Raw time-series plots from age histograms at 10 Ma intervals, regional weighting of ages, and U–Pb records accepted with absolute discordance <70 Ma and 2σ uncertainty <70 Ma (after Condie and Puetz (2019). (a) U–Pb igneous zircon ages (n = 180 412); (b) U–Pb detrital zircon ages (n = 501 938); (c) Large Igneous Province (LIP) ages represented by 535 crustal provinces (no regional weighting, smoothed with 3-weight Gaussian kernel). U–Pb zircon age peaks match intervals of supercontinent assembly (pale green), whereas troughs correspond to intervals of supercontinent tenure (generally white) and break-up (pale brown) (after Condie and Aster 2010; Condie 2014). Major current and proposed chronostratigraphic boundaries (Fig. 1c) at c. 2450, 1800, 1000, 540, 252 and 66 Ma follow zircon abundance peaks.
