"A mastodon skeleton, found at Ferguson Farm near Tupperville, Ontario, provided a radiocarbon age of 8,900 for the collagen fraction of bones and a radiocarbon age of 6,200 for high organic-content mud from within the skull cavities. Flint, "Radiocarbon Dating," in Science, February 8, 1957, p. Only if all the factors producing C-14 in living tissue are unchanged, can past radiodating results be reliable "An earlier increase in neutrino levels] must have had the peculiar characteristic of resetting all our atomic clocks.It is unlikely that this skeleton could have survived exposure for 2,700 solar years before emplacement in peat."—Robert H. Waterbolk, "Groningen Radiocarbon Dates III," in Science, December 19, 1958, p. "Local variation, especially in [marine] shells, can be highly significant . The most significant problem is that of biological alteration of materials in the soil. To produce an error of 50 percent in the age of a 10,000 year old specimen would require the replacement of more than 25 percent of the carbon atoms. This would knock our C-14, potassium-argon, and uranium-lead dating measurements into a cocked hat!The first of these problems is the fact that the original ratio of carbon and radioactive carbon is unknown.The second problem is that the possibility of contamination of the sample over time is quite high.

"There are two basic assumptions in the radiocarbon method. 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.Of over 4,000 quotations in the books this Encyclopedia is based on, only 164 statements are by creationists. One is that the carbon 14 concentration in the carbon dioxide cycle is constant.You will have a better understanding of the following statements by scientists if you will also read the web page, . The other is that the cosmic ray flux has been essentially constant—at least on a scale of centuries."—*J. Kulp, "The Carbon 14 Method of Age Determination," in Scientific Monthly, November 1952, p. "Hair from the Chekurovka mammoth that was found in the Lena River delta region of Russia has a radiocarbon age of 26,000 [years] while the radiocarbon age of peat only eighteen inches above the carcass is 5,610.
