1重庆晚侏罗世两处兽脚类足迹组合与四川盆地侏罗纪地层(英文)显示文摘重庆市已报道了4处侏罗纪的恐龙足迹点,包括下侏罗统珍珠冲组的大足化石点,该地点发现了中国迄今最古老的蜥脚类行迹;另外两处化石点(南岸和金鸡)的层位曾被视为中或上侏罗统,这里首次将其确认为上侏罗统上沙溪庙组;第4处化石点(成渝), 本文全部作者目前都未曾观察,这里不做描述。南岸化石点是南岸重庆足迹(Chongqingpus nananensis)模式标本的所在地,位于重庆市中心,曾发现过大量兽脚类足迹,如今已消逝在城市化进程中。幸运的是,这批标本被保存于重庆自然博物馆,本文作者曾前后两次对其进行研究,并得出文中的结论。南岸重庆足迹为中型足迹(平均长约29 cm), 最可能被卡岩塔足迹(Kayentapus)所囊括,这批标本中有一些保存着边界不清的拇趾迹。该化石点的其他足迹被归于似异样龙足迹(cf. Anomoepus)。其他较小的、来自重庆市周边中侏罗统中部的足迹此前已被归于跷脚龙足迹(Grallator)。金鸡化石点保存了一条孤立的兽脚类行迹,因其粗壮的特征而被暂时归于似窄足龙足迹(cf. Therangospodus)。金鸡点的行迹也保存了非连续出现的拇趾迹。虽然重庆市和四川盆地及其周边更广泛地区之侏罗纪地层发现的兽脚类足迹日渐增多,但要明确其确切地质年龄及有效的足迹分类依然需要进一步工作。这是因为侏罗纪的恐龙足迹尽管丰富,但显示出连续变化的形态学特征,而保存状况的变化更使其难以在时间与空间上做出定义与鉴别。邢立达 Martin G.

2Evaluating the management of anaphylaxis in US emergency departments:Guidelines vs.practice显示文摘BACKGROUND:Anaphylaxis is characterized by acute episodes of potentially life-threatening symptoms that are often treated in the emergency setting.Current guidelines recommend:1) quick diagnosis using standard criteria;2) first-line treatment with epinephrine;and 3) discharge with a prescription for an epinephrine auto-injector,written instructions regarding long-term management,and a referral(preferably,allergy) for follow-up.However,studies suggest low concordance with guideline recommendations by emergency medicine(EM) providers.The study aimed to evaluate how emergency departments(EDs) in the United States(US) manage anaphylaxis in relation to guideline recommendations.METHODS:This was an online anonymous survey of a random sample of EM health providers in US EDs.RESULTS:Data analysis included 207 EM providers.For respondent EDs,approximately 9%reported using agreed-upon clinical criteria to diagnose anaphylaxis;42%reported administering epinephrine in the ED for most anaphylaxis episodes;and <50%provided patients with a prescription for an epinephrine auto-injector and/or an allergist referral on discharge.Most provided some written materials,and follow-up with a primary care clinician was recommended.CONCLUSIONS:This is the first cross-sectional survey to provide 'real-world' data showing that practice in US EDs is discordant with current guideline recommendations for the diagnosis,treatment,and follow-up of patients with anaphylaxis.The primary gaps are low(or no) utilization of standard criteria for defining anaphylaxis and inconsistent use of epinephrine.Prospective research is recommended.W.Scott Russell Judith Rosen Farrar Richard Nowak Daniel P.Hays Natalie Schmitz Joseph Wood Judi Miller 2013World Journal of Emergency Medicine2013,4,2:4
3New Early Cretaceous Pterosaur-Bird Track Assemblage from Xinjiang, China:Palaeoethology and Palaeoenvironment显示文摘A pterosaur-bird track assemblage from a sandstone-siltstone-mudstone sequence of the Lower Cretaceous Tugulu Group of Xinjiang comprises the first pterosaur track record from this province and the largest specimen thus far known from China.The pterosaur tracks are assigned to the ichnogenus Pteraichnus based on the triangular overall-shape,the four elongate digit traces and the robust manual digit trace III.Supposed trackmakers were dsungaripterid pterodactyloids whose skeletal remains are well known from the Tugulu Group.The bird tracks that occur on the same surface,are those of typical shorebirds,known from different other localities in southeast Asia.The congruence with Koreanaornis dodsoni described from the same stratigraphic level justifies an assignment to this ichnospecies.This is a further evidence of the co-occurrence of pterosaurs and birds in a typical lakeshore environment with possible seasonal alteration of water supply and aerial exposure indicated by wave ripples,mudcracks and repeated cycles of coarse to fine sediment.Pterosaurs and birds frequented the shoreline and may have fed also on the numerous invertebrates such as the Scoyenia tracemaker that left abundant burrows.HE Qing XING Lida ZHANG Jianping Martin G.LOCKLEY Hendrik KLEIN W.Scott PERSONS IV QI Liqi JIA Chengkai 2013Acta Geologica Sinica(English Edition)2013,87,6:4
4Unusual dinosaur trackway preservation as clues to paleo-landscape and behavior from the Lower Cretaceous Luohe Formation,Shaanxi Province,China显示文摘Poorly preserved tracks have limited ichnotaxonomic or biotaxon utility,but may reveal useful information about the paleoenvironment,behavior and track taphonomy.Eight mostly parallel to sub parallel trackway segments(T1–T8)were registered on a truncation surface in the Lower Cretaceous Luohe Formation of Shaanxi Province.These attest to the passage of several bipeds,probably all theropods,in a paleo-contour-parallel,south-north direction in an arid setting.Quality of preservation in these trackways is poor,but notably superior in two additional trackways(T9–T10)on a foreset surface.Trackway T9 indicates a didactyl trackmaker,probably a deinonychosaurian,heading north to south.This is the 13th report of deinonychosaurian tracks from the Lower Cretaceous of China.If any or all the eight south-north oriented trackway segments represent continuations of other segments in the same trackways,the total number of individual trackmakers heading in this direction may have been as lowas three.Although the trackway pattern and sedimentological evidence could indicate a physically controlled pathway influencing the direction taken by these trackmakers,the possibility that the trackways also represented small social or gregarious group cannot be ruled out.Lida Xing Martin G.Lockley Yongzhong Tang Hendrik Klein W.Scott Persons IV Miaoyan Wang Xingwen Li Hao Wu 2021Geoscience Frontiers2021,12,2:2

8Dragon Tails:Convergent Caudal Morphology in Winged Archosaurs显示文摘In the tails of dromaeosaurid dinosaurs and rhamphorhynchid pterosaurs, elongate osteological rods extend anteriorly from the chevrons and the prezygapophyses. These caudal rods are positioned in parallel and are stacked dorsoventrally. The fully articulated and three-dimensionally preserved caudal series of some dromaeosaurid specimens show that individually these caudal rods were flexible, not rigid as previously thought. However, examination of the arrangement of the caudal rods in cross-section indicates that the combined effect of multiple caudal rods did provide substantial rigidity in the dorsoventral, but not in the lateral, plane. The results of digital muscle reconstructions confirm that dromaeosaurids and rhamphorhynchids also shared greatly reduced caudofemoral muscles in the anterior tail region. The striking similarities between the tails of dromaeosaurids and rhamphorhynchids suggest that both evolved under similar behavioral and biomechanical pressures. Combined with recent discoveries of primitive deinonychosaurs that phylogenetically bracket the evolution of dromaeosaurid caudal rods between two arboreal gliding/flying forms, these results are evidence that the unique caudal morphologies of dromaeosaurids and rhamphorhynchids were both adaptations for an aerial lifestyle.W.Scott PERSONS IV Philip J.CURRIE 2012Acta Geologica Sinica(English Edition)2012,86,6:1

16A probable tyrannosaurid track from the Upper Cretaceous of southern China显示文摘A large number of Upper Cretaceous(Maastrichtian)dinosaur skeletal fossils have been found in the Nanxiong Basin and adjacent Ganzhou area,including those of theropods,sauropods and hadrosaurids.However,known dinosaur ichnoassemblages from the Nanxiong Basin partly indicate a different fauna,with dominating large-and medium-sized ornithopods,theropods,and pterosaurs(1,2)This is one of many known examples where trace and body fossil assemblages from the same formation or geologically discrete region show a different composition.Palecological and paleobiogeographical analyses therefore should consider data from both,before any conclusions can be drawn.Formations can be classified according to the relative degree of similarity or congruity(or difference/incongruity)between trace and body fossils into the 5 categories proposed by Lockley[3].Lida Xing Kecheng Niu Martin G.Lockley Hendrik Klein Anthony Romilio W.Scott Persons IV Stephen L.Brusatte 2019Science Bulletin2019,64,16:1
