Key Points Determining the ages of dating is an important step in mapping out how life evolved across geologic time. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years.

Carbon dating, or other objects based on a rock that they find their ages. Certain organisms are only found during certain times and if a fossil of one of these organisms is found then you can determine the relative age of the fossil. To use relative dating, you need to look at the order each rock layer was deposited.

For example, there is a specific interval of time, indicated by the red box, during which both the blue ammonite estimate orange ammonite co-existed.
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. If the fossil was found in a location that has a known date, this can help to identify the age of the fossil. If a fossil is found next to an index fossil, it can be assumed that the fossil is a similar age. Fossils need to be clean in order for carbon dating to be accurate.
