The location of Late Sarmatian vertebrate fossils near Pocsesti village, Orhei district, was discovered in 1975. Here, above the Bessarabian marine sediments, there is a stratum of sandy-clay formations belonging to the "Balta Formation", represented by alluvial and lacustrine deposits, widely spread to the south of Chisinau. According to paleomagnetic data, the osseous rocks have normal magnetization and belong to the 9th chron of magnetic polarity, which corresponds to the first half of the Late Sarmatian (Early Charsonian, 9.8 million years; MN 10). Terrestrial vertebrate remains were found in sandy and lumpy clays, forming a lens-shaped assemblage that varies in thickness from 0.3 to 0.7 m. The sorting of bone material is weak, indicating its rapid burial. Based on the study of faunistic composition Prof. Lungu A.N. singles out the fossil fauna of this locality into an independent complex - Poksheshtsky, characterizing the fauna of the Late Sarmatian. The composition of the Poksesti faunal complex: Amphibia: Hyla sp., Bombina sp.; Reptilia: Protestudo sp.; Aves: Strutio sp.; Mammalia: Lagomorpha - Proochotona cf. calfina Lungu, 1981; Alilepus sp.; Rodentia - Neocricetodon (Kowalskia) sp., Collimys sp.; Carnivora - Parataxidea sp., Proictherium aff. tauricum (Borissiak, 1915), Dinocrocuta (Percrocuta) gigantea (Schlosser, 1903), Metailurus cf. parvulus., Machairodus sp. (cf. M. giganteus) (Wagner, 1854); Cetacea: Physeteroidea indet.; Proboscidea – Tetralophodon longirostris Kaup, 1832; Perissodactyla - Hippotherium aff. verae Gabunia, 1979; H. giganteum (Gromova, 1952); Chilotherium (Acerorhinus) cf. zernovi Borissiak, 1915; Ch. (Ch.) aff. sarmaticum Korotkevich, 1958; Artiodactyla Achtiaria aff. moldavica Godina, 1979; Gazella (Miogazella) schlosseri Pavlow, 1913; Gazella aff. deperdita Gaudry, 1848; Tragoportax leskevitski (Borissiak, 1915), Tragoportax sp.; Cetacea: Delphinidae gen. et sp. indet.; Physeteroidea indet. (Scaldicetus caretti?); Sirenia: conf. Metaxytherium. New data on the fossil fauna from Poksesti and data on geology and taphonomy, suggest the presence of a semi-marine or marine sedimentation environment, corresponding to the near-adjacent zone of a large river system with spits and rifts.
