Carbon dating elephant

von Fange, "Time Upside Down," in Creation Research Society Quarterly, June 1974, p. "Although it was hailed as the answer to the prehistorian's prayer when it was first announced, there has been increasing disillusion with the [radiocarbon] method because of the chronological uncertainties—in some cases absurdities—that would follow a strict adherence to published C-14 dates . What bids to become a classic example of `C-14 irresponsibility' is the 6,000 year spread of 11 determinations for Jarmo, a prehistoric village in northeastern Iraq which, on the basis of all archeological evidence, was not occupied for more than 500 consecutive years."—*C. Reed, "Animal Domestication in the Prehistoric Near East," in Science, 130 (1959), p. "A survey of the 15,000 radiocarbon dates published through the year 1969 in the publication, Radiocarbon, revealed the following significant facts: "[a] Of the dates of 9,671 specimens of trees, animals, and man, only 1,146 or about 12 percent have radiocarbon ages greater than 12,530 years.

By contrast, this revised approach has the effect of `compressing' radiocarbon time,' and speeding up the rate of man's cultural development."—Erich A.

In fact, only one of the samples tested was found to be more than six years of age, based the results of Carbon-14 measurements conducted by Cerling and his fellow researchers.

U-M paleontologist Daniel Fisher worked with Cerling and a former University of Utah researcher, Kevin Uno, on the project.A report about the new method was published online July 1 in Proceedings of the National Academy of Sciences.Fisher studies mammoths and mastodons, and over several decades has developed techniques to interpret the life histories of those prehistoric pachyderms by analyzing growth layers within their tusks."So we can date a tusk now and say, well, this has been traded illegally because of the age of the ivory or the date at which the elephant died."The method analyzes how much radiocarbon, a weakly radioactive byproduct of nuclear weapons testing, is in a tusk.That is then compared with known amounts in the atmosphere over time, allowing scientists to figure out when the tusk was collected.
