摘要

摘要充分考虑了从更新世Sanmanych地区（46°24′53〃N，42°36′25〃E）获得的地质、古兽相学和软体动物学资料。微咸水软体动物的组成表明，该含骨系列应与早期赫瓦利阶海侵有关。化石记录让我们得以深入了解里海海水冲破曼尼奇凹陷进入黑海盆地时的古环境。动物区系的证据表明干旱的环境和凉爽的气候。啮齿动物的种类组成相当差；它只包括指示开放环境的物种，这表明在晚冰川期（约16–12 ka BP），曼尼奇山谷的草原和半沙漠广泛分布。

Palaeoenvironments of the Manych Valley at the End of Late Pleistocene Based on Rodent and Mollusk Data from Sanmanych (Rostov District, Russia)

Abstract A thorough consideration is given to the geological, palaeotheriological and malacological materials obtained from the Pleistocene Sanmanych locality, which is the only locality with mammal fauna in the Manych depression (46°24′53″ N, 42°36′25″ E). The brackish-water mollusk composition indicated that the bone-bearing series should be correlated to the Early Khvalynian transgression. The fossil record gives an insight into the palaeoenvironment at the time that the Caspian Sea water broke through the Manych depression into the Black Sea basin. The faunal evidence points to arid conditions and a cool climate. The rodent species composition is rather poor; it exclusively includes species indicative for an open environment, which suggests a wide spread occurrence of steppe and semi-deserts in the Manych valley during the Late Glacial (~16–12 ka BP).

期刊介绍： Fossil Imprint (formerly Acta Musei Nationalis Pragae, Series B – Historia Naturalis) is an international, open access journal, publishing original papers and reviews of any length from all areas of paleontology and related disciplines, such as palaeoanthropology, biostratigraphy, palynology, and archaeobotany/zoology. All taxonomic groups are treated, including plants, invertebrates, vertebrates, microfossils, and ichnofossils, with a special emphasis on terrestrial and post-Palaeozoic marine biota. We encourage the publication of international meetings as well as special thematic issues. The aim of the journal is to spread the scientific knowledge with no restrictions, and to allow access to it to any interested person. Each article includes information about the date of receiving, accepting and issue.
