PS. I actually know the researcher who discovered the fossilized soft tissue.

Cool! Ask her if she could repeat the test mentioned in post 36, only this time test it against reptile, amphibian, bird, & mammal collagen. This would provide a solid case for dinos being more related to birds than to other clades.

I'll pass the suggestion along if I get the chance. FWIW, I was told that there's another Science article coming soon that presents this latest research, so that might provide more insight and may very well already include the type of tests you recommend.
