa sometimes they are good enough to persist long after you would have thought due to the poor representation of the fossil record.
      That said none has been found past the Cenomanian-Turonian boundary or Anoxia event or Bonarelli event which seems to have been linked directly to the Caribbean LIP(Large Igneous Province).
      So while one lineage did survive the earlier extinction that wiped out their kin they probably were wiped out along with a lot of other marine reptiles in the next mass extinction. Interestingly that is also when the spinosaurids vanish from the fossil record too which suggests their aquatic diet lead them to face the same end as many other marine reptile groups when low oxygen content caused marine ecosystems to largely collapse.
      That event that likely did finish off the last Ichthyosaurs and spinosaurids however opened the way for the Mosasaurs to rapidly diversify into empty niches and claim the oceans as the top predators up until a major asteroid blasted into the coastline of Laurentia/North America.

      @@milu3779 Well, here's what was happening on Snaiad back in the Mesozoic:
      250-183 million years ago:
      Modern “Vertebrates” with four legs, two heads and hydraulic muscles diversify and dominate most terrestrial ecosystems. Most of them, however, belong to archaic lineages such as Archaeognaths, Tridactyls, Tetradactyls and Polydactyls. Continents approach present positions. Rampant Hexapods still hold out in Oroland, then an island continent.
      183 million years ago:
      Mass extinctions claim many Archaeognath, Tridactyl and Polydactyl species. Tetradactyls are wiped out, Hexapods almost so. Evolution of Spinostomes and Lophophids. The continent of Thalassia forms after an orgy of mid-ocean volcanism. Declining forests of giant trees give rise to first pinnacle ranges.
      183-80 million years ago:
      Spinostomes and a second radiation of Polydactyls dominate most ecosystems. First Jetocete-like animals develop. Most “Vertebrate” herbivores still lack well-developed food processing systems. Arthrognathans diversify underwater, one group launches a second invasion of land almost 800 million years after terrestrial Arthrognathans die out. Poorly-understood “vertebrate” groups colonize Thalassia, the origin of Monoanticherans, Titans and Tromobrachids. Sproglands expand over mainland continents. Indigenous tetrapod “Vertebrates” replace Hexapods on Oroland, still an island.
      80-40 million years ago:
      Many modern “vertebrate” lineages, including advanced herbivores, evolve. The final flowering of advanced Spinostomes on mainland continents is followed closely by their rapid decimation in the face of new competition.

    My guess of the long neck is for supercavitation, like swimming inside a bubble rather than swimming in the water. Some sea-birds do this while diving, and Penguins are master of such thing. Fish uses the whole body to generate thrust, supercavitation reduce the drag but also propulsion, which doesn't work for fish. Flipper swimmers, however, can have their body inside the bubble while the fins outside the bubble for propulsion. I think Plesiosaurs may look like an oversized version of Penguin, swim near the water surface at a very fast speed. They're too heavy to jump out the surface, but using their head to go up-and-down the water surface to breathe and bring-in more bubbles for swimming.

    I think the long necked plesiosaurs are pretty underrated. They are always just depicted as pliosaur and mosasaur bait or pursuers of small fish/squid. Something like an elasmosaurus has big moray eel like teeth and heavily reinforced skull. Like an eel its going to be tearing chunks out of things.

    • @z1az285
      @z1az285 Před 2 lety +2

      My thoughts exactly. There is evidence that a elasmosaur swallowed a juvenile mosasaur from stomach contents. But I'm sure such a massive animal with a 2 foot skull with large teeth could attack small mosasaurs as well as wounded animals

    Random thought:
    If the long neck is able to bend downwards easier than other directions, and the long neck extends its reach, could it have been an ambush predator that specialized in eating things off the sea floor from enough distance that the prey didn't recognize it as a threat? Requires that the downward bending is also capable of striking fast.

  • @bkjeong4302

    So plesiosaurs, like dinosaurs, became dominant because the End-Triassic Mass Extinction killed off the former dominant clades.
    Plesiosaurs actually varied extensively in dentition and jaw structure even excluding the pliosaurs; elasmosaurids, for example, had stout, rugged dentition (to the point they resemble that of large crocodiles) along with more robust skulls (in several cases developing shorter snouts), while cryptoclidids went the opposite direction, with relatively frail jaws and teeth.
    P. funkei was a bit less than 9m long, the largest pliosaurs are Pliosaurus macromerus, Sachicasaurus and Kronosaurus queenslandicus at 10-11m in length.

    Always found it strange that the mythical Loch Ness Monster was described as possibly being a plesiosaur. For a start, they were air breathers, so we'd see them sticking their heads out of the water frequently.....add that to the fact that the Loch was only formed around 10,000 years ago, and Dinosaurs have been extinct far longer.

    • @pocketmarcy6990
      @pocketmarcy6990 Před rokem

      The way Plesiosaurs breathed was also very interesting, as the likely just stuck their heads out of the water vertically, unlike the common depiction of the whole body floating on top of the water

    surprised how obscure nothosaurs are today despite such iconic animals as plesiosaurs evolving from them, regarding the theory about plesiosaurs being stem-turtles of a type I instantly thought of Jules Verne describing a plesiosaur as "a snake pulled through a turtle shell" in his novel "Journey to the Centre of the Earth"

    What if their long necks were used to invade crevices and burrows in reefs that small fish fled to hide in? Such crevices would only be accessible by other small fish that would be putting themselves in danger picking on a fish their own size. Ironically, modern eels do the opposite. They hide in small burrows and pack up so that they seem like an unassuming threat, but can actually extend quite far from it instantly.
