These are all quite impressive. I am embarking on a project, illustrating all of the Nemegt Formation dinosaurs, and your oviraptorsaur skeletals are a treasure trove and a relief... I was dreading having to wing it and risk severe anatomical inconsistencies with my restorations. But concerning the Opisthocoelicaudia... Is it indeed distinct from Nemegtosaurus? The fact that we have a skull and a postcranial skeleton known from the same formation and they're classified as unique genera? It seems a bit off to me.

So far, the reasoning for it being distinct is based on the presence of a distinct skeletal type known for nemegtosaur-like skulls in Rapetosaurus krausei, from Late Cretaceous Madagascar. Morphological differences abound between the two types of postcranial skeletals, making it more difficult to assume the skull of Nemegtosaurus mongoliensis and the body of Opisthocoelicaudia skarzynskii come from the same animal.

So what would be the safest route to take, reconstructing the head of Opisthocoelicaudia?

If we had the skull of a saltasaurine, it would look like that.

Wouldn't an antarctosaurid be a better parallel?

Consider right now that finer relationships of titanosaurians are loose, but when you get closer to Saltasaurus, they've become more refined. The low-spined, wiiiiide-hipped, small titanosaurians of the Saltasaurinae (or Titanosaurinae, depending on your tastes) include Opisthocoelicaudia, but not taxa like Antarctosaurus or the like, including Huabeisaurus, which are distinct in their vertebrae from Opistho and other saltasaurines. The distinction between skulls of nemegtosaurids and whatever animal the jaw of Antarctosaurus wichmannianus belongs to (if it belongs to the same postcrania) imply that one cannot just use any skull type to ascribe to something like Saltasaurus or Opisthocoelicaudia.

I'll just have to wing it, then?

Yeah ... just whatever it ... you could even make up your own model, although being conservative and just making a "general sauropod" skull might work.
