The Weird, Watery Tale of Spinosaurus

  • Publicado el 8 may 2018
  • Check out our NEW POSTER:
    In 1912, a fossil collector discovered some strange bone fragments in the eerie, beautiful Cretaceous Bahariya rock formation of Egypt. Eventually, that handful of fossil fragments would reveal to scientists one of the strangest dinosaurs that ever existed -- the world’s only known semi-aquatic dinosaur.

    What about big sea dinosaurs or something similar? I don't really know what that big thing is in Jurassic World, the one underwater but I found it both fascinating and terrifying. It actually became my favorite since I love fishes and underwater creatures. So it'd be great to know more of those kinds of things from back then and whatever period they came from.

    I still miss a few points in this video. First of all, the fact that the Spinosaurus is both, bipedal and quadruped. Used both propulsion possibilities when it was needed. Second, the Spinosaurus could not walk on the knuckles, as many think. Because of the weight, these knuckles would break too often. And last but not least, the Spinosaurus was not only a fish eater, but also ate (little) dinosaurs, tortoises, and did not hesitate to snatch a Pterosaur from the air every now and then.

    'No other semi-aquatic dinosaurs' But, but, but .... What about Halszkaraptor, which shows evidence of adaptations to a semi-aquatic environment? (it was only described late last year, so depending on when this video was made the report might not have been out yet) BTW, I really like these videos and find they very interesting.

    What about Suchomimus? I was reading Wikipedia and Sucho and Spino lived at the same time (although Sucho was in Niger, Spino in Morocco), but the fossil evidence still portrays Sucho as a more "typical" carnivore who could walk on its back legs and having short arms. Sucho is the one who "stayed" in the ground whereas Spino went for the amphibian lifestyle? If anyone has a paper or a video, I'd totally appreciate that :D

    Oh my. Think of this animal as a toothed Heron or Shoebill Stork not some crocowhale, This current reconstruction is a very wild speculation based on far spread fossils and many different representatives of what is likely more than one species. In the end Spinosaurus will be found to be a very large but very svelte, mostly piscivorous wading animal like most modern herons, some storks and other shore/wading birds of today, not some alligator seal nightmare that couldn't even haul itself ashore according to current reconstructions to nest and and clutch eggs. Think great blue herons, Shoebill and marbou storks when considering the behaviour and lifestyle of this enigmatic creature, not the chimerasaur rapidly rushed to dissertation to monopolize dwindling grants and funding for 'celebrity' paleontologists.

    Just to be clear... the evidence of what the spinosaurus looked like was published in 2014 while the jurassic park 3 movie came out in 2001. This cool analogy proves that the spinosaurus has gone through some changes while keeping its own very similar appearance. Guys, this is how dinosaurs were conserved throuhout the ages !!! 🙄😎

    I have a hypothesis that spinosaurus was a shallow water/swamp dwelling predator. The sail was multipurpose, and i think it served as both a way of temperature regulation, mating and intimidation as well as a tool for swimming and hunting.

  • M Parker
    M Parker Hace 28 días

    It seems like the hind legs were not strong enough to support the weight out of the water. Crocs can't stand on their hind legs. Seeing the sail, I'm surprised modern crocs don't have the sail to get some sun while the body is submerged in cooler water. Also bones on the belly? Doesn't that sound like it was dragging its belly around, instead of walking?

    When I was in kindergarten, my teacher made the class present what we wanted to be when we grow up in fornt of the group. When it was my turn to present, I said that I wanted to be a spinosaur. Today, I can safely and successfully say that am a spinosaur. It took a lot of surgery, but I hired the best. People can't tell the difference. I don't just look like a relic of the past, I am a relic of the past.

  • batt3ryac1d

    I like the theory that the sail was for thermal regulation. Water would be pretty cold for a reptile so maybe the sail let it sun while in water.

  • Phil PBOY
    Phil PBOY Hace un mes

    It seems quite obvious to me that this dinosaur must have lived mostly in water, using its fin to catch sunlight for heat.. which is more necessary if the entire body spends most of its time submerged in water. It had heavy bones, like whales, not light bones like typical land dinosaurs... it was also very wide which probably added to a ballast effect. I also imagine it walked on all four’s and was quite similar to modern day crocs when on land. I’m not quite sure what on Earth the spinosaur in Jurassic Park was about lol

  • valinperal
    valinperal Hace un mes

    I figure the sail would have helped both make it look bigger and when most of it's body is in the water the sail could stick out so if the water is cold the Spino could turn it's sail to the sun to warm it's blood easily without having to leave the water. Also the sail fish idea sounds good for when it's in deeper waters but that might not have been something every Spino would do.

      It was both. It could walk on it's hind limbs if needed but because it was so front heavy it most likely mainly walked on all four. And because it had huge claws on its front limbs it probably walked on its knuckles.

      They just re-designed Baryonyx with a giant body and a sail. Baryonyx was related to Spinosaurus, so there are a few similarities in relation to it's snout. It's not accurate however to the modern Spinosaurus.

    Original archeologist finds fragments and makes his mark in history, but the war destroyed his works, and years pass and many people forget, until one scientist (who admires the archeologist's work) looks for clues until he has nearlt given up, until a mysterious fossil collector gives him a crate with a spino sail bone. Then, he strikes gold!
