The Truth about Killer Dinosaurs: T-Rex vs Triceratops Part 2

[andrewrebullar]

Lol about 3 men, 30 poodles..... And a chuawa

[beylader231]

the theory of T-rex was a full scavenger is not possible if it was a full time scavenger it didn't need its 6000-8000 pounds and 35000 newton bite

[A31Chris]

would of had a bite force of at least 4 tons or 35,000 newtons. of course this means... absolutely nothing to me LOL

[DrAnnoyed]

6:31 thats the troll scream sound from LOTR

[Yceb0x]

@DrAnnoyed O_O I wonder if Peter Jackson got that patented.

[WarriorX9000]

Doesn't everyone know that a T-rex is both a Hunter and a Scavenger??

[MrDBarch]

I like this series, but they seem to make a lot of claims using flimsy, if any, evidence. Simply saying that those marks were TRex bite marks, and showing how the shape of the hole matches a TRex tooth, doen't make it so. it simply shows that it might be, or could have been bite marks from a TRex. Many things can happen to a fossil over 85mill years; holes can come from any number of causes. Show us the concrete evidence, not just fanciful conjecture..

[A31Chris]

@MrDBarch I have to say that your disagreeing with these evidences comes off as more fanciful conjecture than what they are presenting here. You can see it right there, its pretty straightforward. STRONG evidence supporting T-rex attacking a live Triceratops. Absolutely concrete? Hmm I guess not but very very compelling. I'd say high 80s percentage wise of probability. Your almost complete dismissal of it comes off as more flimsy than what you claim their reasons are.

[Tahkaullus01]

Florida has Alligator control? WHERE THE FUCK WERE THEY WHEN I WENT DOWN THERE FOR A HOLIDAY?! Seriously, there was one lounging around not a few feet from the house we were staying in!

[4lifebballplayer]

@Tahkaullus01 yeah well there are quite a lot of them and they can't get every single one.

[Tahkaullus01]

@4lifebballplayer FOUR FEET AWAY!!! AND KATRINA HIT ON THE DAY I LEFT!!! GOD HATES ME!!!

[masterjuraya1]

i think crocodile is more relative to t rex not alligator

[4lifebballplayer]

@masterjuraya1 alligators and crocodiles are in the same family and since a crocodile has a longer, thinner snout than an alligator an alligator has a more similar jaw structure to trex.

[Wushu17]

Most people have trouble finding their keys and yet a paleontologist was able to find the missing tip of a triceratop's horn that survived a trex attack. No, its not like the triceratops left the scene of the assault, it stayed in the area and eventually died of old age right next to the broken tip where science was able to find it without a hitch. What if the triceratops carried the tip with it all that time? Come on, lets not be silly here..

[PivotXL1]

Difference between a rhino and triceratops horns are that the triceratops has horns made of bone.

[FlyingAlchemist]

Hey! What is the bite force of humans? Did anybody asked before?

[viceisthename]

@FlyingAlchemist About 200 pounds :)

[FlyingAlchemist]

@viceisthename O_O Imp... Impossible! That much? 200 pounds!? You're clearly kidding me!

[viceisthename]

@FlyingAlchemist It's true... I saw a documentary about bite forces, and they brought in a regular person and he bit a few pounds over 200 :)

[FlyingAlchemist]

@viceisthename And here I thought that we humans were just a bunch of sissies.

[viceisthename]

@FlyingAlchemist Haha

[FlyingAlchemist]

@viceisthename XD

[geniemist]

this is a show for kids...wheres the adult version?

[psb752]

 in a show this uploader (Mrjohn5533) uploaded called clash of the dinosaurs, nearly every episode all archaeologists say that triceratops would have won if they got into a fight unless t-rex had a partner.i havent watched part 5 but if it ends up that t-rex won its bull shit.(im a very big triceratops fan)

[killchoi091]

i take it back....hes the funniest narrator ever....even if im still a little anoyyed at his voice xD

[kitteesPJs]

@killchoi091 The narrator is Bill Oddie—cast member and writer of the only tv comedy known to have killed a man by making him laugh to death. The show was called The Goodies and it was a smash hit in the 70's (I was only a kid but I thought it was wicked funny). I can forgive his narration thanks to the good memories he added to my childhood. ;) (Besides ya gotta give some props to someone who can commit manslaughter by laughter. :P)

[killchoi091]

@kitteesPJs ohh

[Kailyn16]

"that's about 3 men, or 30 some-odd poodles... and a chihuahua" haha XD

[TheProjektcc]

t-rex is far too large to be solely a scavenger. All large predators no matter what type must consume a certain amount of meat a day or they will go hungry. Even lions require a large amount a meat per day. An animal as large as t-rex could not simply rely on stumbling upon a dead Dino carcass.

Also trex lived at a time where the prey was heavily armored. This is why he evolved such a powerful head and bone crushing teeth to defeat armor.

Scavenge could just eat the soft belly of a carcass

[TheThunderduck]

Gee, I wonder what the curator of the Creationist museum would say about this ? I saw an interview with him where he says unequivicably, with proof, that T-rex was a vegitarian. His teeth are designed to strip leaves from plants don't you know.

[turboguppy]

Look, they're just trying to get an approximation. Obviously T-rex's teeth were NOT made of steel either. As for being a scavenger, almost all carnivores will scavenge to some degree. I doubt T-Rex was soley a scavenger, as most theories point to some pack hunting ability, and ambush hunting.

[ironychan]

@turboguppy I think building life-size working metal dinosaurs and using them to destroy cars falls under the "shut up, it's awesome" clause.

[siewmj1]

@turboguppy true, fresh meat are always better than rotten meat. All carnivores are opportunisitic, as long as they have the tool to kill, they will hunt !!!!

[Yceb0x]

@turboguppy Teeth maybe not, but a T-Rex's skull on the other hand was as strong as steel.

[XxComablackxX1937]

The scavenger theory for T-Rex was just stupid....all predators are part scavenger but there is no doubt the Rex was a powerful hunter. 

[MsDjessa]

@XxComablackxX1937 Yes i think the healed scar on the triceratops pretty much proofs it. I mea i doubt it attacked a healthy fully grown adult triceratops unless it was desperate, but young ones and injured, most likely.

[PivotXL1]

@XxComablackxX1937 Yes, but unlike most animals he can scavenge just as well as he can hunt. He has the ears to hear a small bird many miles away plus the sight of birds. Also, a nose that is equally as powerful.

[xenos12500]

@XxComablackxX1937 actualy there is a theory that it wasnt THAT good at running :3 so if it were to hunt its prey would have to be VERY close by

[CHADE47lol]

@xenos12500 T-rex was slow but the Dinosaurs it hunted are slower like Triceratops,Ankylosaurus,Anato­titan & Edmontosaurus so it didn't need to get that close.

[Yceb0x]

@XxComablackxX1937 Not necessarily, they did have fairly decent reasoning behind why they thought he was a scavenger at first. The rules of wildlife and predatory instinct has always been the same: Although you may be big, strong, and tough, go for the easiest pick before tiring yourself out with the larger ones. (After all, another predator might try and steal your catch). They estimated that if T-Rex ran at 38-40 mph and tripped (or was knocked over in some way), his ribs would be crushed...

[Yceb0x]

@Yceb0x (continued) immediately on impact and thereby crushing his organs. Then after sliding for nearly 50ft breaking his neck. Even at 25 mph the damage would still seem fairly catastrophic (Although at say 15-20 is wouldn't be so critical). Assuming small, speedy prey was what he hunted, they figured he stole meals from other smaller carnivores or scavenged what was left. The problem was that they didn't think that not all good prey was fast (either in the brain or on foot) for example...

[Yceb0x]

@Yceb0x (continued) dinosaurs like Torosaurus (mini-Triceratops cousins) did not run very fast and were no doubt slow to respond. But in the end, like you said, all good predators are opportunists. They hunt when they can, steal when they please, and scavenge when it's available.

[A31Chris]

@Yceb0x Thats their estimation. And while T-rex probably moved nowhere near that fast they really have no way of knowing how truly resilient these animals were when it comes to falling over etc. We now know T-rex hunted. If the species was so vulnerable to falling and not being able to get up I dont think it would of been as successful a species as it was.

[1215beastman]

@XxComablackxX1937 ywell i wouldnt say ALL predators were scavengers part time

[Evanest25isBack]

I tought a bird is a more closer relative,of course testing a bird's bite would have been pointless.

[TheTyranno11]

@Evanest25isBack they are. the reason why alligators, birds & dino's like T-rex are closely related is because they all share a common ancestor- the Archosaurs.

[Ins3ktz]

Wouldn't the trauma from an injury so close to the head of the Triceratops at least traumatize it?

[TheTyranno11]

10:56- Haha, thats pretty funny =D

[BrontoSmilodon1]

The first part reminds me of animal face when they had to test the bite strength of animals

[Junketh71]

Why an alligator? Why not a crocodile, I wonder?

[BrontoSmilodon1]

@Junketh71 I know right, but they probably didn't want to waste money on a trip to africa, asia, austrailia, or cuba

[Junketh71]

@BrontoSmilodon1 Yeah, you're probably right, but I remember the Discovery show "Feeding Frenzy", when they tested the bite strength of crocs and gators on a gator farm or some place like that. Couldn't they have done this here as well, I wonder.

[BrontoSmilodon1]

@Junketh71 I guess so but I don't think they knew about that info and were probably more familiar with alligators than crocodiles in the US.

[Junketh71]

@BrontoSmilodon1 I guess you're right. It would still be neat if they have used a crocodile instead.

[dragonstormx]

@Junketh71

Not sure, but pound for pound, the gator we have in America have a stronger bit.

[Junketh71]

@dragonstormx Well, if you say so; I don't know about that for sure.

[johnniwonton1976]

Did he say "CRIKEY!" LOL Steve Eriwn lives on!
