These footprints have always been clearly there. Many people passed by without noticing them, until there was a Norwegian geology professor named Arun Kerry Allan Krill, with some students roaming past, saw”fossil footprints that can be recognized at a glance” on the boulder.

The researchers said that these footprints show that there are two different animals passing on the slope of the dune, because”the arrangement of the footprints is clearly shown.” .

Many people visit the park

The Grand Canyon Management Department said:“Researchers reconstructed the sequence of animal footprints, showing a very obvious footwork called a lateral-sequence walk, that is, the two legs on one side of the animal. Move one by one, the hind legs follow the front legs and alternate with the two legs on the opposite side.”

Roland said that there was no information on this in the past. The park also said that this fossil also shows the earliest activity of vertebrates on the dunes.
