Exactly. You could add the sick or injured to that list. While their armor might be thick, a sick or injured adult, unable to fight back properly, would give the Rex plenty of time to flip it over.

[@ryanhau1073]

An interesting note. When compared to other Large Predatory Theropods, Tyrannosaurus Jaws and Teeth seem be specifically specialized to break through hard boney material, other large theropods like Giganotosaurus for example have jaws and teeth more for just slicing flesh. So it got me thinking, if T-Rex mostly just hunted Hadrosaurs and Ceratopsians, those Jaws seems like Extreme Overkill, so maybe there were some specific evolutionary pressure that Rexes would benefit greatly for Bone Breaking Jaws, like maybe Prey that is heavily armored

[@tuunaes]

Ability to crush bones would give access to quite energy rich bone marrow in addition to just softer parts of the kill. Also bone marrow would be available from carcasses, whose soft parts have been already more or less eaten by other weaker predators unable to break bones. Using its size T-rex was certainly able to take kills from other predators.

[@SpaceGodzilla-xb7vk]

Not really, pretty sure it’s too get access to bone marrow which makes the bones and muscles stronger when eaten, also your forgetting osteoderms are thicker and are also on the back, meaning less of a surface area to get the trexs jaws around, and if you use the 6-8 tons weight for the Anky, it’s lower to the ground and trying to flip it will lead to the club smashing into the trexs leg or head.

[@ryanhau1073]

@@SpaceGodzilla-xb7vk just think it's kinda interesting that Rexes did developed stronger jaws when compared to other similar sized theropod predators, like Carcharodontosaurs do seem to manage with jaws and teeth more specialized for slicing flesh, in fact it's believed that Acrocanthosaurus could take down large Sauropods. So it makes me wonder what in Tyrannosaur Evolutionary History would lead to these Overpowered Teeth and Jaws while other Theropods in similar niches really don't need it. In fact, some theorize that Bone Crushing Jaws may indicate T-Rex being more of a Scavenger, like getting into the bone marrow would be useful if the carcass the Rex found was already mostly eaten, tho those Jaws would also be useful in killing something quickly. Also if we going to compare modern animals. The Bear with the Weakest Bite Force is the Polar Bear, you know the one type of Bear that exclusively Eats Meat, while the Bear with the Strongest Bite Force is the Panda, as in the complete Herbivore, also Black and Brown Bears are somewhere in the middle. So it would lead me to speculate that T-Rexes might have a different type of diet when compared to other Mega Theropods

[@SpaceGodzilla-xb7vk]

@@ryanhau1073 ye so basically the stronger bites force means quicker kill times which means quicker meals and it snap bones which means they get more out of a meal, not just the flesh but also the bone marrow which is high in proteins, it was made for snapping bones in short. Not osteoderms however, those were likely made to counter strong bites, like an adaptation for herbivores and even some carnivores. It takes away all the force due to such a large surface area that the bite can’t even get around the whole thing, and it’s perfectly designed for the anky as when it goes for the back or tail it’s got that bone snapping club.

Rex was not a pokemon ready to square off and do battle with the toughest opponent it could find, face to face and fair. No predator does that.

Were Ankylosaurs herding animals? If so, I could see Rex’s hunting old or weakened ones, separating them from the group while avoiding the younger/stronger animals. They’d still be dangerous for sure, but it’d increase the likelihood that T-Rex hunted them.

[@jamesbyrd5175]

The best approximation to today is the tiger, the largest land based apex predator hypercarnivore alive. It's main prey is elk/sambar, gaur, and wild boar. The rough analogues would be hardasaurids= elk/sambar triceratops= boar ; not clear if Alamosaurus functioned like an Elephant (not prey) or a Gaur. The closest thing to an armored creature in tiger habitat is the indian rhino. Tigers don't normally prey on rhino, so that can lead credence to the they avoid anklos argument.

[@darinlunderman8063]

Given that it was the top carnivore of it's time as well as comparing it to how predators hunt in the modern era, the answer is obviously "yes". However, exactly how often a T. Rex might hunt an Ankylosaurus is the real question here. Predators like tigers will take down prey ranging from smaller to larger than itself, but they will more often hunt animals that are easier to kill to ensure a meal for the day. And so, I imagine T. Rex might hunt Ankylosaurus if there was less of it's usual prey around that gave less trouble.

[@williambuchanan77]

I'm guessing the T-Rex was wary of that tail. Why risk a serious injury to the leg when there was better, more easy options.

Tyrannosaurus was only unchallenged because no other large theropods lived alongside it, unlike every other large carnivore beforehand. But it technically hard as hard time as any predator as prey animals are dangerous or bloody fast.

Tbh it's most likely a T. Rex hunting an Ankylosaurus would be extremely rare and almost always end in failure. And if I remember correctly there actually is evidence of them encountering one another, with a rex having a broken leg that seemed to match up with getting hit by the club. There's theories that Anky's would've been extremely aggressive and attacked virtually anything that they see, so chances are they went right at any Rex's they saw and they likely fled.

[@tommyflo146]

I wonder if sub adults or juveniles would potentially have a better chance since they are faster, agile and lower to the ground than the adults

[@EddieCauseWhyNot]

Being accurate, it’s very possible that the t. Rex did hunt the anklyosaurus, definitely not often though. It wouldn’t usually be a fight like in a Jurassic world movie, the the T. rex would be a skilled ambush predator possibly hiding in bushes or near trees, and there’s also evidence that the T. rex made little to no sound when it was walking/ running due to soft plating on the bottom of the foot. Another thing is that the t. Rex wouldnt roar in this ambush which adds points of stealth. So if the T. rex ambushed the anklyo, it would almost 100% secure the kill. There’s still a pretty good chance it would secure a kill if they were put in an arena to fight, but an anklyo saurus would also have a pretty good shot at beating the tyranosaurus due to its armor and clubbed tail. So overall, it’s very possible the the T. rex would have hunted the anklyo saurus, but definitely not often to to it actually being pretty powerful and a threat to the T. rex if it had to fight it due to the anklyo actually being able to kill it due to the club and armor.

[@densincomprehend8879]

Im pretty sure it's not worth the risk because even if they do a successful hunt I'm pretty sure it didn't provide enough meat due to most of the pounds being armor.

I could imagine a mating pair of rexes with adolescent offspring surrounding an isolated ankylosaurus. The Ankylosaurus can not effectively defend from all angles without getting it's front/head exposed. Though risky the chances of a Rex making a kill increases substantially than a lone ranger. I personally believe Rexes raised their young like modern archesaurs do such as birds and crocodilians. Sometimes bird will raise offspring almost as big as themselves, though they'd probably leave when puberty kicks in. Younger tyrannosauruses will probably not like Mum and Dad stealling their kill and eventually leave.

But more importantly, a hit from its clubbed tail could break its femur or another leg bone, essentially killing the T. rex. A broken leg means it can’t hunt.

So if Ceratops line up with their horns facing out like a phalanx because their head is their weapon, it's very likely that since the weapon of the Anky was it's tail they would face fair foe with their hindquarters up and bracing with their front legs reverse of a Triceratops. In theory, if the Rex could get around that tail to the head then absolutely the fight is over because the skull plating would be much weaker than the body plating but the agility the Anky likely has to utilize it's body would have been difficult. Venturing an educated guess the Rex would have done like most modern predators we can observe today do... go for the young and weak BEFORE going for the strong and healthy. If they came across a group that didn't have anything that looked like easy pickings they'd have surely moved on to something more manageable.

Very likely T Rex hunted young and ill prey mostly. Young triceratops with small horns or old lame ones. It's well designed for hadrosaurs though and that's probably what it sought out the most. Very large T Rex specimens probably didn't really hunt, they could walk up to any carcass or recently killed animal and just take it. And they couldn't have had any agility at that size.

We have evidence of predatory-prey relationships between T-Rex and most other inhabitants of it's ecosystem; triceratops, edmontasaurus, etc. We don't have any evidence of them hunting ankylosaurus, and there is good reason for that. Look at modern predators, like the lion, tiger, wolf, hyena, etc. None of them hunt hunt turtles, lions get curious, but don't actively try to eat them. None of these animals actively hunt the largest strongest herbivores in their ecosystem. A pride of lions is not going to take on a healthy adult rhino, hippo, elephant or cape buffalo. They might go for a juvenile, a sick, or aging individual, but there has to be some weakness they can exploit to take on these creatures... and on the flip side none of those are armored like an ankylosaur or have a tail club that can end your entire life in one quick swing. For all of them; the dangerous parts are at the front. Ankylosaurus was clearly evolved to thwart attacks from predators, and it's likely why the only consistent injuries we see on them appear to be from interspecies conflicts; ankys smacking ankys. We have evidence of allosaurus hunting stegosaurus, and we have a lot of evidence of stegosaurus winning those battles. Many allosaurus skeletons have puncture marks consistent with stegosaurus's thagomizers (tail spikes) that have no bone growth; meaning they died as a result of that injury. We theorize that ankys had the ability to wind their tail up and swing with their body as they stepped away, like we believe stegosaurus did. It's like that stegosaurus, and it's relatives, were just on the cusp of "to eat or not to eat", and likely ingrained in the theropods of their environment that they should not be eaten. So when they evolved into even more armored dinosaurs, such ankylosaurs and nodosaurs, the theropds had gotten the message. "Eat at your own peril."

Apceros is very easy prey for a Deviljho.

[@Gojieditz57]

Wrong abt strongest jaws megalodon has the best bite force

[@TheOverseerDebates]

True but I did specify strongest jaws to walk our planet, so strongest terrestrial jaws.

[@N8-0]

But what if the ankylosaurus tasted better?

[@TheOverseerDebates]

Now that's a valid question

Cow sized immatures would have been an easier and commoner meal. We need to stop assuming these interactions were between full adults. If orcas and great white sharks commonly make meals of animals quite a bit smaller than them, same for the rex.

[@Ulitma_iLLustrated]

I'm committing this before watching the video and my comment may change I am guessing a full grown trex could hunt a full grown ankylosaur would be risking but feasible but it probably went for the young individuals In that case juvenials sub adults trex had the mind to think and analyze and stay out of range of the tail and It was agile enough to get to the front of the animal but this is talking in the sense of a fight a confrontation T rex was most likely an ambush predator sneaking up to a large ankylosaur is easy because of the poor eye sight even more easy at night burst out crush the head

Talk faster and run everything together with hardly any pauses please.

If Tyrannosaurus could rip off a Triceratops' head, then I'm sure one can bite off the tail of an Ankylosaurus.

[@AlexRamey-l2j]

T rex is still the most powerful dinosaur predator and the true king of the dinosaurs

[@Thulgore]

Why is there nothing approaching a decent ankylosaur model? No one seems to have pictured the animal the same.

[@andy-the-gardener]

the ankylosaurs tail club is yet another boring example of the drive to downplay animal features that are obviously martial to merely sexual display features. must. make. animals. progressive! other examples are the lions mane, and the stegosaurs back plates. the latter are commonly said to be too fragile to be weapons. but even relatively fragile plates would cause damage to a predator when the incredibly powerful animal violently rotated on its hind limbs like a wirling dervish spinning top to attempt a tail strike. if theres a place an allosaur would target is the back, to avoid the tail. it was a weak spot. the plates were obviously there to defeat that strategy. the problem with the 'they were just used socially' is the existence of massive hyper warm blooded predatory dinosaurs. if they didnt exist then, yeah it would be a reasonable claim. but otherwise its just silly

[@Jeffery3464]

I agree they keep down playing dinos and animals even today like saying the Pachycephalosaurus couldn't use it head to defend itself, how can one look at a massive bone club and say no it was only used for mating display. Even if it was you can sure as hell bet the dino would still use it in combat lol.

[@bkjeong4302]

The big issue for a Rex trying to hunt an Anky is the issue of how broad the latter is, which (when combined with the fact Rex’s *effective* maximum gape-the upper limit at which it can bite down and deploy its bite force-is 45 degrees) means that unless it’s going for the head or the tail, a Rex is going to have to open its mouth to its absolute maximum limit to even fit an anky’s torso in its mouth, and as with all tetrapods Rex couldn’t apply the force of its jaw muscles to a significant extent when its jaws were extended to the limit. Some theropods (looking at you allosauroids) got around this limit by using their neck muscles (which aren’t subject to this limitation) to move the upper jaw vertically so that the lower jaw and jaw muscles would only need to provide leverage while the neck pushed the upper jaw down towards the lower jaw. But Tyrannosaurus’s neck was instead adapted for thrashing its head from side to side to overpower prey it was biting into, meaning it can’t do what the allosauroids did to get around the limitations of tetrapod skull anatomy. With the tail being very well-defended the one place left to bite down on is the completely armoured head.

[@barbatoslupusrex8712]

The hatchet bite theory for allosaurus has already been debunked sadly. So that explanation doesn’t apply.

[@bkjeong4302]

@@barbatoslupusrex8712 I never said anything about the hatchet bite, I specified that BOTH the upper and lower jaw would be biting (in the hatchet bite the lower jaw does nothing). The neck adaptations are still very much real, just used differently (the neck and upper jaw would be cutting into stuff that was braced against the lower jaw instead of just vertically slamming) So my explanation DOES still apply.

[@bkjeong4302]

@dinofiles I’m not trying to “one-up” them; I’m trying to deal with the fact basically every tyrannosaur video makes them look “inferior” in comparison.

[@rodrigopinto6676]

bkjeong4302 wrong arguments 😂😂😂

[@bkjeong4302]

@dinofiles There has never been a time when Tyrannosaurus was seen as a “lesser” theropod; even when other giant theropods rivalling it were discovered it was still routinely being argued to be the “superior” killing machine by people who praised only its adaptations and not those of the OTHER giant predatory theropods, which is the issue at hand here. The reason Tyrannosaurus is seen as the “superior” theropod is not because of its adaptations but because of the misperception that other theropods didn’t have any advantages in their own right and were thus “worse” at killing other animals. What they lack in robustness or jaw power they make up for with wider gapes (both maximum and effective maximum gape), sharper teeth, and the added power of their neck muscles (specifically on the vertical plane, so that their effective bite force is that + their on-paper bite force that only accounts for the jaw muscles, and again this is not the same as the hatchet bite which ignored the lower jaw entirely). But tyrannosaur fans pretend these features weren’t relevant to argue Tyrannosaurus was way better at killing things. There is every reason to doubt that Tyrannosaurus was more intelligent than non-coelurosaurian theropods when crocodilians are already capable of matching many birds in brainpower WITHOUT “evolved” or larger brains (before you mention corvids and parrots: those are massive outliers).
