Fossilized footprints of several animals are also present, but the fact that they intersect the human footprints shows they were not traveling with the people. In 1874, construction workers discovered the footprints. The United States medical doctor and archaeological collector, Earl Flint, brought the footprints to the attention of the international science community and media in 1884. The Carnegie Institution of Washington began the first scientific analysis and excavations of the area in 1941 and 1942.
