Relative absolute dating differences

Sometimes sedimentary rocks are disturbed by events, such as fault movements, that cut across layers after the rocks were deposited.

However, by itself a fossil has little meaning unless it is placed within some context.The layers of rock at the base of the canyon were deposited first, and are thus older than the layers of rock exposed at the top (principle of superposition).In the Grand Canyon, the layers of strata are nearly horizontal.Second, it is possible to determine the numerical age for fossils or earth materials.Numerical ages estimate the date of a geological event and can sometimes reveal quite precisely when a fossil species existed in time.

The age of the fossil must be determined so it can be compared to other fossil species from the same time period.
