| Abstract: | The leaflet architecture of Cyclocarya cf. paliurus (Batal.) Iljinskaja from the Hunchun Formation (Middle Eocene) shows similarity to that of modern C. paliurus (Batal.) Iljinskaja and the specimen is the oldest fossil record in Europe and Asia. The distributions of C. cf. paliurus and other fossil records,such as Glyptostrobus, Metasequoia, Nyssa, and Liquidambar, in Hunchun flora show that it would have been a warmer-temperature to subtropical climate in Hunchun District during the Eocene period. |
