New Data of Phosphatized Acritarchs from the Ediacaran Doushantuo Formation at Weng'an, Guizhou Province, Southwest China
摘要
Abstract
Abundant phosphatized acritarchs are preserved in the late Precambrian (Ediacaran) Doushantuo Formation at Weng'an, Guizhou Province, southwest China. Most of them are large with various spinous ornaments and multilayered outer walls. The general characters of these fossils are quite similar to those found from the homochronous deposits of the Yangtze Gorges, southern China. Therefore the Doushantuo Formation in the Weng'an area can be correlated directly with the Doushantuo Formation of the Yangtze Gorges. Four species in four genera, including two new genera, two new species and one uncertain species are systematically described for the first time from the studied locality. The taxa are Bacatisphaera baokangensis Zhou, Brasier et Xue, 2001, Taeniosphaera doushantuoensis gen. et sp. nov.,Rugospinasphaera speciosa gen. et sp. nov. and Meghystichosphaeridium sp. The new data enriches the famous Weng'an biota, especially the marine microplankton flora in the Ediacaran Doushantuo Formation.关键词
