Abstract—

Species of the genus Anmarginulina were widespread in the Arctic basins during the Late Pliensbachian. This group is important for biostratigraphy, global correlation, and paleobiogeography. The comprehensive study of Late Pliensbachian species of the genus Anmarginulina from the sections of the Arctic Siberia has been carried out for the first time.

摘要-

晚期Pliensbachian时期，北极盆地中普遍存在Anmarginulina属。该组对于生物地层学，全球相关性和古生物地理学很重要。首次对北极西伯利亚地区的Anmarginulina属晚期Pliensbachian物种进行了综合研究。
