Extended Data Fig. 8: Timing of Xining CIE compared with CENOGRID and astronomical solutions.

From: Proto-monsoon rainfall and greening in Central Asia due to extreme early Eocene warmth

Extended Data Fig. 8

CENOGRID showing the evolution of benthic foraminifera stable isotope values4. The δ18O values show peak warmth of the EECO and the δ13C values show several hyperthermal events characterized by negative CIE’s. The astronomical solutions76 show the evolution of the eccentricity of Earth’s orbit. The radiometric ages bracketing the CIE in the Xining Basin are indicated.
