Short summary
Short summary
An integrated litho-, bio-, cyclo-, and magnetostratigraphy constrains the onset of a depositional environmental change from a lacustrine to a deltaic environment in the Maoming Basin, China, at 33.88 Ma. This coincides with the global cooling during the Eocene-Oligocene transition (EOT) at ~ 33.7–33.9 Ma. This change represents terrestrial responses of low-latitude Asia to the EOT. The greatly refined chronology permits detailed examination of the late Paleogene climate change in southeast Asia.

Short summary
We reconstruct late middle Eocene (42.0–38.5 Ma) pCO2 based on the fossil leaves of Nageia maomingensis Jin et Liu collected from the Maoming Basin, Guangdong Province, China. This work indicates that the stomatal density (SD) inversely responds to pCO2, while stomatal index (SI) has almost no relationship with pCO2, using "modern" leaves of N. motleyi (Parl.) De Laub. Regression approach gives a pCO2 of 351.9 ± 6.6 ppmv, whereas stomatal ratio method gives a pCO2 of 537.5 ± 56.5 ppmv.
