They can also date the actual fossils found around the footprints.

Is there a minimum span of time for the fossilization to occur?...it was only 50,000 years....out in the open, subject to weathering.

I am not an archaeologist, but from what I know the footprint must be covered with something before being weathered for fossilization to occur. The dating methods often involve dating the soil deposits over the footprint.
