The Age of Dinosaurs was so many millions of years ago that it is very difficult to date exactly. Scientists use two kinds of dating techniques to work out the age of rocks and fossils. The first method is called relative dating. This considers the positions of the different rocks in sequence in relation to each other and the different types of fossil that are found in them. The second method is called absolute dating and is done by analysing the amount of radioactive decay in the minerals of the rocks.

Smith is known as the Father of English Geology. Oxford Library. Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods. Some critics, particularly religious fundamentalists, argue that neither fossils nor dating can be trusted, and that their interpretations are better. 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. Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data. The rejection of the validity of fossils and of dating by religious fundamentalists creates a problem for them:. Fossil sequences were recognized and established in their broad outlines long before Charles Darwin had even thought of evolution. Early geologists, in the s and s, noticed how fossils seemed to occur in sequences: The first work was done in England and France. Then, geologists began to build up the stratigraphic column, the familiar listing of divisions of geological time — Jurassic, Cretaceous, Tertiary, and so on.
What are the two methods of dating rocks and fossils
Archaeological finds worldwide have helped researchers to fill out the story of human evolution and migration. An essential piece of information in this research is the age of the fossils and artifacts. How do scientists determine their ages? Here are more details on a few of the methods used to date objects discussed in "The Great Human Migration" Smithsonian , July In a cave in Oregon, archaeologists found bones, plant remains and coprolites—fossilized feces. DNA remaining in the coprolites indicated their human origin but not their age. For that, the scientists looked to the carbon contained within the ancient dung.

Dating Fossils – How Are Fossils Dated?
The age of fossils can be determined using stratigraphy, biostratigraphy, and radiocarbon dating. Paleontology seeks to map out how life evolved across geologic time. A substantial hurdle is the difficulty of working out fossil ages. There are several different methods for estimating the ages of fossils, including:. Stratigraphy is the science of understanding the strata, or layers, that form the sedimentary record. Strata are differentiated from each other by their different colors or compositions and are exposed in cliffs, quarries, and river banks. These rocks normally form relatively horizontal, parallel layers, with younger layers forming on top.
