Re: New Oldest Bird?



No, Xu and Zhang found that it was less closely related to birds than
Archaeopteryx or scansoriopterygids, because of its unreversed hallux and
short toes.  Of course, Middleton's work suggests Archaeopteryx lacked a
reversed hallux too, and scansoriopterygid remains seem equivocal when one
considers the need to examine metatarsal torsion instead of just apparent
hallux orientation.

Not to mention the fact that scansoriopterygids have short toes as well (in spite of one of the reconstructions in the *Scansoriopteryx* paper).
