Spinosaurus: The Scariest Carnivorous Dinosaur to Have Ever Lived | Dinosaur Documentary 

My favorite dinosaur

Spinosaurus...whether it was a fish eater, sub aquatic or whatever new research they discovered about it...its still a fascinating Dinosaur!

Spinosaurus is a damn fascinating beast of ancient times.....it gives me visuals of massive river systems stalked by these ancient titans, their conflicts with ancient large crocodiles (how would that go down I wonder), and the abundance of ocean life with all kinds of fish and sharks preyed on by Spinosaurus. I wish I could truly see what their world was like between water and land.

Ah, yes, Spinosaurus. Given the rate of scholarly opinions about its lifestyle shifting with every publication, I can't wait for this video to be outdated this time next year.

Ah the Spinosaurus, one of the most debated Dinos, but still one of the bests.💚 I just personally love the look despite how much it’s debated.

I'm still of the opinion, that the Spinosaurus' Sail was, at least partially, for heat regulation. I mean, it doesn't necessarily matter, if it was just semi aquatic or spent large quantities of time in or under water, water tends to absorb your body heat and cooling you down, so it would be just really practical to just stick your back sail into the sun while floating or swimming at the surface to quickly heat your body back up once you start to get a bit chilly. Also, it could've used its Sail as a form of stabilizer, or whatever job the back fins of most fish, whales and dolphins serve.

Everyone loves a mystery, and this dinosaur has it all. Its true mystic power is how rare and fragmentary these fossils are in the geological record. I have many fossils from Tyrannosaurus rex and Spinosaurus, and the Spinosaurus bones hold my interest in regarding further study the most. They are extremely dense in cellular structure and difficult to find. Teeth are common but frequently confused with contemporary mid Cretaceous crocodiles found in the same sediments. Having lost the original Egyptian specimens make this animals fossils even more interesting. Fortunately, I have been in association with friends with several paleontology specialists who have directly collected specimens in Morocco. This allowed me to work on several important specimens, and I regard these fossils as my favorite work. Many collectors around Europe and North America have obtained these fossils online from Morocco. If you're one of these individuals, please share your knowledge with other collectors and paleontologists to continue this saga.

Palaeontologists: Why can you just be normal?! Spinosaurus: *REEEEEEEEEEE*

I got a Spino tooth for Christmas, and was super excited and felt so special, but turns out they are super common.

Every time I water ski in a lake that is murky enough that I can't see my feet, THIS, or something like it, is swimming right below me. I can totally feel it brushing my toes! 😂

This is such great scientific history, well told. I was really carried along by the story. Great work as always!

There's always been a special place in my curiosity for spinosaurus. It's a cross between really cool, and really nightmarish.

"Picture this: you're a fish..." I see right off the bat I'm gonna need a joint for this.

Excellent information on what is now known (precious little) on the Spinosaurus. I had no knowledge of them. I look forward to following this debate and see what happens.

Great upload as always. And a good drama in the paleo world:)

Did I just see my artwork of Spino. aegypticus and Spino. maroccanus in this documentary? I honestly have no words or that someone actually like it to put it in this video

Wow. Really nice video. Very nuanced. Thank you so much ❤

Hi. Amazing video. Thank you very much. Regards Chris

Spinosaurs were awesome

Thank you for the great information and your excellent presentation! 🐸

Thank you! Can't wait to learn more about the spinosaurau s and all dinosaur 🦖 love it!

Some people are just too rigid in their ideas and beliefs. Just thinking about how other animals function and some common sense can probably reconstruct the Spinosaurus until we have a more complete skeleton. Spinosaurus was probably at least a decent, if not good, swimmer based on the recent tail bones discovered. Its sail was probably both heat regulation and display, if not also helpful when swimming or for balance in some way(idk, seems like it could be). The Spinosaurus likely walked on all 4 legs most of the time but could also walk on just hind legs for a shorter period of time. This would allow it to actually use its claws in combat or to catch and tear open prey. It seems like the Spinosaurus was an ambush predator in the water, whether while it was swimming or just wading. Thats how I believe you'd get a more accurate reconstruction of the Spinosaurus with the fossils people have found. Who knows for sure though. 🤷🏼‍♂️

Sail more likely used to regulate air for this aquatic land situated animal. Like birds, the spines may have help move or rotate it's ribs to expel oxygen in different swimming or feeding processes.-Donna Carland

Very detailed video.i will not forget this creature....im catching up on what i didn't learn at school.

I feel bad for anyone who puts out some Spinosaurus info. They're like, the Shroedinger's Informations - both new and obsolete at the same time.

Thank you for sharing this information about this dinosaur. It is interesting the controversy about ots abilities.

Well made and rather factual ! BRAVO ! 🙏 ... but, the 'tail' of Spiny has been "ridden" and "reridden" . . . 😳

A friend made me download path of titans. I was never really interested in dinosaurs, but the game woke my interest. Thanks for the video. Spinos are bad ass.

I think the debates will keep going on and on only until more complete fossil skeletons are found. Personally, there’s something about the latest reconstructed skeleton that just doesn’t feel right, it is a reconstruction made of bone fragments found in different location, size and time period, as well as fragments of other theropod species, there are just too many missing links in it, if you look at the reconstructed image it just doesn’t look natural, especially the proportion of body, limb and tail.. it shows a bizarre looking creature that can hardly walk on land or swim well in water. But I understand this is the best version they can create basing on the latest evidence available. Hopefully there are more complete skeletons to be found so that they can create a most realistic image of spinosaurus

Such a beautiful majestic Dino along with T-Rex and Ankylosaurus ❤️

16:42 Debate topic 2 The sail? I have toyed around in my mind about what exactly was the function of the sail? I assumed it was to create a big shadow in the water that fish would gather around and The Spinosaurus would stalk its prey from the side on angle, having a crocodilian head would make this ideal for the ambush set up near the bank of the river/lake.

Really really good, thank you

Very interesting video and all the best for the new year with your channel

great overview of the Spinosaurus debate

Thank you for amazing film. Also I love your voice, it’s magical specially for sleeping 😂 believe me 😅several times I fell asleep during watching your videos despite of all my attention to the film, because of your calm and peaceful amazing voice I don’t remember when and how but I slept and only woke up again when the video was ended and I disturbed by ads 😊👍🏻

Those of us who have owned a 6 foot adult Iguana and taken it down to the clear tidepools at the coast know exactly how the Spinosaurus swam and how fast. The hip and shoulder joints aren't the same but the rest is a scale model of your dino. They even have small spines. My primary advice is to add far more stored fat to the base of the tail to balance the front of the animal as Iguanas do. And yes, Iguanas can and do run on only their hind legs using their tail as a counter balance weight.

2:25 lol what is this video from? The groundskeeper from Caddyshack is casually brushing off a human skull in the desert

My favourite dinosaur

I love the inclusion of images from Ark: Survival Evolved. Took me a second to recognize it.

That is a really neat dinosaur.

This particular narrator has been on several you-tube videos and his voice drives me absolutely insane.

thank you ..top job ..

Such a nice video to watch

*"The Scariest Carnivorous Dinosaur to Have Ever Lived"* Never understood why to be honest and this video does little to explain that. I find these animals fascinating like all animals during the Mesozoic. I do not think it was the scariest, I'd find being hunted by a group of Utahraptors scarier

Sails on the back don’t necessarily slow you down. The Sailfish are one of the fastest in the ocean and they have a huge fin/sail.

Interesting video happy new year to all

Shame he didnt mentioned the pressure receptores in the tip of Spinosaurus snout. It's basically the same as on crocedile snouts. Still a very good video

I like your voice, it is so relaxing

very good job video

very pleased to know this was a REAL dinosaur. For some reason, I thought it was made up for JP3

I would say that the Spinosaur is the Cayman from hell. The thing that gets me though. is that the anthropologists have overlooked the "lay-down" function of the dorsal spines...They most likely laid down in a duplex manner, were the dorsal bone laid down in a left right left right manner allowing the fin to flatten out into a configuration that resembled a flat topped double edged carapace shape. Maybe we should be paying attention to the fin configuration before we start saying it was a lousy swimmer?

Low efficiency tail ? It's tail looks exactly like those of Tritons, excellent swimmers, check it out

We do know it walked on two legs precisely because its hand bones couldn't possibly support knuckle-walking; it could do it a total of *once*, and then its hands would break, and that really does remove its ability to hunt. It therefore was strictly bipedal.

I can really imagine the Spinosaurus to be an semiaquatic animal like a crocodile. Besides swimming through the water to catch prey like fish, it could also use a crocodile's hunting technic: Waiting near the shore, standing still to blend in. The neural spines could be used - 1. as camouflage to pretent to be a rock and / or 2. In a similar way a dolphin uses it's dorsal fin for stabilizing and / or 3. to feel movement in the water. It would wait for long times that another animal would come close and then it would attack the pray.

Biggest? Sorry no T-rex weighs more than spinosaurus weighs. Spinosaurus is listed as weighing 7.5 to 9 tons. There is an unpublished paper that claims 12 to 19 tons but because its an unpublished paper it must be ignored. TRex initially was thought to weigh up to 8 tons but new papers cite TRex weighing up to 15 tons. The 8 ton aspect comes from remains such as Sue that weighed in around 9 tons, but new studies believe 20% of TRexs were larger than Sue and Scotty which is the largest found at over 9 1/2 tons.

"You're a fish in the late Cretaceous" - There's a turn up for the books

This is so cool!

with the opening and with your voice, you could've been a hypnotherapist, but you chose violence! :P

So much to think about. I imagine them walking similar to kangaroos, using the much shorter front legs when not in a hurry. I think they would have ran on two legs. I have always pictured them as being at home in the water, adequate swimmers. Fish sleep, they don't have to be fast. It could be all in timing. If they want to compare them to crocodiles, why not also compare them to alligators, which walk up high and can run as well as climb chain link fences.

The thing with Jurassic Park dinosaurs, that seemingly most people forget, is, that they're *_all_* mutants. None of them is a straight up dinosaur that lived in the past, because they only ever found fragmentary DNA of them, and filled up the gaps with DNA from modern day animals that are, or that they thought to be, related to dinosaurs, like lizards or frogs. That's why Things from the books or movies contradicting what Scientists found still work. The movie said, that T-Rex could only see movement, while Scientists say that it most likely had exceptionally good eye sight, and there is this big Argument ever since. But guess what? The movies depiction of a T-Rex that can only see movement is still valid, because they spliced in frog DNA to fill the gaps in the genetic code, and many species of frogs indeed have movement based sight.

You have such beautiful voice.

Spino was the otter of its time with the size of a t-rex

Though, I have to admit: if you want a solid image for a Spinosaurus: think a penguin that's increased to whale-sized, with a general anatomy of a large theropod and you *probably* have a solid image of the animal in question in your mind when you do that.

Great informative video! But the backing music is obnoxious. The pterosaur video was ruined by the same music, and I really wanted to enjoy that one as well ☹

No that title goes to the T Rex.

The vertebrate specialist was interested in the spinosaurus! 😅

Rexy was still number one ;)

I think the spinosaurus' sail is a retractable sail. Since it looks much like the sail of a sailfish, the spinosaurus could have used its sail to corral fish, or lay the sail down so it could swim faster.

Spinosaurus Aegyptiacus!! My favorite G.O.A.T dinosaur!! 😎👍🏼

Is it safe to say that you would not want Spinosaurus looking at you or even within a hundred yards of you.....ever! What a beast! That is meant as a compliment to its terrifying nature.

As a palaeontologist in training studying spinosaurus and other member of spinosauridae I’ll fact check this! 1:42 S. maroccanus is considered a dubious name as we believe the holotype species (S. aegyptiacus) to be the same as the neotype species (S. marccanus) and so there is only one Spinosaurus species considered valid. I like how he is actually showing the history of the discovery of spinosaurus not just the creature itself. 9:21 spinosauridae is a family not a group but it’s a minor detail. 9:50 a great piece of evidence for a fully aquatic spinosaurus 15:12 larger but not more massive (due to current estimates 16:30 more recent estimates put it at 7 tons 17:43 as surprising as it may sound this is actually accurate. Although the hump less so. Also you are directly reading off what the first search option says; www.livescience.com/24120-spinosaurus.html And I have to say… it’s not very accurate. So I wouldn’t use this site for information. 38:15 no. As seen in that diagram the centre of mass was likely just infront of the back legs. almost exactly the same as every other therapod and so it would have had no issue holding itself on its hind legs. Also it’s a very big step to go from a bipedal to a quadruple stance and it would be the only known therapod dinosaur to do so if that was true. So no. Spinosaurus is NOT quadrupedal as of our current knowledge.

Great video, but please reduce the bass in your mixer, it's overwhelming and hard to hear your voice on systems with good audio quality

I love how the video said that things could be outdated in 10 years time. More research and discoveries to come on this fascinating dinosaur. My favorite dinosaur! My only critique is the way the spine connects to the tail. Instead of being symmetrical, it has that v-shaped wedge. I don't really like that design.

The most awesome dinosaur.

For me Spino was a semi aquatic animal who primarily was hunting fish but I think similar to crocodiles also a lurking hunter that possibly could have attacked smaler dinos.In the water he was with this feets comparable to modern birds and with that tail to a row of water lizards.Also its long neck is reminds to many semi-aquatic birds that van swiming on the surface but also dive into the depths.The claws of the Spino could be used to hook up prey but also for defense.I think Spino were a high specialized dino that lived between land and water but mainly into water or swamps.That dino had found irs own very specialized corner and it was for a long time successfully.But as landscapes changed Spino died out because of its specialization and the lack of time to adaptation to new circumstances.

My most recent thought is that if it was semi-aquatic, the sail could have cast a big enough sail to cast shade, similar to that of a black heron with its wings? Could have been a sit and wait predator?

In many ways the Spinosaurus mode of operations is suggestive of today's crocodiles: good swimmers, combining ambush predator skills with scavenging habits. We don't know whether Spinosaurus was hot blooded or reptilian so it's a guess whether the "sail-like" physiology was used to sun-bask absorbing heat & regulating temperature in deeper colder waters where fish may have been more abundant.

i think there are plenty of apex predators that are scarier than the spino simply because its hunting ability is worse than say a giga or rex or allo or any other land based theropod

built like a garial . It was aquatic a top fin like a fish along with that giant flat tail excellent swimmer . It was a fisher

Is the CGI underwater, swimming footage from a different documentary? If so, I'd love to know the documentary it came from.

I really like dinosaurs

From India ocean walk often comes Dinos across the ocean searching after breeding mates. Iguandons are good.

Crazy looking creature. Definitely a crocodile like tail but sue wasn’t an ambush Hunter with a sail on its back. I think it spent a lot of time on the water. It just has a croc look. It just didn’t come from the croc linage. Aquatic dinosaur and convergent evolution? Maybe. Did this creature have its niche or was it heading to one,

This animal used it's sail to warm up before the other animals. As the other animals were on the beach trying to warm up , the spiner was already warmed up and could attack the sluggish animals not up to escape temperature.

I used to work out at the boxing gym. I bet I could knock out a velociraptor with a left-right-uppercut combination.

Spinosaurus 🔛🔝

something i think people need to do is stop complaining about inaccuracies within the jurassic park franchise. not only is it just a movie, it's confirmed a lot of the mutations and differences made in the "modern day" dinosaurs were caused by the modern reptile dna put into the dino genes to fill the gaps. thus why a lot still do not have feathers, this was a fixed issue in the newest movie as the pyroraptor and the therizinosaurus have feathers possibly because they started to use modern bird dna to fill in gaps! ON TOP of that a lot of the mutations were man made without the "help" of the modern reptile or bird dna. they modified them to make them scarier/cooler because they were meant to be amusement park attractions !! so people complaining about the inaccuracies is something that has always been a pet peeve of mine because all the answers to those inaccuracies are laid out in front of them within the movie !! of course there is more to this considering dinosaurs are changing every day due to new discoveries but for the sake of the movies the answers are right there

For those kastrations by Dinosauer breeding we can just gratulate the old mans.

It wasnt the bite that broke the rex neck in the movie if you watch the spino used its arms the do the job

I have two spinosaurus fossils. One adult tooth and one baby tooth.

You know, l’ve often imagined myself as a fish in the late Cretaceous period.

Spinosaurus marrocanus was considered invalid years ago. Whether or not the Moroccan specimens are a different species is still under debate.

My favorite dinosaur because of how strange they are and they're just simply cool looking! 😎

You mentioned that spino teeth were comparable to crocodiles and turtles but turtles don’t have teeth. They have dental-like structures called papillae inside their mouths and throats, and also have hard, sharp edges around their beaks. If not a mistake/misunderstanding on your part - which is okay, it happens - then I wonder what the people behind the study meant?

Thing about the Spino is it killing a rex coukd've been realistic. Definately not as easy as seen in the movie but for what we know the Spino was the apex of the land and water of its region which even humans cant necessarily claim. Larger, heavier, stronger, faster, more agile, most certainly smarter (due to their largely fish diet) and quite possible more durable due to it's quadrapedal status. In fact this branch of the family tree, stem mammals, is the branch of life that would ultimately "evolve" away from being reptiles and into mallas. Hence the term" mammal-like-reptiles." While I understand the Spinosaur and some other dinosaurs ended up having its own term "Spinosaurids" they were really just "Large stem mammals." Having the same evolutionary traits for largely the same reason just being too large to classify as such.

Whilst T-Rex has the strongest bite force of anything we know of. Spinosaurus's largest specimen NHMUK VP R-16421 is bigger than Scotty, the largest T-Rex specimen. We also have to account for Spinosaurus's tail; the largest for any theropod we know of. As well as its arms which only Therizinosaurus, which isn't carnivorous, even compares to. That's also not accounting for the fact that we know Spinosaurus could fight and potentially kill a Carcharodontosaurus with its bite, given the private collection specimen that has Spinosaurus teeth in a Carcharodontosaurus's vertebrae.

My favorite badass dinosaur

Scariest? Nah.. Weirdest? Nah... would it beat a T-rex? Naahhh... is it the coolest one? Possibly! Top 3 at least
