Re: Neovenatoridae and Megaraptora: now it can be told!

 Tim Williams and myself have suggested the possibility *Rapator*
 repr= esents a pdI-1 phalanx of an alvarezsaurian (possibly a
 mononykid=2C based = on morphology=2C but this is even more
 far-fetched due to biogeography reas= ons).

A mononykine would be far-fetched, but an alvarezsaurid in general would not be -- South America and Australia weren't isolated from each other.
