| 1 | 燕辽生物群和燕山运动显示文摘燕辽生物群和热河生物群是以我国燕辽地区为核心的两个中生代中晚期特异埋藏生物群,关系到哺乳动物的早期演化,最早的带毛恐龙,鸟类起源,被子植物起源,寄生昆虫等重大科学问题,引起科学界广泛关注。这两个生物群时代相差较远,代表分子差异很大。目前,研究者对燕辽生物群地层划分意见分歧很大,主要争论为内蒙宁城道虎沟化石层和辽宁建昌玲珑塔化石层的关系,将二者分别归入中侏罗统海房沟/九龙山组和中晚侏罗统髫髻山组,或均归入髫髻山组,这一分歧造成地层划分对比和生物演化序列的极大混乱,从未得到有效解决。本文结合近年来本地区同位素年代学、岩石地层学和生物地层学新进展,对上述地层划分提出新建议。结合前辈地质学家的基本思想对燕山运动的构造幕进行新的理解,并划分为序幕(即绪动期)约为168 Ma,第一幕(即火山幕)约为163.5 Ma,第二幕(即主动幕)约为135 Ma。其中序幕对燕辽生物群的形成至关重要,而第一幕导致其发生重大转变。道虎沟化石层的底砾岩角度不整合于前寒武系变质岩之上,这个界面代表燕山运动的绪动,在燕辽地区表现为砾石沉积,地壳垂直升降与小规模火山喷发,形成了一系列山间盆地,伴生了燕辽生物群的早期组合,如道虎沟生物群,以燕辽划蝽-'滦平真叶肢介'-费尔干蚌-初螈为代表,为中侏罗世中晚期。道虎沟化石层顶部的凝灰岩受到显著剥蚀,呈明显的角度不整合下伏于一套角砾岩之下,此不整合面代表燕山运动第一幕,造成一系列深度的北东向断裂,引发大规模岩浆侵入及髫髻山期火山喷发。燕辽生物群的早期群落随之瓦解并迅速扩散演化,且在燕辽地区发展形成燕辽生物群晚期组合,如玲珑塔生物群,以柴达木叶肢介-额尔古纳蚌-古鳕为代表,为晚侏罗世早期,与道虎沟生物群明显不同但存在广泛联系。京西九龙山-髫髻山组之下的不整合面和辽西海房沟组之下的不整合面不能对比,且髫髻山期大规模火山活动前存在两个重要的燕山期构造运动。过去的观点认为道虎沟化石层相当于九龙山组或在九龙山组之上,本文根据京西九龙山组是燕山运动第一幕之后的产物,而以道虎沟化石层为代表的海房沟组在其之前的基本观点,认为二者不能对比且是上下关系。燕山运动的第二幕发生于土城子组和张家口-大北沟组或义县组之间,从而造就了著名的热河生物群,它与燕辽生物群的过渡存在于土城子组。 | 黄迪颖 | 2015 | 古生物学报2015，54，4： | 34 |
| 2 | A New Species of Liadotaulius(Insecta:Trichoptera) from the Middle Jurassic of Daohugou,Inner Mongolia显示文摘Diverse caddis flies are recently collected from the Middle Jurassic Daohugou fauna in Ningcheng County,Inner Mongolia,northern China,and different types of caddis cases have been reported in the same locality.A new species of caddisfly,Liadotaulius daohugouensis sp.nov.is described and illustrated;the establishment is based on a well-preserved isolated forewing collected from the Middle Jurassic Jiulongshan Formation of Daohugou.The family status of Liadotaulius is discussed on the basis of new material and is referred to the family Philopotamidae.The Daohugou fauna continues to provide new data for studying the early evolution of Trichoptera. | WU Hao HUANG Diying | 2012 | Acta Geologica Sinica(English Edition)2012，86，2： | 4 |
| 3 | The Earliest Ascidiate Carpel and Its Implications for Angiosperm Evolution显示文摘According to the classic doctrine of angiosperm evolution,the archetype carpel in angiosperms is of plicate form.However,this concept is facing increasing challenges from the systematics based on molecular data,which now takes ascidiate carpel as ancestral.This reorientation in evolutionary thinking cannot be fully achieved unless there is supporting fossil evidence.Here a fruit, named Liaoningfructus,is reported from the famous Yixian Formation(Early Cretaceous,125 Ma), which yielded several pioneer ang... | Xin WANG Gang HAN | 2011 | Acta Geologica Sinica(English Edition)2011，85，5： | 4 |
| 4 | New Genus and Species of Rhyacophilidae (Insecta:Trichoptera) from the Middle Jurassic of China显示文摘One new genus with a new fossil species,Declinimodus setulosus gen.et sp.nov.which was found in the Middle Jurassic Jiulongshan Formation of Daohugou,Inner Mongolia,China,are described and illustrated.The new species is assigned to the Rhyacophilidae according to buttonshaped of the 2nd segment of maxillary palp,and the forked R1(in the forewing,located near apex).These new discovery are the earliest fossil records of Rhyacophilidae,which providing important evident for the study of the origin and early evolution of Trichoptera. | GAO Yan YAO Yunzhi REN Dong | 2013 | Acta Geologica Sinica(English Edition)2013，87，6： | 2 |
| 5 | A Whole Plant Herbaceous Angiosperm from the Middle Jurassic of China显示文摘In contrast to woody habit with secondary growth,truthful herbaceous habit lacking secondary growth is restricted to angiosperms among seed plants.Although angiosperms might have occurred as early as in the Triassic and herbaceous habit theoretically may have been well adopted by pioneer angiosperms,pre-Cretaceous herbs are missing hitherto,leaving the origin of herbs and evolution of herbaceous angiosperms mysterious.Here we report Juraherba bodae gen.et sp.nov,a whole plant herbaceous angiosperm,from the Middle Jurassic(>164 Ma)at Daohugou Village,Inner Mongolia,China,a fossil Lagerstatten that is worldwide famous for various fossil finds.The angiospermous affinity of Juraherba is ensured by its enclosed ovules/seeds.The plant is small but complete,with physically connected hairy root,stem,leaves,and fructifications.The Middle Jurassic age recommends Juraherba as the earliest record of herbaceous seed plants,demanding a refresh look at the evolutionary history of angiosperms. | HAN Gang LIU Zhongjian LIU Xueling MAO Limi Frederic M.B.

| 6 | 中国中、新生代植物大化石新属记录(2001—2010)显示文摘记录2001—2010年间根据中国中、新生代植物大化石建立的新属25个(新生代的2个,中生代的23个),记录每一属的特征、模式种、地理分布及地质时代。对模式种的创建者、创建年代、所在文献的页码、图版、产地层位、标本保存状态、分类位置以及模式标本保存单位等作详细记录。另有一属(Tharrisia Zhou,Wu and Zhang)模式种的模式标本虽非产自中国,但该属是根据研究中国发现的材料修订含义笼统老属而从中区分出来的,所以也作了记录。 | 吴向午 | 2013 | 古生物学报2013，52，1： | 0 |
| 7 | Origin and evolution of green plants in the light of key evolutionary events显示文摘Green plants(Viridiplantae)are ancient photosynthetic organisms that thrive both in aquatic and terrestrial ecosystems,greatly contributing to the changes in global climates and ecosystems.Significant progress has been made toward understanding the origin and evolution of green plants,and plant biologists have arrived at the consensus that green plants first originated in marine deep-water environments and later colonized fresh water and dry land.The origin of green plants,colonization of land by plants and rapid radiation of angiosperms are three key evolutionary events during the long history of green plants.However,the comprehensive understanding of evolutionary features and molecular innovations that enabled green plants to adapt to complex and changeable environments are still limited.Here,we review current knowledge of phylogenetic relationships and divergence times of green plants,and discuss key morphological innovations and distinct drivers in the evolution of green plants.Ultimately,we highlight fundamental questions to advance our understanding of the phenotypic novelty,environmental adaptation,and domestication of green plants. | Zhenhua Zhang Xiaoya Ma Yannan Liu Lingxiao Yang Xuan Shi Hao Wang Runjie Diao Bojian Zhong | 2022 | Journal of Integrative Plant Biology2022，64，2： | 0 |
