"It's the oldest trackway always discovered inwards the Grand Canyon inwards an interval of rocks that nobody idea would bring trackways inwards it, as well as they're with the earliest reptile tracks on earth," said Rowland.
Rowland said he's non prepared to state that they're the oldest tracks of their sort always discovered, simply it's a possibility, every bit he's nonetheless researching the discovery.
"In damage of reptile tracks, this is actually old," he said, adding that the tracks were created every bit the supercontinent Pangaea was starting fourth dimension to form.
Rowland was firstly alerted to the tracks inwards jump 2016 past times a colleague who was hiking the trail with a grouping of students. The boulder ended upwardly along the trail after the collapse of a cliff.

"My firstly impression was that it looked real bizarre because of the sideways motion," Rowland said. "It appeared that ii animals were walking side-by-side. But you lot wouldn't facial expression ii lizard-like animals to live on walking side-by-side. It didn't brand whatsoever sense."
When he arrived home, he made detailed drawings, as well as began hypothesizing nearly the "peculiar, line-dancing gait" left behind past times the creature.
"One argue I've proposed is that the animate beingness was walking inwards a real potent wind, as well as the air current was blowing it sideways," he said.
Another possibility is that the gradient was likewise steep, as well as the animate beingness sidestepped every bit it climbed the sand dune. Or, Rowland said, the animate beingness was fighting with or as well as therefore other creature, or engaged inwards a mating ritual.
"I don't know if we'll live on able to rigorously pick out betwixt those possibilities," he said.
He plans to issue his findings along with geologist Mario Caputo of San Diego State University inwards January. Rowland also hopes that the boulder is presently placed inwards the geology museum at the Grand Canyon National Park for both scientific as well as interpretive purposes.
Meanwhile, Rowland said that the footprints could belong to a reptile species that has never yet been discovered.
"It absolutely could live on that whoever was the trackmaker, his or her bones bring never been recorded," Rowland said.
