Dating Fossils – How Are Fossils Dated?
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. Members of . Dr. Libby, the discoverer of Radiocarbon dating and Nobel Prize winner, showed that purified collagen could not give erroneous ages. The most important are Relative Dating, in which fossils and layers of rock are placed in order from older to younger, and Radiometric Dating, which allows the actual of rock, such as hardened lava and tuff (formed from compacted volcanic ash), could be analyzed chemically to determine the ages, in years, of those rocks. 4) To demonstrate how the rate of radioactive decay and the buildup of the resulting decay product is used in radiometric dating of rocks. 5) To use radiometric dating and the principles of determining relative age to show how ages of rocks and fossils can be narrowed even if they cannot be dated radiometrically.

Can radiocarbon dating be used to determine the age of dinosaur fossils? Are you sure you want to delete this answer?
It has a relatively short half life of years. Radiometric dating is based on the radioactive decay of certain elements.
Their are many other isotopes other than carbon14 that can be used to date dinosaur fossils and much farther back: Potassium has a half-life of 1.
How Does Radiocarbon Dating Work? - Instant Egghead #28
One of its great advantages click here that any sample provides two clocks, one based on uranium's decay to lead with a half-life of about million years, and one based on uranium's decay to lead with a half-life of about 4. Radiometric dating is a very reliable tool for very precise and accurate dating however it is a hard method to perform of fossils and rocks from thousands to billions of years in age.
Many try to discount radiometric dating based solely on the half life of carbon 14 and therefore it cannot be used for things that are billions or millions of years old. That is just not true.
Radiocarbon dating cannot be used to date fossils. Radiocarbon dating works based on the proportions of Carbon isotopes Carbon 14 in organic material and where that carbon comes from the atmosphere i. So land-dwelling plant remains give the most accurate results, remains of land dwelling animals that eat these plants are the next most accurate.
Anything living at the bottom of the ocean or that eats things from the ocean floor gives much less accurate results because they get their carbon from the local environment and it can be a very long time since that was ultimately carbon dioxide dissolving in from the atmosphere. Fossilisation is the replacement of organic compounds with inorganic minerals. So a dinosaur fossil has none of its original organic carbon left.
How do scientists determine the age of dinosaur bones?
Any carbon present would be from sources such a groundwater or from the radioactive decay taking place in the rocks the fossil is found in. Other dating techniques that rely on the properties and isotopes of rocks are used to date fossils. Radiometric relationship shows 2 issues very properly.
It shows the quantity of the daughter isotope and the fee of deterioration. The relationship make 3 assumptions that are actually not observable. It assumes that the decay fee has been consistent, that there exchange into no an infection, and the beginning ratio of determine to daughter isotope.
None of those assumptions are verifiable.
These isotopes have longer half-lives and so are found in greater abundance in older fossils. Schweitzer answered the challenge by testing with antibodies. Bioapatite is a major component of the mineralised part of bones. Schweitzer herself wonders why these materials are preserved when all the models say they should be degraded.
So, that's the reason i do no longer purchase into the uniformitarian worldview. It would not make experience. Why no longer in elementary terms positioned this count to relax. Related Questions Why do creationists often say that radiocarbon dating is inaccurate?

How do scientists determine the age of dinosaur bones? By using radiometric dating to determine the age of igneous bracketsresearchers can accurately determine the age of the sedimentary layers between them. This figure is very similar to the Saurolophus osborni as drawn in the Japanese dinosaur book.
