Tyrannotitan: One Of The Largest Known Theropod Dinosaurs

Tyrannotitan was among the largest carnivorous dinosaurs and a candidate for the largest. Like the more famous mega-predators Giganotosaurus, Mapusaurus, and Carcharodontosaurus, Tyrannotitan was a member of Carcharodontosauridae, especially the small subgroup Giganotosaurini along with Giganotosaurus and Mapusaurus. Tyrannotitan was the oldest giganotosaurine, living in Argentina during the Albian stage of the Early Cretaceous period between 113.0-100.5 million years ago.

I think it's interesting that the Carcharodontosauridae group produced so many giant predators. T-Rex and Spinosaurus might be the superstars of the Theropods, but the Carcharodontosaurids like Carcharodontosaurus, Giganotosaurus, Mapusaurus, and Tyrannotitan (which has one of the coolest names for a predatory Dinosaur btw) deserve their fair share of the spotlight too.

The titanosaur/carcharodontosaur rivalry has to be the most underrated feud in paleontology. Not only is it between both the biggest herbivores and the biggest carnivores, it's also multi-generational, with different genera from different time periods duking it out. You mentioned Patagotitan & Titanotitan and Argentinosaurus & Mapusaurus, but there was also Andesaurus & Giganotosaurus in between them. The only other time I've seen this kind of generational rivalry was with the tyrannosaurs & ceratopsians (which frankly do it to a way bigger extent and will probably never be topped as _the_ prehistoric rivalry). It's all really cool stuff, and something that needs to be represented in more paleomedia. So far the most well-known portrayal of it was in Planet Dinosaur, but that's about it.

the whole concept of flesh grazing is terrifying. thank you for making these videos!

[@Macrochenia]

If Tyrannotitan practiced flesh grazing, the open wounds left on its prey could have served to attract other Tyrannotitans in the area, similar to the way Komodo dragons congregate on a water buffalo after it's been bitten by one. In that event, it wouldn't really need to form packs to hunt, per say, because the instinctive mobbing behavior would serve much the same effect as individuals dove in to take opportunistic bites as the unlucky sauropod continued to weaken from blood loss and further injury.

I find it really interesting that 3 of the 5 biggest carnivorous dinos were all apart of this family. The only two outliers being the Trex and Spino. I wonder why this family of dinosaurs had to be so much bigger than the others in the rex and spino families. Assuming it's due to the prey they mostly hunted based on the info provided in the vid.

[@horvathbenedek3596]

Two reasons, I think. 1. Because of their prey's size. 2. Because tyrannosaurids didn't have enough time to become truly large. The reason tyrannosaurids even developed was mainly due to the ecological niche of large bodies predators disappearing in the form of allosaurids. Now, allosaurus was a medium sized carnivore that evolved 155 M years ago, while Charcharodontosaurids died out around 95M years ago. That's 60M years. Tyrannosaurids evolves from 80 M years ago, starting with Lythronax, an animal roughly the size of an Allosaurus. The fact that tyrannosaurids managed to fill the same niche under 14 million years as allosaurids did under 60 is impressive alone, and a testament to their superior body plan, but even then, that's 44 million years worth of advantage.

[@NickSibz]

[@rileyernst9086]

I support the idea it usually hunted alone and hunted in groups during times of oppotunity or harshness when prey might be at its scarcest(the second half of the dry season). Even intensly social animals like wolves, do not hunt in packs all year round. They will hunt small prey most the year but in winter or when the oppotunity arrises the pack is summoned. I think therapods could have been quite social at times and reject the seemingly mammalian biased idea that they were incapable of forming lasting social bonds because they were stem birds and had different brains. I think communication was vital to therapod reproduction and thus evolution and this very well might have translated to social behaiours.

[@chimerasuchus]

I agree. To add to it, something that is often overlooked in the discussion of theropod pack hunting is that Cuban crocodilians (who spend more time on land than most other crocodilians) have been observed engaging in what appears to be true pack hunting. If they can do it, so could the carcharodontosaurid could have as well.

[@KFrost-fx7dt]

I just don't see dinosaurs being intelligent enough to hunt in organized packs. There are no living birds that do it, and their brains are much larger (compared to body size) and have more complex behaviors. There is evidence of theropods feeding together though.

[@chimerasuchus]

@@KFrost-fx7dt Harris's hawk does sometimes hunt in packs. Perhaps more importantly, Cuban crocodiles have also been seen engaging in cooperative hunting while on land. While pack hunting in the expectation rather than the norm in modern archosaurs, their modern representatives do show it was also possible in dinosaurs.

[@rileyernst9086]

@@KFrost-fx7dt firstly it depends if you belive that social behaviour evolves because of intelligence or nessecity, i believe nessecity because thats how evolution tends to work, the enviroment and factors force the animal to adapt its behaviour, it depends on what you mean by coordinated pack hunting. Lions do not coordinate. They charge in like 6yr olds at a soccer ball. They are as individuals capable of bringing their prey down by grappling. Wild dogs and wolves which hunt the same prey (in africa(wild dogs) and india(wolves)) are much less capable of bringing down large prey as individuals are extremely coordinated. Therapods are lions not wolves. A key factor that actually defines packing behaviour is if they live and hunt in social groups. King's skink of Western Australia is a large viviparous skink, it lives in family groups, and lives on windswept areas where burrows are of large demand. The family, complete with grown children will pattol and defend the area around their burrow. And that is a skink with a tiny skink brain, which is tiny in comparison to its body size. Its prey generally consists of smaller animals so sadly we will probably not see them hunting as a family unit. But if those circumstamces arose, yeah i think they would. And bam pack hunting King's skinks. Adult Specticled caimans in the Orinoco wetland look after large mixed creches of hatchlings. Because half the year most the pools dry up and the young would perish otherwise. Black vultures are extremely social and extremely territorial and rival groups will often clash. Whilst its not hunting, they are a very social modern therapod that gets into some vicous gang fights( including literally biting and tearing chunks of skin off rivals and eating it). (This is a freat counterpoint to the argument that is often put forwards: 'that we have evidence of cannibalism and interspecies violence in dinosaurian therapods so they can't have been social') Crocs also have been observed corraling fish, in orcas, dolphins, pinnapeds and whales this is packing behaviour. Animals adopt sucsessful behaviours. Smarter animals like us can adopt them on the fly, without the need for biological hard-wiring. This includes making friends. Therapods had to be able to communicate to avoid conflict and especially when breeding(-insert joke about wife biting your head off-). It makes sense for breeding therapods to have a deep bond of trust, simpily because the danger posed by the other party, also based on gestation times and metabolism it is highly likely both parents cared for the eggs(or else they would have been extremely vulnerable( with the current thinking that like crocs and turtles comparatively few dinosaurs made it to breeding age, those that did breed sucessfully would have to have to maximised sucsess(large therapods also seemed to have layed comparatively few eggs when compared to herbivores) . It is entirely likely that some species would pair for life. So what i am saying is we have a bonding mechanic and communication. Oppotunistic group hunting, as seen with nile crocs etc is entirely possible, actual pack hunting, ie where the group that is hunting is socially bonded is no as unlikely as might be thought. Its less likely than amoung viviparous critters (like marine reptiles who like King's skink were in a pretty rough enviromemt). Did tyrannotitan hunt in packs? Unlikely, but really could have happened. It most certainly formed groups to hunt because literally everything does if the opportunity is good enough(and an old or sick 30 ton sauropod IS a good enough opportunity.) Did some species of plesiosaurs, icthyosaus mosasaurs or pliosaurs hunt in packs? Yeah probably. Do they have big ole mammal brains? Nope.

[@horvathbenedek3596]

@@KFrost-fx7dt "there are no birds that do it" Because there are no carnivorous apex predator birds, because mammals arer vastly more successful for the most part. If you want evidence of birds being able to cooperate as a social group... Corvids literally have a family and community structure that is on par with primates. Also, corvids are one of few animals capable of comprehending their own existence, as evidenced by the mirrot self-recognition test. They are more intelligent than dogs, cats, or pigs, ranking just below apes.

[@DreadEnder]

So underrated and it’s freaking massive! I saw a skull in person and it’s way bigger than me.

[@rileyernst9086]

Maybe tyrannotitan was more of an ambush predator than the later giganotosaurids, i am not sure about the trends in climate during the Cretaceous, but if south America became more arid and less forested it is the trend I'd expect to see in the family's evolution. That is a hypothesis to explain its less pnematisied bones, more powerful arms(which would have been much more useful as a juvenile or sub adult) and more straighter and less specialisdd teeth. Could just be it was more basal. It should also be pointed out that therapods with similar teeth are responsible for some frickin deep gouges into considerable sized bones. Trex gets a lot of credit for crushing and chomping bone but the record for bone filled corprolites belongs to an allosaurus from Utah the (brushy basin member of the morrison if i recal correctly) the corprolite was like 1.52m long + dribble and featured big chuncks of bone abd lots of ground up slivers. Like what you'd expect to see if it was essentially sawing bones appart(like how they leave the gouges in the big bones) and ingesting them. Predation on large sauropods to me is an odd subject. Sauropods are easily the most dangerous animals to have walked the earth. I think if i were a carcharodontosaurid hunting a sauropod the first thing i would want to do is get it alone at night, in a wooded area so it can't manouver easily then cut those rear legs up to imobilise it and get it bleeding(like wolves hamstringing a musk ox or bison). Then just sit back and wait. Its still extremely dangerous and can crush you like a bug and there is nothing to be gained by pushing the attack till it weakens. And that is even just a sick or old individual.

I had a dream years ago when I was a teen, about a hot humid place, with strange palm tree looking plants, with a reddish almost violet colored sun. A large brontosaur looking dinosaur(much larger than a bronrosaur or even a brachiosaur)! came running out of the trees, terrified running for its life. A pack of huge tyrannosaurus looking things came running after it. (Much larger than a T-rex) They were leaping onto it and clawing and biting it. I was shocked they could jump so high, from the ground straight up to its literal back and spine. I mean this four legged long necked thing was GARGANTUAN Even though these two legged predators were huge themselves, it dwarfed them. Yet it was clearly terrified of this group of them. Yet just one of them was able to rip wounds big enough to pour blood out like a stream!! That's what I remember the most, the blood. So much blood. Blood everywhere. That's how they killed it. Bleeding it to death. I was horrified. Guess that's what I get for asking God desperately to see earth when the dinosaurs were alive. It was not a nice place. So Hot, so humid, couldn't breathe. Everywhere was death, and death was everywhere. I wanted to see, but I wasn't prepared for how hellish the whole place was. Temperature: Horrid. Appearance: Horrid. Inhabitants Worse. Overall ambiance: Alien Hellscape. Where humans could never flourish. Only subsist in constant terror and squalor. I also saw a T-rex. It was worse. Much more muscular. It's eyes faced forward in a horrible way. Such huge eyes, so malevolent....You knew it was looking at you. It could see you well before you saw it. It would actually fuck with things. Pretending it was accidentally approaching you making you think it wasn't seeing you. It's bite was worse. It didn't bleed anything. It crunched it up one bite was death. Oh God the oceans...No. P.S..the larger 2 legged predators that bled out the sauropod were yellowish in color.

[@chimerasuchus]

It isn't certain. The larger weight of Tyrannosaurs is from comparing the largest known individuals to each other. Tyrannosaurus is known from a lot more specimens than either Giganotosaurus or Tyrannotitan. The estimated weight of the two known Tyrannotitan skeletons is within the average weight of Tyrannosaurus, though that is with a small sample size and incomplete specimens. Without a better sample size and more complete specimens of the large carcharodontosaurids, it is hard to say for sure if Tyrannosaurs was larger, though it does seem more likely.

[@fatih9016]

​@@chimerasuchus I agree , there can allways be a specimen we donn't know about thats much larger than any Tyrannosaurus. Tho for now I think it's safe to say the Tyrannosaurus Rex is the largest known theropod since pretty much all of them are a bulkier overall. They also have larger legs and their feet design are quite different than other massive theropods like the middle bone of the foot that connects to the middle toe is like it's crushed between the other two at the top , that reduces the movement of the bones and makes them more stable when the animal walks. This way the foot can carry more weight.

Tyrannotitan is 13 meters long and 7-8 tonnes giant monster 👹

Must be 10 tonnes monster bro

[@highfive7689]

These Giganotosaurini therapods actually look like runners with longer legs so they could move over terrain quickly. Unlike the T Rex "Sue", which does not look like a capable effective hunter - more like a duck. Thank you for presenting this episode!

Wasn't there a size amp for all dinosaurs half a year ago? According to it scotty wouldve have about 10 tons.

[@jefflehoux9619]

I’ve often wondered if any of these “flesh grazing” theropods may have had septic bites, and hunted in a manner not unlike the Komodo dragon lizard. Unfortunately I guess we will never know.

Man just imagine living with these beast, Iike a massive fast alligator, what a terrifying time it must of been.

T-Rex is though to weight up to 9 tons which to technically make it the largest Theropod, because Spinosaurus could weight up to about 6-7 tons

Yes, it was a also a carcharodontosaurid, though it wasn't as large.

Tyrannotitan was smaller than T-Rex, and even Giganotosaurus was bigger. T-Rex grew 12 meters or more, whilst Tyrannotitan only grew up to 11 metres.

SSSSSPECIFICALLY. until you were talking ocean side, but it didnt sound like that. lots of info pack into 8 minutes tho =) learning happened

[@jon368100]

I don’t think Tyrannotitan is the direct ancestor of Gig or Map. When you look at the differences, it just doesn’t make sense. It has smaller arms, a more robust skull with straighter teeth, and a back/tail with more robust bones and muscles. Gig and Map are way too similar to Carcharodontosaurus especially when you compare to Tyrannotitan. My guess is that Tyrannotitan evolved for the needs of the time, and then more sophisticated Mega predators more closely related to Carcharodontosaurus moved in later.

[@mhdfrb9971]

I mean their close ancestor, Veterupristisaurus are doing well in late Jurassic Africa

[@calonyoutuber1399]

Still no predator has more robust skull as the trexses as big as they may be

[@orionparish9858]

Tyrannotitan definitely wins an award for having an awesome name 😄. Who cares if it wasn't related to T-rex?

[@justhereforkicks8208]

I find it weird that we keep finding bigger and bigger dinosaurs. It’s crazy to think monsters like these were once living, breathing animals.

[@georget4141]

honestly, the question of whether one dinosaur is bigger than t. rex is pretty meaningless and doesn’t really add anything to this video. really great before that point tho!

[@theadmiral4157]

Argentina became a home for very large dinos (argentinosaur, giga and tyranotitan is an example). I wonder why

[@the1sonder884]

One thing I’ve been seeing a lot is people saying, “You can’t use Sue or Scotty to compare T. Rex to the other giant theropods because they are exceptional.” and I’ve got to say that reasoning is flawed. For all we know, the remains we have for the giant carcharadontosaurids could either come in on the lower end of the size estimates, making Rex bigger, or they could be exceptional for their respective species as well.

[@creativescreenname2750]

Trex is also still considered to be bulkier, we always hear "bigger" but that's subjective and typically just means longer. Even Spino had its weight estimate drastically reduced last year

[@aryatejc8067]

0:58 Yeah i know that... i used to think it was related to t rex but oh boy was i wrong back then...

[@peterlewerin4213]

"The new hypothesis, that the two Tyrannotitan specimens found so far were significantly smaller than the average member of their species, is based on further analysis of the site and the circumstances of the find. Apparently, the two Tyrannotitans had been shoved into a locker, presumably by bullies."

[@sylviebleicher4903]

Avec 13 mètres de long et 7 tonnes ce superpredateur rivalisait véritablement en taille avec le T-Rex mais aussi son cousin le mapusaurus ( le plus grand était giganotosaurus ,13 a 14 mètres 8 a 9 tonnes ! ) d'ailleurs on entend tyran dans son nom même ce n'était pas un tyrannosaure mais un allosauroide carcharodontosauride.
