Other critics, perhaps more familiar with the data, question certain aspects of the quality of the fossil record and of its dating.These skeptics do not provide scientific evidence for their views.From the mapped field relationships, it is a simple matter to work out a geological cross-section and the relative timing of the geologic events.His geological cross-section may look something like Figure 2.They are: (1) the C14 concentration in a specimen at its time of death; (2) the decay rate of C14; (3) the current C14 concentration in the specimen being “dated”; and (4) if anything else has affected the specimen’s C14 content. The curved line represents the declining amount of C14 atoms over time due to radioactive decay.Note: only the third of those four necessary facts can be measured, the other three must be estimated, assumed, or extrapolated. During each half-life (~5,730 years), about half of the remaining C14 atoms in a specimen are expected to decay.Clearly, Sedimentary Rocks A were deposited and deformed before the Volcanic Dyke intruded them.

By looking at other outcrops in the area, our geologist is able to draw a geological map which records how the rocks are related to each other in the field.

Early geologists, in the 1700s and 1800s, noticed how fossils seemed to occur in sequences: certain assemblages of fossils were always found below other assemblages. Since 1859, paleontologists, or fossil experts, have searched the world for fossils.

In the past 150 years they have not found any fossils that Darwin would not have expected.

by Tas Walker A geologist works out the relative age of a rock by carefully studying where the rock is found in the field.

The field relationships, as they are called, are of primary importance and all radiometric dates are evaluated against them.
