If rocks of unknown age have traces of E. Paleontologists rely on stratigraphy to date fossils. A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved. Elsevier There are several different methods for estimating the ages of fossils, including:. A method of estimating the age of an artifact or biological vestige based on the relative amounts of various isotopes of carbon present in a sample.

The amount of time it takes for half of the parent isotopes to radioactively decay to daughter isotopes. The study of rock layers and the layering process. However some isotopes, like 14 C, have an unstable nucleus and are radioactive. For example, unstable 14 C transforms to stable nitrogen 14 N. The use of various radioisotopes allows the dating of biological and geological samples with a high degree of accuracy.

By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.

How Do Scientists Date Ancient Things?

The study of strata and their relationships thermoluminescence: Because the half-life of carbon is 5, years, it is only reliable for dating objects up to about 60, years old. However, once rocks or fossils become much older than that, all of the "traps" in the crystal structures become full and no more electrons can accumulate, even if they are dislodged. Because they are often rare, primate fossils are not usually good index fossils. For example, unstable 14 C transforms to stable nitrogen 14 N. In this figure, the unknown fossil, a red sponge, occurs with five other fossils in fossil assemblage B.
