| 1 | A New Basal Titanosaur (Dinosauria: Sauropoda) from the Early Cretaceous of China显示文摘A new dinosaur of Early Cretaceous age was recently discovered from the Mazongshan area of northwesternGansu Province, China. The new dinosaur represents a new genus and species of Sauropoda, and is among the most basalmembers of Titanosauria. Its finding also suggests that titanosaurs might have originated in Asia no later than the EarlyCretaceous. | YOUHailu TANGFeng LUOZhexi | 2003 | Acta Geologica Sinica(English Edition)2003,77,4: | 17 |
| 2 | A New Hadrosauriform Dinosaur from the Early Cretaceous of Gansu Province,China显示文摘一条新基础 hadrosauriform 恐龙, Xuwulong yueluni 情报。et sp。nov,包括完全的头盖骨,几乎完全的轴的骨骼,和完全的左骨盆的腰带基于一个明白表示的标本被报导。标本在 Jiuquan 区域从早白垩纪 Yujingzi 盆被恢复,西北的中国的 Gansu 省。Xuwulong 在之中最 hadrosauriform 恐龙的基础成员,并且在在侧面的看法和铺平与的 mandible 的关节的表面有齿骨的塑造 V 的喙的结束由它的唯一的更低的颚区分了齿骨分支中间高度,以及一扩大并且 downturned prepubic 过程。包括 Xuwulong,三基础 hadrosauriforms 在 Mazongshan 区域从早白垩纪 Xinminpu 组被发现了,成为学习起源和 duck-billed 恐龙的早进化是一个重要区域。 | YOU Hailu LI Daqing LIU Weichang | 2011 | Acta Geologica Sinica(English Edition)2011,85,1: | 8 |
| 3 | 中国东部晚白垩世恐龙化石集群埋藏特征及国内外对比显示文摘运用埋藏学与沉积地质学的研究方法与手段,对中国东部晚白垩世具有恐龙化石集群埋藏盆地中恐龙骨骼化石的埋藏地层层序与年代、埋藏骨骼化石特征、骨骼化石埋藏类型及其埋藏成因等进行了分析与总结,并将其产出时代、埋藏相、埋藏特征与国外进行了对比研究。研究认为:中国东部与国外相比,虽然化石产出的具体时期有所差异,但从恐龙种群、埋藏相及沉积地层学等方面均具有相似性,反映了晚白垩世全球古环境、古生态及古气候的相似性。(1)中国晚白垩世恐龙骨骼化石埋藏事件可分为早期与晚期2个阶段:早期的Cenomanian期与晚期的Santonian-Maastrichtian期。而国外晚白垩世恐龙骨骼化石埋藏事件只发生在晚期,在美洲及蒙古国发生在Campanian晚期,在欧洲则为Campanian-Maastrichtian期的过渡时期及Maastrichtian期。(2)中国埋藏骨骼化石种属以鸟脚类鸭嘴龙科与兽脚类恐龙为主,它们埋藏于紫红色地层中,埋藏环境主要为冲积扇与河流环境;美洲以鸭嘴龙科为主,欧洲与蒙古国的种群各地不相同,都埋藏于紫红色岩石地层中,埋藏环境主要为河流—泛滥平原。骨骼在不同沉积相组合地层中埋藏学特征各异,与古地理、古生态及古环境密切相关。(3)结合盆地中的化石埋藏学特征与盆地演化特征,总结了恐龙化石埋藏类型主要有原地埋藏与异地埋藏,盆地古地理格局变动、火山活动、古温度升高及古地震等事件的综合作用是可能的埋藏成因,并提出了恐龙化石的埋藏模式。此研究为揭示中国东部乃至全球晚白垩世的古地理、古气候及古生态环境及恐龙灭绝原因的探讨提供了新的材料与证据。 | 王能盛 旷红伟 柳永清 彭楠 许欢 章朋 汪明伟 王宝红 安伟 | 2015 | 古地理学报2015,17,5: | 5 |
| 4 | Description and Phylogenetic Position of Dinosaur Eggshells from the Luanchuan Area of Western Henan Province,China显示文摘这里,我们在西方的河南省省在 Luanchuan 区域的 Qiupa 形成(上面的白垩纪) 从一个新石块地区检验 145 恐龙蛋壳,中国。蛋壳显示 elongatoolithid 宏 -- 并且外部表面,二 ultrastructural 层和连续的层上的微观结构,包括的山脉和节点。系统发生的分析证明 Luanchuan 蛋壳属于 ooclade Elongatoolithidae。在 Elongatoolithidae,到全部蛋壳的 mammillary 层的厚度比率,和 Luanchuan 的孔以内,蛋壳比得上 oogenera Macroolithus 和 Elongatoolithus。为 Luanchuan 蛋壳的分类身份没有直接证据;然而,他们被 oviraptorids 多半与已知的 oviraptorid 鸡蛋基于他们的种系发生的位置和他们的类似生。 | Kohei TANAKA LU Junchang Yoshitsugu KOBAYASHI Darla K.

| 5 | A New Nodosaurid Ankylosaur from the Chaochuan Formation of Dongyang, Zhejiang Province, China显示文摘Dongyangopelta yangyanensis gen. et sp. nov. from the Chaochuan Formation (Albian-Cenomanian) of Dongyang, Zhejiang Province, China is characterized: the convex anterior surface of the first presacral rod centrum strongly inflates laterally and slightly curves posteriorly; the fused pelvic shield composes of larger pebble-shaped bosses, defined by smaller tubercles or flat stretches of bone; most osteoderms are heavily roughened with notches and grooves for dermal attachment along the edge; domed triradiate osteoderm is present; sigmoid curvature of the dorsal surface of the ilium is present; the preacetabular process curves lateroventrally at the anterior end and has a shallow groove in the edge of the lateral and anterior ends and strong lateromedial expansion of the distal femur. The femoral head is well separated from the greater trochanter, indicating that Dongyangopelta is a nodosaurid ankylosaur, the second from southeast China. Phylogenetic analysis also positions this taxon in the Nodosauridae clade. Dongyangopelta differs from Zhejiangosaurus in the characters of presacral rod, ilium, and femur. Dongyangopelta represents the first ankylosaur outside North America and Europe that definitively possesses a pelvic shield with fused armor. | CHEN Rongjun ZHENG Wenjie Yoichi AZUMA Masateru SHIBATA LOU Tianliang JIN Qiang JIN Xingsheng | 2013 | Acta Geologica Sinica(English Edition)2013,87,3: | 1 |
