Greg Paul's running pose seems to have become the standard posture for skeletals of dinosaurs, and although I don't particularly like it, I've got no real gripes with it, and that's not what I'm going to complain about.
It's his posing of pterosaurs that worries me - the wings up, one foot pushing-off pose. A lot of people have followed his lead on this, so I think it's important to point out that it's probably wrong. Pterosaurs did not
launch like that, they almost certainly launched quadrupedally, with the hand being the last thing to leave the ground. This was Jim Cunningham's idea originally, but others have picked up on it. There's one paper out (I think it's in Chatterjee et al. 2004, Posture, Locomotion, and Paleoecology of Pterosaurs
. geosociety.org), and several more in the works on this.
So even though it looks cool, it's doubtful they ever struck such a pose, and hence it's not really good for skeletals. That's why I don't pose them that way, and instead always do a dorsal and lateral view, and removed the legs in the lateral view. It's not the only way it could be done, of course, but the Greg Paul-styley ones have to stop.
