Giant theropod, large sail, big bulky arms with giant claws, and is always debated about? Sounds like Spinosaurus right? WRONG! This is Oxalaia, the Spino's Brazilian Twin.

    Man spinosaur fossils have bad luck not being destroyed in museums
  • @rl9217
    If I had a nickel for every time spinosaur fossils stored in a museum were destroyed, I’d have two nickels. Which isn’t a lot, but it’s weird that it happened twice, right?
  • @lewycraft
    It is kind of ironic, that even their finding history is simmilar. Both got their only fossils destroyed shortly after discovering, due to destruction of the museum they were held in.
  • @mgg1244
    bro, they found two bones and were like: Yup it was a master fisherman, had a bite force 20x that of a wolf, went to college in 1982, and had a crush on his gym teacher.
  • @DeinosDinos
    Tragically analogous that Spinosaurus for the longest time was also known from very little fossil evidence. The holotype was destroyed by allied bombing during WW2. Wasn't until Paul Sereno much, much later that we got a better idea of what Spinosaurus was like. So if someone rich is watching or reading this, fund an expedition to the Alcantara formation!
  • @astralb.2647
    The burning of a museum of that size is just so unimaginably tragic for us nerds... we want answers damnit!
  • @kentl7228
    I wonder if 3d scanning and ct scanning to solid models of rare fossils should be mandatory to prevent the complete loss of precious specimens to history.

    Spinosaurid fossils try not to be destroyed challenge difficulty:IMPOSSIBLE Edit:THE AMOUNT OF LIKES
  • @Khan-rz8qi
    Spinosaurus: Hey twin!! Oxalaia: Yoo! 🤝🙏🤞
  • I cried so hard of anger when the museum burned down. Unfortunately, Brazil and historical preservation and memory don't match well. Some improvements have been made, but very slowly
  • @CeratsTheCrunch
    As a Brazilian,i can confirm the existence of these guys. I've seen them mostly in small,deep rivers. They get beautiful in the mating season. They seem to be scared of fire, don't know why tho.
  • @MrPapamaci88
    Spinosaurids in my opinion were a mix between a crocodilian and a grizzly bear. Fisher or not, that's a terrifying combo!
  • @NM-ue8on
    Spinosaur fossils trying to not get destroyed challange : impossible
  • @colekesten9596
    If the Jurassic franchise ever wanted to have a paleo-accurate spinosaurid they could introduce the oxalaia
  • Thank you for mentioning this guy, I've seen it soo many times in paleo books but always wanted to see it in a documentary someday.
  • @riddick7082
    How do they know Oxalaia was pretty much a Spinosaurus twin? The only fossils that have been found of Oxalaia are part of an upper jaw and some smaller parts of the snout.
  • @GuiAntonioli
    It's widely known here in Brazil not only they existed, but they never really went extinct. They evolved and adapted. Nowadays they are way smaller and are called "chupacabras", a common pet to us Brazilians.
  • @thelittleal1212
    What an odd coincidence that I’ve just published a stopmotion video on oxalaia today as well😅
