A Cliff Collapsed In The Grand Canyon And Unearthed This...

In 2016, geologist Alan Krill discovered fossilized footprints on a fallen boulder along the Bright Angel Trail in the Grand Canyon. The boulder, from the Manakacha Formation, revealed 313-million-year-old trackways, marking the oldest vertebrate footprints in the canyon. Collaborating with paleontologist Stephen Rowland, the tracks were identified as belonging to a shelled, egg-laying creature using a lateral sequence gait, adapting to desert-like conditions. This groundbreaking find reshaped our understanding of early terrestrial life during the Carboniferous period. The Grand Canyon remains a vital site for uncovering Earth’s geological and biological history, continuing to inspire awe and scientific exploration
