How Big Is T.rex? Calculating An Average T.rex Size
Vložit
- čas přidán 27. 08. 2024
- Theropod dinosaurs bigger than T.rex may be out there, but the giant T.rex won't give up its crown as the biggest theropod dinosaur yet. This video uses GDI calculations to reveal the average size of T.rex by using the largest T.rex specimens as well as the smallest T.rex skeletons. You can use the calculation of an average T.rex size to compare in a dinosaur size comparison if T.rex was the biggest meat-eating dinosaur.

It was the largest and deadliest of all terrestrial predators. T-Rex is BEAST!
Xenosaurian yes but people say it’s overrated.
@@myusername3689 Sure, but I have very rarely heard anyone say that though. ;-)
Scotty, the Rex of Rexes, was surely the king.
we know very little about giganotosaurus size so who knows
@@trvth1s giganotosaurus still isnt bigger and probably will never be bigger
Rexy would look like a runt compared to these t rexes

Veggieboy Ultimate Rexy is 46 feet long..... but ok.
According to jp she is 9 meters tall which is almost 3 times bigger than the average trex
@@thiagohavoc so is Rexy kind of a super Rex ?
@@beckystainer7297 I guess you can put it that way yes Rexy is basically an abnormally large Tyrannosaur.
@@thiagohavocWhich jp it never says that.
Sigilmassasaurus probably doesn't even exist. It is about as vague as Oxalaia. Right now, all we have of sigilmassasaurus are a couple of vertebrae. And it is much more likely that sigilmassasaurus is of spinosaurus than the other way around. Even if sigilmassasaurus turned out to be different, MSNM v4047 will still be Spinosaurus because Spinosaurus is that specimen. It was the first spino specimen found, so it stays with the dinosaur. So if MSNM v4047 is found to be same as sigilmassasaurus, the current sigilmassasaurus bones would be grouped with spinosaurus, making sigilmassasaurus an invalid genus, not the other way around.
Is it though? I believe Evers dedicated a whole paper proving Sigilmassasaurus brevicollis to be it's own species in 2015.
"Sigilmassasaurus brevicollis shows several autapomorphies and a suite of unusual features otherwise known only in Ichthyovenator. It is retained herein as a valid taxon, and a synonymy with Spinosaurus aegyptiacus is rejected."
peerj.com/articles/1323/
And the original remains found of S.eagyptiacus is IPHG 1912, not MSNM-v4047. So we don't know if MSNM-v4047 belongs to S.eagyptiacus or S.brevicollis.
VIPERTRON CHAOS that is absolutely right
And by the way spinosaurs could’ve gotten even much heavier because of the abundance of food supplies in it’s area
And also the restoration of it being a quadruped is physically wrong because think about a huge animal like this might topple down and break some limbs
So I believe that spinosaurus could’ve reached lengths over 16 m
And maybe just maybe over 9 tons or at least 6 to 7
This aged well
YO BRO you here too ;-;
I'm surprised that the Spinosaurus is THAT much lighter. I would like to see you do a video on what makes the Spino so gracile. (Also, a request from someone who is mathematically challenged - could you not jump back and forth between kilograms and tons? Sticking to one or the other would be greatly appreciated. :) )
Nothing is official about spinosaurus size.
He agrees woth arden et al who suggested that the specimen nsnm v4047 actually belongs to sigilmassasaurus and not spinosaurus.
If this is treu(which vividen does apperently) then yes, spinosaurus is around 12 meters long and around 3.5 tonnes, if not then its around 7 tonnes by franoys.
but to awnser you question,
spinosaurus was very lightly build, the greater bone density plays a very small role, despite what people might say.
its torso wasn't particularry deep or broad, its hind limbs where proportionally small, the skull was very lightly build weighing "only" ~140 kg while t.rex skull was 500+ kg! (im using NSNM v4047, not FSAC kk 11888)
and you might think the sail adds a lot but it was only estimated to be ~250 kg for NSNM-v4047... but like i said, this might not belong to spinosaurus.
the sail of FSAC kk 11888 would be around ~150-200 kg im guessing.
this ads up to an animal which might not weigh as much as you would think if its 12 to 15 meters long.
here you have the GDI results of NSNM-v4047, keep in mind this animal is 3 meters longer and weighs more then 2 tonnes less the Seu by hartman and snively's calculations
cdn.discordapp.com/attachments/226476069128110080/463482369270349825/SpinosaurusGDI2.png
and again, this might be to big and it might not, depends on if it actually belongs to spinosaurus in the first place,
FSAC kk 11888 was a sub adult was weight around ~3,1 tonnes and was only 11,4 meters long

@@svenheuseveldt7188 Thanks so much for the info! That Spinosaurus could be 3.5 tonnes or 7 tonnes highlights a central challenge in paleontology, and a video that covers the ground you went over in the comment above would be great. Especially as we constantly hear that Spinosaurus was "the largest theropod." Thanks probably to Jurassic Park III. My own introduction to Spinosaurus came in a wonderful book I still have, "The Dinosaur Data Book," published in 1990. In it Spinosaurus is described as "perhaps the longest but not heaviest of all theropods." That description seems to be holding up pretty well.
@@seanledden4397 i suggest you watching these two video's
like i said, vividen agree's with arden et al.

this one is pretty long but worth the information about spinosaurus in general.
czcams.com/video/6oCqSqY7FiI/video.html
and also keep in mind when watching this video that this video was uploeaded before arden wrote his paper
@@svenheuseveldt7188 That's a fantastic answer you gave! My opinion on Arden et al (2018) has somewhat changed since uploading that video. Now I agree with Franoys that we don't know which animal MSNM V 4047 belongs to until we find more preserved rostra of either Spinosaurus or Sigilmassasaurus to compare them with. It could be either, so the maximum size of both animals is completely up in the air right now.
And yay we got Scotty the Rex of the Rexes, 13 meters giant
Yep, and people said there woulld not be a T-rex bigger than Sue.
I’m sure there are t-rexes considerably larger than Scotty or Sue. Think about it. They were around a few million years and we only have like 50 found individuals. A lot by dinosaur fossil terms but not in terms of finding an actual maximum size
@@bradysmith4245 what i think is all of them are still in rock removal progress so they has not been studied yet by the paleontologist to messure the size/lenght

I keep seeing different body figures of T-Rexes. Does that mean T.Rex's social life, is to look different, to identify other members of the same species?
They most likely did that by smell if they even socialised at all.
Why do I get the feeling there's bigger specimens out there to be found? Apparently some of the biggest Rex's discovered were found out to be juveniles.

There is no therapods bigger than t rex. T rex is the biggest therapod. If you have proof that there is any therapod bigger than t rex then let us know
I love your synopsis! Everything to me has always been about scale. Living and non-living. Great work!
RSM P2523.8 has length estimates from 12.6 to 13.1, Scott Hartman has calculated with 12.7 and 8.8 tons while Franoys with 9.6 tons, and the most exaggerated ones go to 11.5 tons... you took the smaller ones estimates, it's nice to take varied estimates like the ones I've quoted.
Dan Folkes estimate mass a 10.400 kg
Re Gigantosaurus, I just looked it up and apparently he misspoke. It's a late Jurassic sauropod from England, not to be confused with the enormous Jurassic theropod of South America named Giganotosaurus.
Scotty is 10,400kg - 11,000kg! While Sue could be 9700kg - 10,200kg! While Scotty is 3.9 meters at the hip and Sue is 3.8 meters.
Can't wait for the Tufts-Love Rex to be finished.
Same! I remember the excitement when it was discovered, and I'm still feeling it!
SV-POW says the laser scanning method used in A Computational Analysis of Limb and Body Dimensions in Tyrannosaurus rex with Implications for Locomotion, Ontogeny, and Growth is more accurate since it's actually measuring the skeleton. I can't find it anymore since it was a reply to my comment in their site... somewhere.
The holotype is a very incomplete specimen. The skull is restored from several different specimens. Not saying it's bad, just not even close to being complete.
AMNH 5027's height can't be trusted since it's a mix of T.rex and scaled up Allosaurus legs.
MOR 980 is pretty a decent skeleton. I don't recall any weight estimates, but it's around 12 meters.
Don't know if I trust Samson's numbers since it's in private hands and never officially documented. The number come from an auction site.
King Kong is relatively complete according to Terry Glenn Ciotka. It's also in private hands. I THINK it's in Hong Kong. No numbers. I think Terry says it's around 40 feet or 12.1 with a bone count of around 45% complete. Terry is also responsible for excavating Tristan.
Victoria is coming, though according to Terry Glenn Ciotka (yes, they found another one) it's not fully grown, but already very close to Sue in terms of size. Victoria is very complete. Tons of paleontologists have been studying it behind the scenes for at least a year now.
Weight estimates are tricky. Too many variables. We can't even tell you exactly how long Sue is (you say 12.35, official published paper says 12.29 and Dave Hone believes another meter of the tail is missing) , let alone factor in things like muscles, organs, fat, skin, blood, and among other factors in an extinct animal.
Loved this video, would love to see a spinosaurus size average, as you have done a max size
I dont understand why you kept saying Sue is the largest when officially Scotty is the largest trex known.
T rex is awesome.
Using the data of these reliably measured specimens and not the potentially giant incomplete few floating around, the normal distribution gives 1 standard deviation of ~0.65tonnes and a range maxing out just over 10 tonnes, which seems quite reasonable. If those incomplete specimens are legitimately that big though,that changes things for the even bigger
Scotty 13 meters long and probably a little bit more than 9 tones and for height I dont know
@Testificate He weight 19555 lbs
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.
Heres is the final form of Spinosaurus due to latest research:
czcams.com/video/hg2Bd7e6c7o/video.html
scotty was 13 meters and 20k lbs
But didn't you say spino was 50 feet and 7-8 tons back in 2017
Maybe he did, but we now know that's not the case. It's likely Spino was 6-7 tons because it would make it more hydrodinamic, and his was miscalculated. And it was at most 47 ft.
But now it's 34 feet & 3.3 tons in 2023
Question when are you going to Mexico and will you still make videos and do livestreams while you are there?
I'm leaving in six days. I've worked really hard over the past six months making enough videos to release at least one a month while I'm gone, but I won't have internet access except for email updates so no livestreams :(

Okay have a nice trip.
P.S. I watch all of the livestreams but I am on mobile so I can't talk on them.
@@lockdown13trd22 Thank you! And I totally understand.
I'm seeing articles today (March 2019) quoting Scotty as 13m long now and thicccc as you say. Any chance this will change the GDI estimates to upwards of 9000kg?
In the 2023 Dan Folkes estimates Scotty a 12,37-12,4 meters long and weigth is by volumetrical analysis 10.400 kg
I was waiting for you to list the rex specimen from the LAMNH lol
Jurassic Park: let's ruin it's whole career
I’d say 30-40 feet long with extreme abnormals (that we may well never find) approaching 50 feet.
Cool dude, But I want to ask, so what is the average length and average weight for adult Tyrannosaurus rex
According to Persons et al (2019) the average Tyrannosaurus was 11.7 meters long and weighed nearly 6 tonnes. Vividen overestimates the average in this video.
@@Deform-2024 Apparently not, I'm sure the average T-rex will weigh more than 6 tons (not nearly but more) there a specimen named Stan that has a length of 11.7 meters and a weight of 7722 kg, and besides, isn't the booth still under 20 years, I'm sure he hasn't grown to full adult size.
@@Deform-2024 But I'm sure the age range of adult T-rex may be from 18 to 20 years and over. Specimens such as Sue, Trix, and Scotty are T. rex who are quite old. and it looks like the average T-rex will weigh 7+ tons (not nearly 6 tons as you type), while the largest weight can be almost 9 tons or maybe more.
@@DOHCx2STROKE You think eh? That's not a source, sorry.
@@Deform-2024 hmm, but I'm sure that proves that the T-rex will weigh up to 7 tons or more even though its body length is only 11.7 meters, than what you typed in that the 11.7-meter T-rex will weigh nearly 6 tons even though on average it will weigh more than 6 tons. And remember that T-rex will continue to grow into old age as well as Scotty, Trix, and Sue specimens which weigh more than 8000 kg
I was hoping for a normal distribution but since you've got this data i;ll use your data and come up with one. Here's the thing that interests me the most. Out of all the specimens we have to take into account they were all likely average. current estimates say there were probably 2.5 billion trex allive at one point. If we're taking this into account the chances that these specimens deviate outside of 1 or 2 standard deviations is low. meaning these could be the average sized ones and not necessarily the largest of their species.
(looks at videos) (sees vividens new video) *CLICKS*
Theyve found only a few dozen adult T rexes and the largest are quite similar in size so they haven't found any outliers in size , it's been estimated that over the millions of years they existed as a species that there were billions of them but not many at any one time, my money is on the biggest that ever lived being substantially bigger than Scotty or Sue
Sue is to small its 10,6T(i dont remember the actual weight of sue its somewhere around that), and scotty is the biggest btw at 11T
Scotty and sue are NOWHERE near average rex weight
How do you know Scotty is now 11 tons. I thought most people still don't know & believe Scotty is 9 tons
So..how tall is a sigilmassasaur and Spinosaur? could you give me estimates?
Cardinal Jwfk Animator 658 around eight feet at the hips.
There too much unknown about these that the info we have right now is bound to chance, so to give an accurate estimation is almost impossible.

You could redo the video of the average size of the Tyrannosaurus rex with the updated mass and length and whit E.D. Cope(Copium rex) and "Bertha"???
The average T.rex is long 12 meters(39,4 feet)and weigth is 9 tonnes
Everybody is clearly waiting and hoping for a better find of a bigger T-REX an alpha or omega for the queen or king of lizards!
I love these accurate dinosaurs, the info on this will come in handy when I use it.
I only have one question, how is spinosaurus only 3.5 tons despite being 12 meters long and having a barrel shape body( more so then t.rex, but I'm not here to start that) with denser bones then other therapods, as they spend most of their time in or near water?
I just find it confusing since I saw spinosaurus being around 5-6 tons or to make a specific range 5.4-6.2 tons then the average siligamasaurus would weigh 6.5-7.8 tons. Those are minimum to maximum so let me state the averages spinosaurus weighs 6 tons for males and 5.4 for females then siligamasaurus weighs 6.5 tons for females and 6.8 tons for males then for T.Rex the average would be 7.5-8 tons for females then 6.8-7 tons for males. I just want some clarification on this and these are my honest estimates for the average sizes.
spinosaurus is a thin animal for its length its skull is lightly built it has short back legs this all impacts its weight you can see how thin it looks when compared to tyrannosaurus when you compare there skeletons together qr.ae/TUhKst that link has some great comparison pictures and you can see how much slimmer spinosaurus is
Jeremiah Bryers Tyrannosaurus had a much larger torso than spinosaurus. Massively larger. It is just thicker everywhere
Jeremiah Bryers. Fsac-kk 11888 does not weigh 3.5 tons. That is only an estimate. We barely have any fossils of spinosaurus, with all specimens combined. So that estimation is 90% wrong. People these days beleive everything they read. Also sigilmassasaurus isn't bigger than Spinosaurus. MSNM v4047 does not belong to Sigilmassasaurus, as that was yet another theory. All of this is about as accurate as the quadrupedal Spinosaurus theory back in 2014.
@bloodes Nope.
It'd be cool if you included their age as well.
Wow! That's impressive. I'm no scientist and a lot of this goes a tad over my head, but it's still interesting to note that while the 'average' Rex taps out at about 30-40 feet in length, some got a tad larger and longer? And what they lacked in length and height was made up for in bulk? Heh. I wonder if all that heft helped them hunt the Ceratopsians and Ankylosaurids? Those were some tough animals.
Lol no adult specimen of T.rex is 30 feet long
Awesome!!
How on earth did u get the average mass for mapu, giga and tyrannotitan to be over 7 tonnes. Franoys puts their max mass at below 7 tonnes
I used the 10% statistical scaling gained by Sue being 10% larger than the average T.rex and applied it to those GDI estimates. Our sample sizes for those other theropods is much smaller than with T.rex, so assuming that those specimens represent the absolute maximum is fallacious.
Veterupristisaurus Milneri, daviantart isn't always right you know...
The Vividen most adult specimens of mapusaurus are found to be around 10m so it could be that the much larger adults are around if not maximum size. Both carcha and giga Holotype and neotype are around the same size as the massive adult specimens of mapusaurus and since they are all closely related it doesn’t seem unlikely that they are their potential max size
Very interesting and informative video. I'm very curious about one particular aspect of T rex's anatomy, the height. Do you consider the height at the hips as the highest point of the real animal? Or its head might actually have been a bit higher due to its posture? For many years I've heard many documentaries claiming that T rex could reach heights of about 5-6m tall! Yet if we consider all of the T rex's fossil record, none of the specimens surpasses the 4m barrier...
I believe it works differently.
We can actually muessure the lenght up to thier hips. Where as if we want to muessure how high its head would be we would have to make it posture first. And thats made up by us. Maybe only by a few inches but therefore(i beleive) we muessure by hip height and not head.
It is all based on the posture the animal takes.
Your normal walking posture is one thing but on tip toes you get a bit taller.
Trex being theropod is a bit different, ALL theropoda naturally have a vertical stance. When terrestrial theropoda today fight [emu, ostrich] they adapt a more vertical stance which makes them taller and more intimidating.
Trex at the hip was around 4 meters tall but if it got into a vertical stance, its tail would be on the ground for added stability, and its height would drastically increase. This stance was not practical for the animal walking but it would definetly make it look bigger and give it major height advantage against most anything.
Thank for showing me for the discord -3-
You guys know that "Scotty" is also female, right? They only named her that because of what they were drinking.
???
We have no way of actually knowing what sex a dinosaur is. Well, really any prehistoric animal.

No way spinosaurus was three tonnes
lmao why was the spinosaurus put at 3.5 tons? They had dense bones unlike the typical hollow theropod bones, a more muscled tail, and were longer than most other theropods.
This was back when MSNM-V4047 was claimed to be Sigilmassasaurus and Vividen took it at face value. The specimen in the video is the holotype IPHG 1912.
The giant spinosaurus then was classified as sigilmassosaurus.
I used the square cube law and arrived at 9155 kg for a 12.5 meter Trix. And I thought AMNH 5027 was 7900 kg?
Using Sue's 8828 kg mass and 12.35 meter length, I just got 9153 kg. Hmm.
AMNH 5027 was that big, but a further examination provided a bit of a downsize
The Vividen oh, I was using Franoys' GDI.
He had a 7900 kilogram one, and then redid it and arrived at a smaller number.
The Vividen Oh, I didn't see the more recent one. I got 9155 kg for Trix because I accidentally put 8830 kg for Sue.
What about buck from the second movie???!!!
Rexy is the biggest rex in the jurassic park franchise movies and books so the buck would be slightly smaller
Dude, you are obsessed with _T. rex_
Wheres wilkinson aka the nations t rex, its in the smithsonian museum of natural history.

They call them kings because Rex means king.
Some of the estimates aren't quite right. For example, Stan the T.Rex; Stan's holotype is estimated to be roughly over 4 meters... Peter Larson, the paleontologist whom found this specimen even confirms this as fact.
Over 4 meters what? Lenght? Height? Width?
Cause Stan was not 4 meters in height.
@@svenheuseveldt7188 Height yes. Ask, Peter Larson himself he was the one who confirmed it. Furthermore a rough estimate of the height was drawn;. the results showed Stan to have stood around 14ft in height.
@@TheMightyN Well first of all 4 meters in height equals 13,1 feet, not 14.
And second. Hartmans skeletal of the specimen has the height of the animal at ~3,5 meters.
Franoys skeletal has the hieght of the hip at ~3,6 meter(head would be almost the same)
It probably could rear up and reach 4 meters in lenght but not even Sue is 4 meters at the head...
In it's natural position it was about ~3,5 meters in height.
@@svenheuseveldt7188 In the metric system a meter can be represented by a series of numbers. So 4 meters can be converted to 13-14 feet. In this case Stan is 14 feet by about 4.26m.
@@svenheuseveldt7188 Secondly, Hartman isn't entirely a reliable source and Franoys didn't measure by it's skeletal reconstruction. The algorithim used to measure the height of each tyrannosaur specimen was estimated correctly and checked the results twice for any mistakes. I added and measure the femur bones of both Sue and Stan precisely; the results were the same.
Though that is true, Sue does reach a full height of 13 ft. The problem with Paleontology, for some of its completed dinosaurs specimens, scientists almost never include the head.
"Spinosaures is the communist godking of dinosaurs and everyone who disagrees with me can eat my ass" ~ Vividen 2018
Spinosaurus was probably larger. Since when is it 3 tons. It was 15 metres long! People think the T. rex could get up to 15 metres, like humans get higher than average, but I disagree. Look at birds. Not humans. Birds don't get way higher than the're average species size very often.
Edit: sorry o was so stupid. It makes sense that Spinosaurus would be light because it’s slender. However it’s bones were very dense and it’s proven to be around 7 tons now
Spinosaurus is not just 3 tonnes. Well maybe, we don't know and we can't know for now. Ibrahim estimated a mass of 6 to 7 tonnes and 15 meters in lenght. Which is lower and less massive then T.rex. So yes, it is smaller with our current understanding.
Toostig edward I measure size in dinosaurs in length, (visual size.)
@@paleoguy2165 Well just so you know, that's not accurate.
Toostig edward no, it depends on how you look at it. Different people measure differently. You can't say it's inaccurate to measure in terms of length. Most people do, actually.
@@paleoguy2165 Just cause most people doesn't make correct... In biology meassuring an organism by only one dimension is incredably inaccurate. They are all different organic shapes, so only going by one meassurement is like i said it, inaccurate. If you want to compare sizes of animals you would need to take all three dimensions, lenght, width and hieght. too bad we can't just add them up(cause they're not perfect boxes, they're animals. You can't meassure organic shapes). So that's why we determine an animals size by weight. and for that exact reasona snake isn't bigger then an elephant cause it's longer and for that reason a giraffe isn't bigger then an elephant cause it's taller.
The elephant isn't the longest or tallest animal on land, it's the most massive(heaviest). And that is what makes it the biggest animal on land. Someone who's taller then you isn't always bigger, what if he's very fat. another reason why only factoring in one dimensions is wrong.
I hope this helped you understand why meassuring only by lenght or height is wrong.
Scott Pilgrimosaurus Rex vs the World
The hollow bones would make them closer to 5 tons. Since the walked on only two legs. They would need to weigh less. Other wise they would have less ability. Try back packing with a 60 and a 90 pound back pack. Then you will see my point. I do not believe the movie hype about the average size of a T-rex. That upper body was down sized for a reason. Like if you lifted a jeep would you make it a front wheel drive.We talking 44$!
I'm willing to believe if the spino walked on all 4s I doubt it did since it would be crushing it's own front limbs it was probably pretty fast on all 4s, it could walk on it's two back limbs but it would be very slow and weird so I don't see a proper was it could do anything properly unless it had no competition at all and it just completely intimidated everything in it's way.
I think it didn’t have to go on land too often so it would not have come in conflict with Carcharodontosaurus and Bahariasaurus too often and it probably intimidated the Sarcosuchus and other creatures that also lived in the rivers with its huge size
Spino. 3.8 tonnes ????
Yes, the very small specimen
you didn’t mention Victoria the t.rex
Wouldn't the realistic estimate of how tall and how much mass T-Rex would be or have is 12-16 feet tall, possibly 17, 6-8 tons, and 40-43 feet long, as I am no expert, just merely responding to a question I was asked about before in one of my videos.
T.rex is way heavier like stated in this video, 8 tonnes on average, no where near 6.
And it stood around 12 feet tall, not 16! Are you crazy xD
+Optimus Prime 16 feet tall would be perfectly reasonable for a head height measurement for a large individual. Hip height is considerably lower; Sue's hip is just over 12 feet high. She's also the longest T.rex specimen we have at 40.5 feet long, so an average length would be closer to 39 feet. T.rex was also extremely robust! It would have to be an exceptionally small adult to weigh less than 6.5 tonnes. Thank you for your comment!
Toostig I just said, don't know exactly how tall or how much it weighed or grew, only guessed the height, weight, and length range of the T. rex. I was asked this before, and I said, I'm no expert.
The Vividen thanks. You think the height of the T. rex from Jurassic park was what they at least got correct? Happy Halloween, btw. T. rex was my favorite since I was 11.
@@optimusprime8543 You're welcome, and happy Halloween! Yes, the height (at least at the head) seems to be the most accurate dimensional proportion of their model. Their tail was too short, and the torso was too skinny, but hey!
Not only do you not know my name, you do not know my story. I don't judge you, why would I judge you? You don't judge me do you? How can you judge me if you don't know my story.
great video
According to "the real t.rex" documentary. Tristan is 4 meters tall.
That would be incredible! Do you know if that's a hip height or skull height measurement?
@@TheVividen Not sure. It was pretty vague. They just claimed it to be 4 meters tall.
@@adumsundler4397 Hrmm. I suppose a more rigorous study is required before we celebrate, unfortunately.
@@TheVividen Yeah understandably so.
The tallest T. rex is probably 15 feet tall or lower.
How heavy is MOR 1125 ?
Average t rex size lenght 39ft to 40ft 11.7mt to 12mt.
Average height to the hip 12ft 3.7m.
Average skull size 4.8ft 147cm to almost 5ft 150cm .
Average weight 7000 to 7500kg.
No average weight for a trex is 8-9 tons
7-7.5 tons is the weight of a spino
@@theamazingnobody1082 Average?? Dude thats the big boys not average .
I think Stan is a good example of an average specimen.
Sue 9t Scotty is wat 10? They are not average they big
@@thecarnosaurchannel2819 no tyrannosaurus itself is a large animal and has an extremely robust build with a body larger and bulkier than that of an African bush elephant wich weigh up to 6-7 tons a 7 ton trex is under average weight an average trex would’ve weighed 8-9 tons with 6-7 being under average and 10 tons being the absolute max
@@theamazingnobody1082 Thats not correct .
Literally we dont know the max size and wen im talking average is the folowing .
We have 50 t rex not all are adults but of all the adults the average is 7.5 tons go pull the numbers and make the math .
Factual paleontology .
And it is all speculation btw 10 years from now may change
What about UCMP137538? :)
Want me to just tell you? Length: 40 feet long
Height (at head): 20-21 feet tall
15-20 at the head
@bloodes no the actual tallest tyrannosaurus in history if it's tell is not on the ground standing like Godzilla with his tail actually in the air like it's supposed to be how they actually walk at the head the biggest one in history was 19.5 ft tall
@bloodes I must have old info
@bloodes Scotty the biggest trex found in history so far stands at 19.65 feet
Spinosaurus was not 3.5 tons. It was more like 7 tons.
@Mqcha Hehe It was 15 meters and 7 tons.
@Mqcha Hehe Ok then.
@Mqcha Hehe Average size is debatable but I’m going with the average being 15-16 meters.
This video was made when the giant spino was sigilmassosaurus. Spinosaurus size is indeterminate rn
Now a bigger one is here so I guess new video.
Scotty
@@j.d.h.5153 Yes indeed
We need a new video because now we have a new young adult Rex named Victoria scientist are saying is the largest and second most complete to be found
Everyone is so obsessed with hip height anymore. They could obviously raise their heads a few feet higher. How tall are Scotty and Sue going by the tops of their skulls?
That's exactly why we meassure thier hip height. You can't change how long thier legs and hips were whereas you can change how far thier heads were off of the ground by reasing it's head or lowering it. For this reasons we use hip height as a mueassure of height and not the head. Hope you understand. We also don't know for sure how far of the ground they held thier heads so it's also impossible to know for sure except guess a hieght...
Toostig that makes sense. Guess that explains why some skeleton reconstructions have their heads level with their body while others have them 3 feet above like a bird would
@@bradysmith4245 Shows how little we actualy know about these animals ;)
Toostig I guarantee Scotty and Sue aren’t the max size either. T rexes were around millions of years and we only have 50 found individuals and about 10 nearly complete skeletons. There are probably some absolutely massive rexes still to be found
@@bradysmith4245 Oh for sure, we barely scratched the surfase of how big these animals could have gotten. Persons et al. 2019 also siad that these animas grew to vastly bigger sizes then we're realising right now and than what we know right now. It's only a matter of time until we find a specimen which rivales Sue in size or is even bigger than Sue. And Scotty seems to be the first contender.
Just for an example. The average African elephant is ~5 to 7 tonnes and the biggest individual ever seen is 10,4 tonnes. That's an increase in size of 73%... If we apply this to the average T.rex specimen(Stan) which is 7,7 tonnes we get an answer of 13,3 tonnes!
But this is just an example and should be taken with a grain of salt. But it does go to show specimen over 10 tonnes, maybe even 11, lived for sure... But it also goes the other way round ;) Very small individuals would also be a thing xD
I always wonder why do they measure height at the hips
Because some dinos have longer necks or some dinos might have sails
Did he misspeak and misidentify "Gigantosaurus" as a genus of tyrannosaurid? I know of Giganotosaurus as a non-tyrannosaurid genus but I've never heard of Gigantosaurus. Or maybe I misheard.
@bloodes Yes, as I found out and posted 7 months ago. Thank you.
Could you do a video on the max size of the spinosaurus?
Black Beauty(RTMP 81.6.1)? Was it an adult?
Rest in the good news ⚘ 🌚 👍 okay bye
Do think that female Tyraanosaurus Rex's are bigger than the male Tyrannosaurus Rex
@Mqcha Hehe my mistake thanks for correcting me
@Mqcha Hehe yeah also it is hard to tell the gender of a fossil
“Gigantosaurus”? What’s that? ;-)
Lone wolf You mean Giganotosaurus
en.m.wikipedia.org/wiki/Giganotosaurus
A sauropod
Gigantosaurus is a different dinosaur than Giganotosaurus and is a genus in itself
Ah yeah the originals earth owner
Scotty is chunkeh
why do you vacillate between kilos and pounds, it's all very unclear.

Corvus Corax 2.0 thank you so much.
The weight of an average full grown T-Rex was around 5000 kg which is very close to the weight of an average size full-grown elephant. However, an average full-grown elephant is about 3.2 meters high and 6 meters long and an average full-grown T-Rex is about 3.6 meters high and 12 meters long. So the T-Rex may have been very heavy, yes, but he was very very light in weight for his size.
An empty DC-9 airplane weighs in at 22.3 thousand kg and can fly. So the empty DC-9 weighs more than 4 times the weight of a fully grown T-Rex. If attached to the T-Rex's upper limbs were very long primary and secondary feathers we see that they were probably wings. And with being very light for his size, he probably could fly. The T-Rex was a very large and beautiful bird!
Also it is well known that T-Rex was a theropod, but all modern-day birds are theropods, so there really is not much difference at all between T-Rex and modern-day birds. T-Rex was a big, beautiful bird and could fly!
No an average weight for trex is 8-9 tons 5 tons is waaaaaaay to light and would be the weight of a sub adult also an African elephant weighs 6-7 tons
I heard sue was a really old trex
About 26 years old.
Scotty was over 30
@@justinoppermann3997 Scotty was 28 years old when he died
@@alenibricic9899
Oh ok.
@bloodes 30 years.old was Scotty
why some sources says trex has a 6 mt height

all of these should be called with female names. its probable that females were that big
No really true, there is no evidence to say which was larger, but if we go off their modern relatives, you will see that aside from a few species, the males are always larger, for both birds and reptiles. So it is more likely the males were bigger, but who knows until we have more evidence its up for debate, I still think males were bigger thought. :)
Spinosaurus is over 8 tonnes (maybe 9).
Spinosaurus is 6-7 tons. And at max very rarely 8 tons
Correct
