Absolute dating fossils
Using these methods, the scientist determines a date range for when an event took place rather than where it fits in the overall record. The techniques scientist need for absolute dating did not become available until the later half of the 20th century.
Absolute dating uses clues, such as the emperor's face on a coin, to date an artifact.
Finding complete fossils like this is even rarer than finding parts of organisms.
Once a fossil has been found, then the age of that fossil needs to be determined. These are called relative dating and radiometric dating.

Chronometric or calendar dating is a better choice.
Tree ring dating offers over 1,000 years of clues in dates of artifacts from the American Southwest.
Radiocarbon dating provides additional clues necessary for absolute dating.
For really old dates we need to use radioactive isotopes.Fossils can give clues to the past and history of life on Earth.While the fossil record is incomplete, it still helps lend evidence to the Theory of Evolution.In a year with a long growing season the tree ring for that year will be thick.If there wasa very long winter then there will be a thinner tree ring.
