Over 300 million years old fossilised footprint found

In the past, similar tracks have been discovered by scientists and researchers on various types of terrain on Earth.

More than 300 million-year-old fossilised footprints are discovered at the famous Grand Canyon National Park, USA. These footprints may have clues to what life on Earth was like millions of years ago.

Researchers at the University of Nevada, Las Vegas, have come out with a complete report about fossil footprints found near a hiking trail in the park. As per research papers, these footprints could be 313 million years old and, presumably, are among the oldest animal tracks left. Scientists are still discussing the fact of whether or not these were egg-laying animals.

It’s an important discovery that would suggest the earliest examples of animals walking on sand dunes and could tell scientists the time in history when animals could lay eggs outside of water.

Mark Nebel, paleontology program manager at the Grand Canyon in a statement said, “Some of the conclusions likely are going to be controversial. There’s a lot of disagreement in the scientific community about interpreting tracks, interpreting the age of rocks, especially interpreting what kind of animal made these tracks.”

The claw marks left in the rock are quite distinct and are most common among reptiles today and that’s one of the major reasons why researchers are estimating that these footprints belong to some egg-laying animals.
