��ҳ| �鶹��ýӳ�� 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.

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.
