Stratigraphy, the relative positon of fossils in a sediment bed, is a common method. Assuming the beds lie in their natural position.
Dating by using radioactive decay is another method used mainly for sub-fossil material such as archaeological artifacts; or for materials of geological age.

Do fossil records help to date fossils?
Fossil records contain radiation, and the older the fossil is, the less radiation it gives off. Scientists study how much radiation is in the fossil record, and they find out how old the earth is.
How do scientists date fossils and artifacts?
Dating fossils and artifacts are easy. Scientist can look and tell how old the fossils by how many layers is under it.
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.
How long have moths been on earth?
It is not known exactly how long the moth has been on earth. However, fossils of moths have been found that date back more than 190 million years.
What do scientists use to date exact age of fossils?
For relatively recent fossils, dating by carbon 14 is the most accurate method. For older fossils it is necessary to analyse the geological layer in which they are found; fossils located in an undisturbed geological layer of a certain age, are the same age as the layer in which they are found, necessarily.
What is the age of the oldest cyanobacteria fossil found?
The oldest known cyanobacteria fossils are known as stromatolites and fossils have been found that date back 2.72 billion years old. More recent discoveries however suggest that cyanobacteria may date back as far as 3.5 billion years into Earth's past.
How do scientists date the fossils and artifacts?
any other artifact or geological strata and compare it. Go to tables with similar artifacts.
When were constellations found by scientists?
They were all found at different times, there is no exact date
What geologists able to tell archaeologist about fossils?
How do archaeologists date fossils ? archaeologist can date fossills by seeingf how deep down it is in the ground [ checking how many layers ] , scientists can use radio-active dating, and compare a fossil that they know the exact date that it was from compare the looks and tell by that

What is the usage of the geological time scale?
The use of it is so they can date all of the fossils and stuff for scientists to study and see what it was like in the past.
Where did they find the pegomastax dinosaur?
Pegomastax was found in South Africa. Its fossils date to the early Jurassic.
