The Lamont-Doherty scientists conducted their analyses on samples of coral drilled from a reef off the island of Barbados.

One such indicator is the uranium-thorium dating method used by the Lamont-Doherty group.Scientists at the Lamont-Doherty Geological Laboratory of Columbia University at Palisades, N.Y., reported today in the British journal Nature that some estimates of age based on carbon analyses were wrong by as much as 3,500 years.The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.Libby of the University of Chicago in immediate post-WW2 years.
