    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.

    Hm is the spinosaurus bipedal or quadrapedal? (Sorry if i made some typing mistakes)

  • Yanuchi Uchiha: Anime, Games and Ramdomness

    Note that the 'new' Spinosaurus as is stated in the video is most likely a Juvenile...

    meaning it might have developed into a bipedal stance later in it's life. Thus, we need more fossils

    • Toostig
      Toostig Hace 2 meses

      not necessarily. they wheren't thought to be semi-aquatci, and still aren't. not like spinosaurus who we believe spent large amounts of time in the water.
      barynonyx and suchomimus are known to be piscovores, but not necessarily semi aquatic, atleast not nearly as much as we believe spinosaurus to be semi aquatic.
      they also don't shown nearly as much traits is spent time in the water as spinosaurus.
      yes they hunted fish and possesed cone shaped teeth but probably not like spinosaurus and not as often/much as spinosaurus.

    Spinosaurus’ sail may have prevented it from killing itself. When chasing fish underwater it may have found its way into some very tight places under rocks, fallen trees, mangrove roots etc. the sail would prevented it from going so far into underwater hazards where it would be trapped and drowned.

      atleasy not with our current understanding of spinosaurus.
      its part of the Megalosauridae, a pretty large family and no sign of feathers have ever been found. and its a far down the line so feathers on spinosaurus would almost be considered to not be present at all.

    It makes me wonder how JP3 got the depiction of the spinosaurus so accurate to the 2014 discovery. Hopefully the movie didn't influence the aesthetic too much and it was merely coincidence. I like to think that the special effects coordinator for the movie just did his own research with the little information he had and made a realistic adaptation of the spinosaurus before the actual paleontologists found enough evidence to make a calculated assumption of what the creature looked like.

    When you say Spinosaurus was the only known semi aquatic dinosaur, I couldn't help but wonder: Wouldn't the other fish eating dinosaurs like Irratator and Baryonyx be, by default on the grounds of their diet, also be semi-aquatic? And what about the duckbill dinosaurs like Paraceralophus? Weren't they always thought to be semi aquatic?

    Spinosauris is a truly fascinating and mysterious animal from an age long past. Our understanding of it continues to change with time as new specimens are found. Though much about it’s appearance and features remain up for debate, it is without a doubt one of the strangest, most uniquely adapted theropods of all time, and it remains my favorite dinosaur because of this fact.

    A captivating video with a very interesting subject. Thank you very much. As a retired geologist I may say that there were many genera of fish, amphibians and aquatic reptiles. Dorsal fins were there in fish. Dorsal fin like structure were mostly absent in amphibians. In some reptiles similar structures were there. In stegosaurus dorsal armoured plates were present. But none had such japanese hand fan like huge dorsal fin like thing as found in spinoceras. From evolutionary point of view both, the said armoured plates and the bony fin like organs are puzzllng.

    When i was in 2nd grade my teacher at the time made me do a report on a dinosaur. I remember looking at books for hours trying to decide which dinosaur to choose. I eventually settled on Spinosaurus; I remember thinking to myself this dinosaur is special. The information was sparse at the time, they knew it was discovered in africa; but that was it. I spent hours trying to find more information on It, and i did thanks to the to the early internet. I read and read more research about it; which i eventually understood after rereading them so many times. Anything just sate my curiosity; thinking back at it i even formed my own hypotheses about what the sail was used for. That research planted that little seed in me that eventually blossomed to a passion for Science. I'm in college rn majoring in Chemistry; and I'm just coming home to take a small break before i go back and study. Watching this video made me a little misty eyed as this was the reason my insatiable curiosity for the natural world came about. It puts things into perspective , you know?

  • Hanif Huzairi

    From the Spinosaurus Wikipedia page: "A 2018 study by Donald Henderson, however, refutes the claim that Spinosaurus was semiaquatic. By studying the buoyancy in lungs of crocodilians and comparing it to the lung placement in Spinosaurus, it was discovered that Spinosaurus could not sink or dive below the water surface. It was also capable of keeping its entire head above the water surface while floating, much like other non-aquatic theropods. Furthermore, the study found that Spinosaurus had to continually paddle its hind legs to prevent itself from tipping over onto its side, something that extant semiaquatic animals do not need to perform. Henderson therefore theorized that Spinosaurus probably did not hunt completely submerged in water as previously hypothesized, but instead would have spent much of its time on land or in shallow water."
    If this is true, all previous depictions of Spiny would rendered useless but instead re-portray the beast as more of a wader than a truly semiaquatic animal.
