摘要(Abstract)：

东方叶肢介Eosestheria在松辽盆地首次发现,这是叶肢介化石研究中的一项重大进展。为热河生物群的分布、发展、沉积环境研究增加了新的内容,为地层划分对比提供了重要依据,对松辽盆地深层勘探寻找新的油气资源提供了信息。由于岩性较粗,标本保存欠佳,经研究共有4种。化石层上下为火山岩所夹,化石产出情况及生物群面貌大致与辽西、冀北上侏罗统义县组相似。
The first discovery of Eosestheria in Songliao Basin is a great advance in the study of conchostraca. It has enriched our knowledge in the study of the distribu tion, development, evolution and sedimentary environment of Rehe biota, provid ing an important basis for stratigraphical division and correlation, as well as the information needed for the searching of deep reservoirs for new oil and gas re sources. Four kinds of Eosestheria have been found since the lithology is compara tively coarse and the samples are not well preserved. The fossil bed is interbeded by volcanic rocks, and the occurrence of the fossil and the appearance of biota are similar to that in the Yi Xian Formation of upper Jurassic in west Liaoning and north Hebei.
