Получены первые данные датирования органогенных отложений разреза на р. Большая Дубёнка. Предварительная оценка изохронного 230Th/U возраста серии образцов из торфа и нижней части песчанистой гиттии позволяет предположить, что начало термического максимума последнего межледниковья, определенного с помощью спорово-пыльцевого анализа, в разрезе на р....
In this article, we highlight the characteristic features of the Late Rupelian Buran flora of Eastern Kazakhstan. The species list contains 65 plant taxa belonging to Polypodiophyta (2), Gymnospermae (12) and Magnoliopsida (51). Its composition is dominated by leaves, fruits and pollen of Carya; there are also in noticeable quantities of remains of...
Основная цель настоящего исследования состояла в получении точных количественных оценок возраста отдельных этапов микулинского межледниковья по данным 230Th/U датирования и палеоботанического изучения органогенных отложений известного опорного разреза “Нижняя Боярщина”. Выбор данного разреза связан с наличием достаточно мощной органосодержащей толщ...
До сих пор нет единого мнения о временных рамках и продолжительности микулинского межледниковья. Решение этого вопроса предполагает выполнение широких палеогеографических исследований большого числа разрезов микулинских отложений, в т.ч. на Северо-Западе Русской Равнины. В ходе полевых работ, проведённых в сентябре 2021 г., удалось найти несколько...
New data on fossil insects, soil and freshwater invertebrates, plant macrofossils, pollen and spores were obtained from a problematic lower unit of the reference section Bely Yar-II (Tunka Rift, Baikal Region, Russia). The invertebrates show a natural succession from a small lake to a wetland; plant macrofossils confirm the early stages of successi...

Additional material for the article "Rupelian Kazakhstan floras in the context of Early Oligocene climate and vegetation of Central Asia"
The Oligocene represents a transitional phase from a “hot‐house” to a “cold‐house” climate. Central Asia has undergone substantial environmental changes and tectonic events; however, we know little about how these tectonic events shaped the climate and biodiversity in Central Asia. Here, we present a detailed study on the early Oligocene paleobotan...
Spatial vegetation patterns potentially reflect coeval continental climate variations which are also impacted by palaeogeographical settings. Plant functional types (PFTs) and their distribution, frequently applied in ecological studies and biome modelling, serve as a tool for reconstructing palaeovegetation units and ultimately tracing palaeoecolo...
The investigation of the fossil floras from the Turgai plateau (central Kazakhstan) contributes to a better understanding of the origin of the temperate Turgai type flora which spread to Kazakhstan and adjacent areas during the Oligocene–Miocene transition. In this paper, we present the results of a carpological and palynological study of the Kumyr...
Based on ecospectra of 66 published carpofloras we study dynamics and evolution of Turgay vegetation in Western Siberia during the early Oligocene to earliest Miocene. The ecospectra are obtained using a Plant Functional Type (PFT) classification system comprising 26 herbaceous to arboreal PFTs. The carpofloras originate from seven floristic levels...
The evolution of plant ecosystems during the Cenophytic was complex and influenced by both abiotic and biotic factors. Among abiotic forces were tectonics, the distribution of continents and seas, climate, and fires; of biotic factors were herbivores, pests, and intra- and interspecific competition. The genus QuercusL. (Quercoideae, Fagaceae) evolv...
Despite the existence of a rich record, fossils of Carex have been largely neglected by neobotanists. Here we present an exhaustive critically commented checklist of the so-far published pre-Pleistocene records ascribed to Carex. We have made every attempt to include all pertinent paleobotanical literature. The extensive collection of the Museum fü...
Premise of research. The Cenozoic fossil record is crucial for understanding the evolution of the remarkably high diversity of angiosperms. However, the quality and biases of the angiosperm fossil record remain unclear mainly due to the lack of a global database.
Methodology. We introduce a new global occurrence-based database for Cenozoic angiospe...
Nelumbo Adans. (Nelumbonaceae) is an important member of the early-diverging eudicots. It contains two extant species: N. nucifera Gaertn. (the Sacred lotus), distributed in Asia and Australia and N. lutea Willd. (the American lotus), occurring in North America. This paper reviews the taxonomic, evolutionary and phytogeographic studies of the genus...
The historical reconstruction of the origin and dispersal of plant taxa in space and time facilitates a better understanding of their modern distribution patterns. However, most studies of paleobiogeography have focused on terrestrial plants, and the distribution changes of aquatic plants are less well understood. Here we study the lotus plant Nelu...
Cenozoic vegetation change in Western Siberia and northeastern Russia is
quantified based on the analysis of diversity of plant functional types
(PFTs). Carpofloras (148 total) compiled from published sources are
assigned to a total of nine time slices spanning the period from the middle
Eocene to the late Pliocene. Comparisons among four defined k...

Th e Cenozoic continental deposits of Western Siberia, Eastern Siberia and the Russian Far East are best
described on the basis of carpological records. Th e palaeoclimate evolution has been reconstructed quantitatively
(Coexistence Approach) providing inferred data on temperature, precipitation and the mean annual range of these
parameters. Climat...
Recent studies in the frame of the NECLIME (Neogene Climate Evolution in Eurasia) network provide a comprehensive inventory of continental palaeoclimate data for various time slices reconstructed from the palaeobotanical record. The integrative analysis of spatial gradients and patterns observed from the proxy data, together with data obtained from...
Elucidating the spatio-temporal distributions of terrestrial plants is a key for interpreting the origin of distribution patterns and the tempo of intercontinental disjunction. Nordenskioeldia was distributed in eastern Asia and North America from the Late Cretaceous to the Miocene. Its fossil record provides important information on former pattern...
