Excuse me (to whoever posted the above), but I find this message very
confusing.  Are you drawing your conclusions about posture based on the
prints (IOW are you fully convinced that these are pterosaur prints), or
from the anatomy of the animals (IOW, again, are your conclusions, in your
opinion, valid even if the prints are not pterosaurian?
