Controversy over carbon dating
We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].
That included protecting the samples, avoiding cracked areas in the bones, and meticulous pre-cleaning of the samples with chemicals to remove possible contaminants.
(2010) demonstrated that radiocarbon analyses could indeed give accurate and precise dates for Egypt and Egyptian history in the second millennium BC. Revised estimates for the volume of the Late Bronze Age Minoan eruption, Santorini, Greece.
Thus, if radiocarbon worked in mid second millennium BC Egypt, then it should work also in the Aegean. Journal of the Geological Society, London, 171: 583-590.
Researchers have found a reason for the puzzling survival of soft tissue and collagen in dinosaur bones - the bones are younger than anyone ever guessed.
Carbon-14 (C-14) dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22,000 to 39,000 years old.
