Dating Fossils - How Are Fossils Dated?
Unanswered Questions. Wiki User Body fossils and trace fossils are the principal types of evidence about ancient life, and geochemical evidence has helped to decipher the evolution of life before there were organisms large enough to leave fossils.
Estimating the dates of these remains is essential but difficult: sometimes adjacent rock layers allow radiometric dating, which provides absolute dates that are accurate to within 0.
Classifying ancient organisms is also difficult, as many do not fit well into the Linnean taxonomy that is commonly used for classifying living organisms, and paleontologists more often use cladistics to draw up evolutionary "family trees".
The final quarter of the 20th century saw the development of molecular phylogenetics, which investigates how closely organisms are related by measuring how similar the DNA is in their genomes. Molecular phylogenetics has also been used to estimate the dates when species diverged, but there is controversy about the reliability of the molecular clock on which such estimates depend.

Asked in Fossils What are two ways of using fossils to date organisms? Asked in Geology What are the two ways to date a fossil? Radioactive isotope dating potassium, argon and relative dating, comparing with fossils of the same characteristics with known dates. Particularly if they are known to be 'zone fossils'. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
Relative Dating The majority of the time fossils are dated using relative dating techniques. Using relative dating the fossil is compared to something for which an age is already known. For example if you have a fossil trilobite and it was found in the Wheeler Formation.
Two main ways of dating fossils
The Wheeler Formation has been previously dated to approximately million year old, so we know the trilobite is also about million years old. Scientists can use certain types of fossils referred to as index fossils to assist in relative dating via correlation. Index fossils are fossils that are known to only occur within a very specific age range.
There are two main methods for dating fossils. The first is relative dating which examines the layers of rock around the fossil to find an approximate date. The other is absolute dating, which.

Related QuestionsMore Answers Below/ From dinosaurs to neanderthals, fossils are integral to the accurate dating of life's time line on the planet. According to "Enchanted Learning," archaeologists use three main types of fossil: the true form fossil, trace fossil and mold fossil; a fourth type is the cast fossil. Fossilization can take millions of years to occur.
Typically commonly occurring fossils that had a widespread geographic distribution such as brachiopods, trilobites, and ammonites work best as index fossils. If the fossil you are trying to date occurs alongside one of these index fossils, then the fossil you are dating must fall into the age range of the index fossil. Sometimes multiple index fossils can be used. In a hypothetical example, a rock formation contains fossils of a type of brachiopod known to occur between and million years.
The same rock formation also contains a type of trilobite that was known to live to million years ago. Since the rock formation contains both types of fossils the ago of the rock formation must be in the overlapping date range of to million years. Studying the layers of rock or strata can also be useful. Layers of rock are deposited sequentially.
If a layer of rock containing the fossil is higher up in the sequence that another layer, you know that layer must be younger in age.
This can often be complicated by the fact that geological forces can cause faulting and tilting of rocks. Artifacts with the greatest cultural impact are considered major works.
Artifacts with less cultural significance are considered minor.

Palaeontologists, people who study fossils, divide them into two major types - body fossils and trace fossils.
The first type, body fossils, are the fossilised remains of an animal or plant, like bones, shells and leaves. These can be mould and cast fossils, like most of the fossilised dinosaur skeletons and big bones we see, replacement fossils, like petrified wood, or whole body fossils - mammoths caught in ice, or insects trapped in amber. The second type of fossil records the activity of an animal.
