What is the correct position for the arms and hands
of animals such as Caudipteryx or Sinosauropteryx?
If the radius and ulna of these animals could not
cross then surely the birdlike posture with the arms tucked back is not
possible.
Which leads me to ask whether birds can cross their
radius and ulna to create rotational wing motion during flight, or to fold them
away.
