Three theories about the origin of flight in pterosaurs have been proposed: 1) the arboreal parachuting theory (passive falling from trees leading to gliding and eventually to powered flight); 2) the cursorial theory (bipedal running and leaping leading directly to powered flight); and 3) the arboreal leaping theory (active leaping between branches and trees leading to powered flight). The available evidence as to the functional morphology of pterosaurs, and in particular their hindlimb, is reviewed and used to test the three theories. Pterosaurs were well suited for arboreality and their hindlimb morphology argues against cursoriality, but supports an arboreal leaping lifestyle for early pterosaurs or their immediate ancestors. |
