Doing this, one can "map" out where the fossil appeared in the geographic time scale and thus work out a rough estimate of the fossil's age, by comparing it to other fossils (i.e "it came before this fossil, and after this fossil, so therefore it must be an intermediary, and will have appeared in the time period between the two other fossils," or "this fossil was found in the same stratum as this other one, at almost the same depth and in a close radius of each other - therefore, they must have appeared in the same time period.") Perhaps the most concerning shortcoming of relative dating is how it is incapable of determining an exact or absolute age. The eruption was so intense that many layers of sediment on the volcanic mountain were blown into the air, and settled on the landscape around the volcano. It is a gaurantee that different scientists, from different backgrounds, have locked horns over this debate many times, each with their own sets of recorded evidence. Each technique has already been discussed in detail above. Radiometric Pros From the above list, it can be seen that both techniques have pros and cons.In fact, some are of the opinion that its results are actually more of a rough estimate or less trustworthy than the results obtained from radioactive dating. Because the results rely heavily, not necessarily on the position of the fossil or its stratum (which is still an extremely important primary factor), but rather the way in which the scientist interprets it, which means it is vulnerable to bias, miscalculations, and so on. Both are not entirely inaccurate, but neither are both entirely accurate.

Without relative and radiometric dating techniques, no one would know whether dinosaurs lived 5,000 or 150,000,000 years ago.Relative dating is the technique that attempts to roughly determine the age of a fossil using its position or location in relation to other fossils or remains in nearby strata (hence the name, "relative") In other words, to determine the age of a fossil using relative dating, one would look at the stratum the fossil was found in. In fact, it may contain coal or fossil fuels - which take, at the very least, thousands of years to form - that now appear near the very top!Then, one would compare the fossil's position in the stratum to the position of other nearby index fossils or remains. Such an inconsistency would, logically, confuse geologists in the future if they had no prior knowledge of the St. It is known that volcanic eruptions, such as the one at St. Not only that, but earthquakes and floods can also sometimes shift and mix strata and sediments.Therefore, scientists need to make use of proper techniques to adequately specify what the age of a fossil or artifact is.Two of the most well-known and most frequently used include radioactive dating and relative dating. Organic bodies, such as you and me, as well as inanimate objects, such as stone tablets or rocks.If a fossil is found, it means it is organic in nature, and thus has or will have contained C-14 atoms.

For example, in decomposing organic bodies - such as an animal carcass - carbon-14, an isotope of carbon, is present.

Overtime, the C-14 atoms give off radiation, and, eventually, transform into nitrogen-14 atoms.

Phrased simply, radioactive dating is the method that uses measurements relating to the radioactivity of the atoms in a fossil or an artifact. What "decay" means is that the atoms in the object or body become unstable, and, over time, begin to "decompose" by giving off radiation in the forms of subatomic particles (such as electrons and protons).
