A comparison between the model ages of lunar craters with diameter D  >  20 km and those of 118 lunar glasses taken from Apollo regolith samples. The craters ages are from Figure 2, while the ages for the glasses are provided by R. Ghent et al. (2021). We represent the mean age and 1σ age uncertainties as Gaussians distributions, with all of the distributions added to produce the observed distribution. Notable age spikes are observed around 800 Ma in both distributions, along with an increase in events over the past 300 Myr or so.
