Identifying The Age
Incorporating findings from prior studies of the Manakacha Formation with maps of the region’s geology, the researchers were able to determine the approximate age of the tracks with surprising accuracy. And it turned out that Krill had been correct to pull over to the side of the route and take a closer look at the seemingly benign pebble that he had discovered.

As a result, they broke all kinds of records. According to reports, they’re believed to be the earliest fossilized vertebrate footprints ever discovered in the Grand Canyon, dating back millions of years.
