"In 1975 Dr Stanley Rhine of the University of New Mexico announced the discovery of footprints human in appearance in strata estimated to be 40 million years old. Similar discoveries were made in Kenton, Oklahoma and in Wisconsin.
Steiger, author of Worlds Before Our Own, relates yet another instance, an engineer called Johnson found footprints in an ancient sandstone near Tulsa. Johnson had had to remove earth and roots to uncover the fossils which evidently were human-like, and which were impressed in a block of sandstone weighing about 15 tons.
The largest and clearest tracks yet discovered were found in 1973. The footprints were described as 21 inches long, eight inches wide. and five inches across the instep. The creature's stride was seven feet. The impressions are in the same layer of rock as tracks of the anatosaur, a duck-billed dinosaur. Steiger comments:
If the tracks are accepted as human, then scientists will be forced either to place man back in time to the Cretaceous period or to bring the dinosaurs forward to the Pleistocene period."
