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.

What is the function of radioisotopes C-14?
Used in carbon dating that is to find the age of fossils.
Why do scientist find relative dating easy?
because it is easier to find the age of fossils
How do scientist find the age of fossils today?
They find out by have sexual intercourse with them and see how their reproductive organs are working.
What are the radioisotopes used in forensic science?
the radioisotopes are used to determine age of the deceast.
A scientist identifies a variety of fossils in a layer of sedimentary rock By applying the principle of fossil succession the scientist can identify?
The age of the rock layer
How do fossils help scientist?
Fossils help scientists by leaving a record for scientists to use. Fossils can help show a scientist which type of animal was living in an area during a certain time. This gives scientists a better idea of what that area was like hundreds of millions of years ago all the way through today.
How do scientists determine history by using fossils and sedimentary layers?
Geologists and paleontologists look for index fossils in rock strata. These index fossils appear only in rocks of a certain age. Finding them lets the scientist know the approximate age range of a rock formation. Layers of sedimentary rock will also aid the scientist is determining the climate from that age, of any volcanism that may have taken place, the lifeforms that existed, and even find evidence of catastrophic events such as asteroid collisions that may have led to extinction events.
How do geologists use fossils to determine rocks age what are this fossils called?
they find the hard part of the fossil
What is the primary technique for determining the absolute age of a rock?
well its do to the sediment in a rock by it layering
How do scientist use radioactive elements to determine the actual age of fossils?
scientist can determine a fossil's age in two ways: relative dating and absolute dating
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.
How can fossils be used to date the rock in the strata?
Because index fossils are useful because they tell the relative ages of the rock layers in which they occur. They also tell what year they were made.
