CRE ages of CM chondrites (top) (Krietsch et al. 2021) exhibit an increase on a cumulative histogram, i.e. a peak on a differential histogram. On the contrary, CV, CO, and CK chondrites (Scherer & Schultz 2000) exhibit a continuous distribution over the last 40 Myr. This increase/peak corresponds to the late miocene peak of extraterrestrial helium-3 in terrestrial sediments (Farley et al. 2006) (middle) and to the age of the CM-like Veritas family, (8.3 ± 0.1) Myr, as confirmed by convergence of orbits (bottom). A plot with a sum of probability distributions presented in Krietsch et al. (2021), Fig. 9 is misleading; uncertainties of old CRE ages are large, the probability is low, it seems like there are ‘none’ meteorites having old CRE ages. On the contrary, our cumulative histogram demonstrates that there are numerous meteorites with old CRE ages.
