@sonichell,
There is a paper by King and Shubin that questions the "tetrapod" hypothesis of the earlier Devonian "Trackways" as reported by the Polish paleo team. king has done trackway studies in intertidal waters and mudflats by
Sarcopterygian fishes (lungfish etc) and has seen very similar trackways as those in the Polish paper.
So, we may have an example of how controversy in science is settled (by more data and convincing evidence)
Should the polish tetrapod be real (Of which they only had these hole like "trackways" and no specimen), whereas , with Tiktaalik, they have a specimen AND tracks (with similar indentations in the fluvial bottoms, the Polish tracks would set back a transitional form by about 10 million years. Not a real big deal but something worth settling so science can proceed with other stuff.
