About me:
The ratio of carbon to carbon at the moment of death is the same as every other living thing, but the carbon decays and is not replaced. The carbon decays with its half-life of 5, years, while the amount of carbon remains constant in the sample. By looking at the ratio of carbon to carbon in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of a formerly living thing fairly precisely. So, if you had a fossil that had 10 percent carbon compared to a living sample, then that fossil would be:. Because the half-life of carbon is 5, years, it is only reliable c-14 dating fossils dating objects up to about 60, years old.

Carbon dating is used to determine the age of biological artifacts up to 50, years c-14 dating fossils. This technique is c-14 dating fossils used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers. Carbon dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things.

TASC typically c-14 dating fossils the 2nd Thursday monthly, at 7: Organic matter in the fossil record generally dates by carbon 14 C14 dating to about 20, to 40, years. Why is this? Why are the dates so different? Many creationists believe that radioactive decay was faster in the past. However, in this talk I want to concentrate on reasons c-14 dating fossils believe the C14 dates are more accurate and that they give evidence that all life on earth is very young. If decay rates were faster in the past, then even the C14 dates could be too old.

Carbondated dinosaur bones are less than 40, years old. 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 C dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22, to 39, years old. Since dinosaurs are thought to be over 65 million years old, the news is stunning - and more than some can tolerate. After the AOGS-AGU conference in Singapore, the abstract was removed from the conference website by two chairmen because they could not accept the findings. Unwilling to challenge the c-14 dating fossils openly, they erased the report from public view without a word to the authors. When the authors inquired, they received this letter: They did not look at the data and they never spoke with the researchers. They did not like the test results, so they censored them. Carbon is considered to be a highly reliable dating technique.
