Postosuchus posture
I am attempting a restoration of Teratosaurus, a close relative of
Postosuchus. I have located Gregory Paul's reconstruction of the latter
in 'The Complete Dinosaur' that displays a bipedal stance. Is this in line
with current thinking, or is a quadrapedal gait, a la 'Walking with
Dinosaurs', closer to the mark? Postosuchus's head looks too massive and its
hindlimbs too short to be an obligate biped. Could it have utilized some
combination, i.e. walking about on four legs but becoming bipedal for bursts
of speed, as in dispatching prey?
