In the published manuscript, the study presents diverse geochronological and biochronological data providing age constraints on the site of Tsiotra Vryssi (Mygdonia basin, Greece). One of the methods presented is based on burial ages from cosmogenic radionuclides. Table 2 of this study reports cosmogenic simple burial ages of 1.88 ± 0.16 Myr, 2.10 ± 0.18 Myr, and 1.98 ± 0.18 Myr (for samples COSMO 1, 2, and 3, respectively). However, after publication of the manuscript, a small error was found in the calculation of these ages. In particular, it concerns a typo in the MatLab code resulting in a too-low value for the fast muonic 10Be production rate, which affected the last column of Table 2 with the simple burial ages. After correcting this mistake, the ‘corrected’ simple burial ages in Table 2 (as well as in Figure 9) should be 1.54 ± 0.10 Myr, 1.75 ± 0.10 Myr, and 1.62 ± 0.10 Myr. These ages, as were the original published ages, are the minimum possible burial ages from this technique. Therefore, the deposit with normal polarity containing the cosmogenic samples is attributed to the Olduvai subchron (1.95–1.78 Myr). The age of the overlying layer showing a reverse polarity and containing the vertebrate fossils is therefore the same as was originally published (<1.78 Myr), and overall, an age between 1.78 and ~1.5 Myr is proposed for the Tsiotra Vryssi fauna. We emphasize that the corrected ages mentioned here do not change the interpretations of the Konidaris et al. 2021 study, and we present this Erratum so that future studies using these data have access to the corrected values.
