Indeed, all of the reference books confidently label charts with firm dates for the appearance of fishes, the demise of the dinosaurs, and so on. Alas, things are not quite as certain as they appear. Radiometric dating is not all that precise; errors may be large indeed. Take the Pennsylvanian period for example. It is part of the Carboniferous period, when many of the great coal deposits were laid down. The classical duration of the Pennsylvanian - ... used in many texts -- is 34 million years. A meticulous new study of central European stratigraphy now pegs the Pennsylvanian as spanning only 19 million years. Now that's a 44% change! This new figure for the duration of the Pennsylvanian has already cast doubt on the origin of the famous Pennsylvanian cyclothems (repetitive strata) in North America. It had been thought that these seemingly cyclic deposits were correlated with sea level changes forced by variations in the earth's orbit (the Milankovitch periods). With this substantial compression of Pennsylvan-ian time, this correlation falls apart. The cyclothems, which are of impressive area and thickness, now seem to have been created by some other, still unrecognized phenomenon. (Klein, George deV.; "Pennsylvanian Time Scales and ...

But only 6 inches below the Clovis level, the diggers gingerly brushed the dirt off crude projectile points that were clearly not of Clovis manufacture. This level seems to be about 5,000 years older than the Clovis level according to radiometric dating of charcoal. Skeptics suggest that there has been mixing of the sandy soil and that these early dates are suspect. But thermoluminescent dating has confirmed the 5,000-year time gap. Thorough analyses of the soil with its plant and animal re-mains indicated little if any mixing. D.

Science Frontiers ONLINE No. 129: MAY-JUN 2000 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects The Anomalous Antiquity of Some Landforms All over the planet, but particularly in Australia, there exist great expanses of land surface that fossils and radiometric dating tell us are tens of millions of years old. This doesn't seem very serious until we learn that, given today's erosion rates, these landforms should be deeply eroded or, more likely, completely erased by the forces of nature. This paradox has long been used by Creationists to challenge geological dating methods. Mainstream geologists do recognize the paradox but have had scant success in resolving it. For example, geologist C.H . Crickmay wrote: Again, one finds all ... the world, even high above and far distant from existing waterways, smooth-surfaced and level ground -- including everything from small terraces to broad, flat plains -- much of it still bearing intact a carpet of stream alluvium. Such lands were carved and carpeted, evidently, by running water, even though they are now in places where no stream could possibly run... What is remarkable about them is the perfection with which they have out-lasted the attack of "denudation" for all the time that has passed since they lay at stream level. (The Work of the River, New York, 1974) This paradox of uneroded ancient landforms remains as obdurate as the landforms themselves.

Feb 1990 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Australasian tektites coughed up by a moon of jupiter?The Australasian tektites are glassy blobs found on or near the surface of the ground from the Philippines, through southeast Asia, all the way to Tasmania. Similar but much smaller "microtektites" appear in deapsea de posits in the adjacent oceans. Radiometric and fission-track dating indicate that the tektites solidified about 700,000 years ago. Yet, their geological age, as measured by the age of the terrestrial sediments in which they are found, is only a few thousand years. This great disparity in age engendered a confrontation between geologists and geophysicists. The latter insisted on their 700,000-year figure; the former said " ... so" but the tektites are still found only in very young, superficial sediments. The point here is that time-of-solidification may not be the same as time-of-fall. At stake is the prevailing theory, now dogmatically proclaimed, that tektites are created when a large asteroid impacts the earth, ejecting molten droplets of rock which shower back to earth as solidified tektites. No one has ever found a suitably large crater ( 200 miles in diameter) assignable to the Australasian tektite strewn field. Nevertheless, the impact model prevails; and the young geological age of the tektites is dismissed as erroneous. A Soviet scientist, E.P . Izokh, has recently proposed a radically different scenario that would produce both the young and old dates. If a moon, or ...

In 1991, construction workers at Tysfjord, Norway, 125 miles north of the Arctic Circle, accidentally dug up polarbear bones that were later radiometrically dated as at least 42,000 years old, probably 60,000. R. Lie, a zoologist at the University of Bergen, and other scientists subsequently found the bones of two more polar bears in the area. These were dated as about 20,000 years old. An associated wolf's jaw was pegged at 32,000 years. The problem is that Norway and ... other northern circumpolar lands are believed to have been buried under a thick ice cap during the Ice Ages.
