LAS VEGAS, a professor of geology at the University of Nevada, Las Vegas, said he recently identified fossilized reptile songs on a popular trail at the Grand Canyon National Park, the newspaper said.
Professor Steve Rowland theorized that the songs belong to a primitive reptilian baby sized alligator and is about 315 million years old, Las Vegas newspaper reported Thursday.
The 28 fingerprints move diagonally along a stone on the edge of the Grand Angel's trail at the Grand Canyon.
Rowland shared his findings at the annual meeting of the Society of Greek Paleontologists last month in Albuquerque, New Mexico. He hopes to submit a scientific paper in January.
He first saw prints last year during a family vacation and said that "it was quite unusual." He said he had heard of them from another geologist who noticed them during a trip in 2016.
Scientists will probably never know exactly what kind of animal has left the slopes, said Roggende, adding that it provides a lizard-like creature like the iguana Galapagos, similar to a lizard about 2 feet (0.6 meters).
He said he had spoken with representatives of the park about what to do with the stone with the prints and would like to see that he was moved from the canyon and added to a museum.
"More than likely, this will not happen," said Park Speaker Carrie Cobb.
She said that the removal of the scale and its display elsewhere does not correspond to the mission of the National Service for Conservation of Natural Resources.
"But we can put an interpretative sign to tell people what they're looking at," said Cobb.
