Paleontology News: The Size Limit of Tyrannosaurs
Vložit
- čas přidán 1. 02. 2017
- Ranging in size from species like Lythronax to titans like T.rex, tyrannosaurs dominate popular dinosaur culture. Their fossils have been known for over a hundred years, and since their discovery tyrannosaurs have only grown in popularity (especially T.rex, which despite recent trends is still more popular than Spinosaurus). The tyrant lizards are famous for their size and power, but there are a few misconceptions that can be cleared up with the use of science.

@Gabriel 1234 Yeeep, me too.
Yeah same lol

At 3:04 I noticed that the teeth on Stan and Sue were noticeably different because Sue's teeth seem a bit more neatly placed while Stans looks like a normal tyrannosaurus. On Sue, right above the nasal cavities there seems to be a big 'arch' on a t -rex in that spot, Sue's 'arch is much more flat. Sue might be a Larger than average t-rex but possibly a new species of tyrannosaurids.
You see, the problem is that you're taking the "Possible undiscovered larger individuals" reasoning and only applying it to T. rex when really it applies to all giant theropods in general, especially taking specimen sampling into consideration. Why is no one arguing for the possible existence of a 14 meter long Acrocanthosaurus or a 20 meter long Spinosaurus if we're really going to start speculating about how much bigger a species can get (than what is currently known)? If it's plausible for a T. rex to be 20% larger than the average size of the 50 specimens we currently have, then following that statistic and reasoning, it should be equally plausible for a Giganotosaurus to exist that is 20% larger than the current only 2 specimens we have. Same goes for Carcharodontosaurus for which we have only 2 specimens, and so on and so forth for every theropod dinosaur in general.
+Luigi Gaskell I completely agree that it's possible for other theropods to be larger by similar margins, and I don't believe I discounted that in the video. However, it's more practical to spread the idea by using a video on the subject of tyrannosaurs, since they are the most popular (and therefore searched for) theropod clade. I appreciate your feedback.
The Vividen True, you don't discount that in the video. But people will watch this and think it only applies to T. rex given lack of specification. Though of course, it's for the the most part their fault for being bias and not having an attention span.
+Luigi Gaskell Perhaps if I made a 20-second version of the video then viewers would be able to pay attention. Or a vine. Lol.

A Tyrannosaur that large would be a very rare specimen. Like above average crocodiles or sharks are incredibly hard to find
Even nature wants this thing to be more monstrous.
+TyrannosaurusLives And we're all very happy about it. Thanks, nature.
TheVividen Gee, I posted this to G+ someone did not like it.

Ya know, while people are certainly having valid and logical points here, I think the fact that it's tyrannosaurus experts who claim such animals could exist gives at least a little bit more weight to the claim, but that's just me
TyrannosaurusLives ppl
TyrannosaurusLives ppl
I will already say to all Spino fans that Spino never reached 60 ft and 20 tons
This argument is simply based upon the fact that there is practically zero chance of us finding the real large specimens of the species due to the rarity of skeletons fossilizing at all. Is it a good argument? Yeah, but we can't really determine how big they actually get from just this. Tyrannosaurus is actually one of the worse examples of this. Why? Because we have A LOT of adult Tyrannosaurus specimens and Sue is still the largest (I don't believe "Trix" has been officially measured yet) surpassing average specimen size (around 11.8 meters) by a decent margin. And, with the ontogenetic changes that Tyrannosaurus goes through, we know it can not grow too large as it will just fall on its head. Other giants like the carcharodontosaurids are much better examples of this because we don't know their average size all too well because we have so few specimens that we can estimate a total size from and because they are more lightly built than the Tyrannosaurus and don't undertake very similar ontogenetic changes, they are probably capable of growing to larger sizes.
I thought UCMP 137538 was the largest.
Mesozoic Studios UCMP 137538 is only an isolated partial toe bone that is around the same length to Sue's but just a couple millimeters wider. There are no sources in scientific literature saying it was significantly larger than Sue's corresponding phalanx. Not only that, it had visible osteopathologies which could indicate that the toe was swollen and therefore disproportionate. It probably belonged to an average sized individual.
Ok so your argeument if a t rex gets bigger than Sue it will fall on its head is very incorect because the tail of the dinosaur will grow along with the rest of the body the head at the same time wont grow large enough for it to be too heavy we now know that Trix is begger than Sue The Vividen himself showed how Trix is bigger than Sue in his videos.And you saying carcharodontosaurus being a better example i dont belive it because carch and giga hunted sauropods they both needed to be fast and if it got much bigger it would be harder for it to hunt a souropod while t rex growing even more would help it fight a triceretops or an anatosaur.Spinosaurus is also very likely to be even bigger because of its aquatic lifestyle since aquatic creatures tend to be bigger.The reason the video was about t rex was because we know the most about t rex and about its habbitat and with that much information the actual experts can come to conclusions like this because you were forgeting that actual tyranosaur experts said that t rex probably grew bigger than Sue.
maksim mihailov on how T. rex not falling on it's head as it grew, read Hutchinson et al. 2011 on their ontogenetic discussion.
So I should trust the size estimate made by a person on the internet who is neither a professional paleontologist or has access to the actual skeletal remains of "Trix"? Yeah, no thanks.
Your argument that speed was very important for carcharodontosaurs doesn't really make sense when you consider the fact that allosauroids were not very cursorial animals. If they needed speed for hunting so much, you would expect them to be fast or evolve to be quicker but instead they grew larger. The late tyrannosaurs show more evidence for being cursorial than allosauroids and Tyrannosaurus itself would most likely be able to outrun Allosaurus or Giganotosaurus.
The reason the video was about T. rex is because it grabs more attention.
I am not doubting Tyrannosaurus growing larger than the current fossil remains, it would be very silly to say that "Sue" was the largest Tyrannosaurus ever to have lived. But this argument should be applied to every extinct animal only known by fossilized remains. And by watching this video, there will certainly be some people that interpret this as Tyrannosaurus being far larger than any other theropod when in reality, using this argument scales up every other non avian theropod too and not just Tyrannosaurus and that in fact, Tyrannosaurus itself is not a very good example on this argument and that other theropods should be scaled up even more.
In my ipinion it is almost stupid to think giga and carch could not grow larger but by what we currently know about them we cant be as shure.And this vidio was about t rex because as you said it grabs more attention but its also because we know more about t rex so that we can come to a conclusion easier than lets say giga or carch.Right now with the fossils that we had we have evidence of t rex growing bigger than the largest giga for now im sure if more people try to find giga remains we will find a even bigger giga but from what we know now t rex can grow up to be the second largest carnivore.And listen when you aply the skuare cube law equasion you get trixes size and then you see that it is bigger than sue ive done the calculation my self the vividen did it and i got the same results.So with that you cant say ''Trix"like it doesnt exist or that it isnt that size
The fascinating thing is that the more fossil evidence there is, the bigger T. rex gets...the sky is the limit!
+Aquarimax With the way the fossils are going, even the sky might be too small.
The Vividen lol
Aquarimax the largest trex found is bigger than giga and carchara
Remember the end of the video
Reform 2018 Sue is the bigget "complete" T rex found, there´s around 4,5 specimens wich has been found that have bigger skulls than Sue, and of course both UCMP
This video is really accurate for me and really good, yet you only have almost a thousand subs. You deserve more dude! :D

I personally don't mind him applying the size estimate s to t.rex,when they took the fragmentary bones of spino and giga and said they were 50ft long and 43ft long,no one complained ,but when they did the same with t.rex with the fragmentary bones found from other specimens ,everyone was trying to shut it down ,despite the evidence being more reliable ,because 1. We've studied t.rex more 2. We have numerous t.rex skeleton s to compare them to ,if we can give almost theroized estimate s on all these other large therapods then why not t.rex????
i love how People like the more *famouse* dinosaurs and dont care about other dinosaurs when Spinosaurus came everyone tried to make theories that will make Spinosaurus as weak and as small as possible and t Rex is 7 - 8 tonnes do you know how big that is and yet you want to make it godzilla....
@@smartboi9655 Scotty the T. Rex is estimated to have weighed in at 10 tons, and quite possibly more. Why do you have a problem with the T. Rex being the largest theropod?
@@classicgalactica5879 Paleontologists dont know that .
T rex average size is 39ft 11.7 to 40ft 12m hip height 12ft 3.7m skull lenght average 4.8ft 147cm .
Average weight 7000 to 7500kg.
The 50ft spinossaurus was a subadult he would probably grow larger .
T rex is like a pitbull the supreme predator the most advanced theropod ho cares my dick is 6 inches i wish it was 10 but it works fine ...
Wat if we find a Tarbossaurus that is 12.9 meters long and 3.9 meters at the hipp with a 5.1ft long skull 154.9cm skull.
And 500kg more then Skotty you guys would be mad?
You guys are Autistic af 😂😂😂
@@classicgalactica5879silly fights between fans between fans of Spino and T Rex. 😂
T-Rex being the superstar of the Dino world the only way people are going to take notice of new predator finds in their minds will jump the gun and make false claims it's larger and bigger then T-Rex so they can steal the spot light until the real truth of the matter comes out. A common ploy and wishful thinking on their part. As big of a superstar T-Rex is he has as much haters that want him overthrown as much as he has a fan base. So when comes to being bigger and larger the others have been found to lack in taking the crown. T-Rex for example has been blamed for sucking up all the oxygen out of the JP and JW movies but the real guilty party is Raptors chasing people nonstop all the time and ends up making the movies boring. T-Rex has been king since 1903 and with the other guys lacking is driving the haters nuts but sorry to tell them it is what it is. T-Rex rules and it don't look like he is going to step down anytime soon.
Most up to dat data - T-Rex still the King and more awesome than originally thought.
T-Rex - Typically 12-13m long, 7-9 tonnes, At limits Up to 15m long, 12-15 tonnes weight
Spino - Long at 15m but gracile and "only" 6-7 tonnes.
Giganotosaurus slightly smaller than originally predicted and not as robust or heavy as T-Rex.
new Chinese Tyranus similar to T-Rex, data pending
So your telling me that the trex is heavier than both the giga and the spino!?Wow trex ain’t nobodys fool
my left ear enjoyed this
Starry Nights mines did not 😔
So if Trex could be over 45ft then who is to say that Gig and Spino didn't reach larger sizes. If a 45ft plus rex is reasonable then why not a 55ft plus spino? Spino might be the lighter one though.
Size needs support as more food would be required and the animal may not be able to perform its normal functions if it grew too big. Most likely Spinosaurus has the largest size possible and could not grow any larger or it could not function.
the oldest Spinosaurus fossil found is a Sub adult and its 50 lenght and 7-9 tonnes Spinosaurus isnt small...
Epic Destructor and your evidence is ???
No, the oldest spinosaurus fossil comes from a fully grown adult that is around 50-55 feet long. Sub adults were around 35 feet.
We know now spinosaurus lived most of its life in water though so it might not have had the size restrictions a strictly land animal would
Whoa, that's big! XD Nice video, Isaac!
+Ender Luigi Nightmare Thanks!
Its fake a trex with the mass of only 8 tons reaching 50 feet is just dumb
i love having audio only come from the left side of headphones
Hey does anyone know the skull measurements of Trix? I've looked all over and can't seem to the numbers on this thing's head
Does make one wonder about the other big theropods as well. Given relative lack of specimens, the main reason things like Giganotosaurus c. keep having massive fluctuation in mass estimates if due to us not having a good enough same size to get an idea of average or maximum sizes.
My left ear is uncomfortable
VERY GOOD VIDEO!!!
here are some scientific facts about Rex, Spino and Giga.
Trex:
Size: 12,8m (Sue) - 16,5m (UCMP 137538) UCMP 118742 and Tufts-Love being nearly Sue's size at age 16 and 15 respectively is absolutely massive. (Tufts-Love was 12 meters at 15, UCMP was 11.9 meters at 16) Tufts-Love is to have grown up into a 16-meter (53-foot), 17-ton monster, considering it's more than 20% complete. Estimates (we can accurately pinpoint Tufts-Love's adult size for its complete skull, but not for UCMP 118742 as it's less than 10% complete) for the less complete UCMP 118742 range from 13.2 meters (44-foot) and 15.1 meters (50-foot) for adult lengths.
Weight: 8.500kg - 15.000kg (UCMP 137538)
Biteforce: 18,000 pounds
Tooth: teeth were serrated, conical up to 30cm long, and were constantly being replaced (all 2 years).
Intelligence: The brain of a T-rex weighed about 1kg and was twice the size of the brain of the giga. the trex was one of the most intelligent dinosaurs that ever lived.
Vison: with eyes directed forward like a falcon, for better depth perception the trex had a far better view than other Predators
Links: dragons-and-dinosaurs-free-historical-resources.fandom.com/wiki/T_-_rex_size
Giga:
Size: 13,2m
Weight: 7.500kg - 8.000kg
Biteforce: 6,000 pounds
Tooth: teeth were 20cm long, sharp, short and narrow with jagged edges
Intelligence: The brain of a giga weighed only about 0,5kg and was not very intelligent
Vison: narrow binocular overlap and a restricted binocular view
Links: theropods.fandom.com/wiki/Giganotosaurus_carolinii
Spino:
Size: 14-16m
Weight: 6.000kg - 8.000kg
Biteforce: 4,200 pounds
Tooth: 14cm similar to today's crocodiles
Intelligence: was an “advanced theropod”, making it one of the more intelligent dinosaurs. Its EQ (Encephalization Quotient), which measures brain size relative to body weight, proved that
Vison: if they resemble that of a crocodile then very well
Links:
then again, the same goes for giganotosaurus and other therapods of the cretaceous, because the exact statements you make can be used both ways, and unlike the rex, the other apex's of the cretaceous have a much higher chance to be larger than a tyrannosaurus than we depict, because of the fact that the rex has had many more specimens uncovered than most therapods, and there for, we can easily average out the size of most tyrannosaurus rex's. a easy fix would be to replace the "tyrannosaurus" in this videos tittle, with "therapods" or better yet, "dinosaurs" in general, and use the same arguments as you are, but with more than just a fan favorite dinosaur, and more facts on other dinosaurs. my point is, stop putting tyrannosaurus into the spot light, this question goes for any dinosaur.
He put tyrannosaurs in the title to atrract more viewers as they are the most popular

@mino323 Roblox 100ft rex
We go with facts and the facts are made public that a T-rex on average was bulkier than other therapods. And we also won't deny if any of those are proved larger than T-rex like how Spino was bigger and badder than T-rex till 2014 discovery and even I believed it before the paleontologists said otherwise.
The Hammond meme got me
I agree with this. There is no way in hell that a T. Rex built like a tank is not the heaviest theropod known. The greater length of Giga and Charcha don't mean much because they have a leaner build. That's even truer with the very sleek-bodied Spinosaurus even if it's over 50 feet long.
Paolo Pasaol No.
Deform 2018 What do you mean by no?
Paolo Pasaol What do you think? Tyrannosaurus could reach such a size?
Deform 2018 It's not that I think it's super sized. I believe a T. Rex can achieve a length of over 43 feet and a weight of 8 tons (9 tons for an absolutely massive one). What I was trying to imply was that even 46 feet of Giga and 50 plus feet of Spino I don't think can reach more than 7 tons due to their sleeker build (the Spino I actually guesstimate at 6 tons max)
Paolo Pasaol Spinosaurus build varies from what GDI you use. Also take into account the thick heavy skin, wether the spines were a ridge or skin tight sail, ETC.
Fascinating video, I wish my right ear could've enjoyed it.
Awful lot of people trying to fight the proof to this video when you never know that other bigger (Longer or taller, really) carnivores could already be at their maximum size without deep research.
Can't believe this video came out 6 years ago. Back then, Scotty hadn't been described yet, and David Hone hadn't published the 70% larger T-Rex study. Do you wanna consider doing an updated video on this?
I'll probably cover it in the Bertha analysis. Good idea!
IT'S OVER 9000!!!!!!!!!
Size limit on spinosaurus
Limit is unknown, but upper estimate appears to be about 45ish feet now that the largest snout was reassigned to Sigilmassasaurus.
100ft most likely
@@archdh4767 Wrong. You're thinking too small. 10,000 feet is more likely.
@@DarthPyrusTheVirus true, probably 100,000 tons aswell
@@DarthPyrusTheVirus MSNM-V-4047 is just as likely to be spinosaurus. There has been a lot of debate on these fossils ranging from the only spinosaurus was the original to all these spinosaur fossils are the same animal.
Nice info but the sound is panned to only 1 speaker
The thumbnail rex is the old rex from The Isle lol
How tall is Tyrannosaur Rex 15-20ft tall? How long can they reach 40-42ft long if more any bones founded to proven that truev?
when you have only found a handful of examples of any creature, as with trex, its highly improbable you have found one of maximum size, so its almost certain trex grew bigger than the found examples. when we find a hundred, we can be sure on maximum. considering elephant herds, most visible individuals are the females and young which are about a third smaller than the massive mature bull elephants. so in future, the average ones and youngsters are much more likely to be found in the fossil record.
but probability also works the other way too. its pretty unlikely we have found particularly small t rex either. all in all, adding about 20% to biggest found t rex is not unreasonable. anything much more is increasingly unlikely.
andy765gtr
Bullshit we have found MANY T-Rex specimens and know their approximate medium and maximum size
This is scary to know some bird dated in the late Cretaceous period was this large
Well, he was my favorite since I was 4 years old. And yes, it was before Jurassic Park came out.

So......you're telling me that T-Rex really had a bodylength of 50 feet? Holy s**t. About the same size as a Spino. Man this is crazy.
+SpinoDragon Productions Most Tyrannosaurus wouldn't be that big, but yes. According to the experts on the subject, T.rex could reach a length similar to Spinosaurus with a much greater mass.
SpinoDragon Productions yes, but using this argument, 18 meter Spinosaurus are probably out there too.
Pandega Wikantyasa and don't forget giganotosaurus since it seems the average is larger than the average t.rex who knows how big that thing is.
no lol
+SpinoDragon Productions the t-rex is 52ft long but maybe there is more bigger specimens than that.
Since the normal t rex size is estimated to be 40 feet long and the normal spinosaurus size is estimated to be 55 feet... how big could a spinosaurus get??? Hope in the near future that we will find more spinosaurus bones. since we have found so little spinosaurus bone and allready estimated that it can reach 55 feet what is its final form? To me it makes sense for a 65 feet spinosaurus because it got endless supplies of food in the rivers while the t rex had to fight for it and sometimes had a really hard time getting food. And remember eat big to get big.
My left ear enjoyed this video
Yo dawg, I heard you don't like sources, so we got rid of all the sources in the description
Spinosaurus:
- OLD Estimates published in 2005, 2007, and 2008 suggested that it was between 12.6-18 metres (41-59 ft) in length and 7 to 20.9 tonnes (7.7 to 23.0 short tons) in weight.[2][3][4]
- NEW estimates published in 2014 and 2018 based on a more complete specimen, supported the earlier research, finding that Spinosaurus could reach lengths of 15-16 m (49-52 ft).[5][6][7] The latest estimates suggest a weight of 6.4-7.5 tonnes (7.1-8.3 short tons).[6][7]
Tyrannosaur Rex:
Tyrannosaurus rex was one of the largest land carnivores of all time. One of the largest and the most complete specimen, nicknamed Sue(FMNH PR2081), is located at the Field Museum of Natural History. Sue measured 12.8 meters (42 ft) long,[2][3] was 3.66 meters (12 ft) tall at the hips,[4] and according to the most recent studies, using a variety of techniques, estimated to have weighed between 8.4 metric tons (9.3 short tons) to 14 metric tons (15.4 short tons).[3][5] A specimen nicknamed Scotty (RSM P2523.8), located at the Royal Saskatchewan Museum, is reported to measure 13 m (43 ft) in length.
Sorry guys Spinosaurus is way smaller that we all think and t-rex way bigger.

What spinos?
Remember...There's always be bigger rex XD beside Sue
1:54 ITS OVER 9000 !?
One thing i feel that many paleontologists fail to consider is that many of these dinosaurs that they find are so similar that they might actually be the same thing. For example the only major difference between Utahraptor, Dakotaraptor, and Deinonychus is just their size. They're even from the same region! Whats to say a Utahraptor is just a larger Deinonychus?
it exist a found of skull from a very big Tyrannosaurus and this one have the name Tyrannosaurus Imperator
Average t rex size is .
Length 39ft 11.7meters long to 40ft 12meters long.
Height at the hip average 12ft 3.7meters .
Average skull size 4.8ft 147cm.
This made me remember the most embarrassing thing lol
Scotty enter the chat!
Didn’t the spino have a weight between 9-20 tons ?
noooo... thats well outdated and should just be forgotten about, if it in fact was large it wouldn't be able to function normally, 9 tonnes is already pushing it. spinosaurus was lightly build, altough very long it was very elongated, its hind limbs where smaller, and had a very lightly build skull. this made up for an animal which weighs much less then you would expect of a 50 ft long predator, newer estimations put it around 3 to 7 tonnes
How big spinosaurus would get????
Cardinal Jw Animator 1 the tippy top Highest estimates are 18 to 19 meters, but that is just as ridiculous as the the 15 meter Rex.

That would be cool.
@@cardinaljwfkstudios6583 oh shut up so you say that trex is 20 metres long? Stupid
@@GotamaFusion What? I've said nothing like that. Looks like you're stupid.
I think that just with humans having some few extremely large individuals, it could have been the same with those dinosaurus, but i don't think that a 20 meter tyrannosaurus ever walked the earth, sue's bones were 100% grown meaning that she was an adult and it's estimated size was around 12.8 meters, also females were larger than males.
yes some weighed more than 10 tons
What if they where like crocodiles, they keep going until something kills them
My right ear feels very lonely.
T rex is a more common fossil, while spinosaurus is a rare fossil, spinosaurus could have possibly gotten bigger
As the old saying says, you never catch the biggest fish in the pond.
NOOOOOOOOOOOOOO IN GAMES ITS TOO OP
Giganotosaurus Carolinii lol
This is kind of ridiculous. Yes, I agree T-rex was heavier than both Spinosaurus and giganotasaurus but heavier than giganotasaurus by only 800 kilograms. I don't think a T-rex would reach 10 tonnes or 50 feet in length.
Problems with giant tyrannosaurus is that it's impractical it becomes slower and less agile so it's prey would be able to escape easily
True, but what if T.Rex was a scavenger?
I wonder if a 50 bmg would drop it ? Maybe we'd have to go T Rex hunting with a tank 👀. I understand Roland s obsession.
Thanks, random guy in the back of my left ear, now get out of my house, please.
What about "Scotty", I've seen many videos that Scotty is bigger and heavier than Sue. Is this proven to be true ? Thanks for the cool video
This video was made 4 years ago, and yes, Scotty is only slightly longer and a little bit larger than Sue.
My right ear feels lonely
Was T-rex really that heavy? They did have hollow bones like bird!
+The Poke'Saurus Apparently, it was that heavy. It was very solidly built, and many of the pneumatic spaces in its skeleton were filled with muscular tissue.

Sounds realistic!
t-rex wassn't bigger then spinosaurus spinosaurus whas the biggest theropod dinosaur ever and the heaviest at 50ft. and 21 tons

Wait, and the spinosaurus weren't even adult either? Imagine a 69 foot spinosaurus xd
Rip spino
Tyrannosaurus is gigantic!
Compared to you, it's certainly a giant. ;-)
So over 13-16 meters in length and 8-18 tons isn't big enough?
It's extra *THICC.*
1:53 nice "over 9,000" joke.
Perhaps sue is a separate sub species of trex, just like today we have different sub spices of lions in africa, some get to grow bigger than others, I assume the same could be said about t.rex, also there are spinosaurus specimens that were adults and reached only 11M in length, then we have deinosuchus with a max length of 10M long yet it is argued that it may had reach lengths of over 12M based on fragments and still we have bigger fragments of bones bigger than sue's but no one cares to say t.rex could possibly reach lengths of 15M, every other creature gets to have a size range but not t.rex, it was 12M max for ever and ever.
I’m sorry but your argument is notably flawed saying that trex could have grown to 50ft in length, but at the same time can’t the Spinosaurus apply to your argument to? I mean wouldn’t it be an even higher possibility because paleontologist know less information on the spinosaurus than the Rex, making the probability of a larger spinosaurs even more solid then your theory on a 50ft Rex?
Dino ASMR
T Rex was the ultimate killing machine among dinos due to evolution, reach 14-15 mts long is just a plus XD
That's over exaggerated

T.rex is bigger than spinosaurus because spino is a quadruple
Back in the day (70s maybe?, I have a book from the 90s saying 15m) I'm pretty sure that T.rex was estimated around 15-16m at max. Of course these were downsized to prevent speculation but, fragmentary remains of species do suggest massive individuals. Of course this may be disproven, funnily enough only in the less popular dinosaurs, but we have to remember average species. T.rex is often stated as 12 or 13m but the average is about 11. However, rexes could likely get a fair bit larger. This is where the other carnivore's come in. The many Theropods listed as larger than t.rex are done so because one specimen is found to be the size of the bigger t.rexes, yet is likely only the average. T.rex is studied so much more than these carnivores are, and it much more well known than the likes of giganotosaurus or spinosaurus. So there is an overlap. But there were many carnivores which likely surpassed the rex in size on average, despite some rexes being bigger than said average.
Its now comfirmed that the rex is bigger and better than ever
Space Pirate Playz HD No, this is Speculation, not pure fact.
spinosaur is actully 21 tons now 6 and t-rex is 20 so spinosaur would kill it? idk
Greggnah bro
Trex has never reached 20 STOP MAKING UP THINGS YOU TREX FANYYS
@@GotamaFusion so scientists are fanboys? Also how could a Rex be 20 tons it was more likely 9-10 tons and spino 7-10 tons
That's stan
We now know that trex was 15 meters long 6 meters tall and was 10 tonnes making it larger and heavier than the giga, carca and mapusaurus
WTH that's so fake how can a trex possibly surpass 15 metres in length and 6 METRES IN HEIGHT bruh these trex fanboys
@@GotamaFusion bruh this arguements lasted to long I think we should agree to disagree many paleontologist s argue we don't know the full truth as we have never seen a living one all I would say is that the internet is full of lies and no one not me or you or anyone knows the true size of a 65 million year old dino
The spinosarus is bigger
Megalodon 50-60feet
Yeah t.rex was fifty feet and megalodons discovered fire heck while we're at it raptor where 300 feet long :)
A true King
It was 15 meters not 12
Isn't the giga 8-10 tons
noooo, it was around 7 tonnes
It isn't likely T. rex was a giant 15 meters long because it would become slow with weight and isn't ideal for a hunter status
Blue Gaming Well it was proved trex couldn't sprint.
Jack Leo still it's speed would be decreased najorky
Majorly?
Blue Gaming I know, turns out they could only run around 20mph, way less that the previously thought over 40mph.
Why? It didn't hunt small game. An adult that size is a big game specialist hunting animals that were just as big and slow.
