Re: pteros have lift-off

I don't think you've examined the power required to do that. The pterosaurs I've looked at don't have it.

I'm curious as to what you and Jim say about wing clearance when bipedal. Seems to me to be no problem if a pterosaur deploys its wings while standing on two legs, then either leaping with hind limbs, like a bird, or running to take-off speed, like other birds.
