A geologist has discovered a pair of fossil footprints that researchers say are the oldest of their kind in the Grand Canyon, dating back 313 million years.

Researchers said the fossils show two animals passing at different times along the slope of a sand dune.

The findings were published on Wednesday in the journal PLOS One.
