RE: New-ish Papers

Jerald Harris mentions:
Liu, Y., Liu, Y., and Zhang, H. 2006. LA-ICPMS zircon U-Pb dating in the
Jurassic Daohugou Beds and correlative strata in Ningcheng of Inner
Mongolia. Acta Geologica Sinica (English Edition) 80(5):733-742.

(From abstract):
"The Daohugou beds were formed in the geological age of 164-158 Ma of the
middle-late Jurassic."

If this sticks, then _Epidendrosaurus_, _Pedopenna_, and _Jinfengopteryx_
predate _Archaeopteryx_.  No "temporal paradox" here!
