By the most reliable estimates, the Tyrannosaurus' maximum size is 40-43 feet. This is backed up by "Sue", the largest T. Rex known. She is a 40-42.6 foot long individual that died of old age. That being, she was likely at maximum or near maximum size at her time of death. While it is possible that the oldest individuals reached 43-46 feet, common size appears to be smaller. "Stan", the next largest Rex specimen, is 40 feet and also died of old age. "The Devil Rex", one of the largest is only 38 feet and also died of old age. Peck's Rex, a particularly misunderstood (not overrated) individual, is often said to have been 50-60+ feet. It was later discovered that it was a mere 40 feet at most and the larger bones came from a sauropod.
Another misconception is that Tyrannosaurus hunted in packs. There has been no evidence of this, and when people say "3 Tyrannosaurus skeletons were found in the bla bla bla formation", that doesn't mean they were pack hunting, since formations are huge. They are usually found miles apart. Hadrosaurs were their preferred prey and they wouldn't need to form packs to take them. Triceratops were probably taken down by a lone individual somewhat frequently. Their jaws were built for sheering off horns and taking down large prey like hadrosaurs and ceratopsians as quick as possible.
Their teeth were built for pulling off chunks of flesh without falling out, not crushing bone as once thought. Scrapes or bites on bone are now theorized to be accidental. This enabled them to be effective (I know, I know) scavengers. While almost every animal scavenges, Tyrannosaurus appears to be a specialized scavenger. It wasn't built for running and had overall scavenger adaptions. Though many people take the term "scavenger" as an insult, it just makes Tyrannosaurus deadlier and more successful, showing how resourceful it was. The "deadlier" part stems from the fact that rotting flesh would have been stuck in its teeth and given it a septic bite. It also had thicker (not thick in general, just in relative terms) bones than other dinosaurs, somewhat binocular vision, good hearing and a great sense of smell. This allowed it to ambush prey. Here is a scenario:
A T. Rex finishes the meal she found of a half eaten baby Triceratops. Still hungry, she listens and hears a bugle of a Parasaurolophus in the distance. She follows the sound and looks ahead, seeing a large individual carelessly munching grass away from its herd. The Tyrannosaurus crouches in the forest and quietly slinks forwards, soon coming within 50 feet of the herbivore. Suddenly it lifts its head and smells the air but before it can turn and run she dashes out, closing the distance in a few bounds and clamps her jaws on to the Parasaurolophus. It was not angled right and she only managed to catch a small bite on its side before it rejoined its herd. The herd leaves and she follows the scent of blood throughout the night. The beast dies from the sceptic bite and she enjoys her kill.
In the preceding scenario, there's a good chance she would have caught the hadrosaur on her first try, but to show the effects of the septic saliva and sense of smell, I made her miss. Tyrannosaurus is the king of dinosaurs, but not in the way that it could beat any other theropod that it was pitted against. It was the king because it was the original giant carnivore, its discovery coming long before Giganotosaurus, Spinosaurus, Mapusaurus, Carcharodontosaurus and Tyrannotitan, though, ironically, it lived millions of years after the rest of these species went extinct. T. Rex just isn't the biggest or baddest anymore, and if any of these discoveries came before Tyrannosaurus, the roles would be easily reversed. Spinosaurus only gets so much hate because it murdered the dinosaur everyone knew and loved. If the roles were reversed, then Rex would get the same hate.
Is Tyrannosaurus overrated?
In some ways yes, in some ways no.

MemberCompsognathusJun-25-2013 11:44 PMYesssss, it is completely overrated, but there are some things in the favor of T. rex being a predator. Binocular vision means it can gauge depth and a charge would be successful. Powerful bite, it has thick teeth, and a bite to go with it, it can't be a coincidence that it just happens to be on T. rex, a scavenger would have a much weaker jaw and long sharp thin teeth. It is overrated because, just randomly guessing, 70% of the people who know about this dinosaur has it as their favorite. I'm indifferent, and don't particularly like the very popular dinosaurs.

MemberCompsognathusJun-26-2013 12:43 AMHyenas are scavengers and have one of the most powerful bites today. Tyrannosaurus also was a predator, but it likely preferred to ambush its prey, as otherwise it would have to risk running, and a fall would be fatal. I also am pretty indifferent to the most popular dinos, but I like Dilophosaurus. I view it as a giant lion: powerful and built for killing large prey, but not as often as it scavenged. Thanks for reading!

MemberTyrannosaurus RexJun-26-2013 8:54 AMYou bring up some good points. The bite wouldn't have only taken a day to kill the Hadrosaur though. It might have taken a day for it to start feeling the effects, but it would likely survive for a week or so before it is so weak it can't keep up with the herd and gets left behind.
As far as overrated goes, I'm not so sure. 40 feet is a good size. It might not have been able to beat every theropod it was pitted against, but it could beat them more times than not (in my opinion) due to evolutionary advantages.

MemberCompsognathusJun-26-2013 9:25 AMI thought hyenas only had a bite of 900 pounds of pressure, but I don't know how that compares, and most dinosaurs had a much stronger bite than a Hyena.

MemberCompsognathusJun-26-2013 12:54 PMT-Rex was not the biggest carnivore in terms of length but it was in weight, at about 9 tons, Spinosaurus was only at 7.2 tons, Charcaradontosaurus 8 tons, Giganotsaurus was around the same weight as T-Rex but not nearly as powerful, Mapusaurus only got up to 3-3.5 tons, not even close compared to the others mentioned here, and Tyrannotitan weighed in at 4-5 tons.
T-Rex was built for fighting armored prey like Triceratops and Ankylosaurus, that's why it's jaws were so powerful, the biggest bite force it had was 30,000 newtons to 60,000 newtons, enough to crush a car, so I would'nt be surprised if someone told me that the T-Rex would've won if it ever went up against a tank. It is still by far the biggest predatory dinosaur with the most powerful bite.
Also, T-Rex was said to be as smart as a house cat, there's evidence that proves the it took care of it's young during it's hatchling and even juvenille years, so why could'nt they hunt in packs as a family?
No, the reason most people dislike the Spinosaurus in JP3 is because the outcome was bullshit. Spinosaurus was mainly designed for catching fish while T-Rex actually was made for killing dinosaurs. That and it was the movie's way of passing the torch to the Spino as the main big predator in the film.
Hey, it's not some dinosaur's fault (T-Rex, Triceratops, Brontosaurus aka Apatosaurus, etc.) if so many people love them so much. And besides, I'm pretty sure those were the first dinosaurs everyone knew of when they were kids. If it weren't for them then I wouldn't even have gotten into dinosaurs in the first place.
T-Rex is and will always be the king of the dinosaurs.

MemberTyrannosaurus RexJun-26-2013 2:49 PMT-Rex vs a tank and winning would be far-fetched. Otherwise, well said.

MemberCompsognathusJun-26-2013 2:57 PMPerhaps Tyrannosaurus is overrated a little bit, but then again, perhaps it deserves it's reputation. No Tyrannosaurus was not the longest carnivore, Spino has that title with a length of 56 ft or so. But I think it got bigger than 40 ft. Tyrannosaurus probably averaged 40-43 ft, but maxed out at 46-50. As far as weight goes, that's were T-rex takes the gold. On the average, it probably weighed 8 tons, but was quite capable of reaching 9 or more. You can read about that in my post about T-rex being larger than originally thought. Anyways, t-rex90 is right. Spino probably maxed out at 7 tons. Giga was around 8, Carchar was in the 6 ton range, Mapu was smaller than most think at around 3.5-4 tons, and TyrannoT was about 5. Tarbosaurus had a weight comparable to TyrannoT or Carchar. T-rex certainly had the largest bite force. Minimally T-rex had a bite force of about 6,800 lbs and had a max bite force of 18,000 pounds. They do have a site in Montana that has a group of Tyrannosaurus' of different sizes and ages together. I do mean together, not within 10 miles of each other or something. Other large carnivores like Yutyrannus, Albertosaurus, Daspletosaurus, Allosaurus, and numerous carcharodontosaurs have been found together as well. Small predators also hunted and lived in groups. T-rex almost certainly did the same. T-rex may be a little overrated, but I think he deserves that reputation. They don't call him the king for nothing.

MemberCompsognathusJun-26-2013 4:10 PMI'm sorry, but I have never heard of Tyrannosaurus' teeth being used to tear flesh and not crush bone. Triceratops and many hadrosaur bones have been found with T-rex bite marks. If it was simply trying to rip off flesh, then why are there so many bite marks? They did not happen by accident. Tyrannosaurus used a combination of it's giant thick teeth and the largest bite force of any land animal to crush bone.

Allosaurs teeth. These represent the standard theropod tooth design which was meant for tearing flesh.

Tyrannosaurus teeth. Here we have a tooth design that is not the usual steak-knife shape. Now you're looking at a railroad spike. Perfect for biting and crushing bones.

MemberCompsognathusJun-26-2013 5:19 PMThanks guys and yes MrHappy, I know it does sound far fetched with T-Rex beating a tank but maybe it could bite and bend the canon preventing it to fire it's missils or grenades at it, and although T-Rex was not the fastest carnivore, I'm sure it was defintley more faster and agile than a tank, it could jump on it and take it from there heheh.
And I agree with everything you say as well Rex Fan. You know, I was actually waiting for someone to make a topic like this but as you said, it deserves it's reputation as "The King" and it is why it is one of my favorite (as well as many others) favorite dinosaurs.

MemberCompsognathusJun-26-2013 5:21 PMI promise you that if those teeth were to come in contact with flesh, it would definitely tear that flesh.
Rex Fan 684
MemberCompsognathusJun-26-2013 7:19 PMOf course it would tear flesh. But they also broke bone. That was what they were mainly used for. They could pierce through flesh, they could shatter bone, and they were anchored by extremely deep roots.

MemberTyrannosaurus RexJun-26-2013 9:15 PMI personally don't see Spino getting past 11 tons. I could see Rex getting to 8 tons easily, 9 tons if it lived really long, and 10 tons is a bit far fetched in my opinion.

MemberAllosaurusJan-07-2014 9:12 AMI'm against the fact of a Tyrannosaurus' septic bite. Sure, the bite of it was really strong and infectious, but some people take the septic bite theory as far as the dinosaur being poisonus. The "poison" was, as you said, rotting flesh. Who's to say Spinosaurus or Giganotosaurus didn't have this bite? They probably scavenged a lot also. Also, do what I do. Stop saying it's the king of all dinosaurs. Just, please, call it Tyrannosaurus. (P.S. Tyrannosaurus wasn't the king of all dinosaurs. Dinosaurs didn't have a monarchy system) I agree. Tyrannosaurus is overrated, but Spinosaurus is underrated if you ask me. Other large carnivores deserve some sort of fame or popularity outside of paleontonogy.

MemberTyrannosaurus RexJan-08-2014 5:29 PMIt's name literally means "Tyrant Lizard KING," so we call it the King because that's what it translates to. IF Spinosaurus was "Spinosaurus Rex," and translated to "Spine Lizard KING," we would likely refer to Spino as "The King." Because Rex translates to King, and Tyrannosaurus has Rex at the end, we call it "The King."

MemberAllosaurusJun-17-2017 7:22 PMT.rex is not overrated. Look everywhere in videos where it is pitted against other dinosaurs. In Fred the Dinosaurman's claymation between Giganotosaurus carolinii and Tyrannosaurus rex, Giga was deemed the winner because more people voted for it. Honestly, it's kinda sad. Nobody has any respect anymore for the Tyrant King...
