"Feathered Dinosaur Mystery", requests, etc

[SeanSt8579@aol.com]

So I caught "The Feathered Dinosaur Mystery" on the Science channel the other 
day, and I must say, I was pleasantly surprised. Not only was there no 
"counterpoint" by the Feducciaries (as I was expecting), but they got into some 
of 
the actual research behind Prum and Brush's model (talked a little about Harris 
et al 2002, although they probably could have explained its significance a 
bit better). Cool animation of M. gui proudly gliding about too!

Annnnd...anyone have PDF copies of the following?:

Xu et al. 2003. Pygostyle-like structure from Beipiaosaurus (Theropoda, 
Therizinosauroidea) from the Lower Cretaceous Yixian Formation of Liaoning

Xu & and Wang. 2003. A new maniroptoran dinosaur from the Early Cretaceous 
Yixian Formation of Western Liaoning

Zhou & Zhang. 2002. Jeholornis compared to Archaeopteryx, with a new 
understanding of the earliest avian evolution.

If anyone could forward me any/all of these, i'd love them forever.
