Summary:
Scientists have
discovered the oldest recorded stone tool ever to be found in Turkey, revealing
that humans passed through the gateway from Asia to Europe much earlier than
previously thought, approximately 1.2 million years ago. The chance find of a
humanly-worked quartzite flake, in ancient deposits of the river Gediz, in
western Turkey, provides a major new insight into when and how early humans
dispersed out of Africa and Asia

Scientists have
discovered the oldest recorded stone tool ever to be found in Turkey, revealing
that humans passed through the gateway from Asia to Europe much earlier than
previously thought, approximately 1.2 million years ago.
According to research published in the journalQuaternary Science Reviews,
the chance find of a humanly-worked quartzite flake, in ancient deposits of the
river Gediz, in western Turkey, provides a major new insight into when and how
early humans dispersed out of Africa and Asia.
Researchers from Royal Holloway, University of London, together with an
international team from the UK, Turkey and the Netherlands, used high-precision
equipment to date the deposits of the ancient river meander, giving the first
accurate timeframe for when humans occupied the area.
Professor Danielle Schreve, from the Department of Geography at Royal
Holloway, said: "This discovery is critical for establishing the timing
and route of early human dispersal into Europe. Our research suggests that the
flake is the earliest securely-dated artefact from Turkey ever recorded and was
dropped on the floodplain by an early hominin well over a million years
ago."
The researchers used high-precision radioisotopic dating and palaeomagnetic
measurements from lava flows, which both pre-date and post-date the meander, to
establish that early humans were present in the area between approximately 1.24
million and 1.17 million years ago. Previously, the oldest hominin fossils in
western Turkey were recovered in 2007 at Koçabas, but the dating of these and
other stone tool finds were uncertain.
"The flake was an incredibly exciting find," Professor Schreve
said. "I had been studying the sediments in the meander bend and my eye
was drawn to a pinkish stone on the surface. When I turned it over for a better
look, the features of a humanly-struck artefact were immediately apparent.
"By working together with geologists and dating specialists, we have
been able to put a secure chronology to this find and shed new light on the
behaviour of our most distant ancestors."
