{"post":"Ancient footprints offer rare glimpse into lives of extinct human relatives. A remarkable set of footprints preserved along the shores of Kenya’s Lake Turkana from more than one million years ago is giving scientists an unusually detailed look at how one of humanity’s extinct relatives may have lived, moved and socialized.
The newly published study, appearing in the Proceedings of the National Academy of Sciences, analyzed 21 fossilized footprints left behind by eight individuals belonging to Paranthropus boisei, an ancient human relative that lived alongside Homo erectus during the Early Pleistocene.
In an interview with CTVnews.ca on Monday, lead author and associate professor of biology at Chatham University Kevin Hatala said: “They probably weren’t all there at exactly the same time, but they’re definitely all moving through this space, maybe within hours of each other, or at least within a day or two.”
“We think there’s potentially a group of them who are moving through this area together as well, just based on the orientations of their trackways,” he added. “They seem to be moving in the same direction and at similar speeds too.”
Researchers say footprints provide something fossilized bones rarely can: a snapshot of behaviour captured in a single moment.
“The special thing about footprints, scientifically, is that they preserve an instant in time,” Kay Behrensmeyer, senior research geologist and curator of vertebrate paleontology at the Smithsonian’s National Museum of Natural History, said in a press release issued by the museum. “They also allow people to relate to these fossils much more easily than an isolated piece of bone or jaw.”
The tracks were first discovered in northern Kenya in 1978 after Behrensmeyer noticed what turned out to be a fossilized hippo footprint while colleagues were excavating ancient sediment. The site was later reburied to protect it before researchers returned in 2016 and 2023, uncovering many more footprints preserved in the same layer of rock.
Volcanic ash surrounding the site allowed researchers to date the trackway to about 1.43 million years ago."}
