LAS VEGAS (AP) – A geology professor from the University of Nevada, Las Vegas, said he recently identified fossil traces from a reptile along a popular trail in the Grand Canyon National Park, reported a newspaper.
Professor Steve Rowland, theorized that the tracks belong to a primitive reptile, the size of a baby alligator and return to about 315 million years, the Las Vegas Review Journal reported on Thursday.
The 28 footsteps run diagonally across a rock on the edge of the Grand Canyon Bright Angel Trail.
Rowland shared their findings at the Society of Vertebrate Paleontology Annual Meeting last month in Albuquerque, New Mexico. He hopes to submit a scientific document in January.
He saw the first time last year during a family holiday and said that they “turned out to be quite extraordinary”. He said he heard of them from another geologist who discovered them during a 201
Scientists will probably never know exactly what kind of animals left the trails, said Rowland and added that he represents a lizard-like creature about 2 feet 0.6 meters) similar to a Galapagos iguana.
He said he was talking to the park’s officials about what to do with the boulder with the prints and would like to see it moved from the canyon and added to a museum.  “More likely it will not happen,” says spokesman Kari Cobb.
She said to remove the mountain and show it elsewhere not in line with the National Park Service mission to conserve resources in its natural state.  “But we can put an interpreting sign that tells people what they’re looking at,” said Cobb.
