According to a statement released by Public Library of Science, researchers have applied updated radiocarbon calibration techniques to revise the dating of the wreck of the Kyrenia, an ancient ship that was discovered and excavated off the coast of Cyprus in the late 1960s. Based on coins and ceramics recovered from the wreck, researchers had dated the ship to the late fourth or early third century B.C., which did not align with the radiocarbon dates from decades ago. Tree-ring dating is crucial in obtaining accurate radiocarbon dates because it helps correct errors caused by variations over time in atmospheric carbon....
