Saber-tooth vs. Megaraptor

To the contray, I think that despite being smaller, the Saber-tooth will win. Well, he certainly has the advantages in speed and agility (being a cat) over Megaraptor and will probally go straight for the neck while Megaraptor tries to slash him to death. A single neck bite on a Megaraptor from a Saber-tooth is almost certainly fatal. 14 inch claws are good for prey that is afraid of you and have the surface area of a barn to hit, but against a fast, manuverable target, their effectiveness is certainly reduced. A jaw would be better in this case and who bites the best in this match? Saber-tooth!

T.Rex vs. Indricotherium

Woah! I don't think T.Rex would want to mess with Indricotherium, that think is like a horse the size of a small sauropod, and a mule-kick from a leg that size would certainly break a few ribs or seriously injure a T.Rex. But of course, if T.Rex managed to get Indricotherium by the neck, the 3-ton force at the tip of each of the teeth would rapidly slice through the mammamilian skin and sever many vital blood vessels, and that would be quite the end of Indricotherium. I figured T.Rex wouldn't be boneheaded enough to apprach Indricotherium directly behind, and would be aggressive and agile enough to avoid attacks as it was used to attacking prey animals like Triceratps, so T.Rex might have the advantage if it employed the neck bite and the hit and run tatics instead of the boneheaded let's-go-in-close and fight a gigantic animal that weights two mammoths! In that case, T.Rex has a very good chance of winning as these tatics allows him to avoid injury and inflict massive damage at the same time. And I think hit and run would be good for Indricotherium, and T.Rex would have used that if he didn't know the neck bite or the situtation prevented him from doing that. I think in this case T.Rex would win.

SPERM WHALE v.s LIOPLEURODON

Hmm tough one... but I'll follow Brad, the Sperm Whale is not a really of great hunter of large animals save giant squid. Liopleurodon would have some troble trying to breach the Sperm whale's skin, but then again, I doubt the Sperm whale is doing much against Liopleurodon. Of course, if this confrontation took place in the Alantic ocean...it might be a different story all together. As Sperm whales are perfectly fine in cold water.

SABER-TOOTHED TIGER V/S MEGARAPTOR
_Megaraptor_. Those 14-inch claws could really cause some hurting!

IDRICOTHERIUM v/S TRYRANOSAURS
_Indricotherium_ was considerably heavier (if the ZoomDinosaurs Dino Dictionary is a reliable source). It probably crush the rex's legs, but not before the rex caused some damage... this is hard! I'll guess _Indricotherium_.

SPERM WHALE v/s LIOPLEURODON
I really have no idea what whales do for defense- do they ever fight anything? I know pliosaurs can bite to do some damage, so I'll bet on the _Liopleurodon_. But then again, sperm whales have teeth too.... They fight gigantic squids, don't they? Uh, still _Liopleurodon_. Gotta go with the prehistoric reptile.

SPERM WHALE v/s LIOPLEURODON
from MANUEL L., age 20, IQUIQUE, IQUIQUE, CHILE; May 31, 2001

"I just wanted to add that Velociraptor or the Deinonychus was generally close to 6 feet long and weighed approximately 130 pounds. That is until the Utahraptor was dicovered."

The discovery of a new species does not change the measurements of previously known species (How could it?). Velociraptor wasn't anywhere near 130 pounds, though. More like 30 pounds.

"The Utahraptor was twice as big and weighed in about 500 to 1000 pounds. It truly was about the size of the `Raptors in Jurassic Park by Steven Spielberg. Read the book ``Raptor Red`` by acclaimed paleo
scientist Robert T. Baker. He is the one that Spielberg consulted with in the making of Jurassic Park."

I heard that Bakker wasn't an official consultant, but rather communicated informally with the dinosaur makers. I think Seilberg's major consultant was Horner.

"He also had a cameo appearance in Jurassic Park ``The Lost World`` where a snake goes down his shirt and he is eaten bt T-Rex."

That wasn't Bakker, it was Thomas Duffy. Duffy's character, Dr. Burke, may have been based on Bakker.

"``Raptor Red`` is an excellent book about the giant Utahraptors and it tells the story of Utahraptors existance from the point of view of the `Raptor"

Eh, it was okay. Maybe a little outdated.

I seriously doubt that Megaraptor was 20 feet tall, as its length estimates are only around 20-25 feet. Even Tyrannosaurus wasn't 20 feet when standing naturally, more like 12-15 feet.

Let's be nicer to Cameron. So what if he has different views on Tyrannosaurus rex?

Tyrannosaurus was just an animal, and its dead. Its not your friend, your king, or your god. We do not know if it could kill Triceratops, or if it scavenged a lot, or if it ate lawyers off toilets (although we can probably rule out that last one). Why must we be so defensive of it, trying to make it the most perfect killing machine that we want it to be? Tyrannosaur behavior is nothing to fight about.
from Brad, age 14, Woodville, ON, Canada; May 28, 2001

I'm not sure how a blue whale and a sauropod would fight. The blue whale can't go on land, and the sauropod can't go in the ocean. This would be completely dependent on environmental conditions- and even so, the loser would be killed by the environment and not by its opponent!

Liopleurodon. I hate Megalodon.

I'd say Tyrannosaurus would beat Megaraptor. Tyrannosaurus is a pretty powerful theropod, and it was much bigger than Megaraptor. There is no proof saying that Megaraptor is a dromaeosaur as many people beleive, and not an avialian or something else.

from manuel l., age 20, iquique, iquique, chile; May 28, 2001

Actually Brad, any dinosaur has to be quite dead for T.Rex to eat it...for any dinosaur for that matter...it just dosen't prove anything. But a large number of bites to a single area of a body points towards the idea that the animal was brought down and killed. And some fossils with T.Rex bite marks do show this feature, a large concentration of T.Rex bites to a single area, and then bites all over the fossil tend to point towards T.Rex bringing down the animal and later feeding on it.
from Leonard, age 13, ?, ?, ?; May 27, 2001

"If a T.Rex got into a fight with a pack of raptors here 's what would
happen:T.Rex claws and bites and kills half the pack..."
-Cameron

"T.Rex couldn't kill anything!"
-Cameron

Well Cameron, which is it? Actually, we have no evidence of Tyrannosaurus killing anything. Healed bite marks indicte that Tyrannosaurus hunted, but that it didn't kill that particular animal. Eaten bone indicates that Tyrannosaurus was chewing a dead dinosaur, but we cannot prove that the Tyrannosaurus killed it. But even if Tyrannosaurus couldn't kill large ceratopsians or hadrosaurs, I have a hard time beleiving that it couldn't kill animals like Leptoceratops and Thescelosaurus.

from Natalie S, age 10, Prince George, BC, Canada; May 15, 2001

Seeing people actually go through the trouble of responding to such a one-sided fight between Tyrannosaurus rex and Deinonychus antirrhopus, I thought I might add in my own pound of salt's worth to this argument:

I figure it comes down to two things: surface area of the Tyrannosaurus' mouth (as opposed to the s.a. of the individual Deinonychus' mouth) and gastrointestinal fortitude.

If a Tyrannosaurus has a mouth that is, oh, say five feet long and two feet wide(I am doing the math slowly for you science boys and rounding to the nearest foot, of course), that means that the Tyrannosaurus has 10 square feet of mouth surface. I'd say that with that kind of coverage, every time the Tyrannosaurus makes contact with a small Deinonychus body or head (as opposed to grabbing a leg), he inflicts a mortal injury, if not an immediately killing blow. Meanwhile, your average chicken-in-dinosaur clothing has about, oh, say 0.5 square inches of mouth area, which means it can't even encompass one bulging Tyrannosaurus muscle in its wee yapper. So the Deinonychus are just barely breaking the skin, but the Tyrannosaurus just has to stay angry enough to take about twelve bites--okay, allow about five or six extra bites for the Deinonychus as he only gets by a leg the first time. He'll have to go back and take a second chomp once the maimed Deinonychus are down and helpless. Well, some people would argue that the Deinonychus coudl use their sickle claws, but I doubt a gash is anywhere near as deadly as a Tyrannosaur bite. Tyrannosaurus certainly packs more firepower into a bite from his jaws than a pack of six to twelve raptors.

Will the chicken-like Deinonychus take this lying down? Only if the Tyrannosaurus just grabs their legs on the first bite, allowing them to survive the first Tyrannosaur attack. But they are better off attacking a carcass that rarely fights back instead of an angry big Tyrannosaur. But everyone knows that Raptors in general (including Deinonychus) have tender stomachs and get sick at the drop of a hat. Remember the fossils of Deinonychus found around a Tendontosaurus carcass? Apparently the carcass went bad and they died from food poisioning. The Deinonychus will just get sick all over the carpet, thereby inducing all its pack buddies to begin woofing (pardon the pun) all over the carpet too. Soon the Tyrannosaurus will have Deinonychus *and* dessert.....

from ?, age ?, ?, ?, ?; May 13, 2001

Hello Garrett! If a Tyrannosaurus and Deinonychus fought, the T-Rex is more likely to tear apart the Deinonychus from limb to limb. The T-Rex is a lot bigger than the Deinonychus and its teeth are much stronger.....BUT, fossorial remnants suggest that Deinonychus hunted in packs. If that were the case a group of Deinonychus might have attacked a single T-Rex and could have finished it off.

the reason i use this tounge-twisting name is because i think it's counted as the "better" name for Troodon. if Kentrosaurus and Allosaurus got in a fight:

Ol Allosaurus also known as Big Al by his fans darts in and takes a bite. Then he steps back and wait for Kentrosaurus to get weaker. A minute later Kentrosaurus is now laying dead at the feet of Allosaurus. Big Al won his victory once again!

or:

Kentrosaurus lashes his tail at Allosaurus and smacked thoe spikes right in Big Al's stomach! Soon all of Allosaurus's insides spill out all over the ground. Now an Another victory for Kentrosaurus the Spike-Plated Stegosaur!

Please Stenonychosaurus (phew!), why do you want to use such a tongue twisting name (my tongue is as spiral as the Whirl-Pool Galaxy after trying to pronounce the dino names). That pea brain (Stegosaurus) might have used its spikes to absorb heat during the day and save it for night. But some dino experts feel that Dimetrodon used its sail to attract a mate. Same can be true for a stegosaurus. Imagine a Stegosaurus without those spikes. It might not have found any other method of mating, as it is such a brainless git.
