The reconstruction of the climate in the Miocene Shanwang basin is an important link in understanding past climate and environmental changes in East Asia. A recent study showed that the mean annual temperature (MAT) estimates derived from leaf margin analysis (LMA) and the Climate Leaf Analysis Multivariate Program (CLAMP) conflicted with and were...

The record of fossil plants in China can date back to the year 1086 during the Chinese Song Dynasty. The subject of palaeobotany was transplanted into China in the early 20th century. The rise of Chinese palaeobotany had direct connections with the world. V.K. Ting played a major role in the establishment of academic organizations and English journ...

The Miocene Shanwang biota from eastern China contains exceptionally well-preserved plant fossils with abundant leaf fossils and palynomorphs co-occurring at several levels in the sedimentary succession. This has provided an ideal opportunity to undertake detailed comparative quantitative palaeoclimate reconstruction, based on both mega- and microf...

The living trees of Eucommia ulmoides, an endemic species in China, grow from 200 to 1700 m above sea level, within the geographic range from 102° E to 118° E and from 25° N to 35° N. Spring temperatures in these regions vary from 12.3°C to 20.1°C. A physiological study (using germination tests) of E. ulmoides has been undertaken to test the role o...

The fossil leaf flora from the Shanwang Formation, Linqu County, Shandong Province, eastern China, is diverse, abundant, well preserved and discretely spaced, all of which make it suitable for the recognition and application of leaf physiognomic characters. This article is the first study of Chinese Tertiary floras using the CLAMP (Climate Leaf Ana...

There are many extant endemic plants in China, which were widely distributed in the North Hemisphere during the Tertiary. The global cooling during the Tertiary caused a series of narrow distribution regions of the plants. Quartemary glaciation invaded most regions of North America and Eurasia where severe destruction was imposed onto vegetation. H...

... Warm and humid climates are more favorable for the growth of Choerospondias [85]. Based on the living environments of extant Choerospondias, semiquantitative climatic parameters in the late Miocene eastern Zhejiang were obtained using the method of climate analysis of endemic species (CAES) [86,87] Many plant fossils from the Shengxian Formation in eastern Zhejiang have been identified, and their modern equivalents are mostly distributed in tropical or subtropical humid zones [24,25,88]. The MAT and MAP values in late Miocene eastern Zhejiang have been quantitatively reconstructed based on these plant fossils in previous studies (Table 3). ...
... The coexisting approach (CoA) has been used for quantitative Cenozoic terrestrial paleoenvironmental and paleoelevation reconstructions (Mosbrugger and Utescher, 1997;Yang et al., 2002;Mosbrugger et al., 2005;Sun et al., 2014;Utescher et al., 2014;Wu et al., 2018), with the aim to acquire the coexistence interval of ranges in paleotemperature and paleoelevation derived from the nearest living relatives (NLRs) of fossil pollen taxa. Accordingly, the results of CoA are essentially controlled by the precision of NLR identifications and their altitudinal information. ...
... In an admittedly brief assessment that mentioned the relative youth of palynology and its existence and prospects for China, Jen Hs€ u (1956) does not mention Su Ting. A review of the 'Rise of Chinese palaeobotany' (Sun 2005) mentions Jen Hs€ u but not Su Ting. The most recent comprehensive evaluation of Quaternary pollen and spores for the country (Tang et al. 2019) does not cite anything earlier than 1959 (Qin 1959; this is a monograph that is not about the Quaternary as such, but rather about early work on pteridology systematics in China). ...
... Although the process of forest development in southern China after the arid belt disappeared is still unclear, recent plant fossil evidence shows that typical evergreen broad-leaved forests existed during the Miocene across northern Jiangxi Province, southern China (Personal communication with Dr. Hai Zhu). The MMCO Shanwang flora from eastern China also has the characteristics of a transition from a subtropical to a temperate zone (Sun et al., 2002), the subtropical taxa still showing a strong relationship with the southeast Asian flora. The PGT, directly connected to subtropical China, provided a persistent source of numerous taxa. ...
... The CA, like CLAMP, relies only on the presence/absence of taxa and is independent of sample size and relative abundance. CA reconstructions have been validated by other independent methodologies such as CLAMP (Liang et al. 2003;Uhl et al. 2007;Xing et al. 2012;Bondarenko et al. 2013). Generally, the CA results are also supported by oxygen isotope data retrieved from marine archives and palaeovegetational reconstruction (Mosbrugger et al. 2005;Utescher et al. 2015;Srivastava et al. 2016Srivastava et al. , 2018. ...
... Provided that temperature preference of modern Eucommia ulmoides can be extrapolated to Eocene Eucommia species, the spring temperatures during deposition of the Landauer Mergel was from 13 °C to 20 °C (Yu-Fei Wang et al. 2003). The dinocyst Apectodinium is very abundant and reaches 99 % in one sample. ...
... The study of Late Miocene climate change is crucial to predict future climatic change and improve the living environment of human beings. Moreover, the morphology and distribution of plants are more sensitive to climate change and are ideal indicators for reconstructing paleoclimate [3]. The leaf characteristics of terrestrial plants have been shown to be influenced by climate change and are ideal indicators for studying climate change [4]. ...
