"A fossil previously mistaken for the remains of an extinct fish turns out to hold the earliest known creature to have emerged from the Earth's waters and walk on land some 350 million years ago."
Uh huh. They were wrong the first time. How do we know they aren't wrong again? (It's all assumptions anyway - this assumption just fit their agenda better than the other.)
Good point. We don't know. And considering that this fossil has been mis-ID'd before there is a good chance that after objective peer review it will be debunked. That is the nice thing about science, questions are welcomed and in fact required before a theory is accepted by the community (scientific, that is).
