Claim CC101:
Human and dinosaur footprints have been found together in Cretaceous rocks of the Paluxy Riverbed near Glen Rose, Texas.Source:
Response:
- The alleged human footprints involve a number of misidentified and spurious phenomena.
- Most supposed "man tracks" in the riverbed are forms of elongate, metatarsal dinosaur tracks-- made by dinosaurs that at times impressed their metatarsi (soles and heels) as they walked. When the digit impressions of such tracks are subdued by mud-collapse, erosion, infilling, or a combination of factors, the remaining metatarsal portions often superficially resemble human footprints. However, when well cleaned such tracks show definite indications of tridactyl, dinosaurian digit patterns (Kuban, 1986a, 1986b; Hastings, 1987).
- Some of the reputed human prints are erosional features or other natural irregularities. They do not show clear human features without selective highlighting, nor occur in natural striding sequences (Cole et al, 1985).
- A smaller number of alleged "giant man tracks" are carvings on loose blocks of rock (Godfrey, 1985; Kuban and Wilkerson, 1989).
- Creationists often failed to exercise scientific rigor and due caution in their early Paluxy field work and promotions. Subseqwuently many also mischaracterized or minimized the mainstream work and alalyses which prompted creationist reevaluations of the evidence (Schadewald, 1986; Kuban, 1986c). However, most no longer use the Paluxy tracks among their arguments, and major creationist organizations such as ICR and AIG have advised that the Paluxy tracks not be cited as evidence against evolution. Continuing "man track" claims by a few individuals such as Carl Baugh and Don Patton have not stood up to close scrutiny (Kuban, 1989).
