| 1 | 中国陆相白垩纪-古近纪(K/Pg)界线研究综述显示文摘白垩纪-古近纪(K/Pg)界线地层蕴含了全球性的地质事件信息,特别是显生宙第5次生物大灭绝事件(如恐龙的灭绝),该界线的研究一直是学术界的热点。目前国内约30个地区发现了陆相K/Pg界线,主要分布在中国东部地区,证据包括恐龙蛋铱含量及碳氧同位素,恐龙牙齿及蛋化石、微球粒、黏土矿物、介形类动物群、轮藻、孢粉和环境磁学变化,多为古生物方面的研究,这些证据所反映出的气候信息相似,地球化学元素异常呈现出等时性和普遍性。中国陆相K/Pg界线与国外海相K/Pg界线相对比,由于陆相地层的缺失、生物演化关系及保存条件的制约,其研究难度大、程度低、进展缓慢,中国发现的大部分K/Pg界线点论据不甚充足,有2个或2个以上证据链的界线点只有9个。 | 江瑶 刘雪敏 时志强 李建亭 王燕燕 | 2021 | 桂林理工大学学报2021，41，3： | 6 |
| 2 | A potential stratotype for the regional lowermost stage of the continental Paleocene in China显示文摘Phanerozoic chronostratigraphic units can only be defined through their lower boundary stratotypes.The lowermost stage of the Paleocene of China,which mainly consists of terrestrial deposits,can only be defined through its lower boundary stratotype,i.e.the continental Cretaceous/Paleogene boundary stratotype.There is no section yet found which contains continuous terrestrial deposits and biostratigraphic records of the Cretaceous-Paleogene transition in Nanxiong,Guangdong and Jiayin,Heilongjiang,there is no evidence for establishing the continental stratotype of the Cretaceous/Paleogene boundary in either area.Therefore,both the'Shanghuan stage'and'Furaoan stage'are not good candidates for the lowermost stage of the Paleocene of China.From the viewpoint of charophytes,the outcrop section of the Dangyang,Hubei Province(Central China)contains the most continuous,abundant and diverse terrestrial biostratigraphic records of the Cretaceous-Paleogene transition,in particular the early Paleocene,known so far in the world.The biostratigraphic records of ostracods in the transition are also continuous,rich,and diverse.The Dangyang outcrop section is the only section known so far in China that is a possible candidate for a continental stratotype of the Cretaceous/Paleogene boundary in China and the section is the only potential section identified to date for establishing the regional lowermost stage of the Paleocene,Paleogene and Cenozoic in China or stratotype section for the stage. | LI WeiTong LIU GengWu Dennis R.BRAMAN LI YiBin CAO WeiSheng Don BRINKMAN SHEN Jiao CHEN QingBao | 2014 | Science China Earth Sciences2014，57，5： | 3 |
| 3 | A new alvarezsaurid dinosaur from the Late cretaceous Qiupa Formation of Luanchuan,Henan Province,central China显示文摘An alvarezsaurid dinosaur skeleton was discovered from the Late Cretaceous Qiupa Formation of Luanchuan,Henan Province of eenttral China.It represents a new alvarezsaurid dinosaur Qiupanykus zhangi gen.et sp.nov.A phylogenetic analysis recovers Qiupanykus nested within the unresolved clade,which includes Asian and north American taxa.The skeleton of the new specimen is preserved in association with eggshells.The eggshell morphologies show that these eggs belong to oviraptorid eggs,skeletal remains of which were discovered from the same area.The alvarezsaurid skeleton associated with eggshell fragments may indicate that these eggs were broken by the strong thumb-claws of the former and that alvarezsaurid dinosaurs may be egg-eaters. | Jun-chang Lu Li Xu Hua-li Chang Song-hai Jia Ji-ming Zhang Dian-song Gao Yi-yang Zhang Cheng-jun Zhang Fang Ding | 2018 | China Geology2018，1，1： | 1 |
