| 摘 要： | 重庆秀山地区下志留统龙马溪组上部的灰色页岩中产出有肉红色粉砂岩填充的U形浅潜穴双菌迹(Bifungites),其丰度较高,但属种十分单调,淡化潮坪相的沉积表明秀山地区早志留世龙马溪期晚期为淡化潮坪相的沉积.

| Abstract: | Most of trace fossils buried in suit could interpret the sedimentary environments and use in the paleogeography.A shallow U-shaped burrow filled with red siltston,Bifungites,was discovered in the gray shales of the Lower Silurian Longmaxi Formation at Xiushan,Chongqing.Abundant and monotonous Bifungites indicate that it was a desalted tidal-flat environment during the later Longmaxi period of the early Silurian in Xiushan area,Chongqing. |
