Nikitin et al. 2022, p. 3: "Established dating, based on material culture, such as the presence of imports of ceramics from securely dated chronological periods, as well as radiometric radiocarbon dates on charcoal, pottery, and animal bone, primarily from the ditches of the Mayaky sanctuary (Table S1a), place the Usatove culture in the chronological period corresponding to ca. 3650-2740 BCE".

Nikitin et al. 2022, p. 12: "Taken together, the late 5th millennium Eneolithic dates obtained on human remains, whether or not affected by a RE [reservoir effect], as well as the finds of Trypillian A-BI period ceramics at Mayaky (Petrenko, 2009), corroborate the existence of proto-Usatove burials at the Mayaky complex, not readily distinguished in the field from the late Eneolithic Usatove burials".
