My guess is that the early artists were still  utilizing Marsh's 
reconstruction:

Knight's Field museum mural shows this as well as Zallinger's Yale Peabody 
mural  (which is very extreme). Oddly, Knight's earlier AMNH 8-Spike painting 
and his  AMNH sculpture correct this somewhat. As far as pose goes (ignoring 
plates and  spikes) Lull's model is very modern. If you have Colbert's 
_Dinosaurs: Their  Discovery and Their World_, there is a photo layout of these 
old  
restorations.
The pectoral girdle in dinosaurs is very  difficult and some errors in 
assembling skeletons are still being made. Perhaps  Kent Stevens or Ken 
Carpenter 
(if he's still here) have something to say about  it. DV
