Re: New alvarezsaurid

<<Oh well, it looks like another nail in BCF's coffin.>>

<I don't see how that's so... BCF says that the lineage from basal
dinosaurs to modern birds were small, arboreal/scansorial creatures that 
spit off larger terrestrial lineages, right? Alvarezsaurids would just 
be another one of these lineages.>

And why they could _not_ be the antecendants I don't know, but 
*Shuvuuia* seems to be the first to have a prokinetic snout, and while 
this may be novel and still the first appearance of this character that 
led on to other lineages (Euaves, for example) it still asserts 
theropods were the ancestors of birds.

But like I said on the other *Shuvuuia* post I sent today, I'll not 
state yea or nay to BCF---or BADD, etc..
