Art, there is still one thing that is certain. The animal cannot make
tracks if the water is 100 feet deep. No way. Not unless you have a lizard
with 100 foot long legs.
For those who might not know, Brand has suggested that the tracks in the
Coconino were produced by animals which were partially floating with only
their back legs on the surface. (Even if that were true, the flood waters
Brand wants couldn't be any deeper than the length of the animal) Brand
cited tracks which changed direction suddenly and which had feet pointing
uphill but the animal moved perpendicular to the direction the feet pointed.
Brand suggested that this was due to a current carrying the animal along
while his back feet kept hitting the ground. There are many problems with this.
1. there are scorpion and spider tracks. Since these are shorter than the
lizards, it is unexplained how the arthropod tracks were laid down.
1 a. Scorpions leave a different track depending on the temperature. At
high temperature they use fewer feet to touch the ground. We find high
temperature scorpion tracks.
2. animals have been observed today walking across the dunes with feet
pointing uphill but moving perpendicular to that, Lockley and Hunt state,
"Trackways found in fossil sand dune deposits have generated
much interest over the years. One of the most common
observations is that the tracks often have bulges or sand
crescents on one side, thereby proving that they were made [p.
42]on inclined surfaces. Typically these sand crescents--also
sometimes referred to as impact rims--are situated behind the
rear or 'heel' of footprints, showing that the animals were
progressing upslope. It seems that this type of upslope trackway
is the most common and usually the best preserved. Even so,
trackways that indicate downslope progression are also known, as
are a number that show sideways or oblique movment across dune
faces. These sideways or transverse trackways are especially
interesting because the tracks often point upslope while the
trackway crosses the slop horizontally or obliquely. There is,
however a modern analog. We have observed fresh trackways of
lizards with tail drag marks, that run transversely across dune
faces, leaving individual tracks that point uphill." Lockley and Hunt,
