I don't really know how it works or what it entails, but there's a process called carbon dating that's frequently mentioned to determine the age of various objects. I'm not sure exactly, but it involves determining the half-life of one of the elements in the fossil, and then determining how long ago it started to decay.
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.
True. Fossils can be dated using both relative dating methods, which determine the sequence of events in which fossils occurred, and absolute dating methods, which rely on radioactive isotopes to calculate the age of fossils.
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.
Radiometric dating is used to determine the age of fossils in rocks by measuring the decay of radioactive isotopes, such as carbon-14 or uranium-238, in the fossil. By comparing the amounts of the parent and daughter isotopes present in the fossil, scientists can calculate the age of the fossil. This method provides an approximate age of the fossil based on the rate of radioactive decay.
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.

Radiometric dating works to determine the age of rocks and fossils by measuring the decay of radioactive isotopes within them. This decay occurs at a constant rate, allowing scientists to calculate the age of the sample based on the amount of remaining radioactive isotopes.
Radiometric dating measures the decay of radioactive isotopes in rocks and fossils to determine their age. By comparing the ratio of parent isotopes to daughter isotopes, scientists can calculate the age of the sample based on the known rate of decay for that particular isotope.
True. Fossils can be dated using both relative dating methods, which determine the sequence of events in which fossils occurred, and absolute dating methods, which rely on radioactive isotopes to calculate the age of fossils.
Isotopic dating is a method used to determine the age of rocks and fossils by analyzing the decay of radioactive isotopes within them. By measuring the ratio of parent isotopes to daughter isotopes, scientists can calculate the age of the sample. This technique is based on the principle that certain isotopes decay at a constant rate over time, allowing researchers to accurately date rocks and fossils.

Radioactive dating is used to determine the age of rocks and fossils by measuring the decay of radioactive isotopes within them. By comparing the amount of parent and daughter isotopes present, scientists can calculate the age of the sample. This method relies on the predictable rate of decay of certain isotopes, such as carbon-14 or uranium-238, to estimate the age of the material.
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.
Index fossils are used to date rocks by correlating the fossils found in the rock layers with known ages of those fossils. Index fossils are distinctive, widespread, and lived for a relatively short period of time. By identifying these fossils in a rock layer, scientists can infer the age of the rock based on the age range of the known fossil.

This process relies on the principle that certain isotopes decay at a known rate over time, allowing scientists to calculate the age of the sample based on the amount of remaining radioactive isotopes.
