Perhaps by carbon dating and by comparing with the evolution and dominance of various organisms in the geological time scale.

What are index fossils and how are they used to determine the absolute age of sedimentary rock?
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.
How do scientists use sedimentary rock to determine a fossils relative age?
Scientists use sedimentary rock to determine a fossil relative age by studying the rock.
What is examined to do relative dating?
The position of fossils in sedimentary rock layers.
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
Why would a scientist use both relative and absolute dating?
They both help you understand fossils

Fossils that can be used to establish relative dates are most likely to be found in?
sedimentary rocks.
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.
Do index fossils tell the relative or absolute age of fossils?
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.
What is examined to do relative dating?
The position of fossils in sedimentary rock layers.
How can fossills be used to determine the relative ages of rock 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 are two ways geologists determine the age of fossils?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
What two things did 19th century scientists do to determine the relative age of sedimentary rock all over the world?
They studied fossils and applied the principle that old layers of rock are below young layers! -
How does relative dating and absolute dating help scientists assemble a fossil record for an area?
Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age Absolute dating is the process of determining an approximate computed age in archaeology and geology.
