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.

∙ 9y agoThere are two main methods for dating fossils. The first is relative dating which examines the layers of rock around the fossil to find an approximate date. The other is absolute dating, which measure the decay of carbon atoms.

What information must first be obtained before the scientists can place the fossils in the ancestral time line of the dog?
"The age of the fossils
What can be used to date fossils in rocks to give an approximate age.?
The study of strata is called stratigraphy. Stratigraphy can be used to determine an approximate age of fossils in rocks.
Used to date fossils in rocks to give an approximate age?
Radiocarbon Dating.
What are two kinds of information that scientists attempt to infer from the study of fossils?
Relative age of the rocks and the Paleo environment.
To determine the absolute age of rocks and fossils geologists use?
They would look for evidence of index fossils, those of certain rapidly evolving creatures that lived during a specific time period. This method is called relative dating. For a closer estimation they would be able to date the rock using radiometric techniques that base its age on the degree of isotope decay . This method would reveal the much more specific absolute age.
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 the age of plant and animal fossils is determined?
The age of a plant or animal in a fossil is determined by radiocarbon dating. This means scientists measure the amount of a special type of carbon in the fossil, to determine the date.

How do archaeologists date fossils?
Scientists take samples of the carbon remaining in the fossil. They then use a form of carbon dating to determine its age. (it doesn't have to be a fossil, it could be any ancient remain, even a skull from fifty years ago, or a plate from the 1700's. Just wanted to clarify that a little bit more!)
Which of these scientists contributed to evolutionary theory through the study of geology, fossils, and age of the earth?
Lyell
How do geologists use index fossils to determine rock age?
Index fossils, also known as zone or guide fossils, help date strata and sediment to determine the age of entrapment. The best index fossils are those that were abundant , common, and short lived.

How do you tell which fossils are older?
Fossils found in deeper rock layers are typically older than those found in shallower layers. Scientists also use methods like radiometric dating to determine the age of fossils based on the decay of radioactive isotopes present in the fossils. Additionally, studying the index fossils that are typically associated with specific time periods can help determine the relative age of fossils.
