Possible tracks of humans, mammals, and dinosaurs were located, mapped, and studied in rocks of the Kayenta Formation at seven localities within two study sites near Tuba City, AZ. Several fossil bones, teeth, shells were located and tentatively identified as representing phytosaurs, lizards, and the mollusc genus Unio. The dinosaur prints are ascribed to Dilophosaurus and other genera. The quasihuman tracks are discussed in relation to various criteria. Each author has written his own estimation of the possible authenticity of the supposed human tracks.
