RE: Aves and Mononykus

[Gareth Dyke <Gareth.Dyke@bristol.ac.uk>]

>>The Nature _Shuvuuia_ paper also examines in-group relationships in
Alvarezsauridae, and finds much the same result: _Alvarezsaurus_ +
(_Patagonykus_ + (_Mononykus_ + _Shuvuuia_ + _Parvicursor_)).>>

One of the main problems with the ?monophyly of the alvarezsauridae is 
poor preservation of Alvarezsaurus - this material may prove problematic 
in future analyses - perhaps if someone were to find the skull ?
