The finds of this study have been detailed in the journal Ichnos and can be accessed here. And they must work fast to record and analyse them before these prints, vulnerable to erosion, are destroyed by the ocean and winds. Researchers suspect that more hominin ichnosites lay in wait to be discovered on the Cape South coast.

OSL can be used to date surfaces even if they were quickly buried. This dating technique works by measuring the time that has elapsed since the grains of quartz or feldspar in or near fossilised tracks were last exposed to sunlight. The study was made possible using optically-stimulated luminescence (OSL).

Other South African ichnosites included hominin tracks, a knee impression, and “ammoglyphs” - denoting any pattern made by humans that has been preserved over time.įootprint evidence can provide not just an indication of humans travelling across these surfaces as individuals or groups but also evidence of some of the activities that they engaged in, the authors wrote in the study.

This number highlights that while our ancient ancestors have certainly left their footprints behind, they’re also deceptively hard to find.

More than 100 walking trails preserved in rocks, ash, and mud have been unearthed by paleoanthropologists since, but only 14 of these are over 50,000 years old. And when the nearby volcano erupted again, more layers of ash settled atop their footprints, preserving the oldest-ever hominin (humans and all of our extinct bipedal ancestors) trails found to date.īut it has been a little over 40 years since these footprints were found at the site of Laetoli in Tanzania, Africa. Over 3.6 million years ago, three early humans ( Australopithecus afarensis) walked through wet volcanic ash.
