Hm. In modern animals, bipedality is presumably mostly associated with
being a bird. Birds are about all bipedal, mammals and lissamphibians
mostly quadrupedal, lizards are mostly quadrupedal or snakes. Looks
like phylogeny swamps function here.

Might be different if we look at, say, Triassic-Jurassic archosaurs.
