T. rex hunting sauropods is not something you see everyday.

I feel like a lot of people forget that dinosaurs, specifically the T. rex, we’re just regular animals like the ones we have today. They weren’t monsters that killed things for the fun of it. A r Rex hunting a large sauropod would be like a lion hunting a large elephant or hippo. Maybe baby ones, but the larger ones they’d leave alone unless they were extremely desperate. Why would they want to fight something that could cause a serious injury to them when they could easily hunt prey that wouldn’t been alot easier. They were just regular animals. Large, dangerous animals, yes. But they weren’t these evil monsters that tried to kill everything in sight.

I honestly think they could do it. But it’s like lions going after giraffes or elephants. Definitely couldn’t be done solo

During the Late-Cretaceous period in North America, 99% of plant-eater dinosaurs were ceratopsians or hadrosaurs, so the t.rex was more specialized in hunting ceratopsians and hadrosaurs, rather than hunting giant sauropods. In contrast to mapusaurus or giganotosaurus, which directly specialized in hunting large sauropod (in group of course), because sauropods were much more common in South America..

To this conclusion, I add the case of Tarbosaurus which has a slimmer jaw than Tyrannosaurus. In Asia, sauropods had stayed common throughout the cretaceous.

I personally don't think a single rex would waste its precious energy trying to take something that large down. They're simply to much for a rex

A giganotosaurus could bite a sauropod, and then after release its bite, then bit again. A T.rex need to fixe its bite in order to crush the bones. But for doing that, it lost its mobility, thus it had a disadvantage compared with the giganatosaurus....

Juvenile sauropods would be easy prey for Tyrannosaurus. One bite to the neck would decapitate.

A lot of people here really tought giga went for full grown sauropods.

Agreed: you don't bring a can opener to a sushi contest expecting it to perform well. On the other side, if you need to open that can, you have the perfect tool for the task.

I remember it was once believed that the T.Rex fighting a sauropod would be too good to be true and that Giga vs Argentinosaurus would be the next best thing. Ironic now that we know Giga and Mapusaurus are separate species now but I'm distracted. The fact that a T.Rex fighting a Sauropod is now seen as possible to me shows just how quickly things change.

Maybe young sauropods but adult sauropods I doubt. They're just way way too large. Maybe they could take chunks and eat them alive but actually taking one down is a whole different story

Tyrannosaurus Rex - You underestimate My Power! Alamosaurus - Don't try it

T-Rex: *nips at Alamosaurus' legs* Alamosaurus: I'm about to show you that weight classes exist for a reason

Tyrannosaurus probably actively hunted young growing alamosaurus. Mainly sauropods at the mass of edmontosaurus and smaller, as they were probably easier than armed combatant triceratops. Also alamosaurus young were likely numerous, as sauropods laid eggs more like sea turtles (large amount of eggs to increase the chance of at least one growing into adulthood).

T-Rex was specialized in smaller but more armored preys, like ceratopsians or ankylosaurids, or preys like hadrosaurs, meanwhile other big terópodos like Giganotosaurus, Mapusaurus, Carcharodontosaurus or Acrocanthosaurus are more built for take down large preys like the sauropods. T-Rex bite was designed to crush bones, meanwhile the others have a better bite to inflict injuries and bleed

every time I think of Alamosaurus I think of that video by The Doodling Dino where he redesigns Arlo from The Good Dinosaur as one since Apatosaurus was not around during the end of the Cretaceous.

The "Nah, I'd win" meme is everywhere ever since Gojo died, JJK has truly changed because of Gojo.

Wait a minute... Does this mean Sharptooth couldn't have killed Littlefoot's mom? Was that movie inaccurate or something!!!?? Have we been lied to!!??

Could we maybe see a video on Australovenator(or just megaraptorans in general)? They are my fav cretaceous theropods along with spinosaurids and i think they are heavily underrated

The T. rex and Alamosaurus also coexisted both in the North Horn formation.

your videos are great, you will definitely grow much larger over time and as you master creating these videos

A lot of good points, however I will say the most likely reason T.rex didn’t prey on Alamosaurus is that they probably didn’t coexist at all lol. Despite popular belief, there isn’t any material (at least that I’m aware of) that can DEFINITIVELY be assigned to Tyrannosaurus rex from the Ojo Alamo formation where Alamosaurus is known from. I wouldn’t be surprised if most people reading this are scratching their head at the moment, so before I get the flow of angry comments correcting me just hear me out. 1.) the Ojo Alamo formation and the Hell creek formation both represent paleo environments from the same continent and roughly the same time, but this does not mean they were completely identical environments. The presence of Alamosaurus in the Ojo Alamo & the lack of the genus in hell creek is enough to confirm that alone, however there’s a lot more evidence which confirms this (I won’t go into detail so I can make this as short as I can, so lss: the environments were similar but Ojo Alamo was more on the arid side and the geography of the area was fairly different). 2.) Ojo Alamo and Hell creek do not share any other fauna (definitively at least). This is of course a generalization, I’m sure there was some overlap, but the regular fauna of each respective region were entirely different (though closely related to each other). Now I know what you might be thinking: “what about Torosaurus? Or Quetzalcoatlus? Triceratops ?! T.rex?!!!!! Yes, it is true that the genus Torosaurus was present in both ecosystems, however the Torosaurus remains from Ojo Alamo are assigned to a different species from the famous Torosaurus of hell creek and there is no known evidence of overlap. This is also the case for Quetzalcoatlus, the Hell Creek species was notably smaller and likely held a completely different niche than the famous Titan from the Ojo Alamo formation. As far as Triceratops goes, that one is a lot messier. The “triceratops” remains from Ojo Alamo are fragmentary and messy, and half the time paleontologists say they actually represent the genus Eotriceratops (which is honestly more problematic than just calling it triceratops due to the Ojo Alamo remains being far younger than Eotriceratops and are on the complete other side of the continent but whatever lol). Basically, it’s possible the genus Triceratops was present, but if it was it was likely a different species from the 2 known from the Hell Creek region. The little material known already shows some differences to the two species from Hell creek. It is also possible that triceratops wasn’t present at all but instead a very closely related genus was. And tyrannosaurus? Very similar story to Ojo Alamo’s “Triceratops”. All the “tyrannosaurus” remains from the this region are fragmentary and cannot be definitively assigned to Tyrannosaurus rex. Even in some of the oldest papers referring to this material call it “cf. tyrannosaurus” or just “tyrannosaurus?” and they intentionally do not call it Tyrannosaurus rex. It’s fairly likely the genus Tyrannosaurus was present, however it’d actually be pretty surprising if it came out that it was indeed Tyrannosaurus rex and not a second species of Tyrannosaurus (for realizes this time, not that stupid T. Imperator gobbledegook). It is also just as likely that the genus Tyrannosaurus wasn’t present at all, but in its place a second giant North American Tyrannosaurid was (Alamotyrannus stans rise😤). Also, I’ve heard some talk of there being evidence of there actually being at least 2 separate tyrannosaurids from Ojo Alamo though this is just heresay for now so take that as you will. (it should be noted that there are no papers going to explicit detail on this I don’t believe, as there isn’t enough material to have a conclusive answer that would warrant a paper being published, though from what I’ve heard there are paleontologists currently working on trying to clean up Ojo Alamo’s messy classifications but they are waiting for more material from the region). To sum it up, I really doubt that Tyrannosaurus rex ever actually frequented the Ojo Alamo or encountered Alamosaurus often at all, and find it much more likely that the Ojo Alamo tyrannosaur was either a second species of Tyrannosaurus or a new genus that was very closely related due to the fact that this has proven to be the case for most (if not all) cases of hell creek/Ojo Alamo “overlap”, and the few paleontologists I’ve managed to get to talk to about this have agreed with this sentiment. To anyone who has made it this far and read that novel I just wrote while sitting on the toilet, I appreciate you and I welcome any criticism or educated responses, just be civil please :). Good day 🥴

I think it's definitely an interesting topic so thank you for covering it! T.rex is my favourite dinosaur species of them all ever since I was younger. However the idea of it potentially hunting a behemoth like Alamosaurus is so cool, I think it's possible that southern populations of T.rex had maybe evolved slightly different hunting strategies perhaps to their northern populations who didn't co-exist with this sauropod. Maybe southern T.rex did form loose bands to try bring down adult Alamosaurus especially if they were smart enough to wait for say two males to fight and if one was injured battling another Alamosaurus? That individual is weakened and therefore a bit easier to take down. Although IF that did happen I imagine once such a kill was made which would probably take hours then it'd devolve into whoever is the strongest or biggest T.rex is eating first lol

Juveniles & Adolescents : Likely Adults : Only the suicidal ones

Giga took full dex build for a living while Rex is pure strength bonking with that skull and bulk. And ironically speedy build makes Giga a better sauropod hunter.

A trex would only hunt an alamosaurus if given a good opportunity (the individual is significantly injured, sick, or young). It doesn't have the skill set to hunt them regularly or take on individuals in good health. It doesn't have the same speed as other sauropod hunters, which is critical for avoiding attacks and getting in as many hits as possible in a short timeframe. Trex cannot tank or overpower a sauropod. It's bite isn't ideal either. The large volume of muscle and soft tissue makes a force based bite significantly less effective. It gets cushioned. Knifelike teeth are better for this as they can sheer through lots of softer material, and that's why giganotosaurus and others like it have those teeth. Combined with the difference in biting speed, a carcharodontosaurid would inflict much more damage on a sauropod than a rex would in a given period of time. The only way I see a rex killing a healthy alamosaurus is attacking the neck if it was really close to the ground for some reason.

I think the issue T. rex would face when it comes to adult sauropods is that there's no part of the animal it could even get its jaws around

southern hemisphere inhabitant showing southern hemisphere bias still good video lol

I would also mention that any rex trying to reach an Alamo neck will put itself point blank in front of the sauropod and guarantee to get trampled. A rex would likely have hunted Alamos small enough for it to bite their neck without needing to reach, but once they get large enough to where their neck are too high up to safety bite down on, the rex would leave them be.

Triceratops gave TRex a hard time,..those horns and rotating head, ouch, I'd love to know how many T Rex were injured or killed trying to tackle one, the numbers must have been huge.

PS- Edmontosaurus was no slouch and was close on 7-8 tonnes itself,; if growing to 12 or 13 metres long. It would be an adversary for any T.Rex. And the contemporary ceratopsians were formidable prey too.

I imagine they would scavenge from a sauropod or maybe even take out a younger here or there, but T-Rex versus a full grown Sauropod sounds awfully one sided

I think people forget that even triceratops and edmontosaurus probably gave trex a run for its money as 50% of trex specimens died 4 years or sooner after reaching adulthood

The young, ill,and dead Alamo would be ample targets for the rex, but the full grown, and healthy adults would be a bit too much. The size difference is just too much.

“The T-Rex being the definition of “That Guy””.

I could totally see them being opportunistic against elder ones in physical decline, a solid bite behind the leg would be game ending

I don't think even the biggest giganotosaurs preyed upon adult Sauropods in their prime

I see a lot of comments comparing t-rex's to lions... and sauropods to elephants, hippos and giraffes... but lions are pack hunters. The data we've found on t-rex's shows they were most likely loaner hunter/scavengers, more akin to grizzly bears or polar bears. It's not common at all for even a large grizzly boar to take on a bull moose or bull elk, but their young, sick, weak, or old... sure. I'm fairly certain that rex's filled the same sort of niche as a bear of today, eating whatever it came across, including small animals, fish, dead carcasses, perhaps even some vegetation occasionally... but it's not likely that they attacked sauropods very often unless they were young, sick, weak or old. They might have picked off stragglers while the herd ran away, but that'd be about it, even if they were pack hunters.

We also have to take into account that despite full size Alamosaurus were probably the minority of their species. It took DECADES for large dinosaurs to reach adulthood and most of them might not have made it that long (which might also explain the rarity of full size fossils). So, it would stand to reason that Rex did hunt them but primarily juveniles

Perosnally I appreciate that T-rex hunting Alamosaurus is probably a rarity, it probably did happen. It might not be particularly good at it, compared to more specialised carnivores, but it probably did. However.... Tarbosaurus lived alongside several species of sauropod and appeared to have at least some adaptations that made it better at sauropod hunting. In the case of T-rex, it might simply be the case that it and Alamosaurus just hadn't lived together long enough for the rex to adapt to sauropod hunting

According to half the dinosaur community, Trex couldn’t hunt anything that wasn’t sick or old Seeing this video made me imagine how angry those people are

I definitely agree. A healthy, peak Alamosaurus versus even a group of 5 healthy, peak Tyrannosaurus all willing to share the loot? This ain’t an MMORPG. The T.rexes would get flattened. They wouldn’t even bother hunting them. The only time they’d ever do such a thing is if the T.rexes were desperate and numerous enough. This is shown in modern day too, where an entire pride took down an elephant. But that is VERY rare and should be an outlier, not the norm.

Alamosaurus adults are about 30-40 tons on average, with the largest specimens reaching over 60 tons. Those would definitely be waaaaay too big and tall for T. Rex to hunt effectively. Any young Alamosaurus less than 20 tons? Totally different story.

Most of this could be said for the bison/wolf matchup. And yet individual wolves do occasionally hunt and kill bison on their own.

I think Prehistoric Planet 2 showed the most possible scenario, of _Tyrannosaurus_ scavenging on weakened or dead _Alamosaurus_ rather than actively hunting them. Though it would not be out of the realm of possibility that younger _Tyrannosaurus_ would probably be nest raiders during hatching season. But until we have proof of active predation on titanosaurs by tyrannosaurid in North America, what I mentioned will remain a speculation.

Tarbosaurus would’ve been a sauropod hunter too

It's unlikely a Rex could kill a healthy adult sauropod. But it's jaws I believe could be effective to some extent, maybe against sick, old, injured individuals. Or. The occassional lucky kill. By breaking or damaging the bones of a sauropods' legs, maybe the Rex could destabilize the sauropod and bring it to the ground... potentially, but that's just my idea.😅 However, you have raised many good points, and I enjoyed the video.

T Rex won't shy away from hunting younger individuals but adult specimens are the ones that T Rex wouldn't hunt but hatchlings and younger individuals in a similar mass of a T Rex are in the menu. The T Rex won't target adult individuals as any predator today.

Honestly man, I don't think any predator goes after the peak specimens of larger prey. They are always looking for the unlucky fella with a limp.

If my boy Allosaurus can do it, then i think enormous chicken can do it.

Let me add my speculation please: As far as I am informed, sauropods (i.e. Alamosaurus) only appeared at the very end of the dinosaur age in the native range of T-Rex. Whilst T-Rex was optimally adapted in hunting armored prey, I do believe that it might be equipped well enough to take on an Alamosaurus, perhaps with a different hunting tecnique than the giga. Maybe if the dinosaurs would have lived a few million years longer, we would have seen Rex subspcies specialised on hunting sauropods. The only thing that concerns me with my point is that the Rex has a well known high rotational speed, is however not the fastest runner; this might give it a crucial disadvantage in tackling massive sauropods.

They probably could have hunted sauropods but maybe when they're old and sickly

Personally as a former super dinosaur nerd I would say yes but probably not how people think. There is evidence nowadays to support the idea that many therapod dinos traveled in packs to combat the large herds many herbivores traveled in. So i can see T-Rex being able to prey on younger, diseased, or even scavenging on dead alamasaurs. However that said it probably was not first choice as far as prey items. Much like a lion taking on a elephant. Maybe.. if the lion is desperate or hungry enough but most of the time big no. Especially when there are other far easier prey items more readily available where the risk of bodily harm was greatly decreased. Even Gigas who lived much earlier had to be very strategic about how they took down much larger sauropods and they were built for it.

Is not unreasonable. There was never a carnivore that would hunt a adult big sauropod. But I don’t see why a t-Rex wouldn’t be hunted actively young alamosaurus around 10-15m long

The issue is going to be a complicated one. Largely because an adult Sauropod is going to be impervious to just about anything. And that is simply going to be a result of their own massive size. They had a lot of food... and to some degree, many Sauropods likely grew to large size with the expectation that that large size would then deter future attacks on it once it reaches that size... regardless of the weapons that its potential predators may have... As while Giganotosaurus may have sharper teeth and fast reflexes... that may not be perfect against the thick skin that Sauropods likely had. They may not have the armor of something like Ankylosaurus, but I'd find it probable that Sauropods likely had rather tough skin/scales in their own right... similar to how the skin of many modern Bovines can be tough. It's not going to be so thin that just any bite would trigger such hemorrhaging that it would bleed out to a nip on the side or on the outer sides of the legs... which would be the areas where Giganotosaurus would be most easily able to attack. And that would be where it's lighter and less bulky size would be a detriment if it came into a prolonged fight with a large Sauropod. It might be able to bite and wound the Sauropod, but it's lighter build would not be able to withstand any sort of counterblow that the Sauropod could deliver... while the Sauropod's sheer mass would be able to shrug off most bites unless the Giganotosaurus is able to get at an area where a major blood vessel is near the skin surface. It can't just dive in, take off an outer layer of flesh from the outside and expect the Sauropod to bleed out... or at least get so weak that it would fall down. And an adult Sauropod would know this... In this, I'd argue that Giganotosaurus, even if its build was better suited to attacking Sauropods than Tyrannosaurus, would not be able to attack an adult successfully unless it was in large numbers and thus could employ the sort of siege tactics that Lions, Wolves, and Hyenas use to exhaust or corner larger prey. Otherwise, they'd still be focusing on juveniles or young adults.

Alamosaurus sanjuanensis is comparable in size to Argentinosaurus.

Imagine the Rex with the Honey Badger’s attitude :|

I agree 100% that's why even in the Jurassic franchise they never put Rexy hunting any Brachis or apatasaurus or even Dreadnaughtus it's practically jumping the megalodon if they did that and wouldn't fit right 😂 unless if it was a young or sick sauropod

I agree. It's just not built to do so

The situation as it stands, is that we have strong pathological evidence for T rex hunting ceratopsians and duck billed dinosaurs, but none for them hunting sauropods. That doesn't mean that it didn't happen of course. Having taken your observations on board, I would be surprised if they didn't at least prey on the juveniles, from time to time.

I wouldn't put it off the table, in modern day even Giraffes are vulnerable to attacks from Crocodiles & Lions while drinking since they're necks are so close to the ground. Theoretically, I think a Tyrannosaurus could kill an Alamosaurus if it got a clean shot on the neck while the Sauropod was drinking which isn't that far-fetched. Adult Tyrannosaurs were ambush predators waiting along game trails & water sources for prey, so even an adult Alamosaurus might not be as invulnerable from predation as first thought.

Sauropods where long gone in North America by the time T-Rex arrived.

i'd say a sick titanosur wuld still win and i'm a rex fanboy

3:36 Tyrannosaurus Goat vs Fraudropod

I don’t think it is out of the question for a tyrannosaurus to take on a sauropod, but it would be only in extreme and dire circumstances. Lions today do take on elephants when it requires it for instance.

Yeah, despite me being a T-Rex fan and knowing that a Rex is currently estimated to be bigger than a Giganotosaurus, the latter's design seem more equipped to taking down a large sauropod. Especially with a group, bleeding damage and endurance seems like a better adaptation to kill much larger animals than bone crushing strength and agility.

I agree with what folks are saying about T-Rex and comparing it to Lions. Lions are top tier predators but won't take on a gealthy adult elephant. It's not worth the risk. I'm curious though. We know Gigas hunter sauropods but is there evidence that they hunted healthy adults of a size similar to Alamosaurus? Or did they also tackle sicker adults and juveniles?

Fun parallelisim of this today: elephants were hunted by lions once in the 90s in Savute National Park, but it's been assumed because of a drought in the area forced the lions to do so, which they wouldn't usually do.

I agree, tho, predators do weird/risky things sometines, and if there is a predator you cant tell what or what not to do, that would be T-rex 😂

It's interesting noticing how Tarbosaurus developed convergent traits with Carcharodontosaurids, by having a narrower skull and slightly slimmer build. But then again, evidence suggests Mongolian sauropods didn't grow nearly as large or long as Alamosaurus or Argentinosaurus. Even in very late Cretaceous Argentina, after Carcharodontosaurids disappeared, it's likely Megaraptorans took over their niche. With T-Rex and Alamo ? Probably only the juveniles hunted smaller or sick Alamos.

tbh I couldn't say that large Carcharodontosaurs like Giga and Mapusaruus hunted adult sauropods either. They were just too big, the risk of injury when trying to attack an animal many many times your own weight is off the scale. Attack the tail you risk getting whipped off your feet. Attack the legs and you risk getting outright trampled which would be fatal to literally any animal and the neck is just off-limits. Subadults and medium sauropods would have been more to their liking. Similarly, T-Rex stood no chance against an adult Alamosaurus, but juveniles would be slow and easy pickings.

People should imagine themselves hunting a cow with nothing but knife hands. Sure it is possible, but imagine the potential injuries you may get fighting that beast, especially if you have rabbits and sheep around the area.

Better tooic for discussion is rex bite force vs force needed to crush sauropod leg bones. 12 tons or rex hanging on to a broken front leg would bring any behemoth down. But as others have said with the lion/elephant comparison; likely not reasonable due to size disparity.

Alamosaurus feels so out of place in this environment, unlike many of it's relatives, it doesn't face saurpod-hunting theorpods, it shares it's environmenment with a wide variety of large amored and unarmored prey which are more appealing to said predators, any dead individuals would add more food in a relatively food rich environment, and just randomly appeared after the "saurpod exhile" in NA. TL;DR, it doesn't have a large impact on it's ecosystem except for more strain on the carrying capacity. I suppose elephants share a similar role to Alamosaurus, they don't really get hunted unless there's a pack of 20-30 lions chasing it down.

The modern equivilant would be lions or tigers preying on elephants, which does happen, these cats are basically the only predators of the elephant, but it's extremely rare, basically only weak individuals during desperate times.

There is a skeletal mount of these two side by side at the Perot Museum in my home state of Texas. The two skeletons standing right next to each other makes one thing very clear: T-Rex is huge, but it is DWARFED by Alamosaurus. So it's pretty damn obvious that there is no way whatsoever that a T-Rex could solo an Alamosaurus unless it was a really young or very sick individual. In other cases, I think what we'd be more likely to see is either a team of T-Rexes taking down an Alamosaurus (but being EXTREMELY cautious while doing so) or a scenario similar to what we see in Planet Dinosaur between the Mapusaurus and the Argentinosaurus: a T-Rex ripping off chunks of an Alamosaurus without actually killing it and basically "snacking" on it.

I bet they ate plenty of juvenile sauropods, along with anything they could find. Also, a large adult sauropod with its head literally in the clouds eating giant trees might be fairly easy to sneak up on for a Rex. If a rex got the jump, it could bite off a portion of its tail, get a good bite on a leg. Not a stretch to think that a Rex bite would be prone to infection. It could snack on the tail and follow the thing until it got weak.. Predators usually don’t go for the prime examples of a species. A lot comes down to opportunity, or the scarcity of it.

I feel the T-Rex wouldn't even of messed with sick sauropods. As even they could of been a threat and a risk. I think they would of definitely scavenged on a sauropod carcass for sure though.

I think they are like sharks, hunting big whales? Nope, but eat it while they already dead? Yes

I agree. I am huge T rex fan and I nearly always side with the Tyrant Lizard for fictional battles. This is just outta its element tho. Now I think if it saw a Juvi one, its ass is grass.

Given just how big some t rex got im sure some hunted young alamosaurus but with adults potentially being 100 feet or maybe even bigger i doubt they would go after an adult unless they were hunting as a pack and even then it wouldnt be easy taking down even just one full grown alamosaurus

I'd say the only way for a T.Rex to take down an adult Alamosaurus is to ambush it when it's drinking so it can actually get a hold of it's head or neck but even then it would have to be really desperate to try that and even then I'm not really sure if it would even work.

It's theorized that they hunted in packs. If that's true then it's not too far fetched. We've seen a pack of lions take down a fully grown girraffe.

Well Alamosaurus coexist with T-Rex in the southern part of T-Rex range, so they definitely could hunt them, although smaller ones, since large healthy bull Alamosaurus in an aggressive state similar to musth elephant would definitely solo a T-Rex, and a herd of smaller of female Alamosaurus would definitely be a tough one

The visual I have in my head mostly would be of adolescent and desperate Tyrannosaurus making the attempt. The best it could hope for is, as you say, going after young, old, sick, already dying, or disabled individuals. That being said, the desperate or naive Tyrannosaurus would certainly lose but if it settled for one bite of the arm and by some miracle managed to survive the encounter, it would have to stalk the Alamosaurus for a good while. Probably too long to see any results. If the Tyrannosaurus had company then the odds are better but these hypothetical encounters would be very few and far between at best.

I'm no expert, but I have to say that if Giganotosaurus was able to hunt Sauropods, then I don't see a reason why Tyrannosaurus couldn't achieve the same feat. Sure, one is more optimized than the other for this sort of thing, but Giganotosaurus had to have been able to do this with some degree of ease otherwise it wouldn't have adapted to hunting Sauropods the way it did. Tyrannosaurus wouldn't have had an easy time since it isn't optimized to hunt Sauropods, but you can still hammer a nail into a wall with a screw driver. I'd imagine T-Rex would simply have chosen not to bother with most Alamosaurus because of the effort much like Lions and Giraffe. T-Rex was no dummy, it had the intelligence comparable to many current day predators except it had a much longer life time to learn from. I'd imagine as you said, T-Rex was more of an opportunistic hunter who might decide that smaller weaker Alamosaur would make for easy feastings, but a full grown healthy Alamosaurus would require more specialized circumstances. I do think T-Rex has what it takes to get the job done though.

Im not overestimating trex because a sauropod is no joke, but t rex had certain degree of social interactions between individuals, so, thinking on a herd of t rexes taking down a sauropod biting their legs would be reasonable, instead of ripping of the veins, breaking tibias and tendons to make it fall.

I would assume like lions which rarely attack an adult healthy elephant but the young sauropods yes

All found bite marks by T. Rex are with juvenile dinosaurs. Thus, for so it appears that the tyrannosaurs were going after either weak or young dinosaurs.

Sharptooth vs Littlefoot's mother.

Hate to nitpick, but the wing bone proportions on your azhdarchid at 0:45 are grossly wrong.

Riley Black is a journalist. Not a paleontologist.

I'd add a thought: - Adamosaurus wasn't exactly big for a late titanosaur. If predation by a macropredator was a common occurence, it would probably have evolved to be larger.

What's interesting is that we have a Tyrannosaur that evolved traits similar to Charcarodontosaurids: Tarbosaurus. It had a lighter build, slimmer skill, slashing serrated teeth instead of bone crushing teeth, and about half the bite force of Tyrannosaurus. It was likely better equipped for hunting sauropods

pretty sure if it did hunt sauropods it wouldn’t really evolve the bone crushing strategy and instead adopt an more of like a bleed strategy

Seems like the kind of reason why lions don't routinely hunt hippos, rhinos, or elephants. Too risky unless they find a weak or young one.

i am not saying that i know if t rex was capable enough to take down a sauropod but there is this thing with its intelligense right? Some say primate level of intelligence.Maybe they used differrent strategies to take down bigger prey. Like some primates use tools to fish. Just a big guess.

Yeah t.rex eating sauropods well thats a no brainer, its like Kodiak bears coming across a beached whale.

It may have been able to IF it tore significant chunks out of the leg muscle or tendons. It would drop like a boulder.
