A while back I started a project in which I would reconstruct an ancient animal layer by layer, moving from various organ systems using some degrees of inference to make sure these organs are correctly aligned, and perhaps correctly sized. Based on work I was already doing, I chose an oviraptorosaur, and because it deserves more attention, the subject would be “Ingenia” yanshini. Now, as I’ve said before, there are a few problems with what, precisely, is “Ingenia” yanshini. It seems, though, that this is a long-legged, short-armed and giant-thumbed animal that would have resembled Nemegtomaia barsboldi, a crested oviraptorid; enough that common referral of ZPAL MgD-I/95 or “Ingenia” yanshini (as with Greg Paul’s various paleo books) has fallen to the wayside, and Kundrát & Janáček (2007) referred it to Comchoraptor gracilis.
This reconstruction proceeded outward in, with the body, the plumage, and the skeleton, and then further inward with the organs. The pulmonary system was tricky, as it forms an intricate layering in itself. And this was all done in pen and ink. Behold:
