Fig. 6: The 59 crater ages in descending order.

The estimated ages of 59 craters based on the constant flux model and the 800 Ma spike model are shown in descending order. In both models, it is obvious that the slopes of the lines less than a few million years and ~800 Ma are gentler than those of other eras (e.g., 300–660 Ma and/or >800 Ma), suggesting the recent increase in impact flux forming the large craters (D > 20 km).
