摘　　要：黑龙江省桦南县道台桥组植物孢粉化石初步报道刘耕武，李浩敏，冷琴（中国科学院南京地质古生物研究所，南京２１０００８）关键词植物孢粉化石，道台桥组，黑龙江１９９４年６月至８月，笔者赴黑龙江禅南县八虎力乡四方台村进行了野外考察及化石采集工作，发现了大量植物...A Mlocene flora has beendlscovered from the Daotalqlao Formation of HuananCoun ty,Hellongjlang Province ofNEChlna.The fossil site Is located at about 47“ N.Lat.and 130” E.long., with both megafosslls and mlcrofosslls of plants well preserved. The megafosslls comprise at least 14 families,20 genera and more than 30 spedes,with such largest families as Betulaceae(Including Betula, Alnus’uns’trya)and Fagaceae(IncludingQuercus, Fagus, stanea) and other important families as Sallcaceae, Aceraceae,Rosaceae, Cercldlphyllaceae, Alanglaceae, Oleaceae, Hamamelldaceae, Saxlfragaceae, Anacardlaceae, Ulmaceae, Plnaceae and Osmundaceae.The mlcrofosslls contain at least 12 famllies’25 genera and more than 30 types, forming a pollen flora domlnatedby Betulaceae (Betula, Alnus,Carplnus,Ostrya)and FagaCeae(Quercus,Fagus),together With abUndant Juglandaceae(Pterocarya,hrya and Juglans),Plnaceae(Plnus,Plcea,Tsu,Larsx,Ables),Ulmaceae(Ulmus and Zelkova/Ulmus)and some other families Including Sallcaceae,Aceraceae, Rosaceae Nyssaceae Oleaceae and Cupressaceae.There are less abundant pterldophyte spores, mostly of Polypodlaceae and Lycopodlaceae.The present flora Is assigned tolate middle Mlocene to late Mlocene, In geologlcal age which Is close to that deduced fromthe fossil vertebrates(flshand elephants)ofthls formation.Bothmegafosslls and mlcrofosslls of the flora reflect a deciduous broad.leaved forest or a mlxed conifer and deciduousbroad-leaved forest under a warm temperate climate.
