Could you outrun a T-Rex? @ 2013/04/07 07:46:38


Post by: Ouze


Probably not (source). In my effort to post less political stuff in the O-tizzle, here is some important research.


Could you outrun a Tyrannosaurus rex?
Just how quick was the great tyrant lizard, exactly? Experts in biomechanics think she was pretty damn quick – but still probably not as fast as you think.



Researchers have been debating over the speed of dinosaurs – and T. rex, specifically – for years. Reconstructions of dinosaurs toward the end of the 19th century often depicted them as fast-moving creatures, but by the mid-twentieth century, that vision had been turned on its head. Large, bipedal theropods like T. rex were often presented standing completely upright, their tails dragging along behind them in a manner suggestive of slow, lumbering locomotion.

Over the last few decades, however, the standard model of T. rex locomotion has been revised yet again. Some studies have pushed for a "fast-running" T. rex hypothesis, claiming that the tyrant lizard may have been capable of speeds in excess of 45 miles per hour – but more recent investigations now suggest that T. rex was neither sloth-like nor super-swift. According to John R. Hutchinson (who has published studies on T. rex biomechanics in scientific journals no less-esteemed than Nature), Tyrannosaur speeds likely topped out in the "moderate range" of 5–11 meters per second, or between 15 and 25 miles per hour. You might be able to outrun a T. rex on the low end of that spectrum – but the middle- to high-end? Unless you're an elite athlete, odds are you're a goner. (For reference: Usain Bolt holds the world record for fastest human footspeed, clocking in at just under 28 miles per hour.)

What about other Theropods?

One of the most significant studies to examine the speed of T. rex and other theropods was published in 2007 by William Sellers and Phillip Manning, paleontologists at the University of Manchester. The study was unique in that it relied on a computer program called GaitSym to model the top speed of five different dinosaurs: Compsognathus, Velociraptor, Dilophosaurus, Allosaurus and T. rex. (All of which, it bears mentioning, were bipedal and carnivorous.)

The pair used data from known fossil models to reconstruct the dinosaurs' locomotive anatomies and musculoskeletal features. These models were then pushed to their limits in the GaitSym program, which ran each dinosaur's model through different combinations of muscle activation patterns. Patterns that caused the models to falter were abandoned, while simulations where the dinosaur ran at least 15 meters were investigated more thoroughly.

Finally, Sellers and Manning simulated the running speeds of humans, emu and ostrich – species with documented top speeds – to help validate the accuracy of GaitSym. Here are the figures they came up with, as reported in Proceedings of the Royal Society B:

Spoiler:


This is the table we used to create the infographic up top. You'll notice the estimated speed for T. rex (8.0 meters per second) is smack dab in the middle of the "moderate range" of 5–11 ms-1 cited by Hutchinson. Dromaius, Struthio and Homo correspond to emu, ostrich and human, respectively. These numbers corresponded well with top speed data for all three species, and helped demonstrate the accuracy of the GaitSym model.

The upshot: the smaller the bipedal theropod, the faster it runs (just look at that freaking Compy!). The good news is that according to Sellers and Manning's models, the monstrous T. rex would actually be the easiest of the simulated dinosaurs to outpace in a sprint for your life. The bad news? Considering the average T. rex clocked in at about .44 kilometers per hour faster than the average human, there's still a pretty good chance you're humped.

I suppose the only consolation hidden in these findings is that when Sellers and Manning performed these simulations in 2007, they were still using model predictions that put T. rex's weight at 6,000 kg, but a study published by Hutchinson in 2011 put this figure at over 8,000 kg. If we go by the rule of bigger = slower, there's a chance the newer, larger T. Rex model would lag just a bit behind your average human. Unless T. rex really did run closer to 11 meters per second, in which case you're probably doomed no matter what.

    I read a thing a couple of years ago that said T Rex may not have run very much because if it fell over it would break its neck owing to its front limbs being so small.

    Instead, it was an ambush hunter. (Which poses the question of what it hid behind.)

    Because all our government leaders are reptilians and the only reason humans exist is because the reptilians wiped out the dinosaurs and are keeping the DNA of every dinosaur species in a secret lab just in case they need to reintroduce the dinosaurs back on this earth

    because if the humans find out there leaders are secretly 5- to 12-foot (1.5–3.7 m) tall, blood-drinking, shape-shifting reptilian humanoids from the Alpha Draconis star system, that use human disguises. That's why.

    I wouldn't have to outrun a Trex, I'd just remain perfectly still. As long as I remain still and aren't seated on a toilet, I'm good to go.

    I learned this from a Steven Spielberg amusement park documentary when I was little. Steven doesn't lie.

    I personally would think that, if it were an ambush predator, that this would mean it plays off the notion that dinosaurs were incapable of distinguishing shapes, etc. but instead relied on movement and vibrations (similar to snakes today?) in order to see their own doom.

    I would have thought the T-Rex would go for "aggressive scavenging" - essentially let other dinos do the hunting, then muscle in and steal the kill. Sure I read that someplace.

    But anyway, Hiding would be better than running, I'd say.

    Zombie T-Rex is another matter!

    What to do if you find yourself being chased by a T-Rex with no hope of outrunning or escaping it:

    Consider yourself lucky that life has been good to you so far. Alternatively, if life hasn't been good to you so far — which, given your present circumstances, seems more likely — consider yourself lucky that it won't be troubling you much longer.

    If it was an Ambush predator it was probably capable of short fast bursts of speed but would quickly tire out.

    And it wouldn't be all that hard for it to hide. a stand of trees would be sufficient. Its not like it only lived on open savanna where everything could see it coming from miles away.


    Humans would have several advantages over the T-rex.

    1) a little too small to be worth the effort.

    2) can hide in places the T-rex couldn't reach.

    The Lion is perfectly capable of killing a Mongoose, but its too small to be a worthwhile food source.


    Humans would need to worry about things like Raptors. Allosaurus maybe would prey on humans but it would be a rarity.

    Actually it depends entirely on how fast the polka-guy on it's back is playing the bass drum.

    I think a Human would generally be okay against a T-Rex, because when running from a much larger, heavier adversary, the smaller, more lithe prey has the advantage of being more able to make rapid, 90-degree turns that the much larger T-Rex cannot match or compensate for. Those top speeds assume running in a straight line, which -unless you are Usain Bolt- is a bad idea.

    Bolt could almost outrun the raptor over 200m. He'd be neck and neck with the dilophosaurus...probably not where you want to be when trying to run away from it.

    You'd probably need to get a shotgun, AR-15, or .45 caliber something before you starting being dangerous to it. And then you may not kill it right away.

    I think if you lived exclusively in heavily wooded areas you could outrun it by virtue of being able to maneuver better around tree's.

    Or you could challange it to see who could do the most pushups in a minute.

    Why would you be running? TRexes are vegetarians. They have the peg teeth to eat coconuts. Thats why early Frenchmen hunted them to extinction. Poor TRex, killed by the French.

    Wouldn't be my approach anyway. Let's face if you're in a dinosaur wilderness, you've got play to your strengths.

    Personally I'd go with the "Is mammal, digs hole", method of survival. T-Rex ain't fitting in my burrow, and with legs & arms like that he certainly ain't diggin' me out.

  • Thanks for this - I found it good reading

    Most of us still couldn't outrun it though - Warhammer not normally being a good sprint speed determiner. Although if we taught it to read and then how to play, we could probably baffle it with RAW vs RAI arguments.
    I do like the idea of a Trex being an ambush predator - like Rambo. Sneaking up behind people, getting them in headlocks with its tiny arms and snapping necks. While rocking camo face paint.


    IIRC - Triceratops is now being looked at as a potential juvenile Torosaurus (larger version of triceratops)
    I also watched some tv program where they proved that if the triceratops charged at something at full pelt, it'd break it's own face. So they now think the spikes were purely defensive.
    Brontosaurus used to be my favourite, then I found out it was made from an incorrect build - it had the wrong head, thus my favourite dinobot is now invalid.

    Did anyone read the book jurassic park 2? there was a part in there about T rex's vision not being based on movement, as that would be dumb (prey animals natural response being to freeze before running. They also said anything larger than a goat would fill it for ages and thats why it didn't just eat them all in the first film)
    Sure beats the film...where a trex can get out of a cargo hold, eat everyone while doing no damage to the ship then lock itself back in. In the meantime, the only people who can find the trex on the mainland are the heroes.
    It knocks down a wall, roars, eats a dog and the kid goes to warn his parents - who havent woken up yet?
    The velociraptors shrunk (they were oversized in the first film to make them better on screen villains - then a short while after they'd made it up, they found the utahraptor, which was an oversized variant)

    In the first book/film, the kids roles were reversed too - The boy was the older computer geek and the girl was about 6. Random...

    The coolest dinosaur - I like Baryonyx. No idea why.

    Velociraptor - dressed in feathers doesn't seem as bad. Without feathers - It'd be like being chased by a naked lizard/chicken.

    Thinks thats as on topic as I could get

    That's a lot of muscle and very little brain for a bullet, unless it's a very big bullet.

    You'd be better off going for a torso shot. I'm not sure what the resistance of a skull that thick to a bullet would be, but if Bison skulls are practically bullet proof then I'm betting the T-rex is probably in the same vicinity.

    Sharks, killer whales, and possibly polar bears? I know that polar bears do ambush their prey, but not always, right?

    What is the difference between an ambush predator and a 'regular' predator?

    I would think that all predators rely on at least some element of surprise. Does it depend on just how sneaky and/or how long they chase?

    You already know the difference, if you think about it. While all predators do depend on the element of surprise, consider the difference between a lion attack (where it actively, and stealthily, tracks down it's prey) and, say, a crocodile, which will pick a nice spot, wait motionless for as long as it takes for some creature to come up and take a drink, and then attack it.

    I imagine for a creature as large as a T-Rex, being an active predator is impossible - just soo much energy cost for risky, possible unsuccessful hunting. I wonder if they even stayed submerged frequently.

    An Ambush predator is one that lays in wait until its prey comes very close, close enough for it to grab it before it escapes.

    Other predators chase their prey down, usually after stalking as close as they can get.


    T-rex probably did some chasing down, but more closer to a Croc than a Lion. Close enough as hundred ton animals can get anyway.

    Allosaurus was probably more akin to a lion as a predator that tracked down and stalked its prey. Possibly in packs.

    T-rex may have also followed other large predators, that were still smaller than it, around and stole their kills. Or eaten mostly carrion. Or a combination of all three.

    Is there any thought they may have been semi-aquatic?

    TBH I don't see outrunning a T-Rex as being all that difficult. All you have to do is go round a corner and suddenly you're ahead, as they'd just have far too much momentum.

    And a velociraptor with feathers would look like a large, clawed chicken. Which wild chickens can sometimes look rather majestic, the old model of a scaley velociraptor would probably look more terrifying.

    There's research being done into dinosaur lungs. It's been theorised that if they had lungs like birds, they would be far more efficient with energy compared to us.

    This is right IIRC

    From wikipedia
    As the foramina on the outside all communicated with a space on the inside of the snout, the authors speculated that Spinosaurus had pressure receptors inside the space that allowed it to hold its snout at the surface of the water to detect swimming prey species without seeing them.

    A 2010 isotope analysis by Romain Amiot and colleagues found that oxygen isotope ratios of spinosaurid teeth, including teeth of Spinosaurus, indicate semiaquatic lifestyles.[41] Isotope ratios from tooth enamel and from other parts of Spinosaurus (found in Morocco and Tunisia) and of other predators from the same area such as Carcharodontosaurus were compared with isotopic compositions from contemporaneous theropods, turtles, and crocodilians.[41] The study found that Spinosaurus teeth from five of six sampled localities had oxygen isotope ratios closer to those of turtles and crocodilians when compared with other theropod teeth from the same localities.[41] The authors postulated that Spinosaurus switched between terrestrial and aquatic habitats to compete for food with large crocodilians and other large theropods

    Yeah, those ostriches are scary, really...

    On a more serious note, I'd be surprised if dinosaurs (at least the late ones) didn't have lungs like those of a bird. After all, they evolved into birds.

    Heck, we know for certain that the latest dinosaurs have lungs like birds, given that they are birds. See that pidgeon out your window? Dinosaur. That magpie? Dinosaur. That blackbird? You guessed it, they're all Alpharius. But also dinosaurs.

    They can kill a lion in one kick just from blunt force, let alone any disembowlement caused by the claw. People have been literally disemboweled by ostrich before.

    Eldar Exodites use dinosaurs...if they ever appear. Been waiting since 2nd ed. Some people have done custom flesh tearers - what with the home planet being 'cretacia' and having big 'not dinosaurs' roaming round on it.

    They were Utahraptors, conveniently discovered just in time for the movie. (The book had velocirprators, considerably smaller). Whats scary is look at the biggie sized Utahraptor. Thats Allasauris sized. YIKES!

    DNA has too short a half-life to survive that long, unfortunately. It's possible we could reverse-engineer them from fossils and living birds, but it'd only be our best guess at what they were like.

    Frazz, that was pretty much my point. They are consistently referred to as 'Velociraptors', even though Velociraptors are only knee-high. Even Deinonychus is only hip-high (although definitely capable of killing a person). Utahraptor is too big, even the smaller one shown, to be the critter in the movie.

    I'll grant you that there HAD to be a transitional form between Deinonychus and Utahraptor that would be that size... but we haven't found that one as yet.

    A transition form might easily only have lasted a few dozen generations, so therefore practically not exist.

    Ayah Deinonychus sounds like a gladiator or a Greek hoplite. They needed less greeky more scary.

    It's basically a choice between an unevolved bird and slaanesh. A difficult choice indeed.

    Speaking of dinosaurs failing..

    Spinosaurus would die if he fell over. His "sail" was connected to the spine, essentialy breaking his spine if it tripped badly.

    It might not even have been a sail - they've assumed it was. It could also have been a hump

    wikipedia wrote:
    The distinctive spines of Spinosaurus, which were long extensions of the vertebrae, grew to at least 1.65 meters (5.4 ft) long and were likely to have had skin connecting them, forming a sail-like structure, although some authors have suggested that the spines were covered in fat and formed a hump.


    I always thought that a strong wind would screw him over if it was a sail. He'd have to run by tacking into the wind

    Besides, we all know Ankilosaur is the best dinosaur. It's an armor plated battering ram with flail for a tail.

    I agree - It's definately better than triceratops - a study showed if triceratops charged something like a t-rex, he'd break his own face.

    Ank was a sturdy dino

    Couldn't have been that big a deal. If it was that big a deal we probably wouldn't see much evidence of their existance.

    As opposed to the completele overflow of spinosaurus fossils, right?
