  • Sorry bro but Amphicoelias was the longest not the heaviest amphicoelias weighed 122 to 135 tons Bruhathkayosaurus was the heaviest and averaged 139 tons

  • amphicoelias

  • Seismosaurus is longer than diplodocus, and they are different

  • @jattyization um no they arent :P look it up

  • @jattyization Seismosaurus is in fact a species of Diplodocus, D. hallorum, which is, of course, longer than the other diplodocus-species (D. longus, D. carnegiei and D. hayi )

  • Why is amphicoelius so unknown to people? Oh and ultrasaurus is just a supersaurus to let everyone know

  • 6. Sauroposeidon Proteles

    5. Diplodocus Hallorum

    4. Supersaurus Vivianae

    3. Argentinosaurus Hulinculensis

    2. Bruhathkayosa Urus Matleyi

    1. Amphicoelias Fragilimmus

  • @animefan2861 lets see......... im most familiar to # 1,3,4, and 5

  • wrong argentinosaurs is the largest

  • @letalvoz no, the last one, whose name is to long to post is so large that it dwarfs all known sauropods, even argentinosaurus, thats not to say argentinosaurus wasnt god damn gigantic.

  • @letalvoz ur wrong, amphicoelis was at least 35% larger, taller, and stronger than argetinosaurus, but most dinosaur documentaries say argentinosaurus because argentinosaurus is more famous, but amphicoelias is bigger

  • there can never be any certainty on this. from last reports. the bruhatkayosaurus is supposed to be the biggest if u extrapolate its size in comparison to other sauropods. it might even be bigger than the blue whale with estimates of weight at around 140 tonnes making it the largest animal the earth has ever seen....

  • @TheMaskwa Wrong, Amphicoelias is definatly the biggest. It is around 200 feet long making it eay bigger than a blue whale. Bruhatkayosaurus is only around 140 feet.

  • @isaroytrev3 u are talking only about the length. amphicoelias was definitely longer but the backbone of the bruhatkayosaurus was not hollow like other sauropods. it was thick and dense making it the "heaviest" and hence the biggest. the other sauropods had evolved better with hollow backbones adding much less weight to the body. so in terms of weight, the bruhatkayosaurus is supposed to be heavier. also the blue whale is still considered the biggest ever by experts...no dinosaur.

  • @TheMaskwa i agree with you, and it irrates me that people say blue whale is the biggest animal ever thanks to bbc (dont get me wrong i like bbc, just not that sentence). The blue whale is 80-95 ft and almost 150 tons, amphicoelias was like 150+ ft and weighed 135 tons, but bruhatkayosaurus was shorter and weighed more (120+, 175 tons). :D

  • @shreeyadz870 actually the largest blue whales weigh 200 to 210 tons but on average weigh 120 tons. ampicoelias was longer but was lighter than the blue whale and so was bruhathkayosaurus who weighrd 120 to 175 tons and averaged 139 tons.

  • @TheMaskwa I have even read weight estimates of 200t (which most scientists currently state to be inacurrate). I personally don´t think that they are, because I´ve extropolated it´s weight based on the estimate of 100t for argentinosaurus and came to a result of 250t (which probably is too much, but then 200t seems likely to be accurate).

    So I believe that the largest animal ever was Bruhatkayosaurus.

  • @Ornitholestes1 absolutely! its what i have been saying:) and if you are actually doing extrapolations of that kind( are you a scientist?), then pleased to meet you:) im just an amateur and i like a dabbling in this field. natural history is a passion...

  • @TheMaskwa pleased to meet you too :)

    No, I´m not a scientist, but I want to study paleontology when I have finished school.

  • Amphicoelias CAN be the largest, but we really don't know yet. And people think that "seismosaurus" was 50 meters long, and Diplodocus hallorum was only 30 meters.

  • putas pinches pendejadas de mierda no creo ni una polla en esto .i. joder xd

  • Actually, People don't know if amphicoelias is the largest,From an INCOMPLETE Skeleton. But it may be up to 170 feet long

  • the amphicoelias is the dinosaur more big the universe,

    measuring 60 meters long

  • isnt siesmasaurus the biggest

  • I Heard they just found the skeleton of a Gay Dinosaur and have named it Megasaurarse.

  • @SuperMagnum83 Mamenchisaurus  was only long because of its neck.

    I still convince myself that Amphicoelias could be the mixed up bones of

    two of the largest sauropods

  • the biggest sauropod is argentinosaurus and the tallest sauropod was brachiosaurus

  • The biggest one's bigger than the street i live on...

  • Comment removed

  • my opinion is: 1.amphicoelias (55- 60 meters) 2.bruhanthkayosaurus(36 45m) 3.argentinosaurus (35-43 meters) 4.supersaurus (30-42 meters) 5.sauropodeiden (30-34 meters) 6.paralatitan (30-36 meters). diplo is knocked out since its only 5-7 meters high

  • @redcarnotaurus you missed out peurtasaurus which is estimated to be a similar size to argentinosaurus, possible slightly larger, Also there is a 35m Mamenchisaurus skeletal mount in china based on a new species of Mamenchisaurus that had neck bones a third bigger than the regular 23m Mamenchisaurus.

  • look!!! little foots grampa!!!! 0:46

  • amphicoelias is known from a few fossils and if I am not mistaken, the fossils were lost so we may never know what the largest dinosaur was.

  • no,it's not argentinosaurus

    

  • LArgest Known dinosaur is Argentinosaurus

  • @LegoDinosaurMonkey Argentinosaurus is the largest dinosaur from a substanial skeleton. only one backbone of Amphiceolias was found but it was 8.8 feet tall, the Argentinosaus largest backbone was just over 5 feet so Amphiceolias would have been much bigger. LONGEST 1. Amphiceolias 55-60m 2. Bruhathkayosaurus 40-44m 3. Peurtasaurus 33-40m 4. Supersaurus 32-40m 5. Argentinosaurus 30-38m 6. Mamenchisaurus sinocanadorum 30-35m 7. Diplodocus hallorum 31-32m 8. Paralatitan 26-32m

  • @SuperMagnum83 Okay, my book is littl old then :) I gotta byu new one... I have always dreamed being dinosaur paleontoligst as an adult :D

  • 1.amphicoelias fragilummus (60-80 meters) 2.bruhathkayosaurus (40-45 meters) 3.argentinosaurus (30-38 meters) 4.blue wale (90 meters).

  • @isaroytrev3 ble whale only (33meters)

  • @2000daysofFun 33.6m is the largest blue whale ever found, most fully grown adults are between 21-24m

  • hostly now im at the point that no 1 knowes what they are talking about, the world needs to come together and sort this shit out

  • Sismosaurus is number 2 and diplodocus is mallr tha Sauoposeiden

  • NON OF THESE SAUROPOD HAS BEEN FULLY RECOVERED. The paleontologist estimate the size of the sauropod based on the proportion of bone and comparison with other sauropod relatives. The largest, the longest, the heaviest, and the most massive sauropod based on published weight estimates is Amphicoelias fragillimus (122,4 t, 40-60 m or 130-200 ft).

  • they're bigger than me. Im jealous :/

  • Nope. The largest was Argentinasaurus.

  • @Tyrannoman11 Amphicoelias dwarfs Argentinosaurus Amphi's max. size is 60m Argen's max. size is only 30m

  • what about siesmosaurus

  • @jr87001 seismosaurus was actually a species of diplodocus according to wikipedia

  • @htfamily ok you trust wikipedia were anybody can edit the page..........ok if thats not a fail nothing is sory for makeing fun of you btw

  • @htfamily maaaaaaaaaaaaaaybe. So until someone can prove it, still Seismosaurus is Seismosaurs, and nothing else :P

  • @htfamily and we know Wikipedia is ALWAYS right....

  • brachiosaurus and apatosaurus are larger than diplodocus

  • For a lighter hearted glimpse at the subject of dinosaurs, please do check my channel, episode 73 where my fool of a friend shows his ignorance on the subject, even thinking a thesaurus is a dinosaur...

  • @deviljhodemon did you just copie that down?

  • amphicoelias fragilimmus a genus of herbivorous sauropod dinosaur that includes what may be the largest dinosaur ever discovered, A. fragillimus. Based on surviving descriptions of a single fossil bone, A. fragillimus may have been the longest known vertebrate at 40 to 60 metres (130 to 200 ft) in length, and may have had a mass of up to 122 metric tons (135 short tons).

  • What about sauroposeidon???

  • Comment removed

  • Comment removed

  • @KatieMoqMax here's the thing. Sauroposeidon is Big, almost 2 times the height of brachiosaurus

    however he is merely 1/3 compared to some, other sauropods. 3rd. argentinosaurus,from south america 2nd. Bruhathkayosaurus (3 times the weight and height of diplodocus), from asia. and finally, Amphicoelias( its 6 times the length of apatosaurus and 8,000 times heavier than t.rex.) from asia. :)

  • @reddragon107 Numba 1: What part of for me don't you understand.

    Numba 2: It isn't YOUR opinion.

    Numba 3: Shut up when someone isn't even talking to you. Number 4: #lol

  • Why are you all arguing which is bigger? It's obvious that Biggestosaurus is the biggest one! Well it's as large as it's cousins, Largestosaurus, Hugestosaurus, Titanicaurus, etc. etc...

  • @anoobys ChurckNorrissaurus wins.

  • there is also bigger than brachiosaurus the seismosaurus.

  • @Vastlight2 And then the even bigger one, Argentinosarus

  • @Vastlight2 siesmosaurus and diplodocus hallorum.........are one!!!!!

    check this out at wikipedia

  • Brachiosaurus is most high than diplodocus, 

  • Diplodocus? Diplodocus only weighed around 15 tons. There is no way that it even approached its size! In fact, many mammals could exceed it in size.

  • Have we all forgotten about Brachiosaurus?

  • @acarch Supersaurus is almost 1.3x bigger than the brachiosaurus, it's not actually anywhere near the biggest. It's still fucking huge though :D

  • @TheAlexFarr Thanks for the info. WOW! thats just crazy! What a sight it would be to actually go back in time and see that walking around in the flesh.

  • what about seismosaurus?

  • amphicoelias, is the largest

  • amphicoelias= 60-80 meters

  • @MacZambrottVEVO that would be 75-102

  • Argentinosaurus grew to 40 metres long and stood 20

  • @XjerichoX12

    20 what?!?!?!

  • @N00bcrunch3r metres high

  • @N00bcrunch3r

    Well be sure and clarify that. Don't just stop in mid-sentence.

  • @XjerichoX12 Estimates put the Argentinosaurus discovered at between 30-38m long if the specimen found was average then a big individual would have probably got to 40m. Argentinosaurus was about 7m at the shoulder and held its neck horizontal so was never close to 20m tall. Sauroposeidon was smaller than Argentinosaurus but held its neck vertical and may have reached 20m tall.

  • @SuperMagnum83 actually aregentinosaurus fossils such as the below elbow lenght one found it was near enough 2 metres also it held its neck high to reach the huge confiers above its head meaning it was a rooftop grazer it stood up in total from foot to head at about 15m so your right i thought it was truely sized at 20m because nigel marven said it was at this size but large female would have reached atleast 17m tall.

  • @XjerichoX12 even if it held its neck high like Brachiosaurus its impossible to say how tall it was because the neck has never been found, titanosaurs had medium sized necks, to reach 17m it would have to have a 10 - 11m neck, it probably had a shorter neck than this. for the record the shin was 1.55m and humerus 1.81 including the foot the forelimb hieght was around 4m the hind limb was much bigger around 5.5m, Sauropods with bigger hind limbs are usually depicted with horizontal necks.

  • Send this vid to the new PREHISTORIC CHANNEL. PREHISTORIC CHANNEL just launched.

  • Will beople stop saying Seismosaurus when it doesn't exist its name is Diplodocus Hallorum now and its no way near the biggest. Gillette made a mug of himself when he estimated a 52m length because he misplaced the bones. The corresponding bones of D.hallorum (Seismosaurus) are 1.25 times the size of a 26m Diplodocus Carnegi so 1.25 x 26 = 32.5m, the mounted skeleton somewhere in the USA measures 33m so it's big but not as big as others like Supersaurus who's corresponding bones are 11% bigger.

  • Of course these are estimates based on discovered specimens, there could be new discoveries of bigger specimens that could increase the sizes or new theories that could decrease estimates so the sizes are just a rough guide especially for Amphicoelias, Puertasaurus, Bruhathkayosaus & Sauroposeidon. Although evidence is strong for Brachiosaurus, Argentinosaurus, Supersaurus, Mamenchisaurus, D.hallorum & Futalognkosaurus we can be quite certain that they attained those lengths.

  • Top 10 Biggest (estimated length)

    1.Amphiceolias 56-62m 2.Bruhathkayosaurus 40 - 44m 3.Supersaurus 34 -42m 4.Puertasaurus 32 - 40m 5.Argentinosaurus 30 - 37m 6.Diplodocus Hallorum 31-35m 7.Sauroposeidon 30-34m 8.Futalognksaurus 26-32m 9.Mamenchisaurus 23-30m 10.Brachiosaurus 22-28m

    the guy below that posted a 60m length for argentinosaurus is mental when the most conservative estimate puts argentinosaurus at 30m and the most liberal 37m.

  • @MrRebuttal Hello! Amphicoelias,Argetinosaurus,Su­persaurus,Seismosaurus and Bruhathakyosaurus are bigger then The Blue Whale!!

  • @redragon107

    Blue Whale was much bigger in mass, also don't forget that sizes from sauropods are not very accurate because all we have is a few fossil bones, so it's not easy to get a reasonable estimate.

  • that's amazing, imagine them mating and the size of ther eggs, it was a world of giants with no room for our ancestors who were hiding in holes beneath the surface

  • 1. Amphicoelias 62 meters 2.Argentinosaurus 60 meters 3.Seismosaurus 52 meters 4.Supersaurus 40 meters 5.Sauroposeidon 39 meters 6.Brachiosaurus 35 meters

  • Amphicoelias, Argentinosaurus, Seismosaurus, Supersaurus, Brachiosaurus Diplodocus

  • @memebutler yes amphicoelias did exist you idiot AMPHICOELIAS IS THE BIGGEST CAUSE IT REACHED 200 FEET LONG ITS THE BIGGEST THING EVER LIVED

  • brachiosaurus just got 25 to 35 meters long and about 14 meters tall but there are a lot more dinosaurs who are a lot bigger, longer and taller than brachiosaurus.. media just doesn´t goes deep enough.. so they keep telling the same over and over for decades... the longest dinosaur ever found (till now) was over 85 meters long...

  • @konjunktion26 The mounted skeleton of Brachiosaurus brancai is 12m tall and 22m long but there has been bones of Brachiosaurus Altithorax that were 15 % bigger so it would have been 13.8m tall and 25.5m long but it also differed in that B.altithorax had a 20% longer torso and a 25% longer tail adding another 3m so the B.althithorax discovered was probably 13.8m tall and 28.5m long. So a large individual could have attained a 30m length but there is no evidence for a 35m Brachiosaurus, not yet.

  • @SuperMagnum83

    35 m? nothing bigger yet? but they found many years ago a over 70 m long sauropod and the scientists think that the more far you go back in past the bigger the animals got and some scientists even say there are many huge animals & dinosaurs they still didn´t found... so you can´t say that the biggest dinosaur was 35 m long when scientists found a over 70 m long sauropod and this was not the only dinosaur over 60 m long... i don´t know why official facts are always lies...

  • SHUT THE F@#% UP!AMPHICOELIAS IS THE BIGGEST!

  • HOLY $#!T AMPHICOELIAS MIGHT HAVE EXSISTED IT MIGHT NOT HAVE. YOU PEOPLE ARE NOT SIENTIST AND YOU DON'T KNOW IF IT EXSISTED OR NOT SO SHUT THE ---- UP

  • FIRST OF ALL , im gonna get some facts straightened out here. 6. supersaurus might be a large diplodocus.5.Diplodocus is fine with me.4.Sauroposeidon might just be fine.3.Bruhathkayosaurus might have never existed..2.Amphicoelias might have never existed either.1.Argentinosaurus is the largest of all sauropods and dinosaurs for me. so 3 sauropods eliminated out of 6.

  • @memebutler you are right about the amphicoelias however scientist found a huge bone which was apart of amphicoelias and thanks to modern techonology amphicoelias would be the biggest of them all

  • you should have put sizemosaurusits 50 meters long

    

  • if i were an argentinosaurus i would crush you with my feet until you were seriously served.

  • siesmosaurus is classified as a large diplodocus. like nanotyrannus is a t-re in a different stage of development.

  • amphicoelias is not the biggest dinosaur i bet it never existed :P ARGENTINOSAURUS IS the largest. get your facts right and dont turn it into crap.

  • ultrasaurus never existed i guess.. and Amphicoelias probably never existed either.so those sauropods are eliminated. heres my order. X- never existed maybe.

    1.Amphicoelias (X)

    1.Argentinosaurus

    2.Bruhathsokayasaurus(X)

    3.Brachiosaurus(trust me on that one.)

    4.Supersaurus

    5.Diplodocus

    6.Sauroposeidon

    -7.Ultrasaurus (XXXX)NEVA EXISTED is why i put it as negitave seven.

  • @memebutler hey!!! try to search all ur X's on wikipedia!!!! go on!!! just try it! if there is a page, your a noob if there isn't we are the noob. deal? oh 1 more thing brachiosaurus is SMALL FRY compared to the two largest sauropods. and we are like nothing but dust. oh btw there are 2 species of Ultrasaurus, ultrasaurOs that lives in the north A. and Ultrasaurus that lives in south korea.

  • ultrasaurus never existed i guess.. and Amphicoelias probably never existed either.so those sauropods are eliminated. heres my order. X- never existed maybe.

    1.Amphicoelias (X)

    1.Argentinosaurus

    2.Bruhathsokayasaurus(X)

    3.Brachiosaurus(trust me on that one.)

    4.Supersaurus

    5.Diplodocus

    6.Sauroposeidon

  • ultrasaurus is bigger then all of them

  • diplodocus was smaller than Brachiosaurus...so what do you mean by ignoring him?????????????

  • Comment removed

  • Hello! What about Ultrasauros? That has been proved the biggest!

  • @cofloabi ultrasauros was a fraud, the creature was a mixture of bones from a very large brachiosaurus and supersaurus, at the time it was thought to be a new dinosaur but we now know it wasn't. even if ultrasauros had existed its projected 18m height would be surpassed by sauroposeidon and 30m length beaten by many others anyway.

  • argentinosaurus is 140 ft so it should have been the BIGGEST. in caps for  a reason

  • @memebutler

    Amphicoelias was estimated to have been 200 feet long.

  • @memebutler - Not very true. It was a little over 100, but Amplicoelias was still 197 feet long.

  • @TheMajortoht All the estimates of argentinosaurus range from 30m (98ft) to 37.5m (123ft) and this from two partial specimens. memebutler is correct out of the millions of argentinosaurus that existed there must have been many too pass 140ft .Consider there is always freaks in any species humans average 5ft10in but some have got to 8ft. what if the projected 197ft for amphicoelias was average how big would a freak be? we don't know WHENonly a couple of specimens are found when millions lived.

  • yeah thats the biggest dinosaur in the world (brachiosaurus)

  • @franarutmen5 brachiosaurus was the tallest at 40-45ft but sauroposeidon (a brachiosaurid) has taken that crown at approx 60-70ft in height, but because not enough bones were found to make a skeleton, so brachiosaurus still holds the record for the tallest skeleton on display.

  • @franarutmen5 - Brachiosaurus was not near the largest dinosaur in the world. Diplodocus and Argentinosaurus were both about the same length(89 to 100 feet). Amplicoelias was twice as big as that. Brachiosaurus was NOT the largest.

  • @TheMajortoht agree but for a long time brachiosaurus was thought to be the biggest remember the 40ft tall 76ftlong berlin brachiosaurus was a giraffititan ( small species of brachiosaurus). Bones of a different species of brachiosaurus were 14% larger and scaled up would have been 46ft tall and 87ft long. we know now it was no way near the biggest dinosaur but its not unreasonable to suggest that the biggest brachiosaurus ever (out of millions that existed) would have reached 100ft

  • imagine a herd full of mature 80-100 ton sauropods walking across flat land. that must have caused an earthquake. :) what a beautiful sight that would be..

  • @ApocDevTeam i agree i am fascinated by sauropods more so than any other dinosaur species. there are different features too, the giraffe like brachiosaurids with there dizzying height, the stocky titanosaurids with there extreme bulk and the streamlined diplocids with there extraordinary length.

  • the red color dinosaur is insane, Omg i cant imagine its sheer size if it would walk past me

  • I think it should go like this (in order of size) : 6. Diplodocus 5. Supersaurus (which may actually have ben a Diplodocus but i am including it) 4. Sauroposeidon 2/3. Sesimosaurus 2/3. Argentinosaurus 1. Amphicoelias

  • Brachiosaurus and Sauroposeidon are relatives, so there is a representative of the brachiosaur's lineage

  • WHERE BRACHIOSAURS!!!!!

  • if amphicoelias was the biggest, should have seen the documentry by now, but Argentionsaurus for me is the biggest

  • argentinsaurus is the largest of them all guys thats a fact,and this graph was so funny!!! thanks for making me smile

  • What about Ultrasaurus???

  • @LeoBruno1000 I dom't think it's a valid dinosaur any more go on wikipedia and see what it says

  • @LeoBruno1000 Ultrasaurus might never have existed

  • @MegaDemonMonkey I've discover that... i'm gone have an Heart attack...

  • DUDE WHAT ABOUT SEISMOSAURUS

  • @lucarioauraiswithme1 Not a valid dinosaur anymore, seismosaurus is actually a diplodocus

  • @lucarioauraiswithme1 seismosaurus has been renamed diplodocus hallorum because there were no characteristics to seperate from the smaller diplodocus longus.diplodocus has been seperated into subspecies, longus the well known 26m diplodocus and hallorum (formerly seismosaurus) the larger less known diplodocus at approx 40m, the initial 50 -55m estimates were to good to be true due to miscalculations and a more modest length has been devised. however amphicoelias could have reached 60m

  • What about Breviparopus and Bruhathkayosaurus?

  • Nice video, but wheres Bruhathkayosaurus? It was the second longest and it was the heaviest!

  • @TheLogankahle Bruhathkayosaurus might have never existed too. There is not enough evidence to back up that Bruhathkayosaurus truly did exist. So, the discovery might not be true. The same goes for Amphicoelias Fragillimus. The largest dinosaur that is backed with enough evidence is probably Argentinosaurus

  • Nice

  • The largest sauropods are 1-Seismosaurus 40-45m (132-150ft) 99 tonne, 2=Argentinosaurus 40m (132ft) 100 tonne 2=Paralititan 40m (132ft) 70 tonne 2=Supersaurus 40m (132ft) 65-80 tonne 3= Ultrosaurus 30.5m (102ft) 130 tonne 4-Sauroposeiredon 30m (100ft) 60 tonne 5-Brachiosaurus 25m (83ft) 30-75 tonne

  • @Kenany9 1. Seismosaurus was probably just a large Diplodocus at only 110 feet long, as evidence states. 2. Supersaurus might be a Diplodocus as well. 3. Ultrasaurus might never have existed; it might have been the bones of two or multiple dinosaurs found that they called "Ultrasaurus", or the bits of an enormous Brachiosaurus. There are only 3 valid dinosaurs in that list out of 6

  • @daguangrong nothing is a match for chuck norris

  • @Dannnneh

    No, Amphicoelias Fragilimmus would crush him! >: )

  • @N00bcrunch3r when that dinosaur steps on chuck norris, he wont go down, the ground under him would go down.

  • @Dannnneh

    hahaha very funny! [not] This internet phenomena is rather old now. Chuck Norris is just a retired actor that is no more powerful than you or I. I am also suprised that so many people like him when he believes so many things the public hates like: Christianity, Young Earth Creationism, and anti-homosexuality.

    "He [Chuck Norris does] not believe in evolution and subscribes to intelligent design." -Wikipedia

    Still like him?

  • @N00bcrunch3r Chuck Norris, dont you agree?

  • @Dannnneh

    No.

  • @N00bcrunch3r Indeed you do...

  • It's kind of surreal that today we have a living mammal BIGGER than all the dinosaurs listed. At least by weight. The Blue Whale.

  • seismosaurus might be huge but argentinosaurus is the biggest and heaviest of all sauropod and dinosaurs

  • Actually, Bruhathkayosaurus was even heavier than argentinosaurus.

  • @dyingdude22 what was the sauropod with the two rows of spikes on it's back?

  • Brachiosaurus is Second!

  • Amphicoelias 60 meters,

  • What about seizmosaurus, it's HUGE!!!!

  • @KRASFA Seismosaurus is not all that "huge" anymore, it was actually only about 110 feet long due to a misplacement of bones on the skeleton, and probably was only a large Diplodocus

  • Amphilicus fragmilicus is the largest not sure of the size though so just google or wikipedia it if you dont beleive me people well its the longest at least .

  • isnt argentinosaurus the largest

  • it is the heaviest and longest but it's not the tallest

  • @thejackabad

    No, Godzilla is the largest.

  • @rax7 Haha Wtf!

  • argentinosaurus is the best

  • hey dude, what about Brachiosaurus??

  • It is not compared in the chart

  • @thrashnburn30 Brachiosaurus is a derogatory term for all sauropods.

  • @thrashnburn30 you're right, sauroposeidon was probably brachiosaurus and supersaurus was probably diplodocus. Some fragments of brachiosaurus suguest that it was about 40m long. and if you add the lenght of the banddiscs (+one fifth of the whole lenght, the're even bigger)
