Re: Oldest Live-Birth Fossil Found; Fish Had Umblical Cord
no offense, but I am just not totally sold on that. I think it is cool to see the embryonic fish fossilized with the mother's skeleton, but maybe the whole umbilical cord isn't quite what they think it is. Now granted I am not a scientist, but I just always wonder at the whole theory thing when dealing with species that we cannot observe first hand.
For example, this dinosaur is aggressive and hunted in packs. This one was docile and ate plants. Well, maybe they did eat plants, but how do we know they were docile? There are things that I believe we can discern due to physical evidence, but too much of the behavior stuff really can only be an educated guess.
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.

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!

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.
