| 摘 要： | 我国北方18-19亿年前的串岭沟组中获得的大球形疑源类，迄今，被认为是可信的最古老真核化石记录。自上世纪80年代以来，东秦岭北坡的中元古代晚期汝阳群陆续发现了丰富的球形光面疑源类，具刺疑源类，丝状微体化石和一些有疑问的动物遗迹。很显然，在中元古代晚期真核生物曾有重大辐射。

| Abstract: | Until now, the convincingly oldest fossil record of eukaryotes is of large sphaeromorphic acitarchs from the Chuanlinggou Formation (1800-1900Ma), China. In the last two decades, abundant sphaeromorphic acritarchs, acanthomorphic acritarchs, filamentous microfossils and some doubtful animal traces have been found from late Mesoproterozoic Ruyang Group in north slope of eastern Qinling Mountains, China. It is obvious that eukaryotic organisms experinced a significant radiation during the late Mesoproterozoic. |
