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

Edit: Forgot to mention I use Scott Hartman's (www.skeletaldrawing.com/) skeletal for reference for the Acrocanthosaurus.

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.
