As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale.To get to that point, there is also a historical discussion and description of non-radiometric dating methods.With this in mind geologist have long known that the deeper a sedimentary rock layer is the older it is, but how old?

With out individual time stamps the process of dating these structures could become extremely difficult.

To deal with many of these problems geologists utilize two types of geologic time: relative time and absolute time.

When geologists study layers of rocks, they get a glimpse of the past.

Determining the precise way that sedimentary rocks have layered throughout time gives them insight into how natural events have occurred.

Given the current status of direct chronometric dating methods for Arabian petroglyphs, it is rare that the precise age of a rock art panel can be determined.

However, all is not lost, and it is possible to establish a temporal sequence that can be quite edifying.

In archaeological terminology, there are two categories of dating methods: absolute and relative.

Absolute dating utilizes one or more of a variety of chronometric techniques to produce a computed numerical age, typically with a standard error.

In some ways, it is a natural record of the Earth's history.
