Were early tetrapod tracks produced by walking fish?

From “A Small Step for Lungfish, a Big Step for the Evolution of Walking” (ScienceDaily, Dec. 12, 2011), we learn,
Extensive video analysis, published in the Proceedings of the National Academy of Sciences, reveal that the African lungfish can use its thin pelvic limbs to not only lift its body off the bottom surface but also propel itself forward. Both abilities were previously thought to originate in early tetrapods, the limbed original land-dwellers that appeared later than the lungfish’s ancestors.
The observation reshuffles the order of evolutionary events leading up to terrestriality, the adaptation to living on land. It also suggests that fossil tracks long believed to be the work of early tetrapods could have been produced instead by lobe-finned ancestors of the lungfish.
Walking fish are nothing new, but there’s more to terrestrial life than that.
