LAS VEGAS — A geology professor from the University of Nevada, Las Vegas, said he recently identified fossilized tracks from a reptile along a popular trail in Grand Canyon National Park, a newspaper reported.
Professor Steve Rowland theorized that the tracks belong to a primitive reptile the size of a baby alligator and date back about 315 million years, the Las Vegas Review-Journal reported Thursday.
