NettetSome very straightforward principles are used to determine the age of fossils. Students should be able to understand the principles and have that as a background so that age determinations by paleontologists and geologists don't seem like black magic. There are two types of age determinations. NettetRelative dating: We can determine the relative age of fossils by comparing their position in rock layers. Fossils that are found in lower layers are older than those found in higher layers. Radiometric dating: This method measures the decay of radioactive isotopes in fossils (such as Carbon-14 or Uranium) to determine their age. NettetAge determinations using radioactive isotopes are subject to relatively small errors in measurement--but errors that look small can mean many years or millions of years. If the measurements have an error of 1 percent, for example, an age determination of 100 million years could actually be wrong by a million years too low or too high. fort hood training holidays 2023
