山西天镇—河北阳原晚白垩世沉积相与恐龙的埋藏环境

对山西天镇－河北阳原地区富念恐龙化石的晚白恶世灰泉堡组进行地层 相系统分析，结果表明，该沉积相属一套湖泊和扇三角洲沉积组合，并详细讨论了各岩相中的亚相和微相的基本特征。结合恐龙化石的产出层位及岩相特征，对恐龙的埋藏环境进行了初步研究，认为该恐龙埋藏群主要产在低能浅水的碱性氧化滨湖环境。     

辽宁北票首次发现初鸟类化石-东方吉祥鸟(Jixiangornis orientalis gen.et sp.nov.)

本文记述了辽宁北票义县组一件新的初鸟类（Avialae）化石，这是继中华神州鸟（Shenzhouraptor sinensis Ji et al.2002）之后初鸟类化石的又一发现。它以上颌无齿而具角质喙、胸骨发达且具龙骨突、前肢显著长于后肢等特征与始祖鸟（Archaeopteryx）不同，以后肢第Ⅰ趾爪已反转而与其它3趾对握等特征与神州鸟相区别，该化石被命名为东方吉祥鸟（新属、新种）（Jixiangornis orientalis gen.et sp.nov.）。中国辽西新近发现的中华神州鸟和东方吉祥鸟（新属、新种）目前是世界上最古老最原始真正具有角质喙和飞行能力的原始鸟类。     

京西早白垩世丸甲（昆虫纲，鞘翅目）化石

根据北京西山下白垩统卢尚坟组的甲虫化石，建立化石丸甲二新属三新种：Ｍｅｓｏｂｙｒｒｈｕｓｔａｎａｅｇｅｎ．ｅｔｓｐ．ｎｏｖ，Ｍｅｓｏｂｙｒｒｈｕｓｐａｒｖｕｓｇｅｎ．ｅｔｎｏｖ．和Ｆａｎｇｓｈａｎｅｌａｓｔｏｌｉｄａｇｅｎ．ｅｔｓｐ．ｎｏｖ．．初步探讨了丸甲科昆虫的演化，认为丸甲科是鞘翅目中很古老的一类，和其它科关系不大，自中生代后期以来演化十分缓慢     

恐龙世界中的异类——二连巨盗龙

2007年6月,我国科学家在英国《Nature》(自然)杂志上报道了发现于我国内蒙古二连盆地晚白垩世地层中的一种巨型似鸟恐龙化石。这个被命名为二连巨盗龙的恐龙新种引起了世界各国媒     

Official： China might have A（H1N1） Influenza vaccine by July

Chinese scientists have named the country＇s most recently discovered meat-eating dinosaur after its centuries-old Great Wall.
Xiongguanlong, the name of an early Cretaceous predator whose fossilized remains were found near the Jiayuguan, the western start point of the 8,850-km-long Ming Dynasty Great Wall, literally means ＂Dinosaur of the Grand Pass＂, said Li Daqing, a paleontologist with Gansu Provincial Bureau of Geo-Exploration and Mineral Development, on Friday.     

Dinosaur eggs and dinosaur egg-bearing deposits （Upper Cretaceous） of Henan Province, China： Occurrences, palaeoenvironments, taphonomy and preservation

The Upper Cretaceous dinosaur egg-bearing deposits in Henan Province, central China are divided into three formations in ascending order: Gaogou, Majiacun and Sigou. The Gaogou Formation belongs to alluvial fan deposits containing the fossil dinosaur egg assemblage of Faveoloolithus, Dendroolithus, Dictyoolithus, Paraspheroolithus and Longiteresoolithus. The Majiacun Formation is interpreted as braided stream to meandering stream deposits with assemblage of Ovaloolithus,Paraspheroolithus,Placoolithus,Dendroolithus,Prismatoolithus, rare Youngoolithus and Nanhiungoolithus. The Sigou Formation is shallow lacustrine/palustrine to low-sinuosity river sedimentary rocks with assemblage of Macroolithus,Elongatoolithus, Ovaloolithus and Paraspheroolithus.To date, 37 oospecies, 13 oogenera and 8 oofamilies of dinosaur eggs have been distinguished. Autochthonous dinosaur eggs are preserved in the floodplain deposits, whereas allochthonous and parautochthonous dinosaur eggs are preserved in the alluvial fans. This suggests that river floodplains are the best environments for the preservation of numerous autochthonous dinosaur eggs. The preservation of most dinosaur eggs in brown to red calcic palaeosoils, muddy siltstones or mudstones suggests that the paleoclimate of the nesting area was semiarid. The presence of gray and green mudstone and coal layers, however, indicates that there existed an ephemeral subhumid climate during the middle and Late Cretaceous. It is suggested that such a climate was favorable for the development of meandering streams in a vegetated environment.     

西藏革吉县赛利普地区捷嘎组地层古生物及沉积环境

在西藏革吉县赛利普地区测制了多条捷嘎组剖面,详细描述了阿母弄勒捷嘎组剖面,首次将区内捷嘎组细分为两个岩性段,讨论了捷嘎组的岩性组合特征及横向变化规律.在捷嘎组内建立了一个圆笠虫生物组合带和一个腹足类生物组合带,确定捷嘎组的时代为早白垩世阿普特晚期至阿尔布期.认为赛利普地区捷嘎组从早到晚空间上由北向南火山活动趋于强烈,出现了偶发火山碳酸盐台地→间歇火山碳酸盐台地→火山爆发-溢流相的空间变化规律.     

叩问恐龙蛋——鸟类与恐龙有怎样的亲缘关系?

鸟类的起源问题是生物学研究的热点领域,涉及鸟类的形态结构、飞行和羽毛等多方面内容。随着越来越多重要化石的发现,鸟类的恐龙起源学说已经逐渐为学术界所接受。特别是近年来,在我国早白垩世热河生物群以及侏罗纪地层中发现了许多保存精美的带毛恐龙、中生代鸟类化石等,     

鲁西隆起蒙山晚白垩世-新生代抬升的裂变径迹证据

 研究晚白垩世以来蒙山的抬升对全面认识鲁西隆起区的构造演化具有重要的意义。对采自蒙山山脉的6个岩石样品进行了磷灰石/锆石裂变径迹测年及热历史模拟分析。分析结果表明蒙山自晚白垩世开始快速抬升,经历了70~43 Ma和32~20 Ma两个快速抬升阶段,并且蒙山的抬升表现出加速抬升的特征。晚白垩世以来蒙山的快速抬升与其毗邻的泰山有着较好的对应关系,蒙山的整体抬升略早于泰山,并且鲁西隆起的抬升表现出由南向北的抬升序列。蒙山的两期快速抬升事件很好地对应了济阳坳陷在这两个时期经历的构造沉降和区域隆升过程,表明新生代蒙山的快速抬升与济阳坳陷的构造演化有着良好的隆拗耦合关系。
