Radiometric dating is used to tell the age of rocks

Mckee, "The chief significance of ripple lamination in the geologic record is that it is an indicator of environments involving large and rapid sand accumulation...areas where addition of new sand normally is at a slow rate, have little chance of developing into superimposed ripple lamination... of Geology, Harvard, "it is reasonable to postulate a very rapid rate of deposition; that is a single lamina would probably be deposited in a period of seconds or minutes rather than in a period of hours. Frankfurt, "This proves instantaneous deposition of the individual beds, as postulated by the turbidity-current theory. For more than 65 million years the remains of the vegetarian duck-billed dinosaurs and other creatures lay buried in the now-frozen tundra, which was once a coastal swamp with a subtropical-to-temperate climate.'...their structure was porous and the fossils were not remineralized.' Therefore, in their deep freeze, the Alaskan bones may well have preserved some of their DNA." Omni, 1/90, p.32 DINOSAUR blood cells, SOFT TISSUE "Round and tiny and nucleated, they were threaded through the bone like red blood cells in blood vessels. It was exactly like looking at a slice of modern bone. Hill Dean of College of Mines & Mineral Industries, "A rather startling and serendipitous discovery resulted....

In contrast, areas in which sand accumulates periodically but rapidly, as in river flood plains were sand laden waters of strong floods suddenly lose velocity are very favorable for building up ripple-laminated deposits." Society of Economic Paleontologists and Mineralogists, p.107. ...there is factual evidence from both field observation and experiment that laminae composed of bed material are commonly deposited by current action within a period of seconds or minutes." V.36, No. ..not accumulate gradually but were cast instantaneously by turbidity currents each bed in its entire thickness, in a matter of hours or less." Journal of Geology, V.70, p. But blood cells in a dinosaur bone should have disappeared eons ago. These observations suggest that in their formation, high rank coals,...probably subjected to high temperature at some stage in their history.

In other formations where articulated skeletons of large animals are preserved, the sediment must have covered them within a few days at the most.

Abundant fossil shells likewise indicate rapid burial, for if shells are long exposed on the sea floor they suffer abrasion or corrosion and are overgrown by sessile organisms or perforated by boring animals.

At the rate of deposition postulated by Schuchert, 1000 years, more or less, would have been required to bury a shell 5 inches in diameter.

With very local exceptions fossil shells show no evidence of such long exposure." Principles Of Stratigraphy, p.128. T., "Because they are one of the commonest and most widespread of original sedimentary features, they have been described and illustrated in countless reports. Ripple marks are preserved in conglomerates, sandstones, and siltstones, and in clastic limestones and dolostones. Many examples have been described from rocks of all ages..." Sequence In Layered Rock, p.93, 95. '" Science, Research News, V.261, 9/7/'93 "I had one reviewer tell me that he didn't care what the data said, he knew that what I was finding wasn't possible, says Schweitzer.

A longer excerpt might be desirable but ineffective.

The wonder is, surely, that the remaining half come out to be accepted. Conference (145 International Scientists), Science, Vol. If we combine his results with the latest estimates of time based on radioactive minerals, we get the figures in Table 5, in which the last column indicates the estimated average rate of deposition.

There are gross discrepancies, the chronology is uneven and relative, and the accepted dates are actually selected dates." Anthropological Journal of Canada, Vol. Internal evidence in the strata, however, belies these estimates.

However this web site ( convinced me that they could be useful as a reference tool, especially for those who attend the lectures, and I agreed.

I commented at the time that some of the quotes would not make sense without the lecture.

Despite 35 years of technological refinement and better under-standing, the underlying assumptions have been strongly challenged... "Throughout the conference emphasis was placed on the fact that laboratories do not measure ages, they measure sample activities. To some thoughtful stratigraphers this amazing discovery presented a dilemma, for if the known stratified rocks have been accumulating throughout this vast span of time the average rate of deposition must have been extremely slow, yet there is very good evidence that individual beds accumulated rapidly.
