! Start, million years ago<ref name="uncertain-dates">Dates are slightly uncertain with differences of a few percent between various sources being common. This is largely due to uncertainties in [[radiometric dating]] and the problem that deposits suitable for radiometric dating seldom occur exactly at the places in the geologic column where they would be most useful. The dates and errors quoted above are according to the [[International Commission on Stratigraphy]] 2004 time scale. Dates labeled with a * indicate boundaries where a [[Global Boundary Stratotype Section and Point]] has been internationally agreed upon: see [[List of Global Boundary Stratotype Sections and Points]] for a complete list.</ref>
