Although fossil dating is now more scientifically accurate, it still requires skill and experience as scientists have to make educated guesses based on any evidence and the dating available for the layers surrounding the fossils. The most common is U Rubidium—strontium dating This is based on the beta decay of rubidium to strontium , with a half-life of 50 billion years. What difficulties might paleontologists and archaeologists have when trying to find and date fossils? We define the rate of this radioactive decay in half-lives. Accuracy levels of within twenty million years in ages of two-and-a-half billion years are achievable. If scientists find the ratio of potassium to argon, it tells them how long the rocks have been around by how long the isotopes have been decaying. Over time, ionizing radiation is absorbed by mineral grains in sediments and archaeological materials such as quartz and potassium feldspar. Radio dating fossils

  1. At a certain temperature, the crystal structure has formed sufficiently to prevent diffusion of isotopes. Relative Dating The majority of the time fossils are dated using relative dating techniques. For all other nuclides, the proportion of the original nuclide to its decay products changes in a predictable way as the original nuclide decays over time.

  2. Such index fossils must be distinctive, globally distributed, and occupy a short time range to be useful. This process of material deposition and erosion as well as the rise and fall in the lake levels due to environmental changes slowly added layers to the geologic record found in the Turkana Basin.

  3. The radiation causes charge to remain within the grains in structurally unstable "electron traps".
