They can when they have skeletal remains; you can tell alot about how they looked just from that. Combine that with several other of the same skeletons in the same area....it becomes pretty clear (at least to me). LOL....aggressive plant eaters...ever hear of Mad Cow Disease? Now THERE'S an angry vegetarian!

How do we know that was an umblical cord and they birthed live with the cord like that? maybe that served some other pre-birth function. After all if we looked at a human fetus that would be developing in the early stages, there would parts that we wouldn't be able to discern what was going on, relying completely on fossils to determine that just makes me wonder a little. Now realize I am not trying to poke holes in this or be critical, just my opinion and things I have wondered about different times.

Valid point, this could very well be a jumping of the gun to encourage people with deep pockets to shell out more research dollars. I don't know.
