Amphicoelias Reborn! by Fragillimus335 Amphicoelias Reborn! by Fragillimus335
Yep, I was never satisfied with my first try at Amphicoelias f. So here it is, reborn with much more accurate proportions. Still a monster at 60-70? meters, and perhaps 150-180 tons. Amphicoelias was possibly the largest animal ever to live, 2x the mass of an average Blue whale, and perhaps 5 times the size of the oh-so popular Brachiosaurus. This scaling of Amphicoelias assumes that Carpenter's reconstruction of the only known vertebra is correct at 2.7 meters tall.  The centrum of this vertebra is slightly smaller than a scaled up Diplodocus, so the corresponding size would be a bit over 60 meters.  Then I added a slightly longer neck, as giant sauropods tend to stretch their necks faster than the rest of their bodies.

Also fun to note, that when rearing up, as most sauropods were probably capable of, Amphicoelias would be ~40 meters tall, or around the height of a water tower.... :)

Massive, but not impossibly massive. One of my favourite sauropods and I'm making a stop motion of two males (black) fighting over a group of females (brown)

I have a documentary idea in one episode of which this goes on the loose and destroys 200 other dinosaurs.

Well, in Amphicoelias's case, if it can catch it, it can kill it.

I've heard of Amphicoelias before. It is a very mysterious dinosaur. Unfortunately, the remains that were found have been lost and we do not know what happened to them. It seems odd that one can lose something so large. I hope the fossil is somewhere, but it may really be lost forever. What a pity. I hope we can find more remains of it.

Amphicoelias must have been an amazing sight when it was alive. I couldn't imagine standing near such a large creature.

In fact, when the elephant-sized Allosaurus Maximus standed next to an Amphicoelias, it would look like a human standing next to a Diplodocus...

Yeah!  The reason it might be gone is that is was super fragile and probably crumbled after it was found.

Spectacular as usual (I haven't been commenting because well, just got a DA account few days ago) There's one thing that bugs me though, are you sure most sauropods could rear up? I have no doubt on those slim Diplodocoids like Amphicoelias, but on those Macronarians, notably Puertasaurus or Argentinosaurus.

Thanks! Welcome to DA!! :D

The general consensus among paleontologists is that all sauropods could rear if they needed to.  Macronarians like Brachiosaurus would have certainly had a harder time than diplodocids, but the construction of their hips shows that they could probably pull it off.  Not to mention they had to make baby brachiosaurs somehow!  

Titanosaurs like Puertasaurus and Argentinosaurs actually have some of the best features for rearing, notably super huge and robust hips.  Hope that answered your question!

Not at the moment. Try searching google scholar for sauropod rearing.

I have something to say :D

~250 tonnes is about ~3.89 times the mass of the average blue whale...

[link]

Average blue whale mass is only ~64.35 tonnes, smaller than Argentinosaurus...

Damn, that is insane. I can't believe Blue's have taken such a hit. Though I am using a historical average, discounting the impact of whaling. I estimate around 130 tons. It's hard to believe, but if whaling was stopped in the 20's and 30's some of those whales would still be alive today... :(

I'm not sure, but they didn't found giant ichnites in the Morrison Formation that could belongs a giant Sauropod like Amphicoelias?

They really need to make the creature creator bigger! And add a scaling feature!

That's perfectly true. It's particulary frustrating when you make adventures, for example, a Breviparopus in one of my adventure was too small, so I had to adjust all of the Dinosaurs around of it :(

Love how you draw on paper rather than digitally, personally I too am better on paper than digitally. I'm interested in how you got your estimates for Amphicoelias - 85-90 m?

:iconfragillimus335:
Fragillimus335 Featured By Owner Feb 2, 2013  Hobbyist General Artist
The paper Carpenter wrote seems to have a mistake. When he estimated Amphicoelias at 58 meters he scaled Diplodocus up by a factor of 2.2, when in reality the scaling factor of their femurs is 3.12, so 26.25x3.12=82 meters, add a bit of intervertebral cartilage, and 85-90 meters seems pretty reasonable.

Good reconstruction, but what exactly are you implying by claiming it was twice the mass of an average blue whale?
