Sauroposeidon painting
...with Acrocanthosaurus (contemporaneous) and Homo sapiens (non-contemporaneous) for scale.

Edit: Forgot to mention I use Scott Hartman's ( skeletal for reference for the Acrocanthosaurus.
Sauroposeidon multiview skeletal
Well, I finally finished this. I agree with D'Emic et al (2012) that Paluxysaurus is really the same as Sauroposeidon, and so offer a composite restoration here. The Sauroposeidon material from the holotype is only cervicals 5-8. The overlapping cervicals in Paluxysaurus are nearly identical, when accounting for size, ontogeny and individual variation (the Paluxysaurus material is only about 60% the size of Sauroposeidon). Recent phylogenetic work by D'Emic and others consistently show the two as sister taxa, and also consistently as non-brachiosaurid somphospondylan titanosauriformes. The largest individuals are probably about 30% smaller than the largest titanosaurs, so Sauroposeidon is probably no longer in the top ten list of largest sauropod taxa (and maybe not even in the top 20).

In the above reconstruction, only the lateral (side-view) is done 'rigorously' (exception: dorsal view of ilia/sacrum is rigorous as well), with non-preserved or undescribed/non-photographed material with grey fill and preserved/photographed material in white. Scale bar is 1 meter.

Edit [updated 8/27/17]: Made some updates to the scaling of the forelimbs, per suggestions by Steveoc and to the soft tissue outline per suggestions by ijreid.

Due to recent new events, this hypothesis has come up again. My initial thoughts over at my (mostly dormant) blog,  Part 1 of 2:…

I welcome comments as always, but would prefer them over there than over here. :)

Your skeletal reconstructions have that rare organic quality that is so often lacking in scientific illustrations of their kind. Fantastic work.

Thanks for noticing, it's much appreciated!

Zach, I'm currently writing a paper on what I believe is a new Titanosaur (yay!) that I want to get published into PeerJ, and I need two reviewers. Would you like to be one? I've already come up with the name, entered it into Zoobank, and wrote out most of the paper's base already. The specimen isn't all too impressive, but I think it's worthy enough of a new genus. Besides, you could always end up being a co-author if it helps you get your name out there.

Unfortunately, I do not have a lot of spare time at present, so not sure I could provide a formal review, but if you intend to submit it to the preprints, I would be willing to make some short comments at that time. Same issue with co-authoring, unfortunately do not have much time for that either. It would depend on what exact kind of involvement would be needed.

Oh, that's okay. I plan on a full published peer-reviewed article. Do you know anyone else who would be willing to review for me (I've already contacted Nima, so anyone else)?
palaeozoologist Featured By Owner May 29, 2016  Hobbyist General Artist
I know that anyone I would suggest are also quite busy, so I'm afraid I'm not of much help. Sorry :(
