    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.

  • critterfreek82

    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!

    • Will Smith
      Will Smith Hace 4 días

      Yeah but he was not a quadruped because his hands could not support his body and he is also front heavy and someone did the math and discovered his legs needed 27% bigger so no hard feelings.Then again we still don’t have a complete skeleton

    • Toostig
      Toostig Hace 4 días

      You have no evidence of spinosaurus legs being that large,
      In 2013 we found the specimen fsac kk 11888, the specimen is based of from different individuals but it was stated that all the bones where around the same age(17+2 years old) we found the legs which belonged to the neotype of this specimen. It had short legs as far as we know.
      And the study which suggested spinosaurus couldnt float was highly flawed and shouldnt be taken as a fact

    Spinosaurus was the apex predator of riverine environments, just as Trex dominated on land, and Mosasaurs dominated in the sea (which were marine reptiles and not technically dinosaurs).

    • Toostig

      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.

    Alan Chihak Hace 2 meses

    In my personal opinion, spinosaurus was neither bipedal or quadrupedal. While theropods couldn't walk on their knuckles or or face their palms on the ground, spinosaurus easily could have balanced a portion of its weight on the sides of its hands and fingers on the ground while walking. Plus, we've never found any fossilized spinosaurus hands, meaning they could have had wrists unlike those of any other theropods. But we have found legs, and those legs were short. That means that whether or not spinosaurus was quadrupedal, it couldn't have been fully bipedal like in Jurassic Park without falling flat on the ground, likely killing themselves. The only reason bipedal spinosaurus exists is because 80s and 90s paleontologists assumed that it was basically a big aquatic baryonyx with a sail.
