The Coconino Sandstone has been assumed to be formed from ancient desert sand dunes. Within this rock layer, we find 4-footed animal tracks. Scientists did experimentation on how the tracks may have been formed and notice what has been discovered about the trackways:
“A detailed statistical analysis of these data led to the conclusion, with a high degree of probability that the fossil tracks must have been made underwater… [Regarding the fossils] Toe imprints were generally distinct, whereas the prints of the soles were indistinct. These and other details were present in over 80% of the fossil, underwater and wet sand tracks, but less than 12% of the dry sand and damp sand tracks had any toe marks. Dry sand uphill tracks were usually just depressions, with no details…”
“…Furthermore, these tracks often show that the animals were moving in one direction while their feet were pointing in a different direction. It would appear that the animals were walking in a current of water, not air. Other trackways start or stop abruptly, with no sign that the animals’ missing tracks were covered by some disturbance such as shifting sediments. It appears that these animals simply swam away from the sediment.”
This evidence fits the worldwide flood perspective.
