Radiocarbon dating dinosaur fossils
Today, innovative techniques provide further confirmation and understanding of the history of life.Biologists actually have at their disposal several independent ways of looking at the history of life - not only from the order of fossils in the rocks, but also through phylogenetic trees. Relative dating is done by observing fossils, as described above, and recording which fossil is younger, which is older.The discovery of means for absolute dating in the early 1900s was a huge advance.The methods are all based on radioactive decay: The first radiometric dates, generated about 1920, showed that the Earth was hundreds of millions, or billions, of years old.Since then, geologists have made many tens of thousands of radiometric age determinations, and they have refined the earlier estimates.A key point is that it is no longer necessary simply to accept one chemical determination of a rock’s age.Paleontologists now apply sophisticated mathematical techniques to assess the relative quality of particular fossil successions, as well as the entire fossil record.These demonstrate that, of course, we do not know everything (and clearly never will), but we know enough.
Typical error potential listed for the above C-14 testing is only a few centuries but sometimes even less than one century. The carbon-14 dating research (C-14 or radiocarbon dating) was done over a period of years, with many samples from bones of several types, including: (Montana) Blatant Censor Instead of Correction If some scientist giving a lecture in a science conference makes a mistake, why not correct that mistake?Open discussion, with details, makes for an atmosphere where the truth may come into open view.Carbon-14 dating was recently performed on dinosaur fossils,1 and the results were presented at the Western Geophysics Meeting in Singapore, August 2012, a gathering of approximately two thousand scientists. Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods.
