Like I said, nothing but opinion. Conversely...According to Whitmore's reports, the deposit interfingers with other formations of unquestionable marine origin, implying that the Coconino is also marine. It bears fossil trackways and burrows best understood as being related to underwater activity, not to a dry, sand dune environment. Its sand grains are poorly sorted and somewhat angular, not at all like desert sands with well-sorted and rounded grains. We suspect the research will demonstrate that the sand dune interpretation can be confidently rejected in favor of a better supported sub-aqueous interpretation. ref
Leonard Brand,13 who has done the most field work on these footprints, has also done laboratory studies of salamanders walking on various types of sand—dry, wet, and underwater. The experimental tracks that best matched the Coconino tracks were made underwater. Flowing water would also explain the sudden appearance and disappearance of many tracks, as the currents picked up animals and they landed in new places. ref
One of the most common observations is that the tracks have bulges or sand crescents on one side, thereby proving that they were made on inclined surfaces. (Lockley and Hunt 1995).
Tracks showing possible loping, running, and galloping gaits are found throughout the Coconino Sandstone. These can only have been made on dry land.
Tracks of small arthropods, attributable to spiders, centipedes, millipedes, and scorpions, occur abundantly in the Coconino Sandstone. (Schur [2000] has some excellent pictures.) Some of these trackways can only be made on completely dry sand.
Raindrop impressions also appear.
Not to mention the previous link I provided in detail the foot prints as well as how terrestrial sandstone and marine sandstone deposits are easily distinguishable.
