| 摘 要： | 报道产于福建西部三叠—侏罗纪界线附近的一个生物群，包括介形类Tungchuania sp.,Gomphocythere?yuba-cunensis,Gomphocythere? longa等，双壳类Shaanxiconcha spp.和植物，此生物群属于华北生物区系。讨论了毕业生物区生物在华南出现的意义，认为标志着当时华北与华南两大陆块已经拼合。

| Abstract: | A faunal assemblage from the lacustrine deposits of the Triassic-Jurassic houndary beds in western Fujian, southChina, is reported which are composed of ostracods Tungchuania sp., Gomphocythere? yubacunensis, Gomphocythere? longaetc. and bivalves Shaanxiconcha spp. The assemblage has been identified as belonging to the North China bio-province, andhence it most probably was migrated from the North China continental block at that time. This, however, significantly indicatesa faunal dispersion and migration between bio-provinces happened after a collision between the North China and South Chinacontinental blocks. |
