Umm....how could Giganatosaurus average 46-47 feet in length when the skeleton on display is 43 feet long? And I dont know about that 10 ton weight estimate. It seems a little excessive, seeing as the upper end limits on theropod weight estimates are at 8 tons.

Question Honkie Tong. Why do you try to debunk everything I say?
from Sean.S, age 13, ?, ?, U.S.A; July 31, 2001

Look Honkie Tong,first of all,we're talking about an animal that weighs 10 tons,with a skull about 6 feet,and 46-47 feet length on average, vs. An animal thats 39-43 feet in length-weighing 7 tons on average. And look at the skull,of giganotosaurus compared to an average sized t.rex skull! Also,the openings on the sides,of theropod skulls,are used to incase muscle. Judging by the size of the openings on the skull of giganotosaurus,i'd expect a pretty good bite.(Now i'm not saying it could bite through bone,i'm saying that it had enough firepower to kill the likes,of horned-dinosaurs and hadrosaurs alike,and certainly a t.rex.) I suppose a t.rex could beat giganotosaurus,if it suprised one. But if a t.rex made its presence, known to the giganotosaurus,the chances are,t.rex is going to lose. Let me know,when you'r done researching,live dinosaurs!

Liopleurodon vs sperm whale

A liopleurodon would most certainly win this fight. For one thing, a lio's mouth was built to tear out enormous chunks of meat in one bite, rather like a T. rex. Also, lios were big game hunters. They hunted other large marine reptiles like Shonisaurus. A whale is not. Some people say that they are, because they hunt giant squid, but really when you look at weight the sperm whale dwarfs the squid and is many times heavier. If it really was a big game hunter it would hunt other whales. As for that thing about lio not being able to cope well with cold water, I disagree. A great white shark is cold blooded, but because of it's size, it can withstand very cold temperatures far better than most other sharks. This would certainly be true for a 100 ton+ lio. And furthermore, a lio is larger.

Alectrosaurus And Albertosaurus And Daspletosaurus And Tarbosaurus Are Some Of The Dinosaurs In Tyrannosauruses Family.
from euoplacephulas, age 8, Alta, CA, USA; July 30, 2001

"While it is true that allosaurs like _Giganotosaurus_ hunted simpler-brained and less armored prey than _Tyrannosaurus_, but both were very large and capable of killing each other. If we matched them up (which, remember, would never happen naturally because they lived on different continents and in different time periods) I would expect whoever got the first bite/slash in to win. That is, the winner would be different each time we matched them up (_T. rex_ probably wouldn't win every time, and either would _G. carolinii_)."

Granted, the situtation seems pretty untentable until we delve into the morphlogy of the animals. This will allow us to discover which animal would be a likely winner when the size is similar. For example, a fight between a 43-foot Giganotosaurus and a 40-foot Tyrannosaurus is a bit hard to find the winner in this case. (In this case, we define the winner as the animal who has a better chance of defeating the other). As for contestents of similar size, it will be the abilities bestowed upond the animal by its morphlogy that will be the determining factor.

Now, if we look at the morphlogy of Tyrannosaurus, we find that he was considerably more intelligent, faster and agile than Giganotosaurus, which will give him somewhat of an large advantage against his adversary. Also, the fact that he had a far more effective bite also comes in largely into play. It's also highly likely his heavier-built body would also make his tougher. With his greater agility, speed and bite, Tyrannosaurus has a very good chance of getting in the critical first opening bite to the battle. That done, it'll be downhill for his opponent due to the effects of that kind of bite.

If Giganotosaurus bit Tyrannosaurus, it would be a bad thing, but not likely to be fatal to the Tyrannosaurus unless a major artery was gouged or something. Tyrannosaurus had well-protected organs and eyes, so the chance of a critical hit would not be high. Giganotosaurus could not use it's mouth to as great as effect as Tyrannosaurus, and that'll count greatly in this battle, as these two animal relied soley on mouth-power to take out their prey, and I'm saying that fairly, not because Tyrannosaurus is my favourite. It's weapons and abilities that matter here, and Tyrannosaurus certainly has the advantage in both areas. Not that I'm saying he'll win everytime, but I'd expect him clock up a very good kill-loss ratio, somewhere in 6:1.

So this is my verdict, Tyrannosaurus would win!

Actually, I believe the prey Tyrannosaurus commonly hunted in his habitat gave him a tremedus advantage in a fight over Giganotosaurus.

Well, the prey Tyrannosaurus had to hunt was by dinosaur standards, extremely sophisticated and advanced, not to mention dangerous. Like Triceratops. As the result of that, Tyrannosaurus had to be agile, fast and quick-thinking to catch his food. As a result of that, his brain was about twice the size that you'll expect in an allosaur his size. He needed the brain power to provide him with the mental and physical agility to hunt such prey. Even his body suggested adaptations towards speed.

On the other hand, allosaurs like Giganotosaurus hunted mainly stegosaurs and sauropods. These prey were quite different indeed from the prey Tyrannosaurus hunted. They were simpler and considerably slower, less agile and certianly less complex. The Allosaurs didn't need too much brainpower, speed or agility to hunt these animals. As in the case of sauropods, Giganotosaurus simply evolved his size to take these animals on. Granted, sauropods are not easy prey but they are an entirely different ball game altogether. And that's going to count against him.

Also, tatics matter here. In Giganotosaurus' case, he hunted prey that could not easily outpace him. Thus as such, he didn't deen it necessary to have adaptations to be capable of killing or really seriously injuring its prey in a single bite. He would have plenty of chances to strike at the animal again without the fear of it running away. All he had to do was to stay out of the way of any defences it might have (spiked tail, whip tail...etc...etc)

Tyrannosaurus on the other hand, faced prey that could outrun him if he didn't get it right within the first few moments of the hunt. Granted, he could achieve higher speeds than any of his potential prey items but he could not keep them up for longm after which the prey would outdistance it. If he did not bring it down within the window of time where he could still keep up with his prey, he will stand a very good chance of losing it. As of so, we see Tyrannosaurus packign adaptations for bringing down the animal as quickly as possible. He had to develop extremely strong teeth, an incredibly strong bite and a bunch of other subsystems like steroscopic vision to bring home the bacon in the short period of time. In other words, he was designed to kill within the first or second bite.

In a fight, Giganotosaurus will be put at a serious disadvantage mainly because Tyrannosaurus will present a fast and agile target, something he was not adapted to fight. On the other hand, while Giganotosaurus in no way ever presented part of a natural diet for Tyrannosaurus, the profile of Giganotosaurus better fits that of the prey he was used to hunting. Tyrannosaurus will certianly have the advantage in a fight given by his adaptations towards hunting fast and agile prey like his high speed, incredible robustness and most of all, an incredibly powerful bite. And this is the main reaosn why T.rex will easily win. He was designed to take out large animals as quickly as possible. It is ability and weapons that matter here, not size. And Tyrannosaurus has the advantage in both areas.

So there you have it, the habitat of Tyrannosaurus gave it quite an advantage over Giganotosaurus.
from Honkie Tong, age 17, ?, ?, ?; July 26, 2001

Allosaurids and Tyrannosaurids seem to have different methods for dispatching their prey. This is most likely due to the fact that they each preyed upon very different animals.

The Allosaurids are slashers. Their teeth are like that of blades, being thin and serrated. Allosaurs were probably "ambushers" as they were not capable of inflicting precise bites (they lacked stero-scopic vision). It has been theorized that they would ambush their prey at close quarters, inflict a wound on the thigh or other meaty area, and pull back before their prey could react. They would then wait at a safe distance for their prey's life to bleed away.

T.Rex on the other hand, was a chomper. Its teeth were more akin to spikes or pegs; deeply rooted and robust. They were capable of smashing through muscle, tendon and bone alike. T.Rex probably employed a "pursuer" hunting style, taking advantage of its ability to inflict precise bites due to its stero-scopic vision. Running alongside its prey, it could bring its jaws to bear and deliver a crippling bite. The prey animal would collapse from shock and the sudden loss of mass, and tyrannosaur could feed shortly after.

"larger-younger relatives of giganotosaurus keep turning up"

Erm, actually much larger specimens of T.rex keep turning up also :)

"Also,we have found some bones,of sauropods and iguanodons,with deep grooves,apparently made by allosaurus!"

Actually the grooves were pretty shallow, not deep.

"Although not bone crushing,those bite marks are pretty hellish. "

Nope, it's really peanuts compaired to what T.rex can do. He can do 13 TIMES more!

"If an allosaur could do this,imagine what a giganotosaurus could do! "

Actually the morphlogy of Giganotosaurus skulls indicated they had a rather weak bite for their size, even weaker by proportion than Allosaurus. Giganotosaurus didn't bite too much harder at all.

"Trust me,those jaws would do more than a little nip,to a t.rex! "

The question is not what they can do to T.rex, it's what T.rex WILL do to them...:)

"I bet with jaws like that,you could hold a t.rex at bay. "

Actually these are the last type of jaws you'll like to hold T.rex at bay with. Not to mention T.rex could simply bite the jaw off and remove whatever you are using to "hold him at bay". Nope, with an animal capable of doing so much damage, a tiny two foot advantage and a lightly-built skull is NOT what you will want to have between him and you.

"The teeth alone are big enough,to do some sizable damage to a t.rex. "

Once again, the question is not what they can do to T.rex, it's what T.rex WILL do to them...:)

"Plus,we have the habitat vs. habitat advantage. I'll say more later."

"Bacteria probably inhabited the serrations of its teeth,therefor,its prey probably died of infection. "

Actually, the mouths of all carnivores are not particually clean, but few have actually adapted this to kill. Allosaurus was not one of them. Unluckly or weak prey may die after an Allosaurus bite, say three weeks later? A Tyrannosaurus septic bite is expected to kill in seventy four hours, even if the prey is healthy. Adapations for an extremely septic bite is almost exclusively found in Tyrannosaurus, not even other Tyrannosaurids. Allosaurus certianly did not rely on this as a tatic, unlike Tyrannosaurus.

here is a revised version of Tyrannosaurus rex vs. Giganotosaurus carolinii. I must say it's not perfect, but I relied on facts(and some of my own theories:-) ), not fiction. Do not rely on this for pure facts, for it may not be all fact.

Tyrannosaurus rex vs. Giganotosaurus carolinii

The Tyrannosaurus rex stood by a lake. He bent over to drink some water. A large shadow stood over the lake. The Tyrannosaurus stood up and growled. He turned around to see a preditor larger than himself. A Giganotosaurus.

The T.Rex narrowed his eyes and looked at the large preditor. The Giganotosaurus nipped at the T.rex. The T.rex roared at the Tyrannosaurus and charged toward him, his mouth opened wide. The Giganotosaurus dashed out of the way. The T.rex managed to bite his tail, crushing the Giagantosaurus's tail vertebrae. The Giganotosaurus swiped his tail at he Tyrannosaurus rex. The T.rex only got the tip of his tail, but it was enough to enfilict pain to the Giganotosaurus when he whiped his tail at the T.rex.

The Giganotosaurus wasn't very smart. Infact, his brain looked like a withered banana. The T.rex's brain was larger and wider, giving him the advantage. The T.Rex's teeth were also disigned for a crushing action. Giganotosaurus was designed to slice, again giving T.rex the advantage.

The Tyrannosaurus charged for the Giagantosaurus again, this time from the side. The T.rex sunk his teeth into the Giagantosaurus, breaking his ribs. The Giagantosaurus fell to the ground. He roared and tryed to get up. His arms were to short, though, even shorter than T.rex's arms. The T.rex began to feast opon his treat. T.rex won!

Now, hopefully, that was accurate. If it wasn't, please tell me what wasn't accurate, and what would be accurate.

An excerpt from the "The Predatory Dinosaurs of the World" by Gregory S. Paul (p. 384):

*DEINOCHEIRUS MIRIFICUS Osmolska and Roniewicz, 1969
TYPE-ZPAL MgD-1/6
TIME-early Maastrichtian? of the late Late Cretaceous
HORIZON AND DISTRIBUTION-Nemegt Formation of Mongolia

.Type
TONNAGE- 6-12

This is one of those enigmatic, poorly known dinosaurs that has us dinosaurologists all agog and drumming our fingers as we hope for more to show up. Only the arms and hands are known, and they are 2.4m (almost 8 ft) long. Of course, some have not been able to resist comparing this set to the forelimbs of Tyrannosaurus rex and extrapolating fantastic sizes for the owner, but this is a false comparison because tyrannosaurs have unsually small arms for their size. Much more pertinent is John Ostrom's observation of 1972 that Deinocheirus forelimbs are, bone for bone, much the same as those of ornithomimids. This includes the long thumb metacarpal, and the slenderness of all the long bones. However, the claws are more robust and strongly curved. If this is an ornithomimid, then the forelimbs should be relatively long relative to the body. But this still must have been an enormous animal. In the mass estimates, it is assumed this had about the same mass-to-scapula relation! ship as did small ostrich-mimics. What it looked like and what it did is anybody's guess, but its hands, which are more advanced looking than those of Harpymimus, suggest that it was a toothless ostrich-mimic. I place it as more primitive than Ornithomimus because its humerus has a bigger deltoid crest. The great claws may have evolved for non-predatory feeding purposes, for they are too blunt for killing, but would have been effective defensive weapons. Whatever it was, Deinocheirus was a rare and bizarre member of the Mongolian fauna."
from Sauron, age ?, ?, ?, ?; July 19, 2001

If a Bull Mastiff fought with a Great Dane, the Great Dane has a greater reach (longer snout) and a size advantage than the Bull Mastiff (shorter snout, slightly smaller) But in all cases, the Bull Mastiff will rip the guts out of the Great Dane, nonwistanding any longer jaw or size advantage. This is the exact condition we find in Tyrannosaurus vs. Giganotosaurus.

Dear all

I have just joined Dino Science Forum and I thought I would let you all know about an up and coming webcast my museum is launching next week.

>From the 23 to 27 July, my museum will be hosting a fossil-dig webcast from the central Australian desert. The webcast has been specially designed for students aged 6 to 18 and will allow them to link to palaeontologists uncovering the remains of Megafauna. Megafauna were huge animals - giant Kangaroos, giant birds and giant crocodiles etc - that roamed Australia for millions of years. Fossilised bones of these animals have been found all over Australia, however there is a very rich site in the middle of the Simpson Desert, in a place called Alcoota.

Next week Australian Museums On Line will be setting up a satellite link to Alcoota, which will allow people from all around the world to email questions to paleontologist from the Museum and Gallery of the Northern Territory, who are currently working on the site. So feel free to log on and have a look at the site now, because aside from the webcast, you will also find a host of educational games and resources about Australia's unique megafauna.

No, you are wrong, Giganotosaurus didn't have a septic bite.
from stegosaurus, age ?, ?, ?, ?; July 18, 2001

"Giganotosaurus may not have had bone crushing jaws, but in return, it had a bigger head, with a heck of alot more teeth! "

That's a poor tradeoff for a heavily built skull and ten more teeth (rex has 50, Giganotosaurus has 60) . Giganotosaurus' larger head was more fragile and his bite could not do anywhere near as much damage as t-rex. T-rex is certainly and clearly superior in this area, no matter what you may say.
from stegosaurus, age ?, ?, ?, ?; July 18, 2001

I'm no t-rex fan but I don't think t-rex will coem out worse for wear when he charges giganotosaurus head on. For one thing, t-rex had a stronger, tougher and stouter skull than giganotosaurus, and he had much bigger and stonger teeth too. I don't see how it would be like running into a blender. t-rex can easily bite a huge part of giganotosaurus' skull off, and t-rex bites cause far more damage. In fact, if giganotosaurus saw t-rex rushing in, I think he better backpedal and run away! And I don't think a greater reach is gonna help. If giganotosaurus has to bite t-rex, he will have to come into contact with t-rex, and if they are touching, it means that t-rex can bite him too. If t-rex bit giganotosaurus on the skull, it would be a very bad thing as giganotosaurus' skull was quite lightly built and t-rex would have no trouble biting through it. A huge hunk missing from giganotosaurus' skull will be big trouble for giganotosaurus. Meanwhile, t-rex who has longer lower leg bones than giganotosaurus would have been faster and can also bite giganotosaurus and then move away before giganotosaurus can attack. t-rex can stand alot of bites from giganotosaurus because giganotosaurus bites are not as serious (only flesh wounds) and he was stoutly built and therefore quite tough and hard to break. On the other hand, giganotosaurus couldn't effort to take more than three t-rex bites. One t-rex bite would have done the damage of more than seven giganotosaurus bites, not to mention the bones broken with it. giganotosaurus wasn't designed to take alot of damage, unlike t-rex, and that's going to count greatly against him. And not to mention he was slower and dumber, it seals his fate in this fight.

Allosaurus didn't have huge hands! If he fell, he'll take alot of damage and most likely break his arms too (for goodness sake, his arms were only one and a half meters long, well in the range for short armed dinosaurs). Allosaurus coundn't effort to fall! Allosaurus couldn't jump too high too. He'll probaly end up like in Honkie's picture.

from ?, age ?, ?, ?, ?; July 18, 2001

If I saw Spino injure T-rex badly with his arms of drive it off I'll believe it. But biting T-rex to death? T-rex had a few good bites in at Spinosaurus and it wasn't even fazed! And when Spino bit T-rex it died? Hellooooo? T-rex bit far harder than any terrestrial carnivore that ever lived, including Spinosaurus. Unless Spinosaurus had a super neck or something, he woundn't have survived that bite!!! And when Spino bit rex in the neck, he broke rex's neck? Hellooo? rex had a heavier and tougher neck than Spinosaurus according to fossils, if T-rex biting harder than Spino could not break Spino's neck, how on earth can Spino biting weaker than T-rex break T-rex's neck??? The movie has obviously slewed reality to make Spino look far, far meaner. And I doubt Spino was as amphbious as in the movie! This movie is nothing but a spino propangada fest!
from Down with Spinosaurus, age ?, ?, ?, ?; July 18, 2001

"If an allosaurus tripped, it's huge arms could probably break the fall.(unlike t.rex) "

Actually, Allosaurus didn't have huge arms at all, in relation to its body. It's arms would be broken in the fall, along with its ribs. T.rex probably rarely fell, if at all (unliek allosaurus)

"2.If t.rex was dumb enough to charge at a giganotosaurus head on,t.rex would come out worse for wear! Giganotosaurus may not have had bone crushing jaws, but in return, it had a bigger head, with a heck of alot more teeth! "

Actally, Giganotosaurus was not designed for the head-on-approach like T.rex. And he had about, what? 10 more teeth? But his teeth were all smaller and were designed to inflict flesh wounds. Tyrannosaurus' teeth were designed to rend flesh and muscle together. Heck, Tyrannosaurus could bite Giganotosaurus' jaw off easily with his vastly superior bite power. Giganotosaurus' longer skull is about as fragile and useful as wet tissue paper when it has to resist a T.rex bite, as with any part of its anatomy.

"3. Although the teeth of giganotosaurus were thinner than that of t.rex,they were much thicker than a sharks teeth. "

So what? Sharks don't prove anything. And Giganotosaurus teeth weren't like sharks teeth at all, you're mixing up another dinosaur.

"4. As far as i know, t.rex did not replace worn out teeth.(unlike the giganotosaurus)"

That's completely wrong! T.rex constantly replaced its teeth. In fact, turnover rate is likely to be superior to Giganotosaurus.

"5.Giganotosaurus had much better reach than any known tyrannosaurid."

That really dosen't matter as a melee is a contact sport. If Giganotosaurus is trying to bite T.rex, he has to do it with his jaw and what is he doing? Reaching T.rex. T.rex can always bite Giganotosaurus' head, and that would be very bad. Giganotosaurus has a longer reach...to death! And it's a what? two feet advantage? pluezzeee! that's one of your weakest points!

"6.Giganotosaurus probably had an infecting bite,just like t.rex"

That's extremely unlikely. Giganotosaurus didn't have any adaptations for that kind of warfare. And you probably don't even know what these adaptations are so you better not mention this again unless you want to look extremely ignorant, more than you already are.

"7.Allosaurids had vision most similiar to a robin. "

A robin isn't a great predator and all the Allosaurids didn't even have steroscopic vision for dept perception. Tyrannosaurus on the other hand, had forward facing eyes and a sizeable optical lobe (much larger than any allosaurid). Tyrannosaurus would have had eagle-vision, and even better. A robin? Man, you gotta beat these guys for me!

"8. Allosaurids had more weapons,than tyrannosaurids"

Who cares if you got the most powerful weapon? All the firepower Allosaurus can muster is not even half that of what a Tyrannosaurus can do when it's not even trying.

". Allosaurids were kinder to each other,and meaner to their prey. "

Who are you trying to appeal to? Barney? Who cares how you behave when you are clearly superior. Tyrannosaurus was mean and that's it. This point is irrevalant (like most of what you say)

"10. Giganotosaurus had a devastating bite,even if not bone crushing. "

Nope, actually the sissor jaws of Giganotosaurus would not have allowed for it. In fact, the paleontologist who discovered Giganotosaurus admitted that Tyrannosaurus was far deadiler in the area of bite.

"11. The superior senses , bone crushing jaws , and construction of t.rex woul! d render it the king of the hunters.(not the king of the fighters) "

All the animals you mention are hunters. And Tyrannosaurus did alot of fighting with one another too, more than Giganotosaurus.

"12. New evidence suggest,giganotosaurus was (46 ft.) long.

Newer and verified evidence PROVES, giganotosaurus was 43 feet long. And did you know the latest weights estimates put Giganotosaurus at 7 to 7.5 tons? No? Well you never did check your stuff.

"13. By the time t.rex was introduced to the playing field, giganotosaurus probably got at least as big as Rigby rex. "

The Rigby rex is likely to be larger than Giganotosaurus by a reasonable margin, but about the same weight as it was leaner and more muscular than Giganotosaurus, prehaps with a slight advantage. Size dosen't really matter though, any Sue-sized rex could take out Giganotosaurus.

". 14. Allosaurids have been around, way longer than any tyrannosaurids, and were around until the end of the dinosaurs."

They were lucky, they weren't sucessful. The group was wiped out and replaced by the Tyrannosaurids up north and it was the splitting of the contentinents that saved the Allosaurids south. If there had been no sea, the Allosaurids would have been extinct a long time ago. It's like in africa, where the lions drove the tigers to extinction in the plains. If it wasn't for the forrests, the tigers whould have been lost. And lions are certianly more sucessful than tigers today (despite being slightly smaller and a great deal meaner, a situtation we find in Tyrannosaurus pund for pound). The Tyrannosaurus on the other hand, rose quickly and live on as the aves today, they are the true survivors.

My favorite dinosaur is Spinosaurus. I thought he looked cool, he was smart, fast for his size, strong, and aggresive. Not to mention huge. The Spino can get up to 55 feet long. He could take on any dino that got in his way. He could definitely take down the Giganotosaurus. But, the Spinosaurus and Rex would be a great fight. Rex has the great jaws and Spino has the massive arms. I'm glad he is in JP3. He is the baddest dinosaur. And yes, believe it or not, the Spino can also take down HHH and stop his pedigree!!!!!!

Tyrannosaurus rex means: Tyrant lizard king. Its huge head was as big as a bathtub. It was a hideous beast about 40 feet long and 15 to 20 feet tall. It had huge sharp strong jaws the size of bananas and were incredibly strong, used for gobbling up other dinosaurs. It's special because it has interesting jaws and amazing speed and incredible height strength and muscle power to make its life longer and nice. It was at the top of the food chain and had nightmarish movement and a terrifying face with 2 huge claws on its tiny hands. It was a 2-legged creature with speeds of 25 collimators ph. It could live up to 100 years. It might have hunted in groups.

"And you can't just assume T.rex ate Triceratops and Carmosarus"

Well we do have evidence that T.rex ate Triceratops. And T.rex certainyl had adaptations to go in, close and personal to do alot of damage, Spinosaurus did not. It's quite obvious T.rex was the predator. I suppose Spinosaurus could have hunted, but never to the degree of deadileness of T.rex.

You can't just assume Spinosaurus ate primarily fish. He could have hunted just as well as T.rex. I happen to have my own theories. And you can't just assume T.rex ate Triceratops and Carmosarus. The only way you can prove these things if you were to go back in time to see a Tyrannosaurus Rex, and then go even further back, and see a Spinosaurus.
And, Spinosaurus and Tyrannosarus Rex never met, so it's piontless to argue about who would win.

T.Rex would kill a Spinosaurus in about 10 seconds. Spinos where lightly built and primarly ate fish (what wimps!). T.Rex hunted stuff like Triceratops and Carmosarus which were really tough and strong. I think the toughest human ever is HHH. He could beat most dinosaurs. He would pedigree a Allosarus, Ultraraptor or a juvinille T.Rex and kill him. HHH is the game.

T.rex a scavenger? Not that's a joke. With legs pertained to walking and arms swung too low they were only good for fishing or tearing up animals already dead and not moving and with a lighter built body that didn't put too much emphasis on strength and with very ungracile legs that made him slow for his size, Spinosaurus better fits the picture of an animal made for scavenging. Now buzz off Horner wannabe.

from Aaron L, age 12, Cherryfield, Maine, USA; July 9, 2001

Don't say anything Damean! I wanna try this one!

You're ignoring the spikes of Stegosaurus was at his rear, he was extremely vunerable from a front-on attack, something, if T.rex had met him (yes yes, I know they never did you purists!), would have known.

And of course, you were wrong about T.rex teeth being small. T.rex's teeth were larger compaired to Giganotosaurus. The average Giganotosaurus tooth was allosaurid type, about 7-10 cm at max. T.rex's had two distinct type of teeth actually, the front nippers who were about 12-15 cm long and stout in profile to make the initinal peneration and of course, his side maximilia that allowed him to crush bone after the nippers made an entrance. The maximilia were about 15-25 cm long and very strongly built with recurve, certainly much bigger than Giganotosaurus. (In fact, T.rex holds the undisputed record for having the largest teeth for predatory dinosaurs). Also, T.rex certainly bit very much harder than Giganotosaurus.

HA!

And now to the fight:

T.rex VS Troodon

Normally, T.rex wouldn't bother with small prey like Troodon unless he was really sure of capturing it. Now, what would have T.rex to attack Troodon is when he had the advantage of surprise. So here is T.rex, waiting innocently in ambush for his favourite Hardosaur prey when Troodon stumbles by. T.rex sees his chance and bursts out of cover. He takes much larger steps and can accelerate faster than Troodon. He's upond Troodon in two quick steps and the Troodon's only hope is to use his agility to avoid his jaw and run for cover where T.rex wouldn't bother. But unfortunately, very powerful neck muscles and steroscopic vision for judging distance allows T.rex to move his massive head extremely quickly and with great accucracy and Troodon is caught. Troodon was never built to wistand 5-tons of force and he is reduced to a ragged wash of torn meat and broken bone in a blink of an eye. T.rex.

T.rex VS Brachiosaurus

I seriously suspect T.rex was smart enough to use his septic bite, but for the sake of an argument, I'll employ another method. T.rex rushes out of cover before Brachiosaurus can react sufficently and bites one of its hind limbs, holding on a bit longer to twist and rip a large amount of flesh out of Brachiosaurus' leg. T.rex then rapidly, and wisely retreats. What is most likely to have happened is that the T.rex bite would have driven down to the leg bone of Brachiosaurus (though is unlikely it could be broken as its too massive) and severed alot of important tendons and ligaments in the path of the bite. Brachiosaurus is effectively hamstrung and cannot rear up (if he could) or turn around quick enough with one useless leg to face the threat. T.rex can either go in to tear more bites from all over Brahiosaurus until he bleeds out or go for the easier option of going for the other leg, in that case, the 50-ton dinosaur is not going to be standing for long and will crash to t! he ground. In either case, the rex is gonna bring him down, and he has the ability to do that. T.rex.
from Honkie Tong, age 16, ?, ?, ?; July 9, 2001

If memory serves, Giganotosaurus had a mouth full of cutting teeth. T.rex had a mouth full of piercing, gouging and crushing teeth with cutting as a secondary function. Naturally, T.rex would have needed and he did have much larger teeth.
from Honkie Tong, age 16, ?, ?, ?; July 9, 2001

*Ahem*
Tyrannosaur teeth were NOT small when compared to Giganatosaur teeth. The largest of Giganatosaurus's teeth perhaps equalled T-Rex teeth, but on the most part T-Rex had the larger dental equipment; along with a superior bite strength.

Whatever happened to the old UCMP Rex specimen? It was gigantic, but known from only one bone; a tooth-bearing maxilla from the upper-jaw that was 29 percent longer than the AMNH type. Size estimates on this individual were around 44 feet long or more. I've only seen scant information on the specimen.

What makes you so sure Triceratops could run at 30mph? Do you have trackways? What is this based on? Triceratops was considerably heavier than Tyrannosaurus by 3 tons and he certainly was not as well muscled in the leg area. We know from a single print that Tyrannosaurus had a walking speed of 17-25 miles per hour (lower and upper estimates), and that's just walking. Even if he put in a slight spurt of speed, he could have made 35 miles per hour? The morphlogy of Tyrannosaurus certianly indicates he was a faster animal than Triceratops or any of his potential prey items in the short run. Tyrannosaurus, being much lighter and bipedial, would have been considerably more agile than Triceratops too. In fact, now studies indicate that Triceratops could not gallop like Bakker used to say, but at best put up a trot like an elephant and hit prehaps 20 mph. Besides, if you used Bakker's estimates of a 30mph Triceratops, you should use Bakker's estimaes of a ! 50mph Tyrannosaurus too! Not to diss the big man, but he does have extreme dinosuar speed estimates. 20mph seems to be a Horner estimate, and you can't pick and paste from different estimates from different people just to suit yourself. Here, I'll show you Stegosaurus ate only insects and was killed and eaten by small lizards, using your pick and mix method.

Fact 1:Insects have small brains.
Fact 2:A Praying mantis is an insect that eats only other insects and was preyed on by 20cm lizards.
Fact 3:Stegosaurus had a small brain.
Fact 4:Therefore, Stegosaurus must have ate only insects and was preyed on by 20cm lizards.

'Nuff said.

An excerpt from "The Predatory Dinosaurs of the World" by Gregory S. Paul (P.273-274):

"GENUS SPINOSAURUS Stromer, 1915

SPINOSAURUS AEGYPTIACUS Stromer, 1915
TYPE - destroyed in WW II
TIME - Cenomanian of the early Late Cretaceous
HORIZON AND DISTRIBUTION - Baharija beds of Egypt

Type
TOTAL LENGTH - ~15 m?
TONNAGE- ~4.0?

This fantastic beast combined tremendous length with a nearly-six-foot-tall (1.6 m) fin over the back. At a possible fifty feet (an extrapolation from the type's incomplete set of vertebrae), this may be the longest known theropod, but claims that this theropod was the biggest of all and massed up to six tonnes are probably overstated. Although the spinal column is a good deal longer than it is in the AMNH Tyrannosaurus rex, spinosaurs are much more lightly built, dilophosaur-like animals. So Spinosaurus probably weighed closer to 4 tonnes. But the lack of fusion between the upper and lower sections of the vertebrae indicate that this particular individual was not mature, and still had some growing to do. Aside from a number of tall spined neck, trunk, and tail vertebrae, only the front half of the lower jaw was ever found, and all are now lost. The lower jaw is deeper, more expanded at the tip, and more crocodile-like than in Baryonyx. The teeth are more conical and li! ke those of crocs too, but, unlike Baryonyx, they are no more numerous than in most theropods. So, just which of the two species is the more advanced is not clear.

The vertebral spines are somewhat elongated over the neck. Exactly how much is not known, but they must have been only a fraction of the trunk's spine height. Likewise, the tail's neural spines were only a little elongated. The size of the fin back was unmatched by other known theropods; the fin of the allosaur Acrocanthosaurus atokensis was probably much lower. Strangely enough, two big herbivorous dinosaurs from the mid-Cretaceous North Africa-the "duckbill" dinosaur Ouranosaurus and the brontosaur Rebbachisaurus-also have tall fins, although the locales and ages of these dinosaurs differ somewhat. Likewise, a number of spectacular fin-backed amphibians and early mammal-like reptiles such as Dimetrodon lived together way back in the Permian Period. Why the evolution of big sails in unrelated animals seems to cluster together is a mystery.

Despite the great size, Spinosaurus would have been vulnerable to attacks from the big allosaurs that shared its habitat."

Ha! Good one Damean! Come to think of it, if T.rex employed the method you stated, it just might be able to take down a Brachiosaur (yes yes you purists, I know they never met). Of course, I wonder if T.rex knew this.

If we T-Rex fans are weak, then you euoplacephulas are weaker. Of course T-Rex was better than a Stegosaurus. T-Rex could EASILY kill a T-Rex, fill it with stuffing and hang it as a trophy. (Ha! I can spell better than you!). If it went after prey, it would most likely kill it. It was a good hunter, though he is not scared to scavenge. That convinces you euoplacephulas! Look at these fights:

T-Rex VS Stegosaurus

Stegosaurus woops at T-Rex with its tail but T-Rex is careful to stay out of range. He rushes in at Stegosaurus' flank before it can turn to bring the tail in and gives it one bone-crushing bite, removing 70 kilos of meat before retreating to a safe distance. The Stegosaurus is bleeding horribly and starts to weaken. T-Rex rushes in and delivers a few more bone shuddering bites and breaks the ribcage of its prey, puncturing its lungs and Stegosaurus soon starts dying, drowning in its own blood AND bleeding to death. T-Rex.

T-REX VS BRACHIOSAURUS

T-Rex rushes out of cover in an ambush and takes a big bite out of Brachy, retreating to a safe distance before the Brachy can respond. T-Rex keeps a safe distance and follows the Brachy, waiting for the lethal bacterial it introduced into Brachy by his bite to take effect. Soon Brachy is suffering from raging fevers and blood poisoning as the germs attack his system. Overloaded, his kidneys shut down and he starts to go into toxic shock. He sinks to the ground 72 hours after the first bite and is too weak to defend himself as T-Rex aims for his now lowered neck. He dies in a bone-crunching crush of T-Rex jaw. T-Rex.

T-REX VS VELOCIRAPTOR

Velociraptor scratches T-Rex, but T-Rex is unaffected because he's so big. But T-Rex lunges forward and catches Velociraptor in his jaws, impaling the raptor on his long teeth. T-Rex slams down with his jaws at about 5 tons of force and almost every bone in Velociraptors' struggling body caught between their shearing action is broken, including the spine. Velociraptor drops dead to the ground from T-Rex's jaw looking like he had gone through a hydraulic press. T-Rex.

T-Rex VS TRICERATOPS

Triceratops charges T-Rex but T-Rex dodges to the side skillfully. Triceratops has too much mass to stop and turn fast and T-Rex outmaneuvers him, moving onto Triceratops' six and giving him one bite to the rump, shattering the hip bone and separating muscle from it. Triceratops stumbles, one of his rear legs useless and tries to turn to the threat. But T-Rex shifts his bite forward and gets the neck. Blood fountains up as he manages to severe just about every major artery in Triceratops's neck and Triceratops bleeds to death under two minutes. T.Rex.

T-REX VS CHILD

Child wets his pants instantly and runs to hide on seeing T-Rex. Luckily for him Compsognathus is annoying T-Rex and T-Rex is more interested in the tiny dinosaur. Because the child runs away, he loses. T-Rex.

T-REX VS COMPSOGNATHUS

Compsognathus bites T-Rex on the leg, but his bite can't even penetrate the skin! T-Rex drops a seventy-kilo chunk of meat he had gotten from the herbivores his defeated earlier and kills the tiny dinosaur instantly in a dull `thunk' of meat hitting meat. T.Rex.

T-REX VS WEAKEST DINOSAUR

T-Rex has already beaten the weakest dinosaur earlier. It is Stegosaurus.

T-Rex VS EUOPLACEPHULAS

T-Rex pins a screaming euoplacephulas who has lost all bladder control under his foot and places his jaw over his victim before pulling away, tearing the body into half. Euoplacephulas NEVER STOOD A CHANCE.

See? It never pays to insult T-Rex fans!

Ostriches do fine with bipedalism and can run very fast. Just because most mammals that happen to be fast runners are quadrupedal doesn't mean a bipedal animal could be equally fast.
from Chandler, age ?, ?, ?, ?; July 1, 2001

"Bipedalism is a very inefficient way to run"

Not exactly true, you just need different leg designs to make it work better. Ostriches have no problem outrunning many quad animals and such. Being a quad gives you added stability but it still mainly the rear legs doing to running in most animals. Being biped gives you fantastic agility and acceleration and certainly served many dinosaurs well. In fact, the usually quad hardosaurs probably reared up on their rear legs to run. Recovery rates (energy recovered after a step) for bipeds is also generally superior to quadiped animals and the secret behind cheetahs can run up to 65+mph in not in its four legs, its in its spine and hot-rodded body design. Bipedism is inferior to none.
