| 1 | A Review of the Tetrapod Track Record in China,with Special Reference to Type Ichnospecies:Implications for Ichnotaxonomy and Paleobiology显示文摘切开并且 lumping 是在脊椎动物的永久问题,特别恐龙, ichnotaxonomy。中国恐龙 ichnotaxonomy,在 1940 开始了,提供一系列有趣的案例研究,加亮历史、可疑的 ichnotaxonomy 的双问题。中国中生代四足动物的轨道类型被放进 63 ichnospecies (一个三叠纪, 28 侏罗记,和 34 白垩纪) ,从中国识别的其它,非类型 ichnospecies 或 ichnotaxa 独占。(83%) 52 这 63 四足动物的 ichnospecies 被放在 monospecific ichnogenera。在 ichnogenus 水平,我们由认出 nomina dubia 或由从 53 恐龙的 ichnogenera (32% 减小) 的表的 synonymy17 的 pruneeither,离开我们认为有效的 36 ichnotaxa。大多数切割影响侏罗记 theropod ichnotaxa,它仅仅从 23 被归结为九因为大多数 ichnogenera 是 Grallator 和 Eubrontes 的主观年轻同义词。更少中国白垩纪 ichnotaxa (仅仅 21 ichnogenera 中的六个) 是明显的 nomina dubia 或主观同义词,建议更大的东方亚洲人 endemism 在期间这次。因为 ichnospecies 差别是微妙的,我们暂时地作为同种的 ichnospecies 的有效未解决的详细比较分析保留 ichnospecies。这合成是长迟到的并且对历史、省的 ichnotaxonomy 的地址问题必要,它严重地在空间和时间妨碍四足动物的 ichnofaunas 的比较。 | Martin G.LOCKLEY LI Jianjun LI Rihui Masaki MATSUKAWA Jerald D.HARRIS XING Lida | 2013 | Acta Geologica Sinica(English Edition)2013，87，1： | 19 |
| 2 | 记河北赤城上侏罗统-下白垩统土城子组窄足龙-巨齿龙(兽脚类恐龙)足迹组合及其古生态学意义(英文)显示文摘记述了河北省赤城县落凤沟化石点163个窄足龙足迹(Therangospodus isp.)。当该地区洪水泛滥时,同样的造迹者留下了5个游泳迹。一个异常大的足迹和一道疑似尾迹被归入巨齿龙足迹(Megalosauripus isp.)。土城子组7个主要足迹化石点表明,兽脚类的似鹬龙足迹型(Grallator morphotype)占据主导地位,这些足迹型的大小在各个足迹化石点都有着特定的范围。如果这些大小不同的足迹属于同一种造迹者,则暗示着同年龄的成员在特定年龄时会共同栖息在一起,在动物行为学上类似现生的一些蜥蜴和短吻鳄;如果这些足迹由不同的造迹者组成,则暗示着不同大小的种(主要表现在小型动物)可能拥有自己的领地,并特意避免与其他动物(特别是大型动物)相接触,在动物行为学上类似现生的肉食性哺乳动物。 | 邢立达 Jerald D.HARRIS Gerard D.GIERLINSKI | 2011 | 古脊椎动物学报2011，49，4： | 18 |
| 3 | Avian skulls represent a diverse ornithuromorph fauna from the Lower Cretaceous Xiagou Formation, Gansu Province, China显示文摘We describe six specimens consisting of cranial remains and associated partial presacral axial series belonging to ornithuromorph birds from the Changma locality of the Lower Cretacous Xiagou Formation of northwestern Gansu Province,China.Comparison among specimens is limited by the paucity of overlapping elements,their differing exposed views,and,in some specimens,poor preservation.Despite this,three separate taxa are represented,evidenced by differences in their dentary dentitions:one specimen is edentulous,another has sharp,closely spaced,relatively high-crowned and peg-ike teeth,and a third preserves blunt,relatively lowcrowned teeth placed in a communal groove,a morphology previously reported among adult birds only in Hesperornithiformes.We propose that the high-crowned specimen may be referred to Gansus yumenensis based on shared similarities with the closely related Iteravis huchzermeyeri,including a very similar dentition and an edentulous premaxilla with elongate,unfused frontal processes and no palatal processes.The two other specimens are considered new taxa,for which we erect the names Meemannavis ductrix gen.et sp.nov.and Brevidentavis zhangi gen.et sp.nov.These new specimens confirm that the Changma locality is dominated by ornithuromorph birds and contribute to a better understanding of this important avifauna.The observed variation in dental morphology hints at trophic diversity like that observed in ornithuromorphs from the penecontemporaneous Jehol Group of northeastern China. | Jingmai.K.O'Connor Thomas A.Stidham Jerald D.Harris Matthew C.Lamanna Alida M.Bailleul Han Hu Min Wang Hai-Lu You | 2022 | Journal of Systematics and Evolution2022，60，5： | 0 |
