Too many illustrations show the leg straight down so that only half the
body (left or right side) is supported by the leg. Guess there must be
an
antigravity pack on the other side. Watch an ostrich or emu walking for
example.
Though... in birds, the hip joints lie far apart, while in
tyrannosauroids they touched the [...] vertebral column, so this effect,
while
unavoidable, must have been much smaller in *Tyrannosaurus* than in
ostriches or emus.
Then HP John Scanlon sent me a photo of an emu pelvis. It's just as
narrow. Emus -- and I think ostriches, too -- are exceptions among birds
and therefore fit the example pretty well, it appears.
