Titanic by Fragillimus335 Titanic by Fragillimus335
Amphicoelias, possibly the largest sauropod and largest animal yet discovered, shown with two of the largest mammals alive today. The Blue Whale at a massive 28 meters long and weighing ~140 metric tons, and the Asian elephant at 3m tall and ~4 tons in mass.

Edit: I redid this scale with a more accurate reconstruction of Amphicoelias. Still seemingly the largest animal ever at about 70 meters long. Only known from one dorsal vertebra estimated to be about 9 feet tall, scaling from related sauropods gives numbers clustering in the 65-75 meter range. At the size I depict here a likely weight would be around 175-195 metric tons (Assuming slightly higher pneumaticity than seen in Diplodocus). Recent studies show that sauropod necks tend to lengthen to the power of 1.35 in comparison to smaller relatives. Since diplodocus had a ~6.5-7 meter neck, Amphicoelias could have had a neck 2.5^1.35 times as long....That's over 20 meters of neck! The only possible contenders to Amphicoelias's size are the Blue Whale and the very poorly known Broome Titanosaur.

All scaling is imprecise and based on Amphicoelias assuming similar proportions to Barosaurus and Diplodocus.

It was probably near that number.  60-75 meters is 197-245 feet.  I assume that it would have a proportionally longer neck than Diplodocus, being so large.

Well Godzillasaurus is supposed to be around 60 tons, so it would be a pretty good size predator of Amphicoelias...  A pair would be safer though!

wow GREATOOOOOOOOOOOO.thank you because of you,re great work.just one thing.are you sure that  amphiceolias was about 70-80 meters?!i heard amphiceolias was about 62 meters and 135 tons while bruhathkayosaurus was shorter(around or about 44-45 meters)but heavier(about or around 190-220 tons!!)please tell me if you know anything about this that is realy estimates says amphiceolias was about 70-80 meters and about 245-250 tons!!let me that i give you some datas about the(probably)largest meat eating creature that had ever lived untill we know.it,s name is kelmayisaurus with a lenghth about 22-23 meters and a weight in min 25 tons that was one of allosaurus cousins with hands that was more than 10 feet or 3 meters even untill around 4 meter or 13 feet or even more.please when you read this comment tell me you,re idea and anything you know specialy about kelmayisaurus and one thing before i go.you can see some pictures of kelmayisaurus in deviantart by searching in search part.thank you very much and sorry that it was a little long.please tell me you,re idea and you,re data thank you i am waitting.

Hey! Thanks for the compliments! It's good to see some more dino fans out there!  Alright, I'll give you all the answers! :D  

1. Amphicoelias is very hard to estimate because it is so badly preserved.  But, if we just size it up from other diplodocids, then it seems like ~75 meters is a good guess for it's size.  It would weigh about 225 tons at that size.

2. Sadly Bruhathkayosaurus is probably a fake. :(   The photos of the bones look like normal rocks, and the paleontologists who discovered it have NEVER got a dinosaur right before, they always mess it up.  So I think it is best to count Bruhath out of the race for biggest dino.

3. Kelmayisaurus is another mistake, it is actually a sauropod dinosaur, but the guy who found it identified it wrong...  Spinosaurus is still by far the biggest theropod yet known.

4. The 3 meter arms are real though!  But they belong to an animal called Deinocherius.  It is thought to be a giant ornithomimid, like Gallimimus.  And with arms that big it was probably about the length of Tyrannosaurus, but quite a bit lighter.  Like 12 meters long and 3-4 tons.   There are also hints that Therizinosaurus might have had arms up to 3.5 meters long!  with claws ~1 meter long!!!


Thanks for all the questions, I hope I helped! :D

thank you alot my dear friend.:happybounce: but just one thing.one of my friends called harry(maybe you know him.he is one of devians like you that realy like prehistoric animals like dinos.)has an art work that he said in that bruhathkayosaurus probably was the largest predator of all time time that it can eat whole of most theropods with just one bite?!!!Fear OMG omfg something like a giant abelisaur with atleast 4-5 meter head and a length about 40-45 meters long.Eyepopping i don,t know but if you can tell me something about this that i tell him please tell me my dear friend.thanks for you,re reply i was realy waitting.thank you and please tell me you,re anwer faster or as fast as you can.thank you alot my dear friend.=D (Big Grin) =D (Big Grin) Aww

No problem! Iv'e seen that deviation, but it's a "what if" April fools picture, because back when Bruhathkayosaurus was found it was only known from a smashed up tibia.  The paleontologists thought it was from a huge theropod, but later on it was revealed to be a very poorly preserved sauropod. As a sauropod Bruhathkayosaurus MIGHT be real, but I doubt that it is very big.

This is what it breaks down to:

Bruhathkayosaurus is a giant theropod- 0%

Bruhathkayosaurus was a giant sauropod-10%

Bruhathkayosaurus was an average sauropod-50%

Bruhathkayosaurus is just a bunch of rocks-40%

hi my friend.thanks a lot for you,re answer.:) (Smile) well this things are more on guesses and many things can be right.
who knows:-? (Confused) maybe bruhathkayosaurus was a giant theropod or maybe was a giant sauropod(i think it is more possible till it be a theropod.)or maybe non of this:D (Big Grin) but whatever this guesses and this data,s are valuable and i hope that we can to underestand the truth but even know with this data,s we can have good guesses and theories.but in my opinion it is more possible that it was a giant sauropod and i don,t think that it be imposible that it was a even a theropod.:D (Big Grin) but i think this more possible that we find other fossils in future in n or x years later(maybe 1 year later,maybe 2 years later,maybe 20 years later maybe in next century or centuries or maybe even maybe even tomarrow or few minutes or even few moments later.but i am really happy that i talked with you i mean have contact with you.and i love my friends thanks and goodbye and i hope to see ya.Love

There is really no chance at all that Bruhath was a theropod.  No theropod that size could even find enough food to survive, and it would never be able to stand.  It is possible that it could be a huge sauropod, but like you said, we need to find more fossils in the future. :D  

Oh, I forgot to tell you something... There is one mysterious sauropod that is about the same size as Bruhathkayosaurs.  It doesn't have a name yet, but most call it the Broome Titanosaur.  It is known only from GIGANTIC foot prints 1.7 meters long!  If it had feet like other titanosaurs it was probably ~40 meters long and ~150-180 tons in weight.  But once again, we need more info.

You may wanna make the Amphicoelias somewhat chunkier(based on Scott Hartman's skeletals' flesh outlines, and also the general rule of larger animals being bulkier) and see how large it looks! :D

It actually is just a tad chunkier than his Barosaurus, which I scaled it from. Although the weight might be closer to 260t. :D Although be it 245 or 260 tons, you wouldn't want it angry with you.

Oh, they are out of scale now, I revised my Amphicoelias estimate down to ~78 meters. In this image I think I scaled it to ~85m, and the Blue to ~28m. I suppose it would still work for a "trophy" specimen of Amphicoelias.

Dear sweet God in heaven! Wouldn't that be a sight to see? I can't imagine that many members of this species would exist at the same time, not when there were smaller sauropods that could reach full size much more quickly because they were smaller. How long do you think it lived for? The most recent estimates for sauropods like Diplodocus or Argentinosaurus are between 60 and 70 years.
Reply
:iconfragillimus335:
Fragillimus335 Featured By Owner Feb 12, 2013  Hobbyist General Artist
I would assume Amphicoelias was quite the long lived species...probably 70-110 years? (WAG-wild ass guess) Most giant sauropods reached adult size in just a couple decades, in fact, the oldest sauropod yet found was only ~35 years old. Most mounted Brachiosaurs and Diplodocids are only subadults!

:iconzinnorokkrah:
Zinnorokkrah Featured By Owner Feb 12, 2013
That is indeed astounding, but most weight estimates these days are half what they used to be because no one was accounting for air sacs and hollow bones. Diplodocus is estimated at 12 tons instead of 24- though that's still monumental, it's a lot lighter than we used to think.
Reply
:iconfragillimus335:
Fragillimus335 Featured By Owner Feb 12, 2013  Hobbyist General Artist
Yep, things are getting a lot lighter around here... :) But large Diplodocus species could still hit ~25 tons. And even being highly pneumatic Amphicoelias weighs north of 275 tons! :0
