Vertebral mobility

[David Krentz <ddkrentz@charter.net>]

  Are there any comprehensive studies on the range of mobility or  
dinosaur necks, backs and tails?  I was recently chastised by an  
extremely learned man for actually slightly curving a tail on one of  
my sculptures, as well as other notes that would have simply left my  
pose as stiff as a pole.  I try to pay close attention to these  
things and I take all research seriously, but I just found some of  
the comments extremely conservative.
I am aware of the dinomorph project, and was wondering if such a  
study was done for entire vertebral columns for various types of  
dinosaurs. I'd like to know degrees of rotation in all planes.
