The vegetation and climate during the L. keiyuanensis era. (a) Photomicrographs of selected single pollen grains. Blue scale = 20 μm; red scale = 5 μm; white scale = 1 μm. 1–3. Polypodiaceae; 4–6. Pinus; 7–9. Alnus; 10–12. Carya; 13–15. Castanopsis; 16–18. Fabaceae; 19–21. Typha; 22–24. Anacardiaceae. (b) Diagram showing changes in the relative abundances (expressed as %) of the major palynomorphs recovered from the Xiaolongtan section. (c) Coexisting intervals of palynological assemblages from the Xiaolongtan section. The upper boundary of climatic parameters is the red line segment, and the lower boundary is the blue line segment.

Cyperaceae; 14. Elaeagnaceae; 15. Ephedra; 16. Ericaceae; 17. Euphorbiaceae; 18. Fabaceae; 19. Juglans; 20. Lamiaceae; 21. Magnoliaceae; 22. Meliaceae; 23. Moraceae; 24. Oleaceae; 25. Pinus; 26. Poaceae; 27. Potamogetonaceae; 28. Quercus; 29. Ranunculaceae; 30. Rosaceae; 31. Rutaceae; 32. Sapindaceae; 33. Solanaceae; 34. Taxodiaceae; 35. Tilia; 36. Typha; 37. Ulmus. (d) Climatic parameters of individual horizons (Zones I-IV) from the Xiaolongtan section estimated by CoA. (e) The measured stratigraphic sequence of the Xiaolongtan Sect. [14] and the palaeotemperature, palaeoprecipitation, pollen concentration, plant diversity, and stable carbon isotopes.
