Re: pteros have lift-off

Actually, we did it for the TMM replica by the rather unscientific method of 
averaging the allometric lengths of the humerus and r/u, which gave us a 
number on the approximate order of 2.05.  One of the reasons that we've 
continually reiterated that that replica is intended for viewing, not 
scientific research.  So, no -- it wasn't isometric, though 2.05 is within 
5%.  The Qn torso depth ratio is different -- it is controlled by the dp 
ratio due to the precise relationship between the dp crest and the coracoid 
flange.  Remember that with the exclusion of the wing, I was the one who 
generated the long bone dimensions used to construct the missing bits of 
the TMM replica, so whether they're right or wrong -- I know exactly how 
they were developed.
