No one is saying bipedality "just happened."  Archosaurians have more
powerful hindlimbs than forelimbs.  Perhaps bipedality could evolve under
various pressures to run faster by getting the forelimbs out of the way,
hence the more reduced forelimbs of the early dinosaurs.

Which brings to mind the dilemma...if theropods were developing bipedality
in order to run faster, why would they develope feathers on the arms, or
larger arms for that matter. It seems this would tend to slow them down!
