Re: Archaeopteryx paper in Naturwissenschaften online

What phylogenetic evidence is there that _Archaeopteryx_ was arboreal? Come to think of it, what the heck does phylogeny have to do with _A_'s arboreality?

Phugoid gliding

Do I want to even know where the term "phugoid" derives from? Anyway, I'd have to say that _A_ hardly seems comparable to a squirrel. Has anyone determined if there is any advantage (more efficient?) to arboreal upwards leaping (as put forth by Paul 1988), aside from getting higher?
