by carbon dating it is testing how much radioactivity is in carbon 14 because radio activity has a half life so how much radio activity is left then they can determine how old it is
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.
Geologists use fossils to determine the age of rocks through a process called biostratigraphy. They identify the specific group of fossils present in the rock layer, known as index fossils, that have a known age range. By comparing the index fossils to a geological time scale, geologists can estimate the age of the rock layer.
The study of strata is called stratigraphy. Stratigraphy can be used to determine an approximate age of fossils in rocks.
Scientists can determine the actual age of fossils using radiometric dating methods, such as carbon-14 dating for relatively young fossils or uranium-lead dating for older fossils. These methods measure the decay of radioactive isotopes in the fossil to calculate its age with a high degree of accuracy.
Fossils in rock layers can be used for relative dating, where older fossils are found in lower layers and younger fossils in higher layers. By comparing the fossils in different layers to known fossil sequences, scientists can estimate the age of the rocks. Fossils provide a timeline of life on Earth and can help determine the relative ages of rock layers.
scientist can determine a fossil's age in two ways: relative dating and absolute dating

because it is easier to find the age of fossils
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.

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.
Radiometric dating of fossils is not possible beyond roughly 70,000 years. However, when fossils are found in association with strata of volcanic and metamorphic rocks which can be dated radiometrically, a very accurate age of the fossils can be determined.
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.
