Human fossil footprints in ancient rock have also been found in OK, KS, UT, AZ, Australia, Africa, Europe, and Russia. One of the biggest known locations of dinosaur tracks is in Turkmenistan. There are estimated to be over 1500 dinosaur tracks there and several investigators claim that at least four separate trails of human footprints have been seen there too. Dr. Patton was trying to get over there to investigate the human footprint claim.
