疑源类
ARENIGIAN ACRITARCHS FROM THE CHAOCHIAPA FORMATION OF? NINGQIANG COUNTY, SHAANXI PROVINCE?? 陕西宁强赵家坝组阿伦尼克期疑源类
Recorded herein are 197 species of 90 genera of spores and pollen and 4 species of 2 genera of fossil algae and 2 species of 2 genera of acritarchs. 建立三叠纪的孢粉组合序列（5个组合、2个亚组合），并详细地讨论各个组合的地质时代。
The acritarch assemblage available can be used fur biostratigraphic correlation of the Qingbaikou System in the vast Yanshan region, North China. 以上疑源类的稳定性和可比性，可作为具有广泛生物地层对比依据。
A moderately abundant and diverse acritarch assemblage was recovered from the Miaopo Formation at 4 sections in Yichang area, Hubei, South China. 湖北宜昌地区庙坡组是达瑞威尔阶/桑比阶界线附近的地层,该段地层产出分异度较高,丰度适中的疑源类组合。
