Figure 4: In the example, 14 C is the parent and 14 N is the daughter. Using the overlapping age ranges of multiple fossils, it is possible to determine the relative age of the fossil species i. Chemical substances that cannot be split into a simpler substances fault: Sincepaleontologists, or fossil experts, have searched the world for fossils.

Faure, G. The discovery of means for absolute dating in the early s was a huge advance. Older dates may change by a few million years up and down, but younger dates are stable. Tectonic activity left some areas of land upliftedand erosional forces from the lake, nearby rivers, and other forms of weathering exposed rock, even older rock layers, as outcroppings in the landscape. Doing this helps paleontologists maintain accurate records and piece together the story of human history. Geologists and paleontologists are highly self-critical, and they have worried for decades about these issues.
