Because Science Could you please do an episode of because science on spinosaurus versus Tyrannosaurus rex For several reasons : 1) they didn’t even exist at the same time . 2) they weren’t even on the same continent 3) Spinosaurus jaw was made to eat fish 4) and would have been far too weak to bite at Tyrannosaurus rex neck and fling it 10 feet away I understand that the movie Jurassic Park III put it in there for entertainment value but people on KZbin are talking about it like they could be some believability to this so could you please, I’m begging please rectify this Yours truly an avid watcher of your channel by the way I remember when you had shorthair thanks much Richard Parks

Ever since I studied some engineering, I've always been extra fascinated by the massive complications dinosaurs must have dealt with to be so massive. Look at elephants, which stand more or less on their toes, and can't jump. I was a bit surprised to realize that a fall would be very lethal to the larger dinosaurs. I wonder what their fights would have been like, with their limitations in mind? If two t-rexi fought over territory, if one got knocked over, this would probably have been lethal, and if they preferred posturing more over shows of actual strength. If one good blow could mean death, it'd be a bad idea to pick fights I suppose!

[@novakivanovic5987]

best coment 10/10

[@3vrLol]

The tail of a T-Rex was probably used to balance that massive top-weight of the animal. If so, it would also be very strong, and as you have illustrated very well (this is probably the best visualization on dinosaur size I've seen in a while) it is also incredibly long. Combining those two facts, coming up behind a T-Rex in order to mess around with its legs might be just as dangerous (if not more so) as coming at it from the front, since just one sweep with that massive tail would be enough to send you flying several feet and crush your body into paste.

[@manekou3303]

3vrLol and even if you get there you might still get stomped.

[@CoyoteCamouflage]

Oddly, I think the T-Rex's size still plays against it. As Kyle demonstrated, the tail itself is quite high off the ground, and given the amounts of balance that such a large creature would require, I'm not sure that it could actively utilize it's tail very well against a small, low-to-the-ground target. Not that you wouldn't be smooshed with one hit. Rather, I think that the range of motion required to use the tail as a weapon beyond a little coincidental wiggle-waggle would cause enough torque to tear the Rex's hips apart. Is it a danger? Absolutely, but I definitely think it's much less "actively" dangerous than the front end.

[@JohnA...]

I agree. It might still be a bit dangerous, but its probably so important to the balance of the animal that it wouldn't be able to effectively use it as any sort of weapon against something intentionally without also having to worry about tipping over itself, thus negating any effective use of it as a weapon, and more just an obstacle to avoid.

[@doratheexploder286]

Monitor lizards are 4 legged, not bi-pedals like Rexxie.

[@ninjahombrepalito1721]

You need to think about this. Bears fight wolves. Tigers fight wild dogs. There were smaller predators that T-rex competed with and probably fought from time to time. It probably was formidable defending itself. T-rex ruled for millions of years. It was probably not as fragile as this video suggests.

[@ironicdutchmoonshade1394]

Not only do you have to be a good sprinter, you have to be a long distance sprinter since a T-Rex probably won't give up after 100 meters.

[@becausescience]

Exactly -- KH

[@valkorionthegreat6066]

Would he really? I mean, a human seems to be almost too small to be considered an "interesting" prey. Most predators don't chase after what they don't consider "worth the hassle", because they need to save their energy as most as they can - they can't afford any waste. My dinosaur knowledge is extremely rusty, so I'm honestly curious. Wouldn't it be more logical for the T-Rex to just scare off small animals he's not interested in eating?

[@ironicdutchmoonshade1394]

Valkorion the Great I don't know much about this either, but I guess it depends on how hungry it is and how many bigger animals are close

For the sword option I'd use a greatsword-sized falchion, give it to my strongest guy, and have him do a wrath cut to the tendons to maximize the chance of success. For the mass of the greatsword would give the cut bite, and the edge geometry of the falchion would make it able to slice as effortlessly into flesh as your razor shaves hair. The strength of the wielder would provide lots of force and the wrath cut, focused on one powerful strike, would best focus that force on the fine razor-edge of the blade to devastate the T-Rex. Also, I's have a distraction keeping the T-Rex occupied from the puny human sneaking behind it to sever its tendons.

[@tiagomatos6962]

Next video: "Why you would need to know how fight a T-Rex, and win"

[@MichaelBerthelsen]

What tensile strength would you need your tripwire to have, in order for it to not snap when being exposed to a sprinting T-rex hitting it with one leg first, accelerating forward? And is this a realistic force for vines to have, since that's what would most likely be available?

[@JohnA...]

A decent steal cable would probably be sufficient enough to not snap, but your would have to tie it to something that it wouldn't also just break or somehow come lose from. Though we are talking about something that is exceptionally top heavy, so just a small force applied to unbalance it would probably be enough to accomplish the task even if it did come loose or break in the process.

[@kfrews]

Also it could break, all it has to do is cause a misstep breaking the stride and causing momentum to topple the beast. The balance point is so precise any disruption could be catastrophic.

[@blazedgamingkr1438]

An arresting cable from an aircraft carrier, like the Eisenhower CVN69, should work just fine without snapping. As Kyle said in the video, T-Rex would be lucky to "sprint" at all. So you would only have to topple it's mass at 11mph. Which is made easier by it being extremely top heavy.

[@moviemaker2011z]

steel cables or even a regular heavy duty chain would be about in the ballpark. like kyle said its top heavy and might be easy to tip over. so even if the chain snapped in half it would probably have been enough to make the T-rex lose its footing and likely trip it giving you plenty of time to try and cut the heels or run even further.

[@magicalmacaw]

Michael Berthelsen You would certainly need to wrap it around several times which means it would be visible and easily stepped over. But if you can figure out the whole time travel thing you could probably figure out high to take some strong yet hard to see wiring back with you; or an elephant gun. 🤣

[@TheHornedKing]

First, I wanna say I love how you included the discoveries of recent years, like it having feathers, and how good eyesight it actually had. And for my question; Do you think you could you distract it with something like a flare, or some other kind of light? Would that be effective?

[@CoyoteCamouflage]

The distraction should be possible, in the same way that a laser pointer works on felines. A person holding a flare-- particularly in Grant's case, where it is very dark and his physical form is obscured from the predator by heavy rainfall, shouldn't have much issue getting a predator to focus in on a flare-- a distinct oddity that could be something edible. The Rex itself is likely very unused to things like flares, and with the bright red light sparking up in the middle of a storm, it could definitely be more of a focus than the person holding it.

[@seanpeery7780]

A big factor that Kyle forgot to mention is that T-Rex's are both predators and scavengers. They likely sought very large prey, given hint to by the overkill that their bit force would have against smaller animals like ourselves. The articulation of movement a T-Rex posses is so poor that if you managed to get near the rear of their feet there would be nothing that they could do to get to you. If they attempted to deliberately step on you, they would throw off their balance trying to raise their foot 2m off the ground without forward momentum. In reality a T-Rex would be easier to hunt than an Elephant due to the fact that it is reliance on its forward motion for stability, since it only has two legs as opposed to four; meaning that as soon as you were behind it, it would be helpless against you (aside from its tails random movements). One hunter in front and one behind with spears would leave the Rex with limited options, face the front person who can easily keep their distance while the rear is stabbed multiple times, turn to face the rear simply reversing the problem, or charge/flee where its maneuverability becomes limited and a fit enough couple of humans could not only keep pace but *easily* outlast the dino in a test of stamina. Hunter class humans would do incredibly well in a matchup against what movies try to tell us would be terrifying, when in reality a cougar is a significantly more dangerous threat than nearly any dinosaur that existed. T-Rex weaknesses: Slow speed up and low top speed, limited stability from being bipedal, inability to turn rapidly, inability to access areas smaller than its beak, stride length, forward heavy center of mass. We wouldn't be hunted by the T-Rex, we would be hunting T-Rex and people would be filming KZbin videos of themselves trying to take these down with knives.

[@KurNorock]

Sean Peery I bet you are one of those people that thinks they would be better off in a medieval battle without armor right? You couldn't be more wrong about trex.

[@argr4sh]

though I do think that the idea of people taking out T-rex's out with knives is a bit of an exaggeration to say the least, he does have a point. These beasts were never meant to kill smaller nimble creatures, instead they went for other beasts equal, or even larger in size. this means they aren't optimised for fighting humans to say the least. For them, fighting humans would be like what for us is hitting a fly: yeah we could kill them in one hit, but that means you do have to hit them. I think a WAAAY more terrifying dinasour for us would be velociraptor, since they're in our weight class and probably have a manouvrability which would be closer to that of us. and still be able to shred us to bids in mere seconds.

[@Mr.Popo1077]

THANK YOU

[@jerdasaurusrex557]

T. rex could run as fast as an Olympic sprinter. And could maintain that speed over great distances. It's very likely that they also hunted juveniles as most predators living or extinct tend to avoid predating on any individual that can conceivably hurt them back. Injury to a predator is a death sentence.

[@argr4sh]

true, but I do think we're talking about quadripedal juveniles which are still A LOT less manouvrable than humans are. especially in terms of rotating and sidewards movement, which is the type of movement you'd need to not get eaten. (think as in a bull fight).

4:34 actually, the writter scrapped the idea out of the book before publishing it, but he had already talked with Spilberg, and they were writing the book and filming at the same time, and it was much harder to change those scenes from the movie than from the book. In the second book there is actually a guy that dies because he stays still in front of T-rex's nest, the protagonist looking from the security cameras say "he must have read an old paper that claimed T-rex had bad eye sight. It's being long disproven though.", and the T-rex cub jumps out of the nest and eat the guy.

believe it got released few months prios, but it was still under writing as it was recorded, given the writter talked with Spilberg (his friend) when it was still just an idea. Basically he asked Spilberg what he thought about it, if he should write or if no one would like to see it. Spilberg said that whichever he chose, he would make a movie about it, so the writer started developing the story while talking to Spilberg about what he had already made, both for feedback and to inform on how the movie should go. By the way, the personalities of Hammond and the Lawyear are exchanged in the movies, as well as the girl and the boy who I never remember the names.

One well placed swipe from that tail and if it hits the leg of tyrannosaurus, ankylosaurus could literally send trex falling to its own demise from his own weight. Not to mention, ankylosaurus armor could indeed repel at least two bites before succumbing. Triceratops is the most deadly of tyrannos prey but ankylosaurus is the hardest, pun intended, of them all.

[@giggityguy]

It seems strange to say it, but in many ways, I feel like the T. Rex's enormous size is its biggest weakness. When dealing with enormous creatures, it's important to remember the Square-Cube Law, en.wikipedia.org/wiki/Square-cube_law which in essence says that as an object grows larger, its volume will grow faster than its surface area, because surface area grows in a second power exponential relationship but volume grows in a third power exponent. So for ever two units of length you gain, surface area increases by 4 but volume increases by 8. This means that creatures get bigger and bigger, their bodies have to become proportionally stronger and have comparatively bigger bones and muscles compared to their bodies. Kyle has pointed this out previously in the episode about upper limits on the size of titans in Attack on Titan kzbin.info/www/bejne/eJbaomaojauffqc This is why enormous animals like elephants and sauropods have such thick bones proportional to their bodies, especially in their legs. This is an example of allometric scaling en.wikipedia.org/wiki/Allometry , where larger animals have to have stouter proportions to increase the cross sectional area of their bones and muscles, compared to the relatively spindly bones that small animals can get away with. The tyrannosaurus seems to exist right on the edge of what is biomechanically feasible. Its head is positively enormous, and it had to have its incredibly long tail just to counterbalance it. It's essentially just a giant mouth on legs. This means that a lot of its mass is located away from its center of gravity. Not only that, we can assume from its anatomy and estimated native range that it mainly hunted by chasing down prey on flat plains, so it wouldn't have had to maneuver very quickly. All this is to just agree with Kyle's point, that the T. Rex's huge body makes it VERY difficult for it to turn quickly, so trying to escape in an area with lots of obstacles is a good move. In fact it may be even better than Kyle suggested, because I believe that the T. Rex's enormous size would mean that it would have to be incredibly careful in close quarters like this, since perhaps its biggest threat would be itself. Attempting to turn sharply at speed would be a serious danger to its weakest point--its ankles--and colliding with a solid object could be devastating, since some of Tyrannosaurus' bones were hollow to reduce mass, and we're not sure if they had a sternum, so a collision could break several ribs. So the densely wooded part of the island where we first encounter the T. Rex might be the worst place for it to try to catch someone, and I think it would want to be careful about pulling some of the maneuvers it tries at 0:51. It's just too heavy to be careless about throwing its weight around.

[@althedude7730]

Except for the fact that it was mostly an ambush predator and lived in grasslands with forests similar to the one mentioned.

[@giggityguy]

I'm by no means an expert, but I don't look at that body style and think ambush predator. It's too tall, too heavy, and not compact enough. I'm sure that it would attack suddenly and is much better suited to short chases, which I suppose you could call an ambush, but I still get the sense that it had to run, and basic physics suggests that it is much better at running in a straight line. But regardless, it doesn't really change my point. From everything we can guess based on its fossils, it just seems that its body is too big to maneuver in tight spaces.

[@althedude7730]

giggityguy Ambush doesn’t mean fast in the case I presented. It means to wait in a place dense or not and suddenly attack/start walking after a target. It could definitely not fit in very tight spaces but since part of its environment are forests I think he could be able to maneuver through them. (Especially the one presented in the video)

[@althedude7730]

giggityguy they suggest it was an ambush predator that chased out its prey. The chased out part I can explain in detail but the ambush part is basically guess work, we know it hunted and didn’t scavenge much, we know it couldn’t sprint but we don’t know it’s patterning or how still it could stay. I mean elephants are known to be aggressive and suddenly sprint out of the woods without people knowing they even were there so it can be done.

Going for the Achilles would be very risky to attempt, and even if successful, difficult to survive - both for the same reason: that TAIL! Surprised you didn't highlight it's tail - a key weapon in the arsenal of all massive-tailed beasties.
