Description
2014's other ''largest ever'' titanosaur, albeit Patagotitan didn't have a name yet. Also a wonderfully complete animal (I'm not sure which of the two preserves a larger % of the skeleton, but the record in a single individual must be Dreadnoughtus's). Multiple sources have explained why the original mass estimate wouldn't work, notably Paul (2014) and Bates et al. (2015); a common mistake in reconstructions is to restore the torso as much too long, either based on the 3D model (which has the dorsal vertebrae disarticulated) or on the original paper skeletal, I'm not sure. Since the type was not skeletally mature, maybe adults would've reached the 26m estimate?References:

Yeah, no estimates so far, unfortunately.

That's a really massive neck. And the vertebrae look massive accordingly.
I can't help but wonder if at least some sauropods could have delivered powerful blows to each other with the top of their necks. Not with the ventral surface (with the exception of apatosaurines) or the lateral surface, but with the dorsal surface of the neck. I envisioning it looking like necking behavior in giraffes, except they're hitting each other with the top of the neck itself, not the skull (sauropod skulls are definitely not built for that). I dunno.

I love that short body, the thick legs and the long, massive neck.
Still, I have the same question as with some other skeletals I have seen. Why is the neck in your version only about 9 m. long? It was originally estimated at over 11 m.

Thanks!
Only one cervical is preserved in Dreadnoughtus, I reconstructed the length based on the neck of Malawisaurus. I believe the paper's authors used Futalognkosaurus.

Did you restore it as a 9th or a 10th cervical? Scott Hartman got a smaller neck length cause he restored it as a 10th cervical.

I believe it was as a 9th, but I'm not sure.

Did you take cartilage thickness into account when you made this extremely short dorsal column?

It is probably the most accurate skeletal on the internet. Could I use it as a reference for an artwork?

Sure, just keep in mind I'll probably be updating it soon (looking at it now, the neck posture and soft tissue look kind of awkward).
But me getting dissatisfied and making a minor update happens all the time to my skeletals, so that's normal.

It doesn't really matter cause I make my drawings on pencil. I only use skeletals as guides for proportions.
Just to know, I have already used some skeletals of yours in the past. I just haven't posted the drawings.

Will you make a Paralititan skeletal/schematic someday?

I've tried before and the file got corrupted, maybe I'll redo it.

Really? It doesn't even crack 30 tonnes? That's odd.

Only 27,000 kg? That's... a lot less than I expected, but it does sound more reasonable than some estimates

Wow, so not even reaching the size of my boi Giraffatitan ?

rip
It can reach HMN SII, but that's about it.

Well to be fair , HMN SII is plenty big......

Oh my god accurate torso and head size and accurate mass. Instafav.

Dang, 27 tonnes? Wasn't this guy 50 tonnes or so?

I could see 30, but 40 and up is pushing it.

You're welcome! Are we getting Notocolossus soon? Very few quality skeletals of that one.
👍: 0 ⏩: 1
Probably not, Notocolossus is... strange. And fragmentary, so it'd look a lot like my Patagotitan.
Perhaps a schematic in the future though.
👍: 0 ⏩: 1
I thought it would look more like Dreadnoughtus.
👍: 0 ⏩: 1
Nah, Notocolossus is a lognkosaur or a close relative, while Dreadnoughtus isn't.

How do those comparibly little legs hold up that monster of a neck...dinosaurs are puzzling..
👍: 0 ⏩: 3
Because their legs are sturdy and columnar with their neck vertebrae being pneumatic making it proportionately lighter than one would initially think.
👍: 0 ⏩: 1
Yeah, the other answers are right. Still looks crazy, though.
👍: 0 ⏩: 1
That's a common question...
The neck isn't quite as heavy as it seems. The bones are very low-density. Also, most of the animal's body mass is in the torso, so it doesn't take much effort to hold that neck.
👍: 0 ⏩: 1
So it doesn't even get to 30 metric tons, poor thing keeps getting downsized. It was still a neat discovery due to it's completeness, though...
👍: 0 ⏩: 2
At least there's still the possibility that the mature ones would have weighed ~40-45t.
