Re: Interpretation
Quite so. I don't mean to imply that Archaeopteryx, for example, is a direct ancestor of modern birds. Even if it was, we wouldn't know it.

(Actually, I'm of the opinion that it almost certainly wasn't, because it has no uncinate processes on its ribs.)

Re: Interpretation
If you take away the feathers, it takes an expert to distinguish between the dinosaur Compsognathus and the bird Archaeopteryx.

I think the forelimbs are a bit of a giveaway. But apart from that, yes.
