Re: Ah ha! That's where therizinosaurs came from



This only applies to powered flight, though. Someone earlier brought
up the Kakapo, which climbs trees and glides to the ground. This form
of launch is obviously different from ground-based launching in
powered fliers and requires at least some degree of arboreality.
