quadrupedal dinosaur palms

["meor hakif" <hakif@hotmail.com>]

Previously their was some discussion on the palms in position of theropod 
dinosaurs' manus . I was wondering, if theropods palms faced inwards and the 
radius and ulna could not cross , what about the manus of quadrupedal 
dinosaurs...All reconstructions show that their hands were not in the palms 
in position, but the palms faced the posterior... is this correct?...and 
when did this change happen...or maybe the bending of the elbow into a semi 
sprawling gait made this position possible....?
