Article
Full-text available
Spinescence is an important functional trait possessed by many plant species for physical defence against mammalian herbivores. The development of spinescence must have been closely associated with both biotic and abiotic factors in the geological past, but knowledge of spinescence evolution suffers from a dearth of fossil records, with most studie...
Article
The antiquity of the tropical Asian flora is being revealed by recent detailed work on a number of Cenozoic plant megafossil sites, some of which have been radiometrically dated for the first time, but our knowledge of how the highly diverse modern biota came into being remains poor due to a sparsity of records. In this paper, we describe fossil pl...

Extant Bauhinia (Leguminosae) is a genus of 300 species of trees, shrubs, and lianas, widely distributed in pantropical areas, but its diversification history in southeastern Asia, one of its centers of highest diversity, remains unclear. We report new fossils of three Bauhinia species with cuticular preservation from the Paleogene of Puyang Basin,...
Article
Recent paleobotanical investigations in Vietnam provide a good opportunity to improve our understanding of the biodiversity and paleoclimatic conditions in the geological past of Southeast Asia. Palms (Arecaceae) are a diverse family of typical thermophilous plants with a relatively low tolerance for freezing. In this study, we describe well-preser...
Article
Trapa (water chestnut or water caltrop) is a genus of annual free-floating plants mostly native to Africa and Eurasia and included in the family Lythraceae. The genus only contains 10 species today but has a large number of species in the Neogene record, mainly based on fruits but also on the occurrence of pollen grains. In China, several species h...

Early Palaeolithic wooden implements are exceptionally rare. The best known are the spears and throwing sticks from Schöningen, Germany dated to ca. 300–330 thousand years (kyr) ago 1,2 and the 171-kyr old digging sticks from Poggetti Vecchi, Italy ³ . Here, we report a unique assemblage of 35 wooden implements from the site of Gantangqing, southwe...
Article
Full-text available
The West Kunlun region forms the northern margin of the Tibetan Plateau, and sedimentation in this region contributed to plateau formation and its northwards expansion, as well as the development of central Asian aridification. However, the stratigraphic dating framework in this region has been ambiguous, hampering the understanding of both tectoni...
Article
Full-text available
The growth of the Tibetan Plateau throughout the past 66 million years has profoundly affected the Asian climate, but how this unparalleled orogenesis might have driven vegetation and plant diversity changes in eastern Asia is poorly understood. We approach this question by integrating modeling results and fossil data. We show that growth of north...
Article
Full-text available
Tibet’s ancient topography and its role in climatic and biotic evo- lution remain speculative due to a paucity of quantitative surface- height measurements through time and space, and sparse fossil records. However, newly discovered fossils from a present eleva- tion of ∼4,850 m in central Tibet improve substantially our knowl- edge of the ancient...
Article
Illigera (Hernandiaceae) is a liana genus distributed mainly in the tropical Asia and Africa. Previous fossil records suggested that Illigera was restricted in western North America during the Eocene. Recent paleobotanical investigation has unveiled a Paleogene flora that is totally different from today's vegetation in central Tibet. This provides...
Article
Herbivore damage patterns on fossil leaves are essential to explore the evolution of plant-herbivore interactions under paleoenvironmental changes and to better understand the evolutionary history of terrestrial ecosystems. The Eocene–Oligocene transition (EOT) is a period of dramatic paleoclimate changes that significantly impacted global ecosyste...
Article
The early Oligocene represents the beginning of the modern icehouse world. To better understand how vegetation and climate changed during this period, we reconstruct quantitively the early Oligocene vegetation and climate by analyzing fossil spore and pollen assemblages from Lühe basin, Yunnan Province, in southwestern China. The reconstructed pale...

Plain Language Summary The deposition of eolian loess in the Chinese Loess Plateau provides critical information for understanding the aridification history of the Asian interior and the uplift of the Tibetan Plateau. However, eolian deposits in the Lanzhou Basin of the western Chinese Loess Plateau dated to the interval of 3.6–2.2 Ma have rarely b...
Article
A series of erosional surfaces, including a planation surface (PS) and several fluvial terraces are well preserved in the Dabanshan Mountains, northeastern (NE) Tibetan Plateau. The Dabanshan planation surface has been divided into several platform patches by river incision, including the Dongping PS and the Halagu PS, and is overlain by Late Cenoz...
Article
Premise: Apocynaceae is common in the fossil record, especially as seed remains from the Neogene of Europe and North America, but rare in Asia. Intrafamilial assignment is difficult due to the lack of diagnostic characters, and new fossil and modern data are needed to understand the paleobiogeography of this group. Methods: We studied three Apoc...
Article
Three fossil species of Equisetum (Equisetaceae) were reported from the Neogene of south-western China and northern Vietnam, based on well-preserved rhizomes with tubers. Equisetum cf. pratense Ehrhart from the middle Miocene of Zhenyuan County, Yunnan Province, China is characterised by a bunch of three ovate tubers with longitudinal ridges on the...
Article
A new occurrence of buckthorn fossil leaves is reported from the upper Eocene strata of Markam Basin, southeastern Tibet, China. The leaf margin is either entire or slightly sinuous. Secondary veins are regularly spaced, forming eucamptodromous venation. These secondaries exist as straight lines from midvein to near margin and then arch abruptly up...
Article
The biodiversity history on the Qinghai‐Tibetan Plateau (QTP) has remained unclear for a long time. Recent palaeobotanical investigations provide opportunities for revealing the phytogeographic history on the QTP in deep time and for testing phylogeographic hypotheses. Lagokarpos is an extinct genus with unknown modern affinities. It is easily dist...
Article
A substantial biotic interchange took place between Gondwanan India and Laurasia immediately following the India-Eurasia collision. Located just north of the collision zone, the role of the Tibetan Plateau in the geographic interchange of biota is still unknown because lack of fossil evidence. Here, well-preserved samara fossils of Ailanthus (the f...

The uplift history of southeastern Tibet is crucial to understanding processes driving the tectonic evolution of the Tibetan Plateau and surrounding areas. Underpinning existing palaeoaltimetric studies has been regional mapping based in large part on biostratigraphy that assumes a Neogene modernisation of the highly diverse, but threatened, Asian...

As a remnant elevated peneplain, the Tangxian planation surface is widely distributed in North China and the Ordos Plateau. Further into the Tibetan Plateau (TP), the Main planation surface can also be traced across this, the highest plateau on the Earth's surface. What the relation is between these two planation surfaces and whether they represent...

Holding a climatically and geologically key position both regionally and globally, the northeastern Tibetan Plateau provides a natural laboratory for illustrating the interactions between tectonic activity and the evolution of the Asian interior aridification. Determining when and how the late Miocene climate evolved on the northeastern Tibetan Pla...
Article
The long-term paleoclimate record in Asia and its comparison with the global climate record are of vital importance to understanding the coupling mechanisms between tectonics and climate. However, such long-term climate history in Asia revealed using the biomarker perspective has remained elusive. Here, we reconstruct the Neogene–Quaternary climati...

Project
The Jianglang locality (Bangor County, Tibetan Plateau, China) is situated at an altitude of 4850 m along the Bangong-Nujiang Suture. The Cenozoic sediments belong to the Niubao Formation in the lower part and the Dingqing Formation in the upper part. The fossil site has 5 distinct sections, and we find in total ca. 1500 fruits, seeds, leaves, tubers and stems. Among them, ca. 150 fossils correspond to ca. 34 morphotypes of fruits and seeds. The aim of this project is to study in detail the fruit and seed biodiversity of the Jianglang site, to reconstruct the paleoenvironment and to improve the understanding of the biogeographic role of the Tibetan region during the Eocene.
