The timeline of a Hellenistic Kyrenia shipwreck stumped researchers for decades. But thanks to a cache of ancient almonds, a new study may have a better estimate.After the Kyrenia ship's discovery off the north coast of Cyprus in 1965, a team led by the late marine archaeologist Michael Katzev excavated the wreck in the late ’60s. A lone diverfirst laid eyes on the ancient Kyrenia shipwreck off the north coast of Cyprus nearly 60 years ago.
“We got dates that are very close to those that archaeologists have been recently suggesting but just ever so slightly more recent,” said lead author Sturt Manning, distinguished professor of arts and sciences in classical archaeology at Cornell University in New York. “You only need to have literally a fraction of a percent of this stuff on there, and the date will be wrong, often by hundreds, if not thousands of years,” said Manning, who had tried to date the Kyrenia ship 10 years ago but failed because of PEG.
After investigating, he and his team determined that the Northern Hemisphere international radiocarbon calibration curve, the conversion of measurements to dates based on known tree rings, was outdated for the period between about 400 BC and 250 BC. The authors of a new study dated almonds found aboard the Kyrenia ship to find a new estimated range of years for when the ancient vessel's last voyage took place.
