铜川阶

是中国陆相中三叠统上部的一个阶,位于二马营阶之上,上三叠统下部胡家村阶之下。阶名源自岩石地层单位“铜川组”,层型剖面位于陕西铜川金锁关。铜川阶的底界生物识别标志尚待深入研究后定义。阶内含丰富的各门类化石,古植物主要有:Equisetites brevidentatus,E. sthenodon,Neocalamites carcinoides,Danaeopsis magnifolia,D. plana,Pleuromeia labiata,P. tongchuanensis,Tongchuanophyllum concinnum,T. trigonum,T. shensiense,Glossopteris chinensis等;介形虫主要有:Tungchuania houae,Darwinula accuminata,D. schneideri等;双壳类主要有:Shaanxiconcha longa,S. elongata,S. fragilis,S. subovata,Unio huangbogouensis等;叶肢介有:Euestheria tongchuanensis,E. gibba,E. celeta,E. jinsouguanensis等;孢粉为PunctatisporitesGranulatisporitesChordasporites组合;还有昆虫类:Triassoblata phyllopteris,Minonymthites orthophlebes,Rhpidoblata lonchopteris等。
