:o indeed! This heterodox hypothesis has come up before. It proposes that the elongated, ribbon-like rectrices of certain primitive birds reperesent an intermediate stage in feather evolution. The alternative hypothesis (which is much better supported) holds that this particular feather morphology is highly derived, and has nothing to do with the origin of feathers, or of flight. It might help to add that the _Paraprotopteryx_ paper cites Feduccia's _The Origin and Evolution of Birds_ in support of the former hypothesis.

Somene can provide a pdf copy even to me, please?

Many thanks!
