One interesting aspect that I can point out, other than the general uniform appearance given to Plateosaurus by many different artists, is that the hand is well rendered in each and every image I have found. Facial reconstruction is done brilliantly by the artists as well, of course, but the hand, with all of its fine motor skills comes across in even the illustrations as possessing these finer motor skills. In Raul Martin's work (I can never seem to get a hold of him to discuss his work so apologies sir if you stumble across this on the internet) the hand is shown as clearly aiding in the mobility of Plateosaurus, yet it is still flexible enough that you can completely discern the range of motion needed for grasping with the clawed fingers. The middle portrait is a bit harder to draw taht conclusion with, though not so bad as to be completely wrong. The illustration below does the best job of showing the flexible fingers, even if it is a little bit of a fantasy.
