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.

It's not just ordinary sleep, it's a biological/natural wonder and a bear's miracle.

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.

Brian Hedlund and Ariel Friel collect microbes living for tens of thousands of years in the subsurface of the earth. By studying these microorganisms, they hope to gain clues about potential life on Mars and other planets.

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.

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

What could be the oldest footprints ever, of a lizard like-creature that roamed Earth 310 million years ago have been discovered in the Grand Canyon. Made by one of the first reptiles that ever lived the prints make it look as if the creature was line dancing.

Considering how many people willingly wait in long lines, it’s surprising how much they hate it.

The Kepler telescope has run out of fuel and officially entered retirement. Luckily, there is a replacement on the way to continue our observation of the stars.

Astronomers expect TESS to find thousands more planetary systems.

We’ve entered some profoundly unfamiliar planetary territory.
