    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鈥檚 only known semi-aquatic dinosaur.

    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?

    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.

    Spinosaurus (Spinosaurus aegyptiacus) was indeed a peculiar dinosaur given that members of its family of theropod dinosaurs are known for their elongated crocodile-like snout.

    It makes you wonder what kinds of things Spinosaurus would have given rise to had it continued to evolve past the K-T boundary. We would probably have far fewer crocodiles, at least in Africa, instead maybe something kind of like a Mosasaurus- Spinosaurus hybrid.

    can someone clear something up for me? she said there is no evidence of other aquatic dinosaurs not even semi aquatic ones. So what about all the plesiosaurs, mosasaurs, itchyosaurs. And I thought we beleive that the baryonix was semiaquatic.

    I remember as a boy in the early 1990's enjoying noshing on dinosaur-themed graham crackers, with Spinosaurus being one of the species. It very much looked like Stromer's reconstruction, and so did all the Spino renditions in my books. How radically our concept of it has changed since then!
    And just the other day, I read about a 3-D, computer modeling study that turns all of this on its head, purporting that Spinosaurus would actually have had quite a bit of trouble staying upright or managing to dive under the surface, and would NOT have been able to move on all fours. This is very much a case where we'll just have to see what develops!

      Kinda, its skull was completely different(maybe a gharial but not even close to a gator or slat water croc) it did posses the pressure sensores like a croc and conicol teeth has nothing to do with being like a croc, its the most common traid for fish eaters.

  • OctoGuy

    The small back legs of spinosaurus were from a juvenile because first of all, the leg measurements were all wrong. The bones around the pelvis needed to be increased by 20% and it couldn't walk on all fours like we do so the scientists announced that it need to walk on its knuckles much like a gorilla would, but to do this it needed to have reinforced knuckles. It didn't have them. Blus it needed to keep its claws sharp in order to catch its slippery prey items in the water. And how on earth could a knuckle walker be able to catch the fast moving Ouranosaurus and combat his rival carcharodontosaurus when droughts occurred, which, there is evidence for by the way. Just to say, spinosaurus was definitely not too front heavy to walk just on all fours. Take T rex for example. So all that in mind, we definitely can say that spinosaurus was not just a water dweller but a land animal at times.
