Fossils themselves can very rarely be dated by any means...their age is usually judged by the geological assessment of the area and layer in which they are found

What two methods are used to determine the age of a rock?
The two methods are relative dating and radioactive dating for fossils. I think it's the same for rocks.
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 are two ways geologists determine the age of fossils?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
How are stratigraphic and radioactive dating different in regards to how they date fossils?
Radioactive dating refers to the process of measuring the age of an object using the amount of a given radioactive material it contains. Relative dating, meanwhile, measures the order of past events, without determining their absolute age.
Why are index fossils so important to geologists?
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
What are two of determining a fossils age?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
How can the absolute age of a rock be determined?
Through Radioactive Dating or Isotopic Dating.
What are the fallacies of fossil dating?
One of the biggest fallacies of fossil dating is that they use the rock layer to help determine the age of the fossils, but the fossils are also used to help determine the age of the rock layer.
How does relative dating enable palenteologists to estimate a fossils age?
by comparing its placement with that of fossils in other layers of rock
Used to date fossils in rocks to give an approximate age?
Radiocarbon Dating.
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.
Why do scientist find relative dating easy?
because it is easier to find the age of fossils
Fossils around 1000000 years old likely to be dated?
relitive-age dating
What is the function of radioisotopes C-14?
Used in carbon dating that is to find the age of fossils.
Radiocarbon dating would be useful in dating the age of the earth?
Radiocarbon dating is not typically used to determine the age of the Earth because it can only accurately date organic materials up to around 50,000 years old. Other dating methods, such as radiometric dating of rocks and minerals, are used to estimate the age of the Earth, around 4.5 billion years.
Can radiocarbon dating be used to determine the age of pottery?
No. radio carbon dating is only efficient for the fossils of plants or animals. As pottery is an abiotic substance its age cannot be determined by carbon dating
What types of dating estimates the age of a rock or fossil?
The rough estimating of the age of a fossil or rock containing fossils is called relative dating, and is based on the position of the rock or fossil in undisturbed sedimentary strata which contains what are called 'index fossils', fossils that only appear in specific geologic time periods.
