"Muscle tissue from beneath the scalp of a mummified musk ox found in frozen muck at Fairbanks Creek, Alaska, has a radiocarbon age of 24,000, while the radiocarbon age of hair from a hind limb of the carcass is 17,200.
A life span exceeding 7,000 years for a specimen of this species is doubtful.
Brown, "Radiocarbon Age Measurements Re-examined," in Review and Herald, October 28, 1971, pp. Radiocarbon in the atmosphere was markedly different prior to 1600 B. "It was found that the activity of radiocarbon in the atmosphere was going up and down even before the Industrial Revolution [when additional smoke began polluting the air]."—*H. For a 40,000 year old sample, the figure is only 5 percent, while an error of 50,000 years can be produced by about 1 percent of modern material. The age of prehistoric artifacts, the age of the earth, and that of the universe would be thrown into doubt."—*F. Jueneman, article in Industrial Research, 14 (1972), p. "Some geologists question the use of the C-14 method for samples stored under moist conditions. von Fange, "Time Upside Down," in Creation Research Society Quarterly, June 1974, p.
An asterisk ( * ) by a name indicates that person is not known to be a creationist. "Well authenticated dates are known only back as far as about 1600 B. "There are two basic assumptions in the radiocarbon method.Marine records, such as corals, have been used to push farther back in time, but these are less robust because levels of carbon-14 in the atmosphere and the ocean are not identical and tend shift with changes in ocean circulation.Bronk Ramsey’s team aimed to fill this gap by using sediment from bed of Lake Suigetsu, west of Tokyo."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! Ogden III, "The Use and Abuse of Radiocarbon," in Annals of the New York Academy of Science, Vol. If it does not entirely contradict them, we put it in a footnote. We learned rather abruptly that these numbers, these ancient ages, are not known; in fact, it is about the time of the first dynasty in Egypt that the last [earliest] historical date of any real certainty has been established."—*W. Libby, "Radiocarbon Dating," in American Scientist, January 1956, p. [Libby was the one who pioneered the discovery of Carbon ! "It may come as a shock to some, but fewer than 50 percent of the radiocarbon dates from geological and archaeological samples in northeastern North America have been adopted as `acceptable' by investigators."—*J. In the Proceedings of the Symposium on Radiocarbon Variations and Absolute Chronology held at Uppsala in 1969, T. A famous American colleague, Professor Brew, briefly summarized a common attitude among archaeologists towards it, as follows: If a C-14 date supports our theories, we put it in the main text.The technique hinges on carbon-14, a radioactive isotope of the element that, unlike other more stable forms of carbon, decays away at a steady rate.Organisms capture a certain amount of carbon-14 from the atmosphere when they are alive.By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon-14 decay can be worked out, thereby giving an age for the specimen in question.But that assumes that the amount of carbon-14 in the atmosphere was constant — any variation would speed up or slow down the clock.Various geologic, atmospheric and solar processes can influence atmospheric carbon-14 levels.Since the 1960s, scientists have started accounting for the variations by calibrating the clock against the known ages of tree rings.Wood fragments from the gravel in which the remains were buried have a radiocarbon age of approximately 5,000 years.
