Re: Alvarezsaurs/Ornithomimosaurs (was Re: T. bataar)




Nick,
Well Patagonychus is a nice intermediate between "something" and mononykines, but I'm not convinced that Alvarezsaurus is that "something".
Seems to me it would be more prudent to put Patagonychus in a Family Mononykidae, and obviously Alvarezsaurus goes in Alvarezsauridae.
Two separate families, two separate OTUs----at least until we have more of an Alvarezsaurus skeleton to work with. In my opinion somebody really jumped the gun in dumping these all into one family, which is something a "lumper" like me rarely says.

Apparently not, as _Patagonykus_ is said to be a nice intermediate between
_Alvarezsaurus_ and Mononykinae (but not particularly ornithomimid-like).
