摘要
本文描述的具角质层的两块叶化石,产自广西百色盆地更新统长蛇岭组。经与现代植物的角质层对比研究后,确定这两块叶化石分属于樟科的两属两种,即油丹(近似种)(Alseoda-phne cf.hainanensis Merr.)和紫楠(近似种)[Phoebe cf.sheareri(Hemsl.)Gamble]。研究结果表明,角质层在鉴定被子植物化石中具有可靠的价值。
Two fossil leaves with cuticle described here were collected from tile Pleistocene Changsel- ing Formation of Baise Basin,Guangxi.A detailed comparison of the cuticular analysis between the fossils and their living equivalents indicated that the two fossil species belong to 2 genera of Lauraceae,that is,Alseodaphne cf,hainanensis Merr.and Pheobe cf.sheareri (Hemsl.) Gamble. The first report on lauraceous fossil leaves with cuticle in China showed that cuticular analysis had a reliable value in identifying the angiospermous fossil plants.
