I have a few hunches about dinosaurs;

1-) I'm thinking that the thick necks of large theropods supported far more muscle and meat than commonly imagined.

2-) I imagine that most dinosaurs, especially the "reptilian" ones, bore elaborate skin flaps and display structures on their heads. I have no evidence for this, but look at just about any living animal, and then see their skeletons. There's far more to soft tissue than most reconstructions admit.

3-) Dinosaurs, like real animals, sustained injuries throughout their lifetimes. (look at the hand!)

4-) Some dinosaurs may have had their upper leg "buried" inside their bodies. This is the case with most birds and mammals today.

All these "hunches" have been realized in this fun drawing.

Very cool work here. I imagine that large theropods expressed as much variation (even in similarly-shaped forms) as there is between a lion and a tiger. Even though their skeletal details are nigh-identical, they look very different and distinctive in real life. This Torvosaurus, though it is a stand-alone piece, could be accompanied by related forms (megalosaurs) to illustrate this kind of variety.

I agree with you, and I really need All Yesterdays book!

This is good work. I'd like to see your take on Spinosaurus because of this.

Very cool! I like thinking of birds of paradise; we wouldn't know of the outlandish displays they have if we had only skeletons; dinosaurs had to be the same.

Imagine what weird displays dinosaurs must have had...

I largely agree with everything you're saying here. We are probably missing a lot of important soft-tissue details that would have made the species recognizable in real life. I'm immediately reminded of the possible Tarbosaurus wattle.

I've mused about the contours of the upper leg as well. However, birds don't move their femurs to the extent that at least some non-avian dinosaurs would have, and in some mammals the hind leg is clearly distinct from the torso, so I'm not sure what would be the closest match to dinosaurs. I've been trying to find some kind of a realistic middle ground myself, but I really wish there was a way to know what it really looked like.

About the injuries though, usually paleoillustrations are used to showcase the typical anatomy of a taxon, and throwing in too extensive injuries can sabotage that information content somewhat. Even though I imagine some abelisaurs and maybe tyrannosaurs as well lost their tiny arms in intraspecific combat, I think there's good reason to illustrate them with both, unless you mean to draw attention to that detail.

The upper leg is a complicated issue - perhaps how visible it was varied within families, and even in single species (as in fat vs. thin)
I generally don't agree with reconstructions that show the leg separate until the top of the hip, but then again "burying" eerything doesn't seem to be right either.

About injuries, one should also look into tumors, (like these poor devils, [link]) or broken-healed bones, especially in the tail region. Of course, I agree that these should be omitted in species-descriptive illustrations.

Absolutely agree about the skin appendages, been thinking the same myself, look at the majority of large birds - Turkeys, Emu, Cassowary, Ibis etc. Lots of Wattles, combs, coloured skin patches, all sorts of weird stuff going on, simply putting skin over the bones just can't be correct. Of course the alternative is to guess which would be likely just as wrong, but certain educated guesses can be made about colours, and who knows, maybe one they'll find a T-rex with fossilised skin impressions of Wattles and skin and beaks etc, even fossilised pigments are possible, and more Fossils are being uncovered now than ever before

I guess a majority of dinos were actually quite bland - but every once often there must have been some quite spectacularly weird ones.

Any dinosaur is only as bland as a paleoartist reconstructs it to be. ;)
