Plant fossils provide new insight into the uplift history of SE Tibet

Plenty of well-preserved plant fossils with well constrained geological ages were discovered from Markam Basin in SE Tibetan Plateau. Fossils from different layers are different in floristic components and leaf sizes, they evidenced the uplift to present elevation during the Eocene-Oligocene Transition (33.9 Ma). Moreover, these fossils suggest that the modernization of highly diverse Asian biota nowadays took place before the E-O transition, not Neogene as previous thought.
