| 摘 要： | 在宁夏贺兰山蓟县系王全口群顶部和青海柴达木盆地北缘蓟县系全吉群红藻山组叠层石Colonnella和Conophyton的柱体之间充填物中,发现的大量管状化石,实为一种微小生物潜穴,说明后生动物的起源和早期演化提供了实际材料;同时它们可能具有区域地层划分对比的潜力,值得引起注意。

| Abstract: | In the upper part of Wangquankou Group. Jixian System, Helan Mountain, Ningxia and the Hongzaoshan Formation, Quanji Group, the Northern Margin of Qaidam Basin, Qinghai Province, a lot of tubular fossils were discoved in the filling materials be- tween stromatolite columns. They are consideted as burrows of some kind of small drilling-organisms. According, metazoa are supposed to appear before 1000Ma. This is of great importance to the study on the origin and early stage evolution of metazoan, and may offer potential help to regional strata division and correlation. This discovery is worth of much attention. |
