Re: bipedality in pterosaurs (was:climbing dromaeosaurs and friends)
Quetzalcoatlus species is extremely well preserved, and seemingly quadrupedal.
limited flexibility in the neck would make bipedality virtually impossible due
problems. When assembled to the torso, the bones of the arm and leg articulate
standard quadrupedal stance. Also, Qn doesn't appear to have wing power enough
from a bipedal stance, but does have sufficient total power for quadrupedal
in a dead calm.
