Abstract
The species composition of the mid-Early Pleistocene fauna in northwestern Azerbaijan has been elucidated through the analysis of fossil material recovered from the Palan-Tyukan site. This research also included a review of the relevant literature. The paleontological material has been fossilized to a similar extent, indicating similar burial conditions. Animal bones at the site were accumulated during a single sedimentation cycle in sediments of what was once a shallow, heavily silted body of water with slow-flowing or standing water. We have identified 16 species of large mammals, whose presence has allowed us to determine the time period in which this faunal complex existed, as well as the characteristics of the natural environment at the time of its formation. The order Carnivora is represented by 10 individuals, the order Proboscidea by 2 individuals, the order Perissodactyla by 3 individuals, and the order Artiodactyla by 18 individuals. The Palan-Tyukan paleo-landscape can be described as a mosaic of different environments. Flat riverine areas with dense vegetation gradually transitioned into the hilly steppe with mixed vegetation of varying densities. Our reconstruction of the paleogeographic environment indicates that large mammals of Palan-Tyukan lived there under conditions of a relatively humid subtropical climate. The Palan-Tyukan faunal complex belongs to the Mediterranean palaeobiogeographical subregion, biozone MNQ18, at the beginning of the Late Villafranchian period, and falls within the time interval from 1.93 to 1.77 million years ago.
