Re: pteros have lift-off
Greg Paul in dinos of the air suggested that Archaeopteryx and other birdy

and tree-climbing. Is this the general consensus?
Can the same be said of pterosaurs? Or did terrestrial take-off somehow
encourage longer antebrachia?
Also, did basal short-metacarpal pterosaurs create a Z-fold in the forelimb?
And finally, what was that maximum carpal angle? and did it fold medially,
laterally, or posteriorly?
PS thoughts below.

Then why does every big bird launch I've ever seen include it?
It seems like a good way to accelerate AND fly. Such a system requires a less

And with ground effect acceleration, it doesn't need to. That's the point, I
