You better dump your cited study, because that is all they have done.
"1. Yes, we know that "all had something to say about Sinosauropteryx."
However, they were smart enough to realize visual analysis does NOT qualify as conclusive evidence."
As I pointed out in the posts below, other scientists have criticized this study for being nothing more than pointing at pictures and saying, "I think these are collagenous tissue, cuz I've seen it before." Their study is far from conclusive, even though they have been quite forceful and nasty about having the final word. They seemed to miss quite a bit of analysis that they fault other scientists for.
