The narrator ponders the perplexing problem that ancient people about 4, years ago must have seen dinosaurs because they could not have known what they looked like by merely seeing their skeletons in the ground.

Visual Layers Summer ice has more bubbles and larger crystal sizes Observed to 60, years ago Dust Layers Measured by laser light scattering; most dust is deposited during spring and summer Observed toyears ago Layering of Elec-trical Conductivity Nitric acid from the stratosphere is deposited in the springtime, and causes a yearly layer in electrical conductivity measurement Observed through 60, years ago Contaminant Chemistry Layers Soot from summer forest fires, chemistry of dust, occasional volcanic ash Observed through 2, years; some older eruptions noted Hydrogen and Oxygen Isotope Layering Indicates temperature of precipitation.

Armitage was fired on February 27, This is exactly like it. They asserted that the ceramics gave off regenerated light signals and could be no more than 30 years old. The point is that fluctuations in the rate of C production mean that at times the production rate will exceed the decay rate, while at other times the decay rate will be the larger.

Radiocarbon dating just helps us zero in on a more precise estimate. Among its most cogent critics are experienced masters of the art of prebiotic synthesis, who are well aware of the shortcomings of many of the proposed routes and of the wide gap between the range of molecules that living things employ and those that can be made in the laboratory.
