No, they found fuzz, and as I said before China was the only place they found it.
1) Fuzz should have a period after it. It's the end of one thought, and a new one begins after it. -1
2) Before should have a comma after it. -1
You people are grasping for straws.
People grasp at straws, not for them. -1
You are of course unwilling to consider the fact that the fuzzy imprints were only found in China could be, and probably is, attributable to unique aspects of the soil in that area, because you desperately wish to believe that there is a link between dinosaurs and birds.
1) Comma after You are. If you were speaking it, you would have paused there. Also, after of course. -2
2) This is a huge, run on sentence. You should have broken it at area. The next sentence should have started "This is because, etc." -1
You are not being logical, you are simply creating your own origin myths as you go.
Or, it could be because we're looking at the evidence, and finding logical conclusions based on that evidence.
Overall, you rate a -6 on my grammar scale. Please learn to proofread better. A refresher course in English Composition wouldn't be amiss, either.
