Nothing earth-shaking or groundbreaking, but still interesting.
I have to ask, “What kept these footprints, and others just like them in various places, preserved for multiple millennia?”
What place or era has no rain, wind, snow, drifting sands or other animals to obliterate the footprints within a few days or at least weeks?
If you leave footprints along a muddy stream or lake practically anywhere on Earth, they will be gone fairly quickly.
Something happened to stagnate the climate and produce no weather phenomena to do the erasures that would normally occur.
