Tiny stone artifacts discovered in Uzbekistan may be the oldest known arrowheads, a new study suggests.
It remains unclear whether these stone tools were created by modern humans, Neanderthals or some other group.
Archaeologists found the tools at the site of Obi-Rakhmat in northeastern Uzbekistan. Previous excavations uncovered a variety of stone tools at the site, such as thin and wide blades, and smaller “bladelets.” But numerous small, triangular points — called “microliths” — were overlooked in prior work because they were broken.
Now, in a study published Aug. 11 in the journal PLOS One, the researchers argue that these “micropoints” are too narrow to have fit onto anything other than arrow-like shafts. The stones also display the kind of damage that would be expected from used arrowheads, study co-author Hugues Plisson, an associate scientist at the University of Bordeaux in France, told Live Science.
These micropoints, which are about 80,000 years old, may therefore be the oldest arrowheads in the world — around 6,000 years older than 74,000-year-old artifacts unearthed in Ethiopia, the researchers say.
The scientists expect their work to raise doubts.
“The bows themselves and the arrow shafts have not been preserved, so some skepticism from colleagues is expected,” study co-author Andrey Krivoshapkin, director of the Siberian branch of the Russian Academy of Sciences’ Institute of Archaeology and Ethnography, told Live Science.
