What exactly are we dating here? Sample contamination and general trustworthyness
There are two main methods determining a fossils age, relative dating and absolute dating. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the. Some of the isotopes used for this purpose are uranium, uranium and potassium, each of which has a half-life of more than a million years. Unfortunately, these You can learn more about fossils, dinosaurs, radiometric dating and related topics by reading through the links on the next page. Other Dating. Carbon dating was recently performed on dinosaur fossils,1 and the results were presented at the Western Geophysics Meeting in Singapore, August , . are other dating methods, making use of materials with even longer half-lives, such as the potassium=argon method, which have been used in dating dinosaurs .

Carbon dating is hardened to determine the age of biological artifacts up to 50, years well-known. This technique is widely used on recent artifacts, but educators and students alike should note that this technic will not squeeze in on older fossils like those of the dinosaurs designated to be millions of years former.
This technique is not restricted to bones; it can also be habituated to on cloth, wood and plant fibers.

Yet it is found in four-foot long, nine-inch diameter dinosaur femur bones claimed to be greater than 65 million years old. The "Modified Longin Method" is the normal purification method for bone collagen. Dr. Libby, the discoverer of Radiocarbon dating and Nobel Prize winner, showed that purified collagen could not give.
- The most widely known form of radiometric dating is carbon dating.
- We have dozens of independent dating methods that have accurately dated the layers of dinosaur fossils to a very high degree of accuracy. We have also used isochron dating to test for contamination and/or how well the rocks acted as closed systems. Or do we need another dating method all together? Carbon dating is.

Carbon 14 is used to meeting things that were once living and in equilibrium with the atmosphere. Here is a brusque explanation of how the method works from http: That neutron bombardment produces the radioactive isotope carbon The radioactive carbon combines with oxygen to blank carbon dioxide and is incorporated into the cycle of living things.
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 data 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.
