Trackway with at least four steps.
The top of the Springdale Sandstone, which was deposited in a fluvial channel, preserves a megatracksite that can be traced extensively from southwestern Utah, as far east as Ward Terrace near Tuba City in north-central Arizona. The interpretation of the “Springdale megatracksite” (Lucas et al. 2005a),supported by several authors (DeBlieux et al.)
Is this a skin impression? The tracks are mostly underprints, this is within a larger track. The overlieing bed is not preserved here, It would interesting to find the contact at other Springdale Sandstone sites and see if the overlieing beds dip into the tracks, and to see if the prints are from the overlieing beds.
