According to the Linnaean system, yes. The ornithischian pelvis is only
superficially bird-like, so the name is a misnomer.
Under the increasingly popular cladistic system (which I would guess that
more people on this list, and perhaps in the profession, use), birds *are*
saurischians! (And Saurischia is not an Order -- cladistics doesn't use
absolute ranks higher than Genus.) The situation becomes even more ironic
