Some people think Avimimus is a chimera (an oviraptorosaur skull, bird
vertebrae, an elmisaurid [or Mononykus!] hind limb, and so on). Others
think its legit. It does have some very oviraptorosaur-like features, and
it is also very "birdy" in others.

Actually, Russell & Russell consider them chalicothere-analogs. I consider
them megathere-analogs. Of course, since we don't have modern
chalicotheres or megatheres, this doesn't help too much...
