The cliffs of the Grand Canyon collapsed, revealing a string of the oldest footprints, about 313 million years old
The collapsed cliffs of the Grand Canyon revealed one of the oldest trails, about 313 million years old.
Earliest animal footprints were revealed in Grand Canyon
In the Grand Canyon of the United States, a professor of geology made an amazing discovery while roaming. It is some of the most Ancient footprint.
Relevant parties released news on August 20 that after a cliff collapsed in the Grand Canyon National Park, a huge boulder with footprints of fossils was exposed. Experts say that these fossilized footprints have a history of about 313 million years.
Stephen Rowland, professor of paleontologist at University of Nevada in Las Vegas, The press conference said:”The Grand Canyon is a famous hometown of footprint fossils, and these found now have the longest history. More importantly, these oldest footprints are oviparous animals on the earth, such as reptiles. , Became the earliest evidence of vertebrate walking in the sand dunes.”
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.” .
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.
