In northeastern China, a relatively small number of localities have provided most of our data on Paleogene megafossil plants. In most cases, the stratigraphic ages have been estimated on the basis of floristic correlations; the precision of these age estimates is uncertain because there is lack of corroborative evidence from other methods. It is not surprising, therefore, that different authorities have proposed different ages for the these paleobotanical assemblages. A newly collected megafossil flora from an underground coal mine at Gonglantou, Huadian, Jilin Province, China (N42¡59Õ54Ó, E 126¡51Õ58Ó), occurs in association with a mammalian fauna indicating middle Eocene age. We report leaves of Ginkgo , Metasequoia , Platanus , Trochodendroides , Quercus , and several additional dicotyledonous leaf types as yet unidentified, along with fruits of Rhus , Koelreuteria , Craigia , and two genera of Menispermeae. The taxonomic composition of the flora is consistent with the interpretation of temperate to subtropical climate, and is similar to that of middle Eocene floras at comparable latitude in western North America.
