All my life, I've been living with an unrealistic standard of Spinosaurus. It wasn't the giant heron with a bad attitude that everyone used to say it was, it was more of a mutated giant dinosaur crocodile that ate freshwater sharks. You learn something new everyday.
I'm sure Spinosaurus ate more than just sharks. At 50 ft long, it could probably take down small sauropods and carnivorous land dinosaurs. But you can't call it a "unrealistic" standard because the only two full skeletons were destroyed in WWII so no one could actually study the damn thing until only a few years ago. But all that aside, it is still a ground breaking discovery.
Adam Webster ***** I think Spinosaurus is a very cool dinosaur myself (Probably my favorite Spinosaurid) but looking at the anatomy of Spinosaurus, I personally think it was more suited to small and medium sized prey. If you want me to give an example, Onchopristis numidus (7 meter long sawfish), Ouranosaurus nigeriensis (small-medium sized hadrosaur living in the same region) and some large freshwater sharks would be more than suitable prey for a Dinosaur like Spinosaurus. On top of that, the aquatic prey it hunted was far from peaceful. A giant 7 meter long sawfish with barbs large enough to cut an elephant in half and freshwater sharks with the attitude of a modern bull shark are just as scary as any terrestrial animal living at the same place and time.
Adam Webster You'll notice that I specified how dangerous even the aquatic prey at the time was. I simply find it frustrating when another person tries to discredit Spinosaurus by bringing up the fact that it hunted aquatic prey. Those people seem to think that the aquatic prey it hunted were giant salmon and harmless river fish. They never stop to think that perhaps a 7 meter long sawfish and a prehistoric freshwater shark are just as dangerous as anything that other large terrestrial carnivores might hunt. Also, Spinosaurus is the only Theropod Dinosaur I know of that preys on and terrorizes sharks. The only other animals I can think of that do the same thing are Mosasaurs and other sharks. If that doesn't make you soil your pants, I don't know what will.
Adam Webster Good point. But I said, "Spinosaurus is the only *theropod dinosaur* I know of that preys on and terrorizes sharks.". Its also quite possible that it's the only non-icthyous, non-cetacean animal that hunts sharks. Orca whales are cetaceans.
***** I used to think things like that too. You're getting there, dude. Just keep on going with it. It's not easy. It takes years, but it totally gets better, I promise. The big one is dying. Once you're over that, it's a cakewalk.
***** There is no longer any simple thermodynamic model for the universe, due to our increased understanding of vacuum energy density, macroscopic quantum effects and maximum possible entropy rates. The "heat death" predicted by the 2nd Law does is 200 years old and does not factor in the latest work on QM. Flows of energy, constant variables, heat phase transitions and gravitational potentials across system boundaries cause changes in a microsystem's entropy. These make natural occurrences not only possible but inevitable.
Maybe you should to back to where the spino bones were found and look round areas very close to it and maybe you might find another fossil maybe a relatively complete one
The earliest known penguin lived around 60 million years ago. Spinosaurus lived around 112 to 72 million years ago. So looking at the timeline, yes it was.
On the duration of scientific inquiry (2:15- 4:17): "...A problem started today may not reach any scientific solution for generations. The man who begins the inquiry does not expect to learn, in this life, what conclusion it is to which his labors are tending."
where did you find the New spino bones or whatever to find out what it's like? because if it wasn't in egypt there's a chance that the spino that is bigger than rex might still be a thing
Morocco as far as I understand all specimens after the holotype have been found there, Spinosaurus is still larger than T.rex by a large margin (10 feet) it just appears to be even more aquatic than we previously thought but that makes sense Baryonyx and Suchomimus which were earlier Spinosaurs already appear to be more adapted to hunting fish than other dinosaurs so it's only natural that the group would evolve to be more specialized and by the time of Spinosaurus true giants.
Huw Brockway I think for a while they considered them different species e.g Spinosaurus aegyptiacus and maroccanus but as far as I know they stopped viewing them that way.There is some debate about the length of the rear legs (they might be 25% longer according to some) but either way Spinosaurus is one of the shortest legged therapods and was probably very slow and ungainly on land sorry if your a fan of the Jurassic Park version, me I like the new version it further complements Spinosaurus weirdness.
it's fine, i don't really like the new spino, i like the one in the documentary, the one in JP was a bit bad, rex would have killed spino with the bite and spino would have most likely killed rex with his claws
+Nicholas Bradley So the skeletons of the real dinosaur from the real life is fake cause you saw made up spinosaurus from jurassic park 3 you mean ? ...
blomgren182 No, the knuckle walking is wrong because of the way the shoulders are built. I didn't say anything about Jurassic Park, that movie got everything wrong.
Nicholas Bradley Do you have some bones to prove us wrong? I mean they got loads of bones how can they be wrong? Do you have a degree in bionmechanics ? I mean we can speculate. Why is it so important to people that this dinosaur would be bipedal ?
blomgren182 Because it would be more accurate, thta question is unrealistic. Why else would anyone care about whether it walked like that or not. qilong.wordpress.com/2014/09/12/the-outlaw-spino-saurus/
+Nicholas Bradley Well we will see when they get 100% of the skeleton. But almost evidence is pointing towards four leg creatures. These guys knows more about paleontology than you and me. I have trust in them and i believe they know what they do. Why do people want to prove them long ? Do people even know how much of the fossil they have ? What the website of serreno and you see how much of the fossil they have, its almost complete.
I disagree with this. If it is true then why did spinosaurus have large claws just to paddle and swim with? I agree spinosaurus most likely are fish and most likely used its jaws to catch fish but it does not make sense to have large claws like it has. To me it is a biped dinosaur not a quadroped! I love spinosaurus
It's jaw was weak and so to tackle things like cocodylomorphs or perhaps whale-sized marine animals, it would need more serious weaponry than those gharial-like jaws. Most likely used it claws for slower, larger prey.
its not semiaquatic its a different kind of crocodile, the hind legs are just says it lived under water, there's no reason to give it lizard like skin and call it semiaquatic
shango thomas Yes. There are some basal cetaceans like _Pakicetus_ and _Ambulocetus_ that can walk on land. Nevertheless, that's not the point I was trying to make. I was explaining how two animals can look similar despite the fact that they aren't related. A _Spinosaurus_ looks like a Crocodilian standing upright, however, _Spinosaurus_ itself is not a crocodile. A whale looks like a fish despite the fact that a whale is a mammal. A bat has wings and can fly despite the fact that it's not a bird. It's called convergent evolution. When two organisms of separate clades follow a similar evolutionary course that makes them appear similar. If you're going to say that _Spinosaurus_ is part of Crocodyliformes just because it looks like a Crocodilian standing up, then you might as well say that a bat is a bird just because it can fly, and that a whale is a fish just because it swims. This argument just as well applies to any animal, terrestrial or aquatic.
I believe that the skeleton the found was already a mature adult. It simply adapted shorter, stronger legs to help it swim and paddle across the water more easily much like a modern day otter. But Spinosaurus was no otter, we're looking at a 15-17 meter long carnivore that preyed on sharks and giant sawfish. Basically anything in the water was at the mercy of Spinosaurus.
Quincy Exactly. This is like the complete opposite of Tyrannosaurus rex. T.rex had long legs and tiny arms whereas Spinosaurus had long powerful arms and short legs.
You people should check out Scott Hartman's blogs about this. And actually read them. The legs here are too short. That's not an opinion, that is what the numbers say.
Even with his corrections its still going to be one ungainly animal and certainly incapable of hunting fast moving prey, it might have used it's legs to find new rivers. I definitely think this veiw of an obligate piscovore actually fits with previous descriptions, don't forget since Baronyx's discovery people have suggested that the Spinosaurs might be quadrupedal. HammerFran Yeah he just scaled an image to fit, that said it's Indeed possible the legs might be a bit longer than Ibrahim and Paul Sereno have estimated but I find it hard to belive they were off by 27% considering Serrno is presumably well versed in Spinosaurian anatomy having created the taxon group itself and having discovered Suchomimus.
It is a very confusing discovery. Because now almost everybody see Spinosaurus as a very weak and Lesser creature. Am ı yhe only one think Spinosaurus could; at least; take short trips on land and has a chance to other theropods? We all know Baryonx did hunt almost every species smaller than itself and İrrirator did all of these too So the spinosaurus is a very weak loser or a winner? Any suggestions ?
***** Crocodiles are the Apex predators of their domain; Prime example is Nile Crocodile and Okonago Crocodile; No Lion Or Leopard even dare to move closer to the animal but if they did they generally hunted down. However since you put it on this way: Please TRY to tell that to The Tyrannosaurus Fan's who write the '' Gay Legs '' , ''SpinoPelicanus'' , '' Daschund Dinosaur'' Rex beat the crap out that thing, This thing is a sole loser .... etc. (Guess these are just starting) I am really Sick and Tired to see every TFan or TTroll write something like this on every documentary on UA-cam However I doubt that Spinosaurus is entirely Aquatic; İt is more like an Amphibious; Adapted to switch between Both Land and Water...
still the argument continues, about spinosaurus being bipedal or a quadruped dinosaur. still it has a possibility of being a chimera and the body proportions do not look clear to me and it is not the 100% of the fossil even the function of sail is a mystery so, literally the mysteries of our beloved spino continues.

This is probably one of the most amusing conversations I've had on the internet.
Man, and I thought Jurassic Park III was accurate. Well, we learn something new every day. This is very interesting!
Humph, now my spinosaurus toy is out of date. News like this is always more fascinating to me than football players getting into trouble with the law.
Jurassic Park Spinosaurus = The Best Spinosaurus and the only one I choose to believe
Brady Barr and Paul Serrano both are good presenters. Both has been my inspiration in making me love paleontology.

It's not the first semi-aquatic dinosaur, penguins exist.

......um... penguin is not a dinosaur idiot
With stubby legs like that, spinosaurus probably lived in the water, only coming ashore to lay eggs.
All the spino lover are now in denial. Still a great Dino that had a no fossils for a long time other than a busted jaw and spines

Huw Brockway Is that the Nova documentary? As far as I know that's actually the most accurate depiction so good choice.
I would like to here more about how it may have walked on all fours.
You didn't see the computer animations in the video? It probably curled up the front arms and walked on the knuckles. If that makes any sense...lol

jurassic park 3 was classical mechanics, this is quantum mechanics.
