We wouldn’t be dating the artifact – we’d be dating the rock and the rock might have formed millions of years earlier.
Accurate dates also allow us to create sequences of evolutionary change and work out when species appeared or became extinct. These are: Where possible, several different methods are used and each method is repeated to confirm the results obtained and improve accuracy.
Different methods have their own limitations, especially with regard to the age range they can measure and the substances they can date.

Any alteration or fracturing means that the potassium or the argon or both have been site also must be geologically meaningful, clearly related to fossil-bearing rocks or other features that need a good date to join the big story.
