_Gallimimus_ was named because the anterior cervical vertebrae resembled those
of gallinaceous birds. So in actual fact _Gallimimus_ wasn't all that
'chicken-like'; only one particular anatomical feature invited comparison with
a modern bird, rather than the entire morphology. (The same rationale was
behind the name _Pelecanimimus_, and _Ornithomimus_ to a degree).
But you raise a good point, Dann. Those modern birds that look like extinct
theropods (or other archosaurs) are just johnny-come-latelies. Fossil forms
that show an uncanny resemblance to modern long-legged ratites (ornithomimids,
shuvosaurs, and... maybe another) were around long before the ratites. So
who's the real "mimic", eh?
