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.
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?
@@ArielMurrayDrakonslayer777 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. 😁
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!
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 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.
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
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.
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.
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!
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
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.
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 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
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👍
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 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
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
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.
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.
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.
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.
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.
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
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...
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 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 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
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.
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.
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 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.
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.
Oxalaia means chief in Africa and Oxalaia is the sixth largest carnivore with an adult weight of 7,826 kg making it the largest carnivore in Brazil. 2:14
@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
4:24 I have always had this two-faced relationship with modern science and museums. I love the knowledge gained and the scientific method. But i hate how we are destroying everything in the process. Fossils that survived anywhere from tens of millions to over half a billion years are safe to assume that could have survived another hundred million years. But we collect them and collections get destroyed left and right due to wars, terrorism, stealing, natural and technological disasters. Not to mention the long East Asian tradition where ancient fossils are ground and consumed for superstition. Knowledge and seeking of knowledge is super great. But our accumulated knowledge is so vulnerable. Including all data storage methods. On the long run, better people may come along who could solve these problems. They can be our descendants or a really intelligent and wise species in our planets deeper future. But they will have much less to work with. 😞
Man spinosaur fossils have bad luck not being destroyed in museums

I have always had this two-faced relationship with modern science and museums. I love the knowledge gained and the scientific method.
But i hate how we are destroying everything in the process. Fossils that survived anywhere from tens of millions to over half a billion years are safe to assume that could have survived another hundred million years.
But we collect them and collections get destroyed left and right due to wars, terrorism, stealing, natural and technological disasters. Not to mention the long East Asian tradition where ancient fossils are ground and consumed for superstition.
Knowledge and seeking of knowledge is super great. But our accumulated knowledge is so vulnerable. Including all data storage methods.
On the long run, better people may come along who could solve these problems. They can be our descendants or a really intelligent and wise species in our planets deeper future.
But they will have much less to work with. 😞
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
