RE: Postosuchus posture
According to Weinbaum (2002), it "was at least facultatively bipedal, and
possibly an obligate biped." I saw his talk, and indeed, the manus is tiny.
Note the original reconstructions based on Chatterjee's work are
chimaerical (including Shuvosaurus elements, I believe).

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
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
of speed, as in dispatching prey?
