Natural Science 301 Guidelines
This is an open forum area for all members for discussions on all issues of science and origins. This area will and does get volatile at times, but we ask that it be kept to a dull roar, and moderators will intervene to keep the peace if necessary. This means obvious trolling and flaming that becomes a problem will be dealt with, and you might find yourself in the doghouse.
As usual, Tweb rules apply. If you haven't read them now would be a good time.

I found an article on fossils of the earliest known tetrapods, but I did not care for the reference, and I am looking for something better. Nonetheless, the fossils for aquatic and land dwelling tetrapods are being found older than previously.Glendower: I can call spirits from the vasty deep.

It probably should be noted that further research is indicating that the tetrapod tracks found in Poland a decade ago and from around 18 million years before Tiktaalik were not made by a tetrapod but are instead thought to have been imprints of a fish feeding in a circular pattern or maybe the remains of "fish nests."
Similarly a supposed trackway found in Pennsylvania are thought to be impressions left by fish poop.

I do not know how to show the pictures here, so anyone who knows can add the pictures.Glendower: I can call spirits from the vasty deep.

Trackways and burrows excavated in situ from the Shibantan Member,
Dengying Formation, China: (A and B) epirelief (top bedding surface) and
hyporelief (bottom bedding surface), respectively; trackways (TW1 and TW2)
and undermat burrows (UB1 to UB3) are labeled; (C) latex mold of (B),
with trackways and burrows marked and labeled; (D) enlargement of rectangle
in (B), showing connection between TW2 and UB3 (marked). Scale bars – 2 cm.
