Romanian cave holds oldest human footprints

Human footprints found in Romania’s Ciur-Izbuc Cave represent the oldest such impressions in Europe, and perhaps the world, researchers say.

About 400 footprints were first discovered in the cave in 1965. Scientists initially attributed the impressions to a man, woman and child who lived 10,000 to 15,000 years ago. But radiocarbon measurements of two cave bear bones excavated just below the footprints now indicate that Homo sapiens made these tracks around 36,500 years ago, say anthropologist David Webb of Kutztown University in Pennsylvania and his colleagues.

Analyses of 51 footprints that remain — cave explorers and tourists have destroyed the rest — indicate that six or seven individuals, including at least one child, entered the cave after a flood had coated its floor with sandy mud, the researchers report in the American Journal of Physical Anthropology.

Published ages for other H. sapiens footprints in Europe and elsewhere go back no more than 33,000 years. At a 2011 conference, scientists said that H. sapiens tracks at Tanzania’s Engare Sero site were 120,000 years old. Those findings have not been published yet, suggesting to Webb a problem with dating or footprint authenticity. Nearly 1-million-year-old footprints of modern human ancestors were recently documented at a British site.
