The Dinosaur That Gave T-Rex Nightmares...

[@williambuchanan77]

I think T-Rexes would have only one reaction to raptors, search and destroy. There's no way they would have tolerated them as they were a danger to young T-Rex's. Even a group of Raptors would have kept a distance from T-rex's for this reason. They were massive but T-Rex's were quite nimble. Their bones showed they fought with each other frequently which points towards them having a violent nature and were not to be messed with. That being said, a Triceratops stampede must've been something awesome to witness.

T-Rex was not afraid of Triceratops. For certain, triceratops was a fearsome animal to try and take down… even for the Rex… but the Rex did hunt triceratops. Fact. How do we know this? In 2006 a fossil was discovered on a Montana ranch. The fossil contained two animals: a triceratops and a T-Rex. They were literally, locked in a death struggle, when they were killed together by a massive mud slide (or landslide). Buried under tons of material, they died together, still locked in their fight. The triceratops had one of T-Rex’s ankles in its mouth. The T-Rex’s other leg was jammed behind triceratops huge, bony head plate, where it’s claws were lodged in the ‘top’s neck. The Rex was missing some teeth and had some minor fractures. The Rex’s teeth were stuck in the ‘tops spine. The ‘tops also had a pelvic fracture. This extraordinary fossil has been affectionately called “duelling dinosaurs” by the paleontology community. The fossil matter of factly ends the debate over whether or not Rex was a scavenger or a fearsome hunter. The existence of the fossil demonstrates once and for all that Rex was a fighter that actively attacked and killed its prey, regardless of said prey’s size or disposition. It also demonstrates the fact that ‘tops was spirited beast that was capable of inflicting serious injury upon its predators. Regardless, given the wounds of the two animals, Rex was winning the fight when they were suddenly buried. The fossil has finally been brought out and prepared for exhibition to the public. It is headed for the North Carolina Museum of Natural Science. So while Rex might have had to work hard to take down Triceratops… and would likely pay for that meal with some painful wounds, clearly Rex wasn’t afraid of them.

[@carolynallisee2463]

As I watched this, I pondered upon something the first section of the video made me think about. This is that, for all the detail the fossilised bones can give us about the animal in question, the bones can very seldom shed light on aspects of behaviour. The narrator talked about how modern African Elephants, being the largest land living mammals, aren't targeted by predators. Yet, a few years ago, a BBC Natural History Unit documented how a pride of lions learned how to hunt, bring down and kill elephants, a survival tactic the pride employed when easier pray had become scarce. The thing is, two different generations employed this skill several years apart, during two difficult seasons for the pride. I hate to use the words 'custom' and 'tradition' because they're too anthropomorphic, but I can't find anything that fits better. So what does it have to do with T-Rex and my earlier statement about fossil bones being unable to give many behavioural clues? Well, bones alone can't tell us just how the dinos lived. It's always been assumed that carnivorous dinosaurs were solitary livers and hunters, but the truth is that we just don't know for certain. Every now and again, suggestions are made for this or that carnivorous species to live in pairs or packs. Again, the fossilised remains can give little or no evidence either way. Given that cat species show the whole range of co-habitation systems from solitary to group living, it wouldn't surprise me if carnivorous dinos did the same, with size having no effect on living arrangements. Nor would it surprise me to learn that sauropods weren't as immune to predation as has been suggested. All it would take would be a scarcity of regular prey and a desperate group of T-Rexes, and we'd have the Mesozoic equivalent of elephant hunting Lions!

[@isaacA38]

yea but as you stated. Its not a common thing to happen. Its 99,9% guaranteed that these things happened, but we have no prove for it. Lions also usually stay far away from adult elephants. And a lot of lions die in the desperate attempt to kill an elephant. So although i agree with you that this scenario accured it was not a normal thing for the average trex. But i can imagine that some specialized on dangerous prey, which is a common trade in orcas for example

[@babystacks]

@@babystacks yea no shit sherlock. I was guessing as well.

[@normanchodrick2630]

I would assume that the lions attempting to predate an elephant or any Raptors or T-Rexs attempting to take down Sauropods would have concentrated on the heels or upper back of the legs to 'hamstring' those preys which is what dogs do 'nipping at the heels' and African poachers do to bring elephants down. The poachers use traps that wrap wire around the upper heel area to cut into and sever the hamstring hamstringing elephants over that bit of time it takes for the wire to cut thru far enough. A hamstrung animal would be a fallen animal incapable of much of any defense of any type. The very large Sauropods would likely have been too much trouble to bite thru all that leg material for anything smaller than, say, a T-Rex, but being inside away from the tail under the tail working on the hind leg(s)they could likely have done so 'IF' T-Rexs were as smart as Raptors supposedly were or dogs ARE.

[@JohnJ469]

We're now pretty sure they were family/pack animals. A bunch of fossils were found in Canada a few years ago. There were recently hatched, through juveniles to fully grown all found in the same place. Sorry but I can't think of more details beyond that.

[@TyrannoWright]

To put it short, prey animals of tyrannosaurus in general were not easy to access since most of them were prepared just as well; be it for flight or fight. If it isn't the prey that doesn't deter a rex, it's competition with another rex that will.

While not likely quite the 'nightmare' to T-Rex or raptors or predators in general, I feel Sauropods are overlooked for having 'defensive' capabilities because it is considered that their size was their protection and defense, but consider that they were not always that big but grew to those very large sized. I think that their main weapon would have been their tails used as whips. A very large Sauropod's use of its tail as a whip might could have broken fully grown T-Rex legs, tails, ribs and necks or just have blasted Raptors to pieces in defense of themselves and their young-as how the young were even able to survive at all. Sauropods like should have a fairly hard but somewhat flexible covering on the ends of their tails to prevent the ends of their own tails from also being blasted to pieces from such use.

A 15th century man-at-arms or knight could have solved the Ankylosaurus riddle had one lived 650 years. Once blacksmiths could produce hardenable steel plate in significant quantities, melee weapons without serious percussive potential or powerful piercing points plummeted in efficacy. It requires either extremely high speed, or high mass and inertia with a focusing face or spike to harm a wearer through it. This is why we see very large hammers, picks, spikes, or axes on much longer poles instead of spears, cutting spears/glaives, long axes as in the 9th to 12th centuries. Stegosaurus' tail with 14"+ long spikes is probably a much better anti predator device, causing serious wounds with less force, being able to be deployed more quickly because it's less massive, and as a lighter weight on the end of a flexible lever disturb the gait less with induced motion as it bounces with each step. Against a slow opponent wearing heavy plates however, a giant maul or hammer is devastating and can either defeat armor or just transmit the force right through it into vulnerable tissue below if a blow lands near softer fatty tissue like liver/brain.

[@m3lvn415]

I think the T-rex only hunted the smaller/young Triceratops or feast on carcasses. Like modern predators. The injuries were just failed attempts.

[@smgdfcmfah]

Honestly, even agile, horned animals need to be FAR larger than the predators they share territory with before they stop being prey - especially with pack animals. Bison, buffalo, muskox, moose - all are far larger than the animals that prey on them. Full grown giraffes, hippos, rhinos and elephants are the only animals relatively safe from the far smaller lions - and occasionally even they run into issues if the lions are desperate. For this reason I doubt any dinosaur other than certain sauropods had any hope of being immune to assault from theropods. After all, it's the theropods that evolved and still exist today!

[@craigsurbrook5702]

Yes, yes, I'm sure Tyrannosaurs were just fearful of all these other dinosaurs, instead of these other dinosaurs being terrified of being eaten by Trex predators.

No. According to fossil records adult edmontosaurs were regularly successfully preyed upon by Rex.

[@giri_2003]

@@Someguy12796 Yes that's right. Rexes are successful in preying adult edmontosaurs but that doesn't mean that they are easy preys. Edmontosaurus are similar to modern zebras, though lions successfully hunt zebras, lions have risk to get beaten by zebras powerful kicks. Then edmontosaurus it's kick including with large tails can fight back the t rex, adults were average of 12 metres long and 9 tonnes weight. Even t rexes knows very well about the risks of hunting these adult hadrosaurs. Untill it dies, it does everything to survive like biting, kicking, ramming, tail swiping,etc... which means they use whole body as a weapon. Even the large hadrosaurs which are 13-15 metres long and 10-15 tonnes can crush the t rex by using it's body. EDMONTOSAURUS ARE HIGHLY UNDERRATED PREYS OF TYRANNOSAURUS REX

[@giri_2003]

@@IRNHYD Yes, that's right. Rexes were able to take down these large ceratopsids but these smartest predators know what are the risks in this hunt. Triceratops were average of 30 feet long, 10 feet tall at frill and weighs around 10 tonnes. These ceratopsids were abnormally agile, answering why t rex evolved into highly agile predator (All this period dinosaurs from this particular niches were highly agile). Tric can actually kill a t rex or atleast cause severe injuries before dies when there is a straight combat, so the t rex hunts the trics by ambushing themselves and complete the hunt within the tric notice the predator. Compare this hunt to modern life lions and cape buffaloes, even a single healthy lion can beat this prey successful but it doesn't mean that this is easy prey.

T-rex was built to run faster than prey animals, had binocular vision, and was the largest carnivore of the time.

Most scavengers are built smaller than predators.

[@sasa1982uk]

@ce6654 good points, what about the teeth? Teeth only for shredding and combining the teeth with the lack of arms and toe claws to hold its prey it wont be hunting anything that can put up any sort of real fight, its teeth design is meant to take big bites of meat as quick as possible. its size, it can't sneak up on its prey, or run at speed for a long time, which narrows its prey to big lumbering dinosaurs, big risk without the correct teeth or claws of any kind to fight or hold prey of that size down. it's size could be used to scare off other scavengers. It's smell and eyes are to locate carcasses.

A large predator like a TRex might reconsider its attack under that kind of threat. Ankyla's tail could mess them up permanently.

Incorrect. T-Rex hunted, fought with and took down triceratiops. The fossil, affectionately referred to the campaignto as “the missing cart”.

[@IRNHYD]

Nah. A fossil was found in Montana in 2006. A Triceratops and a T-Rex, found locked, fossilized, in their death struggle. The ‘Tops had Rex’s tail clamped in its mouth. It also had some of the Rex’s teeth stuck in its spine and a fractured pelvis. The Rex was missing some of its teeth (found in ‘tops spine) and had a couple of small fractures. The Rex had one of its clawed toes jammed behind the ‘Tops bony armored skull plate, where the toes were jammed into the ‘Tops neck. Clearly, Triceratops was a beast that put up a good fight, as the Rex had a few injuries and lost some teeth. But the fact that these two animals got fossilized while fighting (it was a mudslide that buried them) demonstrates that this very scene played out all the time in the Hell Creek formation. … which was a hotspot for Dino activity and paleontologists say it “fairly crawled with Tyrannosaurs”.

T-Rex Would Of Had A Hell Of A Time Against A Spinosaurus.

[@Bellthorian]

I think they have it all wrong when talking about hypothetical encounters between T-Rex and Alamosaurus. T-Rex teeth had grooves on the backside of the teeth where food would decay and form bacteria colonies much like todays Komodo Dragon. I believe T-Rex would wait in ambush position, charge out and try for an initial bite and than simply back off. A T-Rex could remove as much as 500 pounds of flesh in a single bite and with a wound that big there was always a chance of an animal dying from blood loss. If it didn't infection would set in and the Alamosaurus would be fighting for its life that way. This is where I believe the massive olfactory senses of the T-Rex came into play, it would track the animal it bit through the fresh blood smell and later the smell of infected tissue, keeping a safe distance, being patient. It would wait for the Alamosaurus to get separated from its herd and die from either blood loss or infection and than the T-Rex would have a meal that would last for DAYS, maybe a week. Physically battling is a prey animal that large would be suicide so I think as the evolutionary arms race between predator and prey escalated in size, I believe hunting tactics would have had to have evolved as well and T-Rex's mouth would be the perfect weapon to deliver fatal bites to intended prey.

With so many giant beasts around T Rex need seldom have hunted anything dangerous. Enough of these giant herbivorous beasts would be dying naturally for it to pick off the sick, dying and dead - or just the juveniles.

I doubt the T Rex would do this under normal circumstances. There were enough easy meals around.

[@N.Sniper]

Triceratops horns were very NOT DELICATE but very strong. They were made of solid bone and covered with keratine. A Tyrannosaurus Rex would not go after a healthy adult Triceratops. Only young or sick. And if possible avoid them all together and go for a hadrosaur. A blow with Ankylosaurus club to the leg of a Rex and its leg would be broken. Which means the end, since it could no longer feed itself. Dakotaraptor would only be a danger to young Rexes. Even in packs, a Rex, Trike or Anky would just be to big and to armed.

[@IRNHYD]

No. The myth of T-Rex being a scavenger has been permanently laid to rest. In 2006 a fossil was found in Montana. A T-Rex and a Triceratops, who both were suddenly buried while they were locked in a death struggle. The Triceratops had Rex’s tail clamped firmly in its mouth. A number of Rex’s teeth were lodges in its spine. ‘tops also had a fractured pelvis. Rex was missing a few teeth (those stuck in ‘tops back), had a few small fractures and one of its feet was jammed up behind the ‘Tops bony skull plate, with its clawed toes jammed in ‘tops neck. With the likelihood of fossilization occurring being a tiny fraction of bones, among the whole population, the fact that these two died like that demonstrates that Rex was truly the master of its domain. Not some scavenger. The fossil is at a museum in NC. They refer to it as the “dueling Dino’s fossil”.

@@IRNHYD @TyrannusX Ya'll clearly need your religion of evolution and television (tell-a-vision) PROGRAMMING to be an absolute fact in order for you to exist it seems. Programming I say again. Propagandized Programming to engineer the general averaged opinions of the masses for the social engineers paradigm of vailed total control. Millions of years is Propaganda BS. These critters were Suddenly BURRIED as IRNHYD said, but it was only a few thousand years ago in a global cataclysm. Soft Tissue as they had also found in T-Rex Bones could not remain after Millions of years. In a mud-flood or tidal waves they burried millions of big lizard critters in mass graves.

my favorite is the Family Guy T-Rex

[@BradBalch]

I really hate the “scientists say this weapon was just for display/mating rights BUT if a predator comes along…”. I, a moron, feel like they developed that shit for anytime shit got serious, fighting, fuckin or flexin.

[@MisterTee]

T-Rex was never cautious and don’t call me Shirley

[@mobileplayers5008]

This Dino give t rex a hell run. But who care it was all over

[@roy19491]

there are those who believe the T Rex to be a scavenger, rather than a true predator

[@Spiritkill1]

What about Deinosuchus.

[@nialllambert3194]

Who wrote this? A 12 year old? "Triceratops is SYNONYMOUS with T-Rex"? That's equivalent to saying that John Lennon has the same name as Elvis Presley.

[@nickolisgreen4428]

We learned in school about the beef between the two so yeah it’s synonymous.

[@kwokleongawyong1064]

Think elephants, rhino vs lion

[@Spiritkill1]

From water Deinosuchus

[@bornr2797]

The titanic...150 tons of steel in a few more years will be a rust stain...thats bout 150 years or less!!!...millions of years???..common people

[@Letnothinggotowaste]

T Rex was a scavenger, not a predator. Look at front limbs. Scavenger build like racoons ..

[@RobertWinjum]

None of them survived. That's all that really matters

[@michaelphillips3123]

No Stegasaurus?

[@anthonymorales8510]

Stegosaurus was in the jurassic period. By the time T-Rex was around (late Cretaceous) the stegosaurus was long since extinct.

[@Pardogad]

Brachio is my favorite but hail the king tyrannosaurus

[@bornr2797]

Dumbest thing ever is the thought that idiots think a bone or ANYTHING in the world can last 65 mill years...

[@donaldthetruthseeker-es3nu]

No one knows, they are extinct and anyone that did such a creature is been dead a long time ago.
