Hey, this important bit of information is many years old. The original
publication was way back in 2003. What took you so long?

Xu, X., Z. Zhou, X. Wang, X. Kuang, F. Zhang, and X. Du. 2003.
Four-winged dinosaurs from China. Nature 421:335-340.

The above url refers to a new article in PNAS

Sankar Chatterjee and R. Jack Templin, Biplane wing planform and flight
performance of the feathered dinosaur Microraptor gui, PNAS 2007; 104:
1576-1580; DOI 10.1073/pnas.0609975104

I see that now. So it was just a very poor choice of thread title. Has
Chatterjee noticed that Archaeopteryx also seems to have flight feathers
on the hind limbs?

Don't know. I have not read the whole article. It is an open access
article though; you can download a pdf.

While you're here, could I encourage you to post at least a little bit
of the article's content when you do this stuff? Take Jason Spaceman in
Talk.origins as your model.
