Re: ptero endothermy



But that hypothesis doesn't impact the fact that the ilia can help
provide area to accept wingloads that reach the torso, and that longer
length, or larger diameter can reduce the attachment stresses.  This
would seem to be true no matter what the origin of the wings might be.
