Also they calculated on size base on the bones unearthed a couple years ago since the original set was destroyed. Modern species such as crocodiles play a crucial role in how Spinosaurus behave as well.
+Exist Outside The Box More fossil evidence and such. One of the major problems with the more bipedal depictions of Spinosaurus (based on what was known about most other therapod dinosaurs) was that paleontologists couldn't figure out how it didn't topple over, as it was far too front-heavy. The discovery of them possessing a quadrapedal stance solves this problem.
Who is here after the discovery of new spinosaurus tail in morocco?this changes the entire dimension of this discovery. It was primarily an aquatic creature.such a fascinating discovery.I hope eons makes an update on this new discovery
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?
I don't know what Animal Planet is doing these days, but Discovery is a bit of a joke in my opinion. When they began airing all those reality/game shows, that was the end of their credibility.
@@tvbnine793 surprising that out of a 8 ton monster that could crush bones in its mouth like twigs, a fearsome superpredator that lived alongside giant sauropods, and a massive beast of a carnosaur that had sharkilke teeth, the biggest theropod dinosaur of all time was a fish eating swimmy boi with a eel like tail and a crocodile head.
Hi, I'm an arctic archaeologist. But I also love paleoecology. Would you consider doing a video on Megaloceros (the largest deer that ever lived) or Paraceratherium (the largest terrestrial mammal that ever lived)?
From a Rex with a sail, to an armored giant, to a more crocodilian dinosaur. Spinosaurus has changed alot. It was a little odd how this video glossed over the pop culture rendition of Spinosaurus, that swayed scientific thinking until the later discoveries about seven years later. But I must thank you for focusing on the science. Thank you.
pedro henrique gazon My favorite Non Avian is it's "Rival" and it's family. But I can appreciate the crocodilian Spinosaurus. It's odd, but odd is good.
Wait, I didn't caught the thing. What is the answer on that one? Heard recently only about: creating the shadow for fish to eat them like some herons, display and to protect against land predators biting from the up... But none of these seemed to be just the ideal there
@@hoidthings5728 Its tail also had spines. The experts who did the paper have speculated that it would have looked kind of like a newt's tail and been very good for underwater locomotion (but not TOO good, just very good)
I’m seriously in love with the new look of the spinosaurus. It’s so cool and unique now. It’s not just like a regular theropod that hunted other dinosaurs and with similar body build.

Ah Spinosaurus. The dinosaur that in a certain video game can go from walking on all fours and chasing you down in a gait that makes it look like an adorable giant murder puppy, to instead running on its hind legs and clawing at your face in a gait that instead makes it appear like a funny giant death ducky. God I love Spinos.
New Spinosaurus material was found before the Ibrahim/Sereno specimen was discovered, more notable a very large maxilla and a sub-adult specimen in private hand.
Guessed spino would be a swamp monster way back when I heard about it. I remember someone saying the sail would break easy and kill the animal if it ran around like Trex is said to. Glad a better perspective came about
Man, what I would give to see that river of giants in its prime. I can't even imagine how awe inspiring and terrifying it would have looked and sounded.
Mine too, it's in my top 5 of favourite dinosaurs. I know it when I saw Jurassic Park 3 in theaters, and it's a fascinating animal. And the reconstructions didn't make it worse, it's even more incredible. I was really excited with the discover of his new tale and the theory of a full aquatic animal. But my most favourite one it will be always the Deinonychus.
And now the sail just gets longer to the tail. It's so exquisitely exciting to keep following the update of Spinosaur through lifetime. It seems the mystery is slowly yet surely to be unraveled.

My five-year-old daughter and I *love* your videos. We were wondering about the differences between frogs and toads. When did they evolutionarily diverge?
I think it would make sense that the sail, while the rest of the body was submerged, would help to regulate body temperature, and probably doubled as a display for mating. To have all these adaptations for life in water, I'd say it's quite obvious that they spent MOST of their time in water, not just some.

Its upper body anatomy and arm anatomy would not have allowed for it, it may have had shorter legs than previously thought but that does not mean it would have slumped over on to its arms, even though it was a light animal for its size its arms could still have not bore the weight with out breaking in some kind of way. (also did not mean to sound aggressive, was just passing on information)
it was a predominant aquatic predator, thats why it had aquatic adaptations.... The animals that it ate was around or in the water. The fish that it hunted were larger than some smaller boats. upload.wikimedia.org/wikipedia/commons/7/75/Spinosaurus_with_contemporaneous_taxa.jpg
"The River of Giants" was only part of the Kem Kem beds, Bahariva was a own river sytstem and there were a couple other rivers flowing into the sea in North Africa, it wasn't one giant river ;)
The modern Goliath Frog is almost as big as 40cm Beelzebufo. There's evidence of an even bigger prehistoric giant helmet frog 50-60 cm in length (can't link to scientific article because YT marks it as spam)
Sean Dewar The article is called "Evidence of a giant helmeted frog (Australobatrachia, Calyptocephalellidae) from Eocene levels of the Magallanes Basin, southernmost Chile" To be more precise: The estimated length of it is 580- 591 millimetres
Spinosaurus was and is my favorite dinosaur growing up. Even though it may not look like it could take on a T. rex like in Jurassic park 3 it still looks badass as this is what it truly looked like and I’m happy to except the truth. It’s just like if dinosaurs had more proto feathers than we thought they are still cool and only true lovers of history will be able to except this.
The literal translation would be "free lord" or "free master". A "Herr" is a man with a certain autority over other people. Although today "Herr" is the general polite form of adress for any man in German, similar to using "Mister" (from "master") in English. "Freiherr" is the lowest nobility title, equal to "baron" in French.
i’ve watched this video so many times! the spinosaurus is my favorite dinosaur ever and also my favorite animal. thank you for this video it really has given me so much info on the coolest dino ever!!
Please do a video about how the ancestors of vertebrates and arthropods separated! I'd love to see what science knows about why and how such different solutions to limbed life came into being, and what adaptations occured in the cleavage point. :D
U guys forgot to mention about Scott Hartman’s reconstruction because the one you showed in the video is classed as inaccurate because the legs are 28% smaller than what they should be, but it was really enjoyable and I love hearing about its history during ww2 u guys r awesome so keep popping out these dinosaur videos
Hartman only disagreed, he didn't prove that Ibrahims proportions are wrong, in fact Ibrahims team corrected Hartman on his reconstruction later on....
Since blood is a very ancient trait found in almost all animals a lot about it is unknown, but theorizing about why and how it evolved would still be cool.
A video about a census of prehistoric fossils found that estimates populations of various now extinct species would be cool. I know you have noted the overwhelming numbers of trilobyte fossils found, would be cool to see how other fossils stack up population/numbers wise too.
+Mohammed Alassaf this video is *not* really 'that' accurate anymore Turns out that the Spinosaurus is more like the theropods, terrestrial dwelling. The Spinosaurus seem to be really unfit to diving; and not even swimming due to its anatomical structure, and placements of its organs, along with the fact that the *original* bio-isotope studies concluded that the spinosaurus is the most terrestrial spinosaurid and has similiar isotope compared to most theropods. Sources; Oxygen isotope evidence for semi-aquatic habits among spinosaurid theropods A buoyancy, balance and stability challenge to the hypothesis of a semi-aquatic Spinosaurus Stromer, 1915
@@thedoruk6324 Since Im too lazy to go see it myself: Does the Spinosaurus stick part of its head into the water to catch prey? That has to be the use of the receptors and the raised nostrils
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.
Ok, this has been driving me crazy forever: if Spinosaurus was a quadruped, how did it place it's hands? Dinos couldn't rotate their hands (google "clappers not slappers") so they couldn't walk on their palms if the fingers pointed forward. Did they walk on their knuckles with their claws curled inward, the sides of their hands (think army-crawling), or what? I'm a game designer professionally and I've been wanting to make a mod for a dino game that uses Spinosaurus but I can't find a straight answer anywhere.
Infernoraptor from what I've read yes most paleontologist seem to agree that Spinosaurus walked on it's knukles. But sometimes you won't find a straight answer to this things and the truth is alot more complicated than yes or no.
Gandalf the Tsaagan You say that and now I'm envisioning a (unrealistic, i know) galloping spinosaur. I didn't know about the wishbone thing. Does that mean that theropod arms couldn't be positioned at different angles (EG: could they walk like an egyptian)?
It had short legs, but it wasn't a knuckle walker. It still wasn't as tall as T-Rex, but longer. If it was Quadrupedal It's knuckles and wrists would break under it's weight
I love this stuff. You guys are the only consistent source of prehistoric content on RUclips. Also, you should do a video on the history of Carnotaurini.
What an interesting history of my fave Dino! I'm curious, when was spinosaurus's "posture" updated from standing to all fours? Surely that original model didn't last too long?
First, the pin's you wear on your shirts in the episodes you host are so cool! Second, why does war seem to draw upon the destruction of priceless relics? Such a shame.
There IS fossils of other semi-aquatic dinosaurs: Hesperoronis, Polarornis and a lot of other cretaceous semi-aquatic birds. And if you dont want birds, there is also Halszkaraptor... And I dont even mention any semi-aquatic birds after KT extinction.
I'd love to see a video about evolution of mammals. Did the monotremes come first? How did we end up with marsupials? Have we found any evidence of early placental mammals? How did we get from Dimetrodon to tiny rodent-like stem mammals?
Just spitballing here: Is it possible that Spinosaurus hunted by remaining stationary in the water, with most of it's body underwater? In which case, could the spine/sail have been there to keep it warm (majority of body in cold water, sail out of water catching sun's rays) while it remained still, waiting to ambush it's prey?
It's still debated weather spinosaurous had back legs that were similar length to the front ones or if they were a lot longer because the newer bones were found from a juvenile spino while the older ones were probably from an adult one. Another thing they noticed is that if the 2014 model was actually how it looked then it would have to be quadrapedle when walking on land, which would be really hard on it's wrist bones and front claws
The hindlimbs found were of a sub-adult. But what you have to undertstand is that even for a sub-adult it's legs were proportionally very short and nothing like other terrestial theropods. It had short hindlimbs. And multiple paleontologists have proven that it could indeed walk on it's proportionally short hindlimbs like andrea cau.
What about big sea dinosaurs or something similar? I don't really know what that big thing is in Jurassic World, the one underwater but I found it both fascinating and terrifying. It actually became my favorite since I love fishes and underwater creatures. So it'd be great to know more of those kinds of things from back then and whatever period they came from.
I love these videos. It's just so relaxing to know about these things. One thing that I would like to know about, insects. What were insects like back then? Were there giant mosquitoes/flies? Huge maggots?
Suchomimas and Baryonyx were both mentioned in Jurassic Park 3 as candidates for the giant that attacked the plane before Alan determined it was a Spinosaurus
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.
Wait a minute.. so any depiction of spinosaurus that I've seen before 2014 was based on pictures of a few bones? That's actually quite impressive!
LEGOSAURUS how did they figure out the arms is what I really want you know
Exist Outside The Box
They probably used Spinosaurus' relatives as a reference
Also they calculated on size base on the bones unearthed a couple years ago since the original set was destroyed. Modern species such as crocodiles play a crucial role in how Spinosaurus behave as well.

Well, I did more than 60 pieces of art or a upcoming book on the subject, one learns a few things here and there ;)
Bless you
I know this is late, but is the book out? What is it called? Id like to check it out!
So if I'm not mistaken, Jurassic Park 3 depicted Spinosaurus in 2001 but we really didn't have much to go on until 2014?
Yup
2020 spinosaurus: ight, watch this
Yay my favorite Dinosaur
Can you do a Video of Beelzebufo?
Would be interesting to learn more about the Madagascan frog from hell
YES!
The modern Goliath Frog is almost as big as 40cm Beelzebufo. There's evidence of an even bigger prehistoric giant helmet frog 50-60 cm in length (can't link to scientific article because YT marks it as spam)
Superdumpfback do you know the Scientific name of the Frog or the name of the Article so I can going it myself?
Sean Dewar The article is called "Evidence of a giant helmeted frog (Australobatrachia, Calyptocephalellidae) from Eocene levels of the Magallanes Basin, southernmost Chile"
To be more precise: The estimated length of it is 580- 591 millimetres
i'd love to see a new video about the tail discovery! spinosaurus is so fascinating
*Spinosaurus was a semi-aquatic dinosaur*
My brain: HE’S A SEMI-AQUATIC, EGG-LAYING REPTILE OF ACTION!!!!
This Chanel is we’re Ark players come to make reference.
Kinda yh
Can I just express how awesome it is that someone named a race of dinosaurs Irritator? Awesome. Thank you.
Spinosaurus was and is my favorite dinosaur growing up. Even though it may not look like it could take on a T. rex like in Jurassic park 3 it still looks badass as this is what it truly looked like and I’m happy to except the truth. It’s just like if dinosaurs had more proto feathers than we thought they are still cool and only true lovers of history will be able to except this.
His name began with Freiherr, that's an old nobility title. ;)
Freiherr=Freeman in German?
The literal translation would be "free lord" or "free master". A "Herr" is a man with a certain autority over other people. Although today "Herr" is the general polite form of adress for any man in German, similar to using "Mister" (from "master") in English.
"Freiherr" is the lowest nobility title, equal to "baron" in French.
Fun fact: Stromer's full name was "Karl Heinrich Ernst Freiherr Stromer von Reichenbach".
@@johannageisel5390 aber den titel baron hatten wir dich auch ^^

I've never been so happy. This is my favorite dinosaur and has been since i was a kid. Thank you guys so much!!
Someone called spinosaurus a “useless fish eater” and I asked them if they’d call a Nile crocodile that while staring it in the face. No response.
It is very telling about how rare fossils really are since it took a century to find another example of spinosaurus.
Darn that WW2, so much fossiles lost :( great video !
De Boswachter well carpet bombing tends to be indiscriminate...
And People too
The allies were the real war criminals
Probably my biggest gripe about the wars, though they were silly to begin with.
Brandon Smith yeah idk bout that son.
I've watched all your videos in less than three days. They're all great, keep up the good work :D
CybranM You are not the only one. I did it in one week.
Do any stand out as favorites, or like Top 10 material? And kudos. I love finding a new channel to love and just breathing in the content.
I literally just finished presenting my 10th Grade Project. My chosen topic was the Spinosaurus' sail. It is my favorite dinosaur.
i’ve watched this video so many times! the spinosaurus is my favorite dinosaur ever and also my favorite animal. thank you for this video it really has given me so much info on the coolest dino ever!!
+awwardemo this video is really not accurate anymore
Good job Jurassic park 3 your spino was surprisingly accurate for what you had to work with
Please do a video about how the ancestors of vertebrates and arthropods separated! I'd love to see what science knows about why and how such different solutions to limbed life came into being, and what adaptations occured in the cleavage point. :D
U guys forgot to mention about Scott Hartman’s reconstruction because the one you showed in the video is classed as inaccurate because the legs are 28% smaller than what they should be, but it was really enjoyable and I love hearing about its history during ww2 u guys r awesome so keep popping out these dinosaur videos
Hartman only disagreed, he didn't prove that Ibrahims proportions are wrong, in fact Ibrahims team corrected Hartman on his reconstruction later on....
Could you cover the evolution of blood?
Since blood is a very ancient trait found in almost all animals a lot about it is unknown, but theorizing about why and how it evolved would still be cool.
They did look it up
I'd love to see a video dedicated to the T-Rex. Also, one dedicated to what aquatic life was like during the Mezozoic.
A video about a census of prehistoric fossils found that estimates populations of various now extinct species would be cool. I know you have noted the overwhelming numbers of trilobyte fossils found, would be cool to see how other fossils stack up population/numbers wise too.
2:02 so, basically stromer discovered godzilla..
+Mohammed Alassaf this video is *not* really 'that' accurate anymore
Turns out that the Spinosaurus is more like the theropods, terrestrial dwelling.
The Spinosaurus seem to be really unfit to diving; and not even swimming due to its anatomical structure, and placements of its organs, along with the fact that the *original* bio-isotope studies concluded that the spinosaurus is the most terrestrial spinosaurid and has similiar isotope compared to most theropods.
Sources; Oxygen isotope evidence for semi-aquatic habits among spinosaurid theropods
A buoyancy, balance and stability challenge to the hypothesis of a semi-aquatic Spinosaurus Stromer, 1915
Yep
Yep uhhhhhhhhhh wow
@@thedoruk6324 Since Im too lazy to go see it myself: Does the Spinosaurus stick part of its head into the water to catch prey? That has to be the use of the receptors and the raised nostrils
Croczilla
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.
Scientists: We think we know how this dino looks
Spinosaurus: Hold my drink
The Spinasaurus has always been my favorite Dinosaur
This was great. I want more episodes like this, that focus on the actual discovery and fossils.
Ok, this has been driving me crazy forever: if Spinosaurus was a quadruped, how did it place it's hands? Dinos couldn't rotate their hands (google "clappers not slappers") so they couldn't walk on their palms if the fingers pointed forward. Did they walk on their knuckles with their claws curled inward, the sides of their hands (think army-crawling), or what?
I'm a game designer professionally and I've been wanting to make a mod for a dino game that uses Spinosaurus but I can't find a straight answer anywhere.
Infernoraptor from what I've read yes most paleontologist seem to agree that Spinosaurus walked on it's knukles. But sometimes you won't find a straight answer to this things and the truth is alot more complicated than yes or no.
The quadruped thing has been debunked for a while now, it's more commonly accepted that it just had stubby legs and a longer tail
Gandalf the Tsaagan You say that and now I'm envisioning a (unrealistic, i know) galloping spinosaur. I didn't know about the wishbone thing. Does that mean that theropod arms couldn't be positioned at different angles (EG: could they walk like an egyptian)?
It had short legs, but it wasn't a knuckle walker. It still wasn't as tall as T-Rex, but longer. If it was Quadrupedal It's knuckles and wrists would break under it's weight
I love this stuff. You guys are the only consistent source of prehistoric content on RUclips. Also, you should do a video on the history of Carnotaurini.
It's not so much the sail, it's the dent in the upper jaw of the Spinosauridae - a trait they all share - that baffles me
Would you compare the jaws of spinosaurids to crocodilian jaws?
This is why it's my favorite dinosaur.
The sail might have been used to capture sunlight's heat while it waded the waters at shoulder level depth
What an interesting history of my fave Dino! I'm curious, when was spinosaurus's "posture" updated from standing to all fours? Surely that original model didn't last too long?
First, the pin's you wear on your shirts in the episodes you host are so cool!
Second, why does war seem to draw upon the destruction of priceless relics?
Such a shame.
There IS fossils of other semi-aquatic dinosaurs: Hesperoronis, Polarornis and a lot of other cretaceous semi-aquatic birds. And if you dont want birds, there is also Halszkaraptor... And I dont even mention any semi-aquatic birds after KT extinction.
Im proud of Spinosaurus being my favourite dinosaur.
"The World's only Semi-Aquatic dinosaur"
Halszkaraptor: I'm about to end this man's whole career
I'd love to see a video about evolution of mammals. Did the monotremes come first? How did we end up with marsupials? Have we found any evidence of early placental mammals? How did we get from Dimetrodon to tiny rodent-like stem mammals?
Just spitballing here: Is it possible that Spinosaurus hunted by remaining stationary in the water, with most of it's body underwater? In which case, could the spine/sail have been there to keep it warm (majority of body in cold water, sail out of water catching sun's rays) while it remained still, waiting to ambush it's prey?
It's still debated weather spinosaurous had back legs that were similar length to the front ones or if they were a lot longer because the newer bones were found from a juvenile spino while the older ones were probably from an adult one. Another thing they noticed is that if the 2014 model was actually how it looked then it would have to be quadrapedle when walking on land, which would be really hard on it's wrist bones and front claws
+TimeyWimeyStuff precisely. İbrahim exagratted
The hindlimbs found were of a sub-adult. But what you have to undertstand is that even for a sub-adult it's legs were proportionally very short and nothing like other terrestial theropods. It had short hindlimbs.
And multiple paleontologists have proven that it could indeed walk on it's proportionally short hindlimbs like andrea cau.
That's why I love Spinosaurs they're so adaptable in land and water.
Watching history video (like dinos, ice age, very old history, like not ww2 and civil wars) give me such a good vibe.
What about big sea dinosaurs or something similar? I don't really know what that big thing is in Jurassic World, the one underwater but I found it both fascinating and terrifying. It actually became my favorite since I love fishes and underwater creatures. So it'd be great to know more of those kinds of things from back then and whatever period they came from.
3:27 Fun fact:
They named that dinosaur Irritator because they had a hard time finding out what it was! Very irritating...
I love these videos. It's just so relaxing to know about these things. One thing that I would like to know about, insects. What were insects like back then? Were there giant mosquitoes/flies? Huge maggots?
Suchomimas and Baryonyx were both mentioned in Jurassic Park 3 as candidates for the giant that attacked the plane before Alan determined it was a Spinosaurus
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.
