  • all his evidence shows that it scavenged but it doesnt mena they scavenged for survival. there are also many more evidenc that it hunted

  • 18 feet high up to the head

  • I hate the fact that Horner says that t Rex was a scavenger how would t Rex find a carcus every day it would take days so then t Rex would end up dying after some days

  • Just Beatiful

  • 45 feet Tyrannosaurus is just as long as Giganotasaurus....this brings in new theories :D

  • The problem with these animations is that there's far too much movement. Real animals move with economy, not with all this constant twitching and bobbing and writhing.

    The tyrannosaur roar cliché is one of the most annoying clunkers. While they had the parts to vocalise, we don't have the first clue what they did. For all we know, they may have hissed, yodelled, or did Elvis Presley impersonations.

  • Wait, IT'S THE SAME NARRATOR AS ANIMAL ARMAGEDDON!!!!! No matter how stupid this documentary is, just because of the narrator, I LOVE THIS!!!!!!!!!!!!!!!!!!!!!!!!!!­!!!!!!!!!!

  • I think the holotype of the nanotyrannus is not a baby t-rex, but a baby nanotyrannus!!!! And the adult nanotyrannus is undetected. Or the Tyrannosaurus X is not a male t-rex, but an adult male nanotyrannus. So, no the baby nano is the t-rex hunter(like on jurassic fight club), but the adult nano (maybe an undetected or a tyrannosaurus x) is the REAL T-REX HUNTER.Who knows what's in the face of the earth?

  • horner u faget 

  • why do almost all animations on informational dinosaur shows suck?

  • @ragdoll433 Watch walking with dinosaurs.

  • T-rex question of sorts.

    my 3 year old has a dino toy. it looks like a t-rex of sorts but it has 2 finns on the top of its head. i figure the color of it doesnt matter (i honestly dont know) but its orange with a black stripe going from the tip of its nose all the way to the end of its tail.

    anyone kno what dino this is?

  • @brokenwing36566754

    Sounds like Dilophosaurus

  • 5:30 jiggle jiggle

  • Thumps up if you believe jack horner in that theory, but not t-rex as a scavenger

  • I 100% agree that T.rex change physically as they grow... so.. Nanotyrannus DOES NOT EXIST AT ALL!!!! soo SCREW JURASSIC FIGHT CLUB! has it hint that juevinle t.rexes kill each other like how older bald eagle chicks kill their younger siblings for more access to food from their parents

  • @JJLoW12 Google Montana Fighting Dinosaurs. Sorry to spoil all your hopes and dreams.

  • i agree with jack horner that a juvenile rex may be a better hunter than an large and old adult but t-rex was a hunter anyway. It is proven

  • @kiarash608 Juvenile trexs were better at hunting faster prey. However adults were better fighters and mostly hunted large hadrosaurs and ceratopsians.

  • @AllosaurusFragilis1

    yes i wanted to say exacly this

    juvenile: cheetah

    adult: lion

    and nonotyrannus was a separate dinosaur

    and the hadrosur fossil with t-rex teeth marcks proves that horner is rong.

    but i agree with him that a jub was faster and built for hunt fast prey

  • t-rex ISN'T a scavenge, BIT OF BASTARD!

  • spinosaurs may not be bigger than trex because sinosaurus size is estamated and trex is infact bigger than gigonotosaurs

  • godzilla t rex, like the sound of that

  • very interesting. Thank you for sharing. Jacks mom and dad must have had a good sense of humor. Little Jack Horner sat in a corner. I couldn't pass that up. Sorry. LOL

  • Clearly to me, tyrannosaurus rex was an opertunistic feeder, meaning it would both hunt when it could, and scavenge when it could. It was huge, meaning it had to eat a great deal, and new evidence is now suggesting that they may have even been slightly warm blooded, which would mean that they would need to eat even MORE. So, it likely did both ike many meat eating animals today. AND I WILL NEVER GIVE UP ON NANOTYRANNUS!!!

  • Needed: Ultimate synonym for meat-eating dinosaur. Consult Thesaurus Rex.

  • Tyrannosaurus was a hunter.

    Nanotyrannus was a separate species. It's been proved.

    Jack Horner is an idiot.

    End of story.

  • I can't help but wonder, if you put Horner in a football field with a T-Rex, would he run, or would he have enough faith in his misguided theory to stand there and see whether T-Rex was a scavenger or not?

  • Comment removed

  • jackass hornshit can suck my nuts why would t-rex need a more advanced brain than other predators he is the smartest carnivorous dinosaur which grew that size and he had binocular vision a scavenger wont need such good eyesight which means t-rex is a predator!

  • at 2:09 the guy says that this skull shows many simulaters to trex leading him to belive that is is a youngster.....WELL NO DUR!!!! it shares furtures with trex it is a speices of trex.. Daspletosaurus shares features with trex does that mean it is trex NO!!!!!!!!

  • @winniethethrough yea dude jack ass horner sucks! And should stick to hadrosaurs and not saying crap on stuff he does not know!

  • I had a talk with nate murphy th guy who discovered lenadro, Giganotosaurus and the massive sourpod egg site about this and he said that there is no speices of animal alive today that loses teeth when growing up and end up with less teeth as a adult than it had as a juvinile.

  • i don't think Nanotyrannus was a juvenile t rex, but was its own species, also i think they did not lose teeth while they aged since they replace the old ones. Just my opinion but thumbs up if you agree.

    P.S: I also think T-rex was a predator like a(n) Hyena.

  • @FrshJurassicPrnceYA it is possible that as tyrannosaurs matured and their skulls fused and morphed, some tooth sockets got pinched and closed, or posibly some small rear teeth had a limited number of replacements and were simply healed over once they ran out

  • jack horner is such an idiot,t-rex was a freaking predator! why would a scavenger have teeth the size of bananas with jaws that could bite a truck in 2?he needs to use common sense and stop being such a dumbass

  • @tyrannosaurking whoa whoa come down Horner is just theorizing, I might not agree either, but he's just being a scientist calm down...

  • horners smoking somthing T REX HAS BONE BREAKING TEETH FOR KILLING DUH NOT FOR SKINNING DEAD THINGS fucking retard also i noticed hes getting very old

  • horners smoking somthing T REX HAS BONE BREAKING TEETH FOR KILLING DUH NOT FOR SKINNING DEAD THINGS fucking retard

  • @tyrannosaurking trex did have bone crushing teeth but that could still work if he were a scavenge or not and trex most likely did both and if it could get so big than it would not have to hunt for it's self and could just take other prey and when it was a bit younger it most likely was an ambush predator. no one really knows 100% so we are most likely both right 50%-50%

  • @tyrannosaurking maybe trex had the most ferocious head but the head had bone crushing teeth so if it were a scavenge it would work any way really so matbe hunter or scavenge

  • That Rex roar sounded like a demented penguin

  • Every hunter is also a part-time scavenger. And most scavengers do hunt from time to time.

    That said, for T. rex to wait for animals to drop dead is just ridiculous. Your chances of survival are much higher if you actually USE those colossal teeth and jaws to kill something! Scavenging only makes sense for such a big meat eater if there's no live prey nearby AND you come across a fresh carcass, whichever happens first. You're more likely to find live prey than dead ones, so T. rex hunted.

  • @Glyvenator

    Indeed it would have scavenged raptor kills if it came across fresh ones. But there are two problems which prevent this from being the main source of T. rex's sustenance. First, the only raptors in T. rex's habitat were tiny ones like Dromaeosaurus - too small to bring down the kind of prey T. rex needed, even hunting in packs. Second, they are very RARE in the fossil record. Far rarer than T. rex. So even coming across a raptor kill wasn't likely on most days. T. rex had to hunt.

  • wtf is wrong with ppl not all t rex were 13 ft tall some were a bit taller

  • This was uploaded on my birthday

  • One problem wiv the Nano/T-rex deb8 is that they only base it on 1 piece of evidence...the tooth number. but there R other factors which R Xtremely different from T-rex. The shape of the brain, where it was positioned but most of all the fact that it's a fused skull, and only adult animals have fused skulls. That's enough 2 tell me that Nanotyrannus is it's own species & not a baby T-rex.

  • Scavenger only? Then explain the binocular vision, super hearing, super strong jaws, and the extremely re-enforced hind legs to reach high speeds of the T-Rex!

  • HORNER IS A RETARD

  • I dont see why it could not be both a hunter and a scavenger. Survival means you need to take every oppurtunity availble to you.

  • I agree with the aging thing. It just seems stupid that SO many different kind of dinosaurs lived. It makes more sense if there were fewer that just grew up.

  • @tyrannosaurking totaly its mouth was desighned to crush bone id like to c horner stand in front of a trex and c if it was just a scavenger =P

  • Dinosaurs decoded aka the Horner show: Now 100% fact free!

  • Nanotyrannus was definitely its own species of tyrannosaurid.

  • Nanotyrannus a newly discovered tyrannosaurid.... debated among scientists whether its own species or a juvenile version of the original T-Rex

  • The small blade like teeth are needed for earlier life, youngsters cant crush through solid bone or tough hide for that matter. As it grew, its mussle would get stronger and it would start hunting. It would soon replace the "baby" teeth for the deadly spikes we know and love. And i, a 14 yr old kid just destroyed jackASS's theory! Haha!

  • Horner style nanotyrannus = baby t-rex

  • @htfamily

    who is nanotyrannus

  • why rex is so big here but the skull is not like that

  • Bloody hell, T. Rex's arms weren't THAT small. Its not an Abeiliosaurid for god's sake.

  • K!!!!! last comment... reduce species to a third?! but what about one who looks like one but is from another age?! like jurassic!? or Triassic?!

  • @tyrannosaurking a.... sorry for spamming but im also bussy so i cant type more then 19 words in a comment, But anyway, Dont turn against horner, were still some "dinofags" as some people call us, and were still young new generations, we cannot know about that, since everything... is possible...

  • @tyrannosaurking But remember bud... T-rex doesnt risk always... we dont either.. birds doesnt, reptiles doesnt, then maybe rex wont take so much risk.. even more if it has a youngster...

  • OHOH for the folks watching Dino books... look out that it isnt from 2007 or less lol.... or close... those are lies.. we get news all the time...

  • whenever i hear t-rex was a scavenger,i click away from the video

  • WTF are they on about? Nano Tyrannous is a SEPERATE SPECIES not a baby T-REX!!!

  • @attractivue its the ancestor of t-rex evolved to be big i think

  • @attractivue yeah but still a baby rex or a teen may look different from the adult don't you think. more light build, to be faster, and more

  • @attractivue also may be nano t may still be its own species. it is possible that nano t-that we have may still be a teen and not a full gourd adult. who knows.

  • Horner forget the many arguments:

    - Hadrosaurid and ceratopsians are also likely to be heavy and slower than T.rex.

    - No need for long arms, if t.rex has giant teeth

    - Binocular vision much better than human

    - There is no evidence for the existence of another large carnivore

    So Tyrannosaurus was a apex predator

  • @7Alx94 I HEARD THAT JACK HORNER THOUGHT RAPTORS WOULD HAVE BN THE APEX PREDATOR. NOW I'M NOT SAYIN RAPTORS COULDN'T HUNT BIG DINOSAURS, I'M SURE THEY COULD, BUT THE RAPTORS RN'T GONNA CONSTANTLY HUNT & T-REX CONSTANTLY SCAVENGE, THAT SOUNDS SILLY. BOTH THESE CARNIVORES WOULD HAVE HUNTED IN DIFFERENT WAYS BUT I AGREE WIV U, T-REX WOULD'VE BN THE TOP PREDATOR OF IT'S TIME.

  • @7Alx94 he also said t-rex can crush bone for eating more of the body but many animals use a bone crushing bite to kill animals and would work a bone crushing bite would kill prey a lot faster than with arms

  • T-REX YOUNGSTERS DID LOOK MORE SLENDER THAN THIER PARENTS BUT TESTS ON THE SKULL & BRAIN OF NANOTYRANNUS CONFIRM THAT NANOTYRANNUS IS IT'S OWN SPECIES & PERSONALLY I THINK T-REX WAS MORE OF A PREDATOR THAN A SCAVENGER BECAUSE IT'S JUST TOO ADVANCED TO SURVIVE JUST ON CARCASSES.

  • So Nanotyrannus is a false species and the T-rex wasn't a scavenger. I believe it was both a Predator and a Scavenger.

  • I don't belive that T-rex babies looked different from there parents you don't see that today in the Modern World. And belive Nanotyrannus is it's own species.

  • @tyrannosaurking Yeah! I agree!

  • @tyrannosaurking Jack Horner knows nothing about T-rex or Spinosaurus.

  • awsome clip though the rex does look alot like albertosaurus

  • looks a little bit more like albertasaurus.

  • I don't get why they say it must be a scavenger because it had bulky bone crushing teeth like a hyena, but hyenas hunt a lot. I'm sure Tyrannosaurus scavenged, but I doubt it was a scavenger.

  • @sorryimsogreat2 JackASS Horndog's LAME "T-rex a scavenger only" theory had long been debunked by top paleontologists; most notably Bob Bakker, Pete Larson, Phil Currie & Ken Carpenter, whose Hadrosaur specimen (Horny's favorite species) provided a strong evidence of T-rex hunting (healed bone in the Hadrosaur's tail). This made JackASS a laughing stock to his colleagues; for the simple reason that he forgot something very simplistic: scavengers don't wait for an animal to drop dead! THEY KILL!

  • @MlKETYSON I know were scavengers and huntures

  • veeeeeeeeeeeeeeeeeeeeeeeeeeeer­y cool 5\5 +fav

  • This T-Rex model more look like Albertosaurus

  • cool.

  • jesus...we are learning more and more...soon enough people will go cloning them like in jurassic park thinking we can control them?we do not stand a chance against dinosaurs!amazing video 5 stars!

  • @jpog1289 th... um i have posted alot now here but anyway.... Our technology will maybe get even better too when we maybe clone them... who knows? i like cake....

  • @PBdarkraptor I saw this video over 4 months ago and forgot the comment,sorry i have no fucking clue what your talkjing bout

  • hell, even the animals that lives today looks diffrent when thier younger and do go throw changes as they grow older

  • "knarly noses'" :-)

  • I really wish they would have Dinosaur shows on TV again. I don;t care, even if they are repeats. There havn't been any on in so long, I wouldn't remmeber them (nor would I remmber them because I just recently got back into dinosaurs). I wish I could go study a skeleton of a dinosaur for my own study purposes. I think there really are too many species than there should be.

  • I didn't have room before but, I saw in Discovery Channels 2010-11 channel lineup, there will be a dinosaur show on they are making with Disney and Pixar

  • I didn't know that Nanotyrannus was a teenage T-rex.

  • I believe Nanotyrannus is its own species. My mind could change sometime in the future, but for now, I see enough diffrences to keep them separate.

  • What a unique color rendition for T-rex...i like it!
