摘要	Equisetum fossils are often reported from the Cenozoic strata in the Northern Hemisphere, but their occurrence in the QinghaiTibetan Plateau (QTP) region is scarce. In this investigation, two new species of tuber fossils of Equisetum - Equisetum wulanense Zhang and Xie, n. sp. and Equisetum kekeense Zhang and Xie, n. sp. from the Miocene Youshashan Formation of the Wulan Basin, Qinghai Province are reported. The extant Equisetum plants are usually living in wet habitats. Therefore, fossil species, E. wulanense and E. kekeense, were likely to live in moist environments during Miocene too. The discovery of E. wulanense and E. kekeense in the late Middle Miocene (-13.4 Ma) indicates that the local climate of the Wulan Basin was more favorable during this period. This new finding confirmed the previous view that the Neogene aridification in the northern QTP was varying: the climate in the Early Miocene and the Middle Miocene were relatively warm and humid and then the climate gradually became colder and drier since the Late Miocene. It is widely accepted that the uplift of the QTP intensified the trend of cooling and drying since the Late Miocene, and eventually formed a cold and dry climate pattern in the northeast margin of the QTP. The discovery of Equisetum fossils in this investigation improved our understanding on the Cenozoic diversity of Equisetum plants in the northern QTP, as well as on the paleoecological environments of the Wulan Basin in Miocene.
