The oldest known traces found in the Grand Canyon
Scientists have found the oldest traces of ninetwenty in the world. On the stone path unusual angular steps imprinted in history. The researchers argue that they are at least 310 million years. Discovery found in the Grand Canyon.
About this amazing discovery, scientists reported in October 2018, at the annual meeting of the Society of vertebrate paleontologists in Albuquerque, new Mexico.
The prints are remarkable not only for its antiquity but also some weirdness. Each of them is at an angle of 40 degrees from the direction of the walk, as if the animal was a diagonal gait.
Scientists say that even if the alleged lizard did these steps one by one, they are more like a dance and it’s weird. However, it is possible that the strange angle of the traces is due to the fact that the animal fought with a sand storm, hurricane or just a strong wind that was constantly drifting to the side.
Rowland found out about the tracks by chance in 2016, when his friend, the paleontologist visited the Grand Canyon with students. When they went on the road Bright angel, the group saw a boulder that had fallen from the rocks and broke up.
Milled boulder split the inseam, and there were 28 prints. Friend let Rolando and officials of the Park, and field team pulled the stone aside. In may 2017 Rowland called for the prints, and in March 2018, he returned with a geologist at the University of San Diego Mario Caputo to examine them.
Insights couples are still preliminary; they hope to soon submit a formal scientific paper. Meanwhile, some questions remain at issue, including the kind of animal who raised them.
