Carbondating is the method often used to date fossils, and that involves both the elements Carbon-12 and Carbon-14.
What else can I help you with?
What are index fossils and how are they used to determine the absolute age of sedimentary rocks?
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
Can fossils be used to determine the relative ages of rocks layers?
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.
What can be used to date fossils in rocks to give an approximate age?
The study of strata is called stratigraphy. Stratigraphy can be used to determine an approximate age of fossils in rocks.

How is carbon dating used to determine the age of dinosaur fossils?
Carbon dating is not typically used to determine the age of dinosaur fossils because dinosaurs lived millions of years ago, beyond the range of carbon dating which is effective up to about 50,000 years. Instead, other methods like radiometric dating are used to determine the age of dinosaur fossils by measuring the decay of radioactive isotopes in the fossils.
What are index fossils and how are they used to determine the absolute age of sedimentary rock?

How is carbon-14 dating used to determine the age of dinosaur fossils?
Carbon-14 dating is not used to determine the age of dinosaur fossils. Instead, scientists use other methods like radiometric dating, such as uranium-lead dating or potassium-argon dating, to estimate the age of dinosaur fossils. These methods rely on the decay of radioactive isotopes in the fossils to calculate their age.
What are index fossils used to determine?
Index fossils are used to determine the relative age of rock layers. By studying the presence of these distinct fossils in different layers of rock, geologists can identify the relative age of the rocks and correlate them with other rock layers in different locations.
What property of radioactive isotopes allow them to be used to determine the age of rocks and fossils?
Their half life.
How fossils can be used to determine the absolute and relative age of a sedimentary rock layer?
Perhaps by carbon dating and by comparing with the evolution and dominance of various organisms in the geological time scale.
