Are you sure you want to delete this answer? Yes Sorry, something has gone wrong. Other answers are a bit inaccurate. If it’s an actual bone, and not a fossilized bone, then carbon dating is the ticket. The guy who told you it is just guesses Carbon dating is based on sound science. The principle behind carbon dating is actually kind of simple. Carbon decays into nitrogen at a known and constant rate of decay.
What happens if you date dinosaur bones using the carbon-14 method?
Jump to navigation Jump to search Fluorine absorption dating is a method used to determine the amount of time an object has been underground. Fluorine absorption dating can be carried out based on the fact that groundwater contains fluoride ions. Items such as bone that are in the soil will absorb fluoride from the groundwater over time.

Though they may know it as carbon dating or carbon 14 dating, there is an understood notion that when anything old is found, like an ancient artifact, it can be radiocarbon dated to find out exactly how old it is. Yet, as simple and straightforward as this seems, the process of dating objects via radiocarbon is far from simple and straightforward. Here I will present what radiocarbon is, the dating methods, the assumptions that govern them, and the known discrepancies that plague the method.
With a thorough understanding of this dating method, it is my opinion that its ingenious fundamentals can be appreciated, yet greatly overshadowed by its limitations. Radiocarbon Every day cosmic rays bombard our atmosphere. These cosmic rays release free neutrons which zip around our nitrogen rich atmosphere at high velocities. As the Carbon 14 slowly descends into our lower atmosphere it bonds with oxygen becoming the very unpopular CO2 greenhouse gas Bowman, Though the vast majority of CO2 is comprised of the more common and stable isotope of carbon, carbon 12 C12 , a small fraction of CO2 one in million , contains C As is common fact, plants photosynthesize and consume CO2, fixing its carbon.
Since a small fraction of CO2 contains C14, some of carbon fixed within the plant is that of C When an organism dies, it obviously no longer eats, photosynthesizes, etc. There is therefore no way for additional C14 to enter the organism once dead. This leads to an important fact: Only materials once part of the biosphere organic can be dated with radiocarbon Bowman, 12 , with the exception of some non-organic materials which can be dated with radiocarbon if their formation involved C
How accurate are Carbon-14 and other radioactive dating methods?
Archaeology — Archaeology, or archeology, is the study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, Archaeology can be considered both a social science and a branch of the humanities. In North America, archaeology is considered a sub-field of anthropology, archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.
Archaeology as a field is distinct from the discipline of palaeontology, Archaeology is particularly important for learning about prehistoric societies, for whom there may be no written records to study. The discipline involves surveying, excavation and eventually analysis of data collected to learn more about the past, in broad scope, archaeology relies on cross-disciplinary research. Archaeology developed out of antiquarianism in Europe during the 19th century, Archaeology has been used by nation-states to create particular visions of the past.

Until recent years, scientists who believe in creation haven’t had the necessary resources to explore radiometric dating in detail. A 10 gram sample of U Now that has changed, and some important discoveries are being made. When granite rock hardens, it freezes radioactive elements in place. The most common radioactive element in granite is Uranium This element is locked in tiny zircons within the granite.
As part of the decay process, helium is produced. While it stays within the zircon for a period of time, being a very small atom, helium escapes the zircon within a few thousand years. When creation scientists studied granite samples, they made interesting discoveries. The samples were from a mile below the earth, which, according to inflated evolutionary years, were 1. The helium still locked in the samples was studied as well as the rate at which the helium diffused from the rock.
How Does Carbon Dating Work
Many such lines of evidence multiplying as at youngearth. On how to date a dinosaur, Real Science Radio’s Bob Enyart interviews Hugh Miller, a member of the international scientific team that presented at the AGU geophysical conference in Singapore, the carbon dating results from five respected laboratories around the world of bones from ten dinosaurs from the Gobi Desert in China, from Europe, Alaska, Texas, and Montana.
Yet each of these dinosaurs had plenty of radiocarbon as expected in that virtually every relevant peer-reviewed paper on the topic confirms the presence of endogenous soft tissue in fossils; see DinosaurSoftTissue.
This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature. C is by far the most common isotope, while only about one in a trillion carbon atoms is C C is produced in the upper atmosphere when nitrogen N is altered through the effects of cosmic radiation bombardment a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope.
The new isotope is called “radiocarbon” because it is radioactive, though it is not dangerous. It is naturally unstable and so it will spontaneously decay back into N after a period of time. It takes about 5, years for half of a sample of radiocarbon to decay back into nitrogen. It takes another 5, for half of the remainder to decay, and then another 5, for half of what’s left then to decay and so on.

Carbon is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer. C dating is only applicable to organic and some inorganic materials not applicable to metals. Gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry are the three principal radiocarbon dating methods. Radiocarbon measurements are reported as Conventional Radiocarbon Age. What is Radiocarbon Dating?
Jan 10, · Thousands of years later, if a bone from that animal is found, we can tell the age of the bone from the ratio of Carbon to Carbon in the bone. However, carbon dating can NOT be used for dating rock for two : Resolved.
Stable Isotopes Isotopes are different forms of an element that share the same chemical properties, but that differ in mass and the number of neutrons they contain. Common elements that possess isotopes include carbon, oxygen, hydrogen, and nitrogen. Each element has a specific identifier, like ‘C’ for carbon, while a number placed before it identifies the isotope e.
Some elements have many isotopes, but there are two basic types: Stable isotopes do not change over time while radioactive isotopes decrease or decay over predictable periods. To distinguish different isotopes from each other, scientists use special instruments called mass spectrometers.
Laboratory Staff and Students Principles of Stable Isotope Analysis Carbon and nitrogen isotope ratios in human bone may be used to reconstruct prehistoric diet because of differential fractionation, between certain plant groups, of atmospheric carbon dioxide during photosynthesis and of nitrogen during fixation or absorption. There are two stable isotopes each of carbon 12C, 13C and nitrogen 14N, 15N , with 12C and 14N by far the most common in nature.
Experimental data have indicated that different bone tissues reflect different components of the diet Ambrose and Norr ; Tieszen and Fagre
FLOURINE DATING: This method is adopted to date the ancient bones. The elements flourine in the form of fluorides occurs in the ground water. This fluoride is gradually absorbed and fixed in the phosphatic mineral matter of bones and teeth buried in the soil.
