A Nevada geology professor says he recently identified fossilized tracks from a reptile along a popular trail in Grand Canyon National Park.

It’s time for a dinosaur update. A few years ago, UNLV researchers were tasked with trying to figure out what kind of prehistoric animal made tracks that were fossilized in the area of Gold Butte National Monument.

A geology professor with the University of Nevada, Las Vegas discovered a set of footprints that were left behind by a reptile-like creature 310 million years ago at the Grand Canyon.

Eons ago, somewhere on Earth, a prehistoric lizard-like creature crept across a wet sandy dune next to a shallow continental sea.

About 315 million years ago — long before dinosaurs roamed the Earth — an early reptile scuttled along in a strangely sideways jaunt, leaving its tiny footprints embedded in the landscape, new research finds.

Footprints of a “lizard like-creature” 310 million years old have been unearthed in the Grand Canyon, making them potentially the oldest reptile footprints ever found.

Geologists have uncovered a set of 28 footprints along a hiking trail in Grand Canyon National Park. The footprints were left by a reptile-like creature and are cemented in a 310 million-year-old rock, making them oldest tracks ever to be found in the site.
