Although an abundance of 4-methyl-sterane and dinosterane thought to derive from dinoflagellates,has been detected in the Palaeogene source rocks and crude oils in the Qaidam Basin,china,no unequivocal dinoflagellate cysts have been found previously in Cretaceous-Palaeogene terrestrial deposits in this basin, including the Xiaganchaigou *** study reports on a new discovery using detailed analysis of a dinoflagellate cyst assemblage,composed solely of Subtilisphaera,from the Xiaganchaigou Formation on the north margin of the Qaidam *** biomarkers 4-methylsterane and dinosterane in the corresponding fossil-bearing beds have also been detected,further validating the dependability of dinoflagellate *** fossils provide direct evidence of the dinoflagellate contribution to Palaeogene crude oil in the Qaidam Basin and fill a long-existing gap in oil-source correlation.

Chinese Science Bulletin 2008年第24期53卷 3860-3865页

作者： CHEN Fang1,2 & DONG XiPing1,2 1 School of Earth and Space Sciences,Peking University,Beijing 100871,china 2 laboratory of Paleontology and stratigraphy,{3. institute of geology and Paleontology,Chinese Academy of Sciences,Nan-jing 210008,china School of Earth and Space Sciences Peking University Beijing 100871 China laboratory of Paleontology and stratigraphy Nanjing Institute of Geology and Paleontology Chinese Academy of Sciences Nanjing 210008 China

Countless fossil embryo Olivooides and the hatched larvae,juveniles and adults(the latter two kinds are Punctatus) are recovered by means of acid maceration from the fine-crystalline to medium-crystalline phosphatic limestone and phosphatic micrite of Early Cambrian Kuanchuanpu Formation at the Shizhonggou section,near Kuanchuanpu Village,Ningqiang County,Shaanxi Province,*** the technique of Synchrotron X-ray Tomographic Microscopy,the 3. internal structure of Olivooides and Punctatus is *** morphological and statistic analyses are also given to the stellae structure of Olivooides and Punctatus,which indicates that this structure is a result of adaptive evolution to a lifestyle of fast-attaching after hatching,probably with the function of mucilage *** internal structure of Punctatus is described and *** ovum-like structure,a common internal feature of Punctatus,is considered as the taphonomic structure,rather than eggs or other biological *** structure is thought to be formed after the burial of the animal and before or during the *** original internal structure of Punctatus is assumed to be tabulae-filled,with soft body grown on them.
