- Giant theropod, large sail, big bulky arms with giant claws, and is always debated about? Sounds like Spinosaurus right? WRONG! This is Oxalaia, the Spino's Brazilian Twin.

Man spinosaur fossils have bad luck not being destroyed in museums
Thank the german thieves
no kidding! Almost like a deity is seeking to make sure this secret will always remain in doubt
Brazilians Lost both Fossils of Irritator and Oxalaia. Oxalaia was destroyed, and Irritator was stolen by Germans.
ALIENS
Not getting destroyed in Museum Challenge: Impossible
bro, they found two bones and were like: Yup it was a master fisherman, had a bite force 20x that of a wolf, went to college in 1982, and had a crush on his gym teacher.
LOL😂
humm not buying the 20x bite force, how could they possibly know!
Wait til you find out about Quetzalcoatlus
I'm not a palentologist or biologist, but I think it's reasonable to say that bite force is one of the ONLY things you CAN infer from just jaw fragments...
@@IllustriousCrocoduck yeah but we're fooling around ;)
It is kind of ironic, that even their finding history is simmilar. Both got their only fossils destroyed shortly after discovering, due to destruction of the museum they were held in.
True, the original fossils were both destroyed. But because of the original spino fossils destroyed it intrigued people to go find a full skeleton. This is how researchers found out more about spino as their was a whole market where it's fossils were being sold and finally a almost complete fossil found in morroco.
@@Robert53area amazing
It's almost like a curse because the whole reason why Irritator challengeri was given its name was because of the frustration the founders went through of its discovery.
I find that suspicious
If I had a nickel for every time spinosaur fossils stored in a museum were destroyed, I’d have two nickels. Which isn’t a lot, but it’s weird that it happened twice, right?
Lightning never strikes the same place twice... Unless you are the fossilized remains of a Spinosaurid.

That can also be a kind of light.
But when asking for some light you probably don't want an incendiary bomb or a Molotov thrown at you. 😁

Spinosaurid fossils try not to be destroyed challenge difficulty:IMPOSSIBLE
Edit:THE AMOUNT OF LIKES
Damn planes going bombs away
The moral of the story is don't keep spinosaurid remains in your museum. This one caught fire, the Allies bombed Egyptius', are there any other instances of this?

Spinosaurus: Hey twin!!
Oxalaia: Yoo! 🤝🙏🤞
Tragically analogous that Spinosaurus for the longest time was also known from very little fossil evidence. The holotype was destroyed by allied bombing during WW2. Wasn't until Paul Sereno much, much later that we got a better idea of what Spinosaurus was like. So if someone rich is watching or reading this, fund an expedition to the Alcantara formation!
The burning of a museum of that size is just so unimaginably tragic for us nerds... we want answers damnit!
I wonder if 3d scanning and ct scanning to solid models of rare fossils should be mandatory to prevent the complete loss of precious specimens to history.
This right here
As a Brazilian,i can confirm the existence of these guys.
I've seen them mostly in small,deep rivers.
They get beautiful in the mating season.
They seem to be scared of fire, don't know why tho.
I'm more curious about the small deep river you mentioned..¿
was that before you tended to your extremely venomous snake collection?
Or maybe some of those magic plants potions and smokes ...
@@christines.5241 i don't know why You guys doubt my sanity.
Aside from my dementia,autism and schizophrenia i am perfectly healthy.
@@CeratsTheCrunchI am so sorry. People are too rude and judgemental nowadays.
I cried so hard of anger when the museum burned down. Unfortunately, Brazil and historical preservation and memory don't match well. Some improvements have been made, but very slowly
Spinosaur fossils trying to not get destroyed challange : impossible
Spinosaurids in my opinion were a mix between a crocodilian and a grizzly bear. Fisher or not, that's a terrifying combo!
Oxalaia and Sigilmassasaurus are very enigmatic dinosaurs, was it a new species, or just another Spinosaurus?
If the Jurassic franchise ever wanted to have a paleo-accurate spinosaurid they could introduce the oxalaia
How do they know Oxalaia was pretty much a Spinosaurus twin? The only fossils that have been found of Oxalaia are part of an upper jaw and some smaller parts of the snout.
Because its skeleton was almost the exact same. But I still don't understand why they thought it had a sail like Spino.
@@sitafuller497 Infered from the assumption of it being closely related to spinosaurus.
Thank you for mentioning this guy, I've seen it soo many times in paleo books but always wanted to see it in a documentary someday.
great stuff, love the art you showcased
What an odd coincidence that I’ve just published a stopmotion video on oxalaia today as well😅
Very good stop motion, I seen it!
@@sitafuller497 thx
SOMEONE HAS FINALLY GIVEN ME ATTENTION!!!!!!!
Ayyyy
Ooh boy, another Extinct Zoo banger.
Every Saturdays.
I very much enjoyed your video and I gave it a Thumbs Up
The first Spinosaurus fossils found: got blown up when a bomb fell on the museum during World War II
The first Oxalaia fossils found: got burn down when the museum caught fire
Random tip, the x is pronnounced as "sh" like, oshalaia! Great video mate!
I would have thought it would be an "h" sound like in Oaxaca or Mexico, but it makes sense that it's "sh" because Portuguese.
This was an amazing watch. Among all dinosaurs, the spinosaurids are my favorites (I can so very much relate to being the odd and ungainly one with different abilities than most, heh) and now Oxalaia is a star in that constellation for me. So thanks!
"Babe, wake up. Extinct Zoo just dropped another video, and this one's about Spinosaurids!"
_RUclipsr simulator bot_ comment
What's the punch line?
I am from Brazil and i love spinosaurs. My favorite spinosaur of my country is irritator.
3:17 all imma say is THAT angle from THAT pose git me feelin like imma do smthn to that spino
they probably moved along the bottom of a body of water similar to modern day hippos explaining its heavy bone structure
Fate has it out for Palaeontologists regarding Spinosaur fossils.
Everytime that this kind of fossils gets found, it will be destroyed
Man, i think that is a canon event & there's no way for us to change it
well,i am from brasil,more especifically from rio,where the museum caught fire in 2018,feeling represented
Great video sometimes I wonder if the same type of Dino’s were wondering around Brazil roughly 95mya meaning another spino, a similar carcharodontosaurus etc. Mike
i think Baryonix is my favorite dino in that family (pretty sure Barry is a spinosauridae) When I was little I had a toy for him and it's name is cool! He's missing his sail but the midweight version is certainly a terror in its own right
10:19 cursed but besides that I have always been curious about this spinosaurid thanks for making this
Another awesome video ! Please tell me where I can find the image in 2:19
Nice video
Oxalaia could be a subspecies of spinosaurus due to the small evolutionary differences like the sale and more tightly packed teeth and a straighter snout 3:51 my theory is that oxalaia and spinosaurus had a very close ancestor but split off very recently so one is more suited for a semi-aquatic/hippo life style and oxalaia is somewhat more of a land based spinosaurid with it’s more straightened snout or it hunted like spinosaurus and eating fish but that’s just my theory
Thank you, Extinct Zoo, for making sure we understood that the creature in the thumbnail did not represent an photograph of a living Spinosaurus ! That was close, man! Dude, I was so captivated, initially,by what I thought to be photographic evidence for the discovery of an extant example of that species, and just before the first tear of horrified wonder could drop from my astounded eyes, I saw the caption. Whheeeeewwww! Can you imagine my relief! There was absolutely zero sarcasm in the preceding remark👍
2:28 I would argue that Carcharodontosaurus would’ve been the apex predator of Northern Africa rather than Spinosaurus but that’s just my opinion. Being longer and possibly heavier does not necessarily mean it would be the apex predator of its environment. For example Allosaurus is pretty universally considered to be the apex predator of the Morrison Formation despite being smaller than Saurophaganax and Torvosaurus (though to be fair Allosaurus is far more common than them). Diet likely plays a role in food web hierarchy because a Spinosaurus is clearly evolved to take on aquatic prey but probably would not be above taking on smaller terrestrial animals but certainly nothing as large as itself. Carcharodontosaurus on the other hand being a large Allosauroid likely feeds on anything it can get like ornithopods, smaller theropods, young sauropods, and even large old or sick sauropods through mobbing/pack hunting behavior similar to what is theorized for Mapusaurus
you should consider doing a video looking at the dinos in the game Ark and seeing how close they are to realistic . i know everyone in our game's community would LOVE it :-)
I love that there's a dino called Irritator
Spinosaurids are so majestic
I'm sure a fish and small animals diet was probably one of the best food niches in this era. Full of energy and vitamins
I'm sure you're a fish as well xD
I think we should classify it as Spinosaurus quimbensis because it resembles Spinosaurus Aegypticus a lot even though they live in different continents but like Panthers and lions live in different places but are still considered to be in the genus panthera even though their mouths are different most species in the same genus of corse has different features
It reminds me a lot of modern crocodiles. Being opportunistic hunter and being primarily aquatic but also hunting on land
Fascinating!
Wish I could time travel to see this magnificent creatures 😍
Dang, I have never heard of this dinosaur until I watched this video!
One of the most iconic and as well as the most confusing dinosaur to science. 😂
James Gurney art is gold!
The simplest explanation is that the Spinosaurus parent species was present when South America and Africa split apart. It's recreation with a sail is a perhaps a stretch though as only 2 other species featured large ventral structures.
Irrigator by like Damm I thought it was gonna by me.
I thought this was about Sigilmassasaurus, Although yeah Oxalaia content is welcome too. explains why this guy wasn't anywhere to be seen when I was doing school projects, It was discovered in 2011... I graduated from School in 2013...
Spinosaurus: bombed
Oxalaia: burned
Irritator: stolen
I imagine that due to its general body shape and weight distribution plus the nose location, it spent a ton of the time in water and probably ate a lot of fish.
Due to the legs being awkwardly placed in relation to its body weight distribution, I can’t imagine it was doing a ton of land travel. That being said it could definitely get a decent speed if it needed to charge at something so I imagine it was like a much more adept alligator.
Imagine an alligator that could actually be extremely adept on land! Terrifying
The moral of this story is that if you're a museum and someone offers you a recently discovered Spinosaurid fossil, best just say "no."
nice!!
4:22 jeez, between this and the Spinosaurus skeleton being destroyed in WWII, history hates Spinosaurid fossils. And I had heard of Irritator before watching this video but not Oxalaia.
This channel so dope. Never knew about this dinosaur
that fire must've been devastating to so many, even if no living being was hurt. there weren't any casts sent to other museums?
Fortaleza mentioned!! 🇧🇷🫡
Extinct zoo will you ever do science videos of movie dinosaurs?
Movie dinosaurs aint real how can bro research them? The only thing he can research about them is their behavior shown on screen. So that video would be very useless.
Damn, I remember a time, way back when, when the no.2 was Allosaurus
I wish someone would do Sauroposeidon, its 2 little bros Brachiosaurus and Giraffititan get all the attention. 🦕
I swear the Spinosaurids all have just the WORST luck when it comes to fossil survivability
Oxalaia a Brazilian spino and An impressive Dinosaur
This is why research casts are important.
Hey extinctzoo just a question why are you starting to delete some of your older videos now?
Oxalia be a prehistoric spino crocodile 💀
Can we have a video on all the spinosurid family
Isn't it an irony that both large spinosaurus' fossils are lost.
I remember like yesterday when they found him. I quickly ran to the museum to see the bones, I was 12 and I lived in the capital of that state (São Luís), not very long they made a event with many things, and one of them was him in full size (bones only), but of course it was based on the old Spino body (the JP3 body type).
Now a sad fact: The museum where his bones were, was hardly a museum, the museum it's located in the "historical" part of the capital, and was pretty much a room with some fossils and some paintings (one of them was Oxalaia), I bet the living room of some of you is bigger than the museum.
A fun fact: His name comes from a Deity from Africa, and alot of the culture of Maranhão shares from Africa.
The skeletons of these relatives look so similar to my eyes. I wonder how distinct their colourations and fleshy bits would be.
Factor Trace made a video to explain about Spinosaurids and includes Oxalaia, 3 months ago. He says Oxalaia was the largest South American theropod known to science.
Was half expecting a spinofaarus video 🤦🏾🤦🏾
Short answer: it's oxalaia
Another use or benefit for the sail that I rarely see mentioned involves hunting fish. There are other ways to hunt fish then pursuit hunting and one such way is to use reach or bursts of speed to ambush prey and is used by both fish and crocodilians today. Reach can be accomplished by making a U-shape of the body towards one side. This will give a quick and long reach attack that can catch prey unawares of them being in danger. The sail would help with this tactic as it would act as a stop to prevent the center of the U to move in other direction too much.
The main thing is that I can't imagine an animal group this successful and spread out with this many aquatic adaptations not being able to hunt in the water.
In 2018? I MEAN what they were thinking that they would make raining? Unbelievable loss!
Damn every years when someone put a Spinosaurid skeletons in a museum its either got destroyed, got burned, got stolen or missing.
If i had a time machine there is one thing i want to do more then anything, and that is going back and getting a real look at what a spino acually looked like. So if a time traveler comes across this, help us out bud.
Extinct zoo, how many more things have we gotten wrong about the spinosaurus
So these were basically walking Alligators / Crocodiles but much scarier cant imagine coming up on these with stone spears 😱
To add: Many argue the strange spine of spinosaurus had the same function as similar spines on buffalo: Attachment points for enormous back muscles allowing them to easily drag, tackle, or even throw animals the size of rhinos.
Except that's literally not possible, there'd be signs of muscle attachments for such a thing.
And yet note the flimsy ass snout that is not made for grappling animals of the same size no matter what JP wants people to think.
There is a reason why the humpback sail idea didnt end up catching on in modern times.
@@ModernTyrannosaurusit just doesn’t make sense to me it goes right up with knuckle walking spino for me
where did you get all this info from lol
Haha, shows that you know! I already knew about Oxalia 😌🙂↕️
Sigilmisaurus be like
I think its interesting that the Spino found in South-America is named after an African deity, but not the Spino found in Africa. The Spino found in Brazil could have been named after Indigenous Americans of Brazil. Though I understand why, AfoBrazilians ARE Brazil's dominant culture. But its fine. With that said, Obatala is a sex/gender fluid Orisha, an Irunmole to be exact, a type of deity of the Yoruba people of west-Africa. Obatala along with Yemonja-a female Irunmole, are the duo that are responsible for creating the first human-bodies as commanded by the God of the Yoruba people Olodumare aka Olorun-who is sexless/genderless.
Science already has enough trouble with one Spinosaurus and now we have two? Goddamnit.
first thought he was crocodilian
So looking at that creature, how does it not fall flat on its face when walking in the manner depicted in the video? I mean its body seems to have the same thickness from hip to chest. Its forelimbs appear to be almost the same size as its hindlimbs in thickness and density. Its tail does not appear to quite have the counter mass to balance it on its hips. And that head is enormous and must have been quite the weight on its own. By comparison with Tyrannosaurs where the forelimbs are significantly smaller and the chest tapers in from the hips this creature seems to be defying gravity and a centre of balance to achieve the posture depicted.
Babe! New Dinosaur just dropped!
new dinosaurs before gta 6
BRASIL MENTIONED🗣️🇧🇷
Sigh, sails were not for heat regulation. Several studies have concluded that they can't have that function
Uk shite bout animal Biology
dimetrodon had a similar sail construction as Spinosaurus, and its sails are commonly thought to have been used for thermoregulation
@@rebelcat550 The aforementioned studies have examined Dimetrodon and conclude its sails were for ornamentation only
The Spinosaurus Rabbit hole deepens
I was asking the question why were dinosaurs so big? What if it evolved a larger body size to combat the lower oxygen levels. We see the same body plan phenomena in the fossil record in high elevations. And, might answer why the hobbit human was small because of the lack of food and a kinda elevation dwarfism.
7:19 that would make its bite force 10 tons
It's widely known here in Brazil not only they existed, but they never really went extinct. They evolved and adapted. Nowadays they are way smaller and are called "chupacabras", a common pet to us Brazilians.
Why is it its own genus and not a sister species to spinosaurus if they're so closely related/potentially synonymous?
thouse arms at 5:27 belong to Deinocheirus, ive seen that picture so many times
