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.
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.
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? Fake Edit: I thumbed it down to help even things out. :)
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!
All the museums in the world should be protected from any type of danger at all costs. We CAN NEVER afford to lose such precious items millions of years old.
@@Rhythm412 it already is against the "rules of war" but mistakes happen and nobody can or wants to realistically enforce those. Like what is america just supposed to join germany in WWII because a museum blew up? Russia might have burned it own "amber room" by mistake in WWII whos getting punished for that. They claim its lost does someone get punished for lossing artifacts? Its a whole can of worms
Bro, every time we find a new Spinosaurid, we should make one-to-one copies of the fossils so no matter what happens to the original ones, scientists will know what it looks like.
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.
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...
I love how much meme potential the spino has been bringing in the last few years, from perma changing in fossils and estimated environments to live in, to now having 2 fossils getting destroyed.
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
Might have something to do with the means of death millions of years ago. Either way spino bones should be stored in a fireproof bomb proof bunker just in case. Just to be on the safe side.
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.
Oxalaia is literally the spinosaurus's own equivalent of the tarbosaurus, cause they both look very similar (besides some differences), Spinosaurus is larger than Oxalaia, they both live in different continents that used to make Gondwana (Like NA and Asia (exluding indian subcontinent) that used to make Laurasia), Oxalaia was considered a synonym of spinosaurus (like Tarbosaurus was just another species of the genus tyrannosaurus) and occupied the same niche.

Man that's crazy we thought trex was heavy now this coz the Rex seems a little more bulky than a sino but maby that spine and tadpole tail gave it a weight buff
@@DavidArmanAlonzo Spinosaurus is heavy due to its impressive body dimensions of length, height and width, and then a very high bone density of 40% to 80% more than Tyrannosaur. The more dense a material is, the more its mass increases. In addition to the largest sail in history and an enlarged tail, as you said, and do not forget the huge arms that have proven to exceed the proportion of the arms of members of its family. Indeed, Spinosaurus deserves to hold the world record for the bulkiest known land carnivore ever for more than 100 years since its discovery.
My thoughts are that spinosaurus used the fact that it was semi-aquatic and very large to scare off anything that it didn't want to fight, while scrounging for fish and smaller terrestrial creatures. Basically, it bullies everything into leaving it alone and hunts peacefully against things that are defenseless to it. The giant sail would scare the hell out of anything big, and the size alone would scare the hell out of anything near the water (you see a giant displaced creature coming towards you under the water, even something as strong or large as a rex would probably flee. I don't think that the spinosaurus could actually fight off any large terrestrial predators, but like I said I don't think it would ever need to.
Possibly, I mean it likely could just p**s off into the water if anything did try to fight it. Likely whilst laughing and taunting whatever wanted to fight it. We will know if this is true if we ever discover it had an elongated middle finger with good flexibility for flipping off rivals.
I love how you list off many of the animals that your focus species co-existed with. Really helps to paint a picture of the environment that the focus of the videos existed in!
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.
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.
@@mikekoblosh8412That's only the case if you find very few remains. We've got a really, really large amount of fossils which roughly tell us the evolutionary history of most vertebrate animals. Fossils aren't the only evidence for evolution. Think of the case of the different finches on the Galapagos islands. Even more recently scientists have tested the mechanics of evolution on basteria during 10 year long expirements. Evolution being an incredibly slow process makes it difficult for us humans to understand and believe, but being ignorant of the facts doesn't make one an expert on the topic either.
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
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
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
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 Edit: I kinda forgot that an apex predator is defined as a predator that has no natural predators of its own in its respective ecosystem, so most of my reasoning is basically wrong
@@King_Shadow_Reaper Looking back on my comment you are definitely partially correct, but they would not both be apex predators because of them occupying different niches. They both would’ve been apex predators simply because neither of them would have natural predators as adults (which is what defines something as an apex predator).
@frankiek_1 although, these megatheropods would surely clash during territorial disputes, times of scarce resources, etc. You are never entirely safe in the mesozoic.
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.
I don’t remember if he said it in the video but one thing that is pretty solid proof that they are different genuses is that they probably lived a few million years apart. Also since they lived on a different continent that’s also some pretty good proof.
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👍
I believe they could swim but not dive. I think it would stand in shallow rivers and banks. Rear back on its hind legs a little and arch is neck over pointing the tip of the snout in the water and as something came by it would lunge and grab said prey. Its thick and long tail would be used to counterbalance its momentum when striking. Also using it as propulsion to cross deeper bodies of water. The snout probably had specialised skin that helped detect movement. I also think its claws could used to dig into river beds to hook or displace fish burrowed in. Though they'd also be a nice weapon.
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!
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...
I knew it was Oxalaia before the video even started because I remember seeing it in animated dinosaur battle videos before searching about this dino when I was younger, I'm so proud of myself
I feel that if we ever did get to find a complete Spinosaurid skull it would have a smug smirk knowing how many paleontologists it's driven mad looking for it.
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
8:34 makes me think of that monster from Monster Hunter, Jyuradotus. It’s like a mudskipper, it can only live in wet muck and swims through the surface of it like water.
I like to imagine they ambushed like modern day crocodiles. Just the eyes and nose sticking out of murky water. Completely stealthy. Except they forget they have the sail on their back so they stick out like a sore thumb.
Considering the sheer size of fossilized fish found in the same period, in areas where shallow seas existed, it's really no surprise that there were a number of large Spinosaurids. If 4' - 8' fish were somewhat commonplace, a Spino could wade in shallow water all day (much like a modern Gharial crocodile), and snatch fish.
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.
I just realised, the Spinal could have been the Hippo of its time with HEAVILY developed muscles and next to no fat, allowing it to just run under water
@Extinctzoo I have a question if you would answer. It is possible that the two spinos came from one species or a middle origin which evolved differently at the same time because of difference in ecosystem?
That's always possible, could even be as simple as one species was in a area with less large competition so it didn't get as bulky while the other did live in a area with large competition so being bulkier helped then survive
Ambushing like a croc seems doubtful considering the large fin on it's back. Not like it could sneak up on an animal at the shoreline drinking, while having this massive sail telling the prey "Hey I'm right here"
2:28 except the fact that while smaller, charcarodontasaurus lived in the same place and would have destroyed spino in a fight because spinosaurs just aren’t built to fight.
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.
The Crocodillian skull shape is a proven form that has evolved independently in many different species of reptile, dinosaur, and even fish (alligator gar). The croc skull is a prime example of "if it ain't broke, don't fix it."
I cant wait for a million years down the road, for some new species to find my bones and be like: Its got a bigger nose, his feet point in different directions, and an enlarged middle finger on his right hand... Must be a new species of Human!
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.
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.
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.
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

They both would’ve been apex predators simply because neither of them would have natural predators as adults (which is what defines something as an apex predator).
@frankiek_1 although, these megatheropods would surely clash during territorial disputes, times of scarce resources, etc. You are never entirely safe in the mesozoic.
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.
Fate has it out for Palaeontologists regarding Spinosaur fossils.
well,i am from brasil,more especifically from rio,where the museum caught fire in 2018,feeling represented
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.
James Gurney art is gold!
This channel so dope. Never knew about this dinosaur
I'm starting to think spinosaurs are just a conspiracy at this point with them getting constantly destroyed in museums lol
SOMEONE HAS FINALLY GIVEN ME ATTENTION!!!!!!!
Ayyyy
10:19 cursed but besides that I have always been curious about this spinosaurid thanks for making this
I don’t remember if he said it in the video but one thing that is pretty solid proof that they are different genuses is that they probably lived a few million years apart. Also since they lived on a different continent that’s also some pretty good proof.
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👍
I very much enjoyed your video and I gave it a Thumbs Up
One of the most iconic and as well as the most confusing dinosaur to science. 😂
I believe they could swim but not dive. I think it would stand in shallow rivers and banks. Rear back on its hind legs a little and arch is neck over pointing the tip of the snout in the water and as something came by it would lunge and grab said prey. Its thick and long tail would be used to counterbalance its momentum when striking. Also using it as propulsion to cross deeper bodies of water.
The snout probably had specialised skin that helped detect movement. I also think its claws could used to dig into river beds to hook or displace fish burrowed in. Though they'd also be a nice weapon.
Another awesome video ! Please tell me where I can find the image in 2:19
My bro I love dinausors but never knew this and other things in ur channel so u deserve a sub my dude
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!
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...
I knew it was Oxalaia before the video even started because I remember seeing it in animated dinosaur battle videos before searching about this dino when I was younger, I'm so proud of myself
I feel that if we ever did get to find a complete Spinosaurid skull it would have a smug smirk knowing how many paleontologists it's driven mad looking for it.
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
the velociraptor is only popular thanks to jurasic world becausse in reality it was more of an chicken like trodon
8:34 makes me think of that monster from Monster Hunter, Jyuradotus. It’s like a mudskipper, it can only live in wet muck and swims through the surface of it like water.
I like to imagine they ambushed like modern day crocodiles. Just the eyes and nose sticking out of murky water. Completely stealthy. Except they forget they have the sail on their back so they stick out like a sore thumb.
Considering the sheer size of fossilized fish found in the same period, in areas where shallow seas existed, it's really no surprise that there were a number of large Spinosaurids. If 4' - 8' fish were somewhat commonplace, a Spino could wade in shallow water all day (much like a modern Gharial crocodile), and snatch fish.
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.
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?
You actually spoiled it at the start lol 0:49
I just realised, the Spinal could have been the Hippo of its time with HEAVILY developed muscles and next to no fat, allowing it to just run under water
@Extinctzoo I have a question if you would answer. It is possible that the two spinos came from one species or a middle origin which evolved differently at the same time because of difference in ecosystem?
That's always possible, could even be as simple as one species was in a area with less large competition so it didn't get as bulky while the other did live in a area with large competition so being bulkier helped then survive
Ambushing like a croc seems doubtful considering the large fin on it's back.
Not like it could sneak up on an animal at the shoreline drinking, while having this massive sail telling the prey "Hey I'm right here"
10:19 the sigilmassasaurus really fits its own name 💀
when im in a "being updated competition" but my opponent is the spinosaurus
2:28 except the fact that while smaller, charcarodontasaurus lived in the same place and would have destroyed spino in a fight because spinosaurs just aren’t built to fight.
Brontosaurus, T-Rex, Triceratops, Stegosaurus are the most popular from way back. Raptors only became popular after Jurassic Park.
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.
for some reason i thought this video would be some obscure jurassic park lore
ExtinctZoo Where do you get your information?
The Crocodillian skull shape is a proven form that has evolved independently in many different species of reptile, dinosaur, and even fish (alligator gar). The croc skull is a prime example of "if it ain't broke, don't fix it."
Imagine you dive into the twilight zone of the ocean and a freaking spinosaurus charges at you from the dark below
"Spinosaurus fossils seem to have the worst luck, either lost or destroyed before they can tell their full story!"
It reminds me a lot of modern crocodiles. Being opportunistic hunter and being primarily aquatic but also hunting on land
it had a wider jaw with shorter teeth, maybe it had a different diet and feeding strategy from its relatives 🤔
I cant wait for a million years down the road, for some new species to find my bones and be like: Its got a bigger nose, his feet point in different directions, and an enlarged middle finger on his right hand... Must be a new species of Human!
spinosaur will forever be my favourite prehistoric beast 😄
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
It's like the universe doesn't want us to know too much about these kind of dinosaurs.
Lol seeing the colour on the mock up sketches just screams
CRYSTAL PALACE mk2 😂 😂
I really wouldn't be surprised if Oxalaia is discovered to be larger than Spinosaurus itself considering South America's history with large dinosaurs.
Spinosaurus is the embodiment of “its just a phase!”
man imagine how many dinosaurs existed that we will never know about at all
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.
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
