The black arrow points to one good example, but there are several others. This change is called radioactive decay. As a result, xenoliths are older than the rock which contains them. Geologists have studied the order in which fossils appeared and disappeared through time and rocks. The principle states that any geologic features that cut across strata must have formed after the rocks they cut through Figures 2 and 3. Relative Dating The first method that scientists use to determine the age of rocks is relative dating. It is composed of rocks and sediments deposited over millions of years. Fossil assemblage B includes the index fossils the orange ammonite and the blue ammonite, meaning that assemblage B must have been deposited during the interval of time indicated by the red box. The dinosaur is called superus awesomus. Geologists still use the following principles today as a means to provide information about geologic history and the timing of geologic events.

  1. Layers of sedimentary rock extend sideways in the same order. As organisms exist at the same time period throughout the world, their presence or sometimes absence may be used to provide a relative age of the formations in which they are found.

  2. However, the age of each fossil primate needs to be determined so that fossils of the same age found in different parts of the world and fossils of different ages can be compared. Most sedimentary rocks are laid down in flat horizontal layers, although these can later tilt and fold. In many respects they are analogous to fluid inclusions.

  3. Most of the soft tissues of the human body get decomposed with only the hard tissues left for research. Later, when radiometric absolute dating methods were developed, they still were not applicable to sedimentary layers. Paul says he can tell from the fossils that superus awesomus lived on Earth about million years ago.
