Analysis of mammalian species composition has been performed for eight archaeological sites on the Ustyurt plateau. They date to the range from the middle Subboreal to the middle Subatlantic. The modern species composition of large mammals formed by the end of the Middle Holocene (Subboreal 2) and did not change until the early 20th century. The ungulate species composition and ratio on the plateau showed geographical variation and changed over time. Boars were always rare or absent in the north of Ustyurt. The structure of the ungulate fauna in the north of Ustyurt changed over time. Onager numbers in this area increased and saiga numbers decreased in the middle of the Late Holocene. Significant geographical differences in the structure of ungulate fauna were recorded in the middle of the Late Holocene. The numbers of onagers, goitered gazelles, and argali were higher, whereas the numbers of saigas were lower in the south of Ustyurt than in the north.
