Supersaurus vivianae

Supersaurus vivianae - Although not the most "super" of the dinosaurs, its still a match for Dreadnoughtus, and just as fearless...*

Temporal range: Late Jurassic, Kimmeridgian, around ~153 Ma

Length: Around ~30-40 metres
Probable mass: Around ~30-60 tonnes

Etymology: Vivian's super reptile

Supersaurus vivianae is a species of diplodocoid that lived in what is now the Morrison Formation of North America. Some of its bones have once been referred to the defunct taxa Ultrasauros macintoshi and Dystylosaurus edwini. In 2015, the Eurasian species Dinheirosaurus lourinhanensis has been assigned to the genus Supersaurus. It is the longest dinosaur known from sufficiently good remains.

The first specimens, the type specimen BYU 12962, an ischium (BYU 12496), and some neck vertebrae. A more recent, more complete specimen, WDC-DMJ-021, was discovered in 1996 and was described in 2007.

The WDC specimen is estimated at ~32 metres, with a probable mass of around ~30-35 tonnes. The BYU specimen, which is rather fragmentary, possibly reached the region of ~35-40 metres, with it's mass easily ending up in the ~40-60 tonne range.

*Before you start saying "How can you say Supersaurus is a match for Dreadnoughtus? It's like 60 tonnes! You just love Jurassic sauropods too much!", take some time to read this:…

Dreadnoughtus likely massed in the range of ~36-46 tonnes, with a volume of around ~50-52 cubic metres, give or take .

The ~59+ tonne estimates are derived from a method that's known to be quite unreliable (Femur circumference methods also put a certain Tyrannosaurus-sized allosauroid at ~2.4 tonnes!)

UPDATE(2/11/2017): A complete remake. Wasn't really too satisfied with the older one TBH. New pose and a much spikier back.

It looks like Dinosaur Revolution's Dinheirosaurus (or S. lourinhanensis)

Hey, dude, quick question: Could you draw me an 'Ultrasauros' brachiosaur, just for old times sake?

To be honest, I love the shit out of Jurassic diplodocids.
SpinoInWonderland's avatar
Same with me  ;)

I find them much interesting than those overrated Cretaceous titanosaurs.

TBH, I think the Jurassic is more epic than people give it credit for. The giant sauropods were by far the most excellent animals in the period, as they were just more graceful and interesting than those Cretaceous titanosaurs. The stupendous marine reptiles from both the Early and Late Jurassic are also something to cheer about.

The theropods from both the Jurassic and the Cretaceous were equally badass, interesting, and charming in their own ways.

So far, the only feature from the Cretaceous that REALLY appeals to me is the menagerie of large pterosaurs that soared through the skies at the time.

Uummm,… (also see the link in the article and comments discussing). You have any opinion of the longest neck known to science?

I've seen it and the SVP abstract.

Once again, I say: "Eat your hearts out, overrated Cretaceous titanosaurs."

Indeed :D. I'm definitely surprised it was Barosaurus that finally broke the record though. I was expecting some huge brachiosaur, apatosaurus or even a rediscovered Amphicoelias to do the blow, but it came from where I least expected it. It was one of my favourite dinosaurs as a child and yet now we have verifiable evidence that it easily surpassed most if not all titanosaurs in mass. At least as far as we know. Also, how much did 'regular' Barosaurus weigh? Or is there no consensus yet? I've seen estimates range from as low as 11.9 tonnes (which probably involved shrink wrapping etc) or as high as 25 (which also seems unfeasible). If this giant one is exactly double the size, it should be 8 times as massive, so a mass calculation would be pretty useful. I've only seen one reconstruction of the giant one so far too. Didn't know you'd already seen it.

Amazing colour scheme!

Supersaurus vivianae, or as ScottHartman wrote: "Something Super this way comes". I'm not a big fan of diplodocids, but their whip tail is always fascinating. Someone needs to draw a diplodocid doing damage on a carnivore with it's tail. It's usually a stegosaur or ankylosaur on a picture doing that with their tail.

They can't get any bigger :o

Or they can ? :D
How Many Fingers Atlascopcosaurus Loadsi Have At Each Arms? I Need It For My Project

I just replied to this question in my profile page. 5 fingers, with the last two digits being quite stubby.
I posted a skeletal of a bipedal ornithopod to see what the hands would have been like.
