  • feathers...feathers..feathers.­..

  • This episode had one major flaw - Deinonychus lived 110 million years ago, long before Trex, it would have probably encounters Acrocanthosaurus, not Trex

  • Arrow in the knee ???

  • Dromaeosaurus wasn't even a contemporary of Tyrannosaurus wtf

  • 6:28 Predator becomes prey.

  • 5:13-5:20 NO!!!!!!!! NOT JIMMY WHY!?!?!?!

  • why doesnt it jus run instead of standing there an letting them attack 

  • raptors communicated with quick hand gestures so raptors were the early gangsters

  • @diegoisimo plus they attack in groups

  • Me almost at the ending of vid: wait what about the t-rex? o.o

  • More evidence: the wrists and arm bones of raptors were articular enough to make simple gesture. The optic nerves and visual centers of the brain were highly developed, much like a bird, had the ability to process and interpret information of color, movement, and other cues that could be used in hand gestures. Where did info come from, I present to you, the fossilized remains and advanced medical scanning equipment. And I suggest using a constructive argument with fucking EVIDENCE AND FACTS!

  • @MrHudDakNic12271990 Oh, finally! I've been waiting for someone to make a claim using evidence and supporting data! I am not being sarcastic; people always hate on me when I do what you did. Then again, it's always the angry people that reply to my comments, haha. One guy called me a moron and blocked me from his video because I refuted his claim with facts I learned from by college's biology book. I just wanted to thank you for being one of the few people to use their brain when making claims!

  • @MelyssaAKASkittlez No problem. I've been working in this field for a long time, and plus I know that in science you have to back your stuff up with evidence rather than opinion. I usually don't use curse words when making claims, but I was trying to make my point across to the guy who wasn't using his brain. So the guy who blocked you is the moron, not you. You did what scientists of all kinds do all the time.

  • @MrHudDakNic12271990 Even though it should be normal, I still congratulate you since its such a rare quality on youtube. The video was called "Greatest Misconception 1: Birds evolved from Dinosaurs." I did not outright say the dude was wrong, but his understanding of some definitions was far off. He resorted to such harsh treatment to other users, too. He even thought my friends was me and blocked them! You may want to check out the video just to see for yourself his claim.

  • @MelyssaAKASkittlez I see what you mean. I'll look into it and see what I can do to help clear things up about his claim. I think that there be some misunderstanding on his part, but I'll try not to use harsh methods unless forced too.

  • @MrHudDakNic12271990 Mostly what he was saying was dinosaurs and birds share a very close relationship to the point that in the fossil record it is hard to tell the difference between early birds and ancestral dinosaurs. But it seems that others have been giving him a hard time and thus he resorted to harshness.

  • @MrHudDakNic12271990 Thanks. I tried being nice to him! I just feel bad for the people that view the video and believe the entirety and end up learning incorrect information. In his video description he says if he made a mistake to let him know but that failed. >,<

  • And further evidence shows us, their living descendants, birds also use their wings in communication. Also using gestures as opposed to loud mouthing, something you're quite familiar with would ruin a stealthy pack attack. As for my piece of overglorified shit, I make six figures a year working in a job I love. Where does that leave you? You see I can keep going on with my evidence, but what about you, oh wait I see nothing supporting you. I guess you're the scholar who said the world was flat.

  • Comment removed

  • Thanks to CT scans of the dromaeosaur's skull we can see the brain cavity.By taking a highly detailed endocast we can see how well developed the areas of the brain responsible for hand-to-eye coordination and communication. These are very bird like not to mention that these dinosaurs were feathered meaning the feathers are their arms would have some type of visual display.

  • What a faggot.....this fucking losers have NO IDEA what they did anymore then you or I do. No one witnessed it so it's ALL guess.

    I say they communicate by WIND mobile this is fucking ridiculous guesses

  • @ry27sm There much more than just guess work that goes unto this. I should know, I've done both lab and field work on these dinosaurs, for the most the majority of the evidence comes from the fucking fossils themselves, and if you know how to read the goddam bones, skin impressions, and study modern analogs. So doctors like me, WE DO HAVE A FUCKING IDEA. So before you go off half-cocked, do fucking research, get a PhD in the field, then you can have a fucking say in how ridiculous the video is.

  • @MrHudDakNic12271990 Oooh so the fossils tell you that the Raptors use a form of sign language how?

    Please enlighten us all Dougie Howser M.D.

    Some of the best scholars believed the world was flat yet somehow they know the behaviour of dinosaur in a time they didnt even exist in. Funny they cant understand HUMAN Egyptian past but somehow know the methodology and THOUGHHT process of animals they never observed? LOL GTFO...Guess your so called PhD is just a overglorified piece of shit.

  • 6:29 Good catch

  • @BIEBERBRO420 Take your Bieber Fever somewhere else.

  • lol, if i remember right a dromaeosaurus is a member of a group witch includes all sorts of raptors

    a group witch all have the sicle claw to destinguish them from other dinosaurs

    though the family is called dromaeosaureae or something like that, its not totaly correct what they said at 2:52

  • Ok, question: HOW do scientists "now know" that the raptors communicated by hand gestures?? It's not like they've got a few in a lab somewhere that they can watch!

  • @MrsNorris55 In truth no one knows but in the modern society, people are not allowed to use words such as "maybe", "probably" or any words like that. It's considered *unprofessional* to them. Even in school when writing essays students are not allowed to use any words that give people the impression that they are assuming things even though they actually are assuming. Honestly, I don't agree with this system though since it leads to too many inaccuracies that are difficult to amend.

  • @SmokebuoyII yeah. what happend to free speach? also this is dinosaurs we are talking about. prehistoric creatures that we dont know everyhting about. so of course its gonna be words like mabye and probably etc. with prehistoric creatures it should be allowed. some systems are just really out there.

  • @MrsNorris55 as you do i doubt that the raptors used their hands to communitate...I believe they used different sounds to coordinate their attacts...

  • @MrsNorris55 I think they just watched Jurassic Park ....

  • i clicked the second part before the the first and i thought the raptors were its babies

  • I like this, but no offence to Americans... British dinosaur programs always seem better... :$:$

  • @flapjunk I hate to say this, but your 100% true. XD

  • 360p is not hd

  • @Jopari444 What does it say on the lowest right corner of the video?

  • @SmokebuoyII well i live in finland and it says "koko näyttö" which means full screen. not sure what do you mean. hd is 720p minimum, this is 360p

  • @SmokebuoyII Thanks for the upload! I'm a huge dinosaur fanatic, have been since I was a kid.

  • So, deinonychi had alpha males, but with dromaeosaurus the alphas raptors were female? Does anyone know? i thought deinonychi had alpha males? All the raptors hunted in packs (all species) and all had alphas, but I don't think all were head by females. I am interested in which raptor species had females as opposed to male alphas, and if for some species it changed depending on the pack.

  • how do we people learn about the dinosaurs? they are now fossils we can study them in fossils but no one knows how they kill thumbs up if you agree

  • @ferbthegadgetguy I completely agree.

  • @SmokebuoyII thanks

  • @SmokebuoyII i like ur vids dude they look like the TV an not bad like the recorded ones :)

  • @ferbthegadgetguy but hey it's cool to watch the possibilities so im not complaining

  • @distantworld102 ya i know

  • @ferbthegadgetguy If you study the fossils and compare them to living animals with similar bone structure you can make some assumptions. If you find a bunch of carnivores intermingled with the bodies of herbivores you can be pretty sure they were hunting that herbivore in a pack. Animals that hunt in pack are usually more intelligent and have a social order (someone has to be giving the orders, so you need an alpha of sorts, which means more intelligence than a slow moving herbivore).

  • @lexikalfanfic i didn't understand

  • @ferbthegadgetguy im with u dude :D

  • @ferbthegadgetguy Yeah, who knows, a velociraptor could have done a spinning back kick for all we know. Lol

  • @ferbthegadgetguy they look at modern animal for the answer. its not 100% right however it is pretty accurate

  • @orlin800 so why did i get some thumbs down? i mean thats hard

  • @ferbthegadgetguy i dont understand what you mean. you havent got any thumbs down and what is it thats hard?

  • @orlin800 i cant see my thumbs up and you know how hard to get a thumbs up?

  • @ferbthegadgetguy It's kind of like detective work. Sometimes your lucky enough to find skeletons of animals that died and were remain in a certain position while they were fighting. However, this is only a snapshot of the moment, and I agree that it's going to take a lot more time to understand how these things really did hunt and behaved... but it's still fun to watch them tear and gnaw at each other to death :)

  • @ferbthegadgetguy But while watching the film, they seem to used cats as a resemblance to dinosaurs. They said "like a cat" twice lol.

  • @ferbthegadgetguy It is pretty all hypothetical. What we humans do when we study is look at these dinosaur fossils, compare them to similar species, and kind of see how our modern day species react when in a predator situation, or what a predator does when it hunts, and well make a scientific conclusion that this is what we can assume was how dinosaurs would have been like back in the day.

  • no english me french

  • Raptors wouldn't stand a chance against a T-rex.

  • @Lettich3407 Raptors might stand a chance- the T-Rex was much slower- much heavier and stronger, but much slower (both physically and mentally)- if the raptors could avoid being whipped by the tails and attack as a group and use their scythe like foot claws to rip open the neck and do that long enough, in a big enough pack, they could bring down the T-Rex. It would be an awesome fight to watch though. Deinonychi had bones like crows and could die from being thrown to the ground hard.

  • @lexikalfanfic t.rex was not that slow it ran 30kph sciencedaily site stated so

  • @cf572 Yeah, but look at it's size. The stride of the average Rex was 6 feet between walking steps, so imagine its stride while running. 30 kph for an animal with a running stride of 9-10 feet is a slow pace. Logic fail. Considering their proportions, raptors were much faster. Period. Your comment is like saying that a 7 foot tall man is "faster" than a 2 foot tall child simply because he will cover more ground with each step. See the problem there?

  • @lexikalfanfic i did not say raptors were slower they infact run like 40mph as JFC stated. i only said "t.rex was not that slow" sciencedaily,national geographic did body structure studies on a t.rex's body and ran faster than a human but thats actually beside the point t.rex had thigh muscles extending tail muscles from the thigh to the tail for increased speed logic fail? since when did i say t.rex was faster? tried at 6ft and t.rex grows 40-46 feet long

  • @lexikalfanfic well "that a 7 foot tall man is "faster" than a 2 foot tall child simply because he will cover more ground with each step. " smaller or bigger does not entirely mean "faster" lets take allosaurus and ceratosaurus now allosaurus is nearly twice larger than ceratosaurus though it has way better body build and is faster though it is twice as large. i dont take sizes when it comes to comparing speed i only said "t.rex is not that slow" deinony ran 40mph t.rex 30 kph only

  • @cf572 ah, but also, when I said "faster". I was referring to reflex speed. Because it is larger it might be able to cover more ground in the same amount of time in a straight line, but add in quick swoops and turns and that would slow it down considerably.This is all anecdotal but assume the Rex is chasing dinosaurs in an area that is fairly open but has trees and other obstacles (instead of a wide open plain) which it has to move around. Also, I guess "slow" is a subjective term.

  • @lexikalfanfic oh sorry for the missunderstanding but i thought you were one of those guys judging speed following that lame paleontologist jack horner. and all because its upper thigh bone is longer than the lower leg bone means it ran as slow as an elephant. yes t.rex can't turn quick it takes him like 2 seconds to do a full turn unlike the more agile raptors. it will take at least 10 deinonychus raptors to take a t.rex down or 4 utahraptors

  • @cf572 Yeah, that would be my guess (on raptor numbers). I'd say 3-4 seconds for a full turn for Rex. By speed I was also initially referring to reflex speed/brain speed/ability to quickly dodge around objects, etc. The only way I think we could know for sure how fast the rex ran would be to have a series of imprints of it walking, versus running (like how CSIs study human footprints to determine speed while running based on how deep the imprint is). No need to apologize.

  • @lexikalfanfic all im saying is. is that t.rex is not that slow lots of people think it ran as fast an elephant it actually ran faster just because there both 8 tons. or just because it had a long stride and we should ignore the t.rex body mass tail-torso-thigh-leg structure studies or the fact 6 feet long stride is not that long of a stride for something 40-46 feet long. but all im saying is that t.rex ran 30kph thats fast for something 40 feet long

  • @cf572 Here is the problem... 30kph is not fast at all for something 40 feet long (and it's length doesn't matter as much as it's stride or the distance it can cover with each step). How "long" are humans? Far less than 40-45 feet divided by 10, and a running speed of 3 kph for a human is pitiful. That was my point. Sorry if I sounded short.

  • @lexikalfanfic stride does not entirely mean fast it also matters how fast your moving too t.rex was said to run 18mph thats 29kph while some scientist believe its 40mph which i have to disagree on. the scientist point is how fast t.rex moved with those two large legs your right length does not matter im talking about 29mph is fast for something 8 tons where as to elephants cant run 29mph not even close do they? at first everyone said t.rex ran as fast as an elephant all because of the weights?

  • @cf572 I know stride does not entirely mean fast, that was the point I was making. Also, now you're comparing weight, but elephants have much shorter legs so of course they won't run 29 kph (I know you wrote mph). What are we disagreeing about here? I don't think T-Rex was as slow as many people believed, all I said was that I think raptors, in a pack, might have a chance.

  • @lexikalfanfic "but elephants have much shorter legs so of course they won't run 29 kph" exactly while that horner only looks at "weights" even his pterosaur's catching fish with their feet theory is non sense to me even his scavenger theory he is not a good paleontology. i dont care if he is one of the most "famous" paleontologist dinosaur george should have guided jurassic park. so yeah 10 deinony or at least 5 utahrapts can take out a t.rex well cya

  • @cf572 If he is only looking at weights... well, yeah, see we are agreeing. Also the muscles structure and bone structure of an elephant's leg is much different. Horner is being silly in that respect. You can't assume animals will be the same speed based on weight- even with similar bone structure and muscle structure (and elephants and rexes were not alike anyway) there are too many variables. Weight is just one. Cya. :)

  • @lexikalfanfic as to humans running 15mph we look at our leg design its not designed for running like those legs of a birds or raptors leg. now here is your problem that you need to be concerned of. these leg muscles moved in a fast motion why? again muscles from the thigh connected all the way back to the tail muscle's from the tail supporting the thighs for increased leg motion speed my point was not saying t.rex ran fast because of its stride not mostly actually because of the body structure

  • @cf572 Ah, you have to love facebook. I think we're actually agreeing on the same thing. My initial point was that I believed raptors could possibly take on a Rex (that it is possible, especially a young or injured rex, and if the environment was right, and if there were enough members, etc, etc). Why are you discussing raptors now? I know we don't have leg muscles like either raptors (or birds). Never said we did.

  • @LordTrilobite not all did

  • Because of the movie Jurassic Park, many people at first think that T-Rex lived during the Jurassic Period, but it didn't, it lived in the Cretaceous. The only dinosaur that you see in Jurassic Park that actually LIVED during that era is Brachiosaurus.

  • @antidisastablish333 Dilophosaurus did too

  • Haven't watched part 2 yet. But if these Raptors have trouble with a lonely Edmontosaurus, I doubt they can mess with a t rex. We'll see.....

  • dude please reply to this comment but can you upload the fight at 0:00- 0:23 it was very epic!

  • This is a modern documentary, why do those raptors have almost no feathers here?

  • Edmontasaurus : to all : omg nice ss go stfu team , and u raptor gj for ganking 1v5 noobs . Raptors : why are u writing to all tard we dont care about your opinion , btw is a team game!!!. Edmonasaurus FUUUUUUUUUUUUUUUUUUUU

  • Comment removed

  • hey if the dinosaurs didnt go extinct we would be sentinent raptors

  • This is the first really realistic display of how went when dinos where alive as far as I'm concerned. I personally suspect the sauropods stormed nearby trees if the raptors hitched rides. You know to smash hictch-hikers.

  • Why people always think that Dinosaurs were stupid? Why? I don't get it... Those raptors hunted in packs and were so effective in hunting down animals... The only thing human can do is extinct themselve..

  • @friendsandrussia because most where stupid, but raptors where found to be one of the rare much more intelligent species from the time... hope that answers the question?

  • @cam20091 It was not really a question, it's not because their brains were small that they were stupid. It also depends on how to use your brains; most species survived or even ruled the planet for mor than 10 million years each, the most important thing in history is to survive I guess, so they're not stupid at all..

  • @friendsandrussia yeah i get where you're coming from but most of that is from instinct and i mean come on take into acount that one of the dinos that was said to have a small brain was a t-rex a huge head and a small brain means it couldn't calculate quickly but its size and instinct made up for it, so yeah some where stupid on acounts of intelligence but instinct is all they needed in those days.

  • @cam20091 Hmm it's not only how big the brains are, it's also how you use it, in what kind of way... Maybe dinosaurs used it very effective... Of course, we are smarter then them, but should we be proud that we are so highly developped; I guess it would seen much better for human if we weren't so developped and destroying the nature...

  • Raptors communicated using hand gestures... Isn't it just a guess? Paleontology ≈ science.

  • Cool video, but the attack of the raptors is not realistic. The raptors didn't use their large claws to cut like in the video. Take the claw of a bear and try to cut through the skin of a crocodile. The raptors use their claws to try to stab their victims in the throat, so they would drown in their own blood. This video is really cool, but it got nothing to do with the reality.

  • @93snakehead dude raptors can cut in edmontosaurus skin. edmontosaurus was not as thick as a crocodile and bears claws were not for ripping they were for climbing or digging up roots or tripping prey not for ripping raptor claws were for

  • raptors fears none exceapt the T-rex T-rex is king

  • "We know that the raptors communicated with hand gestures."

    Why doesn't anyone seem to know that the smartest dinos were only about as smart as an emu? And Edmonto wouldn't have just stood there!

  • well then that T-Rex needs to get FIXED! (T-rex in the distance's yelps then whines)

  • This program is so shit, I can't describe. What a pile of over-dramatic crap.

  • when your marking territory I'M THINKING DOGS! Cats??????????

  • is Edmontosaurus the capital of Albertasaurus?

  • @MrOTK95 lol, that's exactly why it would have been so distracted by it XD

  • Ya gotta admire how pack hunters can take down such massive prey. Wolves are a few tens of pounds lighter than a moose or caribou, but the raptors were often outweighed by several tons by the hadrosaurs.

  • they have no idea of WHAT?? WHAAAAAT??

  • yup i did it was really grose!!!

  • okay, Dromaeosaurus claws couldn't damage the scales of a 4-ton hadrosaur; no evidence of this described event exists anywhere (literally no evidence of Edmontosaurus-Dromaeosaurus predation or gregarious behaviour in this genus); the behaviour of attacking a non-territorial herbivore is just baffling. Think for

  • I noticed man that herbivore is fighting hard

  • This is pure speculation! Even prey animals today run like hell and kick like a bitch.

    Many times the predator goes away hungry, crippled or dead.

  • lol I bet the raptors were like

    "NO FRED!" YOU BASTARD!

  • SWEET!

  • I hate how they can sound so smart with what they know but then they make a dinosaur look so stupid.. like yeah it's going to just stand there outnumbered and die... i'm pretty sure it would've tried running for it instead of just standing in the middle this whole time....

  • this is fuckin awesome!!!!!!!

  • I love how paleontologists say Dromeo"sore"us on TV, what about "sawr"?

  • Sif the Edmontosaurus would just hang around the same spot to get eaten. Stupid video.

  • @RiffRaff3169 dude there is raptors all around them and if you watch the next clip he does run and kill them with it's tail so don't say how bad the video is after you see the whole thing!

  • Jack Horner was WRONG.

  • That edmontosaurus put up such a pathetic fight. It just stood there and took it.

  • @daniel7899999: I too would think that they would fight much better in reality than just standing there and receiving alla that damage without doing much damage by him/herself.

  • @daniel7899999 you need to see the next clip where he runs and uses it's tail and kills many raptors!

  • why this raptors dont have feathers?

  • ahh so dinosaurs did live in pangea

  • @96stewie96: The whole continent's name at that time WAS Pangea. Of course every dinosaur lived when Pangea still existed : /.

  • its been proven that raptor claws on there feet can't rip through skin but can stab it so i dont how you got that result

  • @Tamatoy That doesn't make sense. If they can stab it, they can rip through it. Like a knife. What do you mean, exactly?

  • @ilovemyman001 there claws don't have sharp thin edges like a knife instead they were used to go for the wind pipe to make the dinos stop breathing then wait for it to die but if they went for something like an ankylosaurus there claws would brake off because the skin is as hard as a rock

  • @Tamatoy Oh, of course. Their claws wouldn't even penetrate the skin of an Ankylosaurus, much less rip through. Still not understanding what you meant in your original comment. There weren't any Ankylosaurs in this particular video. Unless you were responding to someone else...

  • @ilovemyman001 there claws arnt like knifves there like... spears. well thats not a good way of putting it but theres not enough muscle to push down on skin like ours they just go deep enough for the WIND PIPE to make them stop breathing.

    its just jump, stab and wait for it to die end of story!

  • @Tamatoy So you're just saying that they can tear through the skin of the neck and not the back, where there's more skin?

  • @ilovemyman001 Jesus, they cant tear through skin at all they r not like knives

    full stop

  • @Tamatoy *sigh* Never mind. You're not understanding what I'm trying to ask.

  • poor Edmontosaurus.....

    auch!!! O.o

  • Hmm... I figure the edmontosaur got separated like this:

    Okay, stay focused. Stick with the herd...

    Ohlooksomethinshinygonnachasei­t :D

  • the edmontosaurus rock the house

  • DID ANYONE ELSE NOTICE THE EDMONTASUARUS CAUGHT A RAPTOR IN ITS MOUTH FROM 6:25-6:35????

  • @AmericanMan44 Yeah, it grabbed it and tossed it away :D

  • @AmericanMan44 I did!

  • edmontosaur "where am i? probably still where i am yesterday?"

    raptors " boys, we got ourselves lunch....move on2.."

    t-rex " this is my kingdom..you live in my rules..but i feel terrible so you can have the tail.."

    did the rex even live at this times?

  • Jurassic Fight Club totally has better CGI special effects than Walking with Dinosaurs

  • WTH is this TV14

  • I hate food

  • why is everything in alberta dakota and wyoming

  • I hate when these programs make assumptions sound like facts and I HATE that dromaeosaurs HAD to have been pack hunters. There is no evidence of that. Though I like the idea lets face the facts, the only pack hunting animals we know of are all mammals.

  • @centrarchid

    Actually there is, particularly Deinonychus. Deinnonychus was orignally thought to be a solitary hunter. They found an animal called tenontosaurus, which is similar to Edmontosaurs (not the same thing) that had been killed by Deinonychus. they found as many as 80 teeth in the bones and for a solitary hunter, losing that many teeth at once would be terible considering deinonychus has about 90. On top of that many raptors have been found together.

  • @cretaceousisle The presence of dead deinonychus together at a feeding site doesn't mean they hunted together. Vultures and crocodiles feed in groups but aren't pack hunters, the same may be true for deinonychus.

  • @centrarchid

    Yes but they found far to many lost teeth in many specimens for there to be only one animal. Scavening couldn't have occured because if that had happened then the bones would not have had slash marks along them in such a exstensive amounts, which only occurs during hunting. I didn't mean they just found them together, that could mean anything. They found them near the bodies of the large herbivores, clearly smashed by them.

  • @centrarchid

    I'm not saying your wrong, I'm just saying there is evidence to back it up... plus the slash marks found on the bones suggest they may have hunted large animals, far to large for a single individual to take on, even if it attacked again and again.

  • edmontosaurus ..... *sigh* ITS A TRAP!!!!!!

  • OMFG ITS RAPTOR JESUS!!!!111

  • 6:30 nice catch

  • "The evidence tells us he has become separated from his herd." What evidence? A fossilized Post-It note saying, "BRB food"?

    "Scientists now know something else: raptors communicated using quick hand gestures." Yes, one finger meant "fastball", two meant "slider", and three meant "kill and eat this guy".

    I know this show is for entertainment rather than education, but I'd like to know where they're getting their facts.

  • @DrThunder88

    I agree, a lot of what they're saying is bullshit. How in the hell do they get hand-gestures from fossils? I just really want to know, and I want to also know why they even mentioned it, when it had nothing else to do with the fight. We don't see the raptors using hand gestures or anything.

  • @RonnieKane

    Its a pack thing, wolves do it, lions do it, birds sometimes do it. the idea comes from that, and that they had the brain copassidy to be able to do that. But your right there is no physical evidense.

  • @cretaceousisle There are a lot of mammals that do it, only a couple of birds. Dromaeosaurs while smart for their time were not as smart as modern day birds or wolves so I tend to think they lacked the brain power to form complex wolf-like social structures. Maybe something more like piranha who just attack in uncoordinated masses.

  • @centrarchid

    I suppose, its mostly comes from what thy got from catscans of the raptors skulls. I don't know if they could or not but it sounds possible to me. I can't see them acting like pirhanas because they just don't fit the requirement for that kind of life style, way to fragile. A Pirhana can take a lot more abuse then people give them credit for and have a water advantage. I do think they'd continue atacking after blood has been drawn like Pirhanas do but in a diffrent way.

  • @RonnieKane

    As for why they mentioned it... just a fun fact I geuss. All I know is they took catscans of there skulls and made a CGI image of what the brain most likely looked like. So its hard to say whether thats enough to prove it or not. All I do know is they saw there was a lot of space for an advanced brain (for the time) so its possible. They did the same with the T-rex and said it was quite smart too, for a large theropod anyway.

  • @cretaceousisle

    You've got good points, and I'm not denying that they are smart at all, it just seemed like hand gestures were a bit out there. I'd like to know how that was suggested. I'd understand body language, such as baring their claws or even pointing at something, but I'd take vocal signs as a more likely form of communication, since they seem very flexible with sounds.

    Though it does fit for stealthy creatures, so it's up for debate, it's still out of place for this episode.

  • @RonnieKane

    I agree, I would expect more of stuff like pointing with there snouts and stuff like that. I don't know exactly know how smart they said they were so its hard to say how the idea came. My geuss is from the catscans but I think they also came up with idea from watching other pack hunters after confirming the theory and found most pack hunters have some kind of comunication. The main thing to consider is the size (or mass) of the brain compared to the body to determin intellegence.
