1New 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
2A new Early Cretaceous dinosaur track assemblage and the first definite non-avian theropod swim trackway from China显示文摘The trackway of a swimming theropod (ichnogenus Characichnos) is reported from the Lower Cretaceous Feitianshan Formation of Sichuan, China. These swim tracks help confirm that non-avian theropods were capable of forging moderately deep bodies of water. The trackway occurs on the same surface as a typical walking trackway of a sauropod (ichnogenus Brontopodus). Both occurrences are the first reported from the Cretaceous of Sichuan, and the swim tracks are the first well-preserved example of a Characichnos trackway from China. Additionally, a theropod walking trackway and several ornithopod walking trackways (similar to the ichnogenus Caririchnium) occur in the same horizon. The ornithopod trackways show a parallel orientation, suggesting gregarious behavior of the trackmakers, which may have been iguanodontiforms and/or hadrosauriforms. The co-occurrence of theropod swim tracks and theropod walking tracks suggests a fluctuation of water depth within a distinct time span.XING LiDa LOCKLEY Martin G ZHANG JianPing MILNER Andrew R C KLEIN Hendrik LI DaQing PERSONS IV W Scott EBI JieFang 2013Chinese Science Bulletin2013,58,19:3
3Unusual 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

9新疆恐龙足迹的最早记录(英文)显示文摘尽管新疆地域辽阔,但其四足动物足迹在不久前仍是寥寥。近几年,这种情况得以改变,来自侏罗纪和白垩纪的四足动物足迹陆续被报道和描述,其形态可归入鸟类、非鸟恐龙和翼龙足迹。这里报道了中国科学院南京地质古生物研究所保存的新疆下侏罗统地层发现的第一个恐龙足迹。该足迹是一个小型兽脚类足迹,也是中国西北目前已知的最古老的恐龙足迹。标本暂时归入似张北足迹未定种(cf.Changpeipus isp.),它类似于常见的跷脚龙-实雷龙足迹丛(Grallator-Eubrontes plexus),该种类的足迹主宰着早、中侏罗世的中国,乃至全球之四足动物足迹群。邢立达 Martin G.

14A 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
15中国甘肃一例前足迹主导的翼龙足迹组合:对行为学的影响(英文)显示文摘翼龙是已知的、最早飞上天际的脊椎动物,目前已经发现了成千上万件化石,代表着这一大家族从晚三叠世到晚白垩世在全球范围内的蓬勃发展史.自2004年甘肃盐锅峡地区首次报道翼龙足迹以来,中国陆续发现了一批翼龙足迹化石,绝大多数的足迹点都保存了翼龙的前后足迹.2013年,我们在盐锅峡地区发现了至少20个翼龙前足迹的凸型足迹,而没有发现任何后足迹,这些足迹可归于一个单独翼龙遗迹属——Pteraichnus.这是中国第一次发现由前足迹主导的翼龙足迹组合,这可能反映了翼龙前后足迹在同等保存条件下的不同深度.更重要的是,盐锅峡的这批翼龙足迹与当地发现的大量虫迹相关,一些足迹甚至就保存在虫迹面上,这些虫迹包括Cochlichnus,Spongeliomorpha和Paleophycus,因此推断这批翼龙造迹者很可能以这些无脊椎动物造迹者为食.李大庆 邢立达 Martin G.

16Lower Cretaceous sauropod trackways from Lishui City and an overview of dinosaur dominated track assemblages from Zhejiang Province, China显示文摘A relatively small number of tetrapod tracksites from Zhejiang Province fills out the fossil record from that region,which is also known to have yielded both saurischian(titanosauriform, coelurosaur) and ornithischian(basal ornithopod, ankylosaurian) body fossils as well as dinosaurian eggs. We use photogrammetry and 3 D imaging to reinterpret the sauropod tracks from Lishui City, which revealed the existence of trackways. The track record from three documented sites in Zhejiang Province includes avian and non-avian theropod, sauropod, ornithopod and pterosaur tracks. Previous work showed that the purported new bird ichnospecies Dongyangornipes sinensis is a synonym of Uhangrichnus chuni, while we here consider Pteraichnus dongyangensis as a nomen dubium. Such 'provincial ichnotaxonomy' may mask similarities in the ichnofauna across large regions. In fact, we show that the ichnofauna is similar to that found in the Early Cretaceous elsewhere in China.Li-Da Xing Chun-Yong Chou Martin G.Lockley Anthony Romilio Hendrik Klein Nan Li W.

17Late Triassic sauropodomorph and Middle Jurassic theropod tracks from the Xichang Basin,Sichuan Province,southwestern China:First report of the ichnogenus Carmelopodus显示文摘Upper Triassic and Middle Jurassic strata of the Xichang Basin in Sichuan Province, southwestern China, yielded important dinosaur ichnofossils. From the Xujiahe Formation of the Yiguojiao tracksite, we report a Late Triassic footprint assemblage in China and the first discovery of diagnostic Triassic sauropodomorph tracks in this region. The tracks share a number of features in common with the ichnogenera Eosauropus(Late Triassic) and Liujianpus(Early Jurassic). The neighboring Bingtu tracksite is stratigraphically younger(Shaximiao Formation, Middle Jurassic) and preserves small tridactyl theropod tracks that represent the first occurrence of the ichnotaxon Carmelopodus in China and Asia. While these tracks are morphologically comparable to those from the Middle Jurassic type locality in North America, the specimens from China show the proximal margin of the digit IV impression in a more cranial position, which may indicate a trackmaker with a relatively short metatarsal IV. In addition to the skeletal record, the Carmelopodus footprints document the presence of small theropods in the dinosaur fauna of the Middle Jurassic Shaximiao Formation.Li-Da Xing Jin Ba Martin G.Lockley Hendrik Klein 5heng-Wu Yon Anthony Romilio Chun-Yong Chou Vtl.Scott Persons IV 2018Journal of Palaeogeography2018,7,1:0
18The new ichnotaxon Eubrontes nobitai ichnosp. nov. and other saurischian tracks from the Lower Cretaceous of Sichuan Province and a review of Chinese Eubrontes-type tracks显示文摘The Jiaguan Formation and the underlying Feitianshan Formation(Lower Cretaceous) in Sichuan Province yield multiple saurischian(theropod–sauropod) dominated ichnofaunas. To date, a moderate diversity of six theropod ichnogenera has been reported, but none of these have been identified at the ichnospecies level. Thus, many morphotypes have common 'generic' labels such as Grallator, Eubrontes, cf. Eubrontes or even 'EubrontesMegalosauripus' morphotype. These morphotypes are generally more typical of the Jurassic, whereas other more distinctive theropod tracks(Minisauripus and Velociraptorichnus) are restricted to the Cretaceous. The new ichnospecies Eubrontes nobitai ichnosp nov. is distinguished from Jurassic morphotypes based on a very wellpreserved trackway and represents the first-named Eubrontes ichnospecies from the Cretaceous of Asia.Li-Da Xing Martin G.Lockley Hendrik Klein Li-Jun Zhang Anthony Romilio W.Scott Persons IV Guang-Zhao Peng Yong Ye Miao-Yan Wang 2021Journal of Palaeogeography2021,10,3:0
19Largest dinosaur tracksite in China (Cretaceous, Zhaojue area, Sichuan Province): On the verge of destruction显示文摘The Zhaojue(ZJ)tracksites represent multiple steeply-inclined,track-bearing exposures in the clastic Feitianshan Formation of Sichuan Province that have been sequentially,excavated,mapped,expanded and destroyed,by quarrying,erosion or collapse,for almost three decades.The quarried area extends for more almost 1.0 km from north to south and-0.5 km from east to west.Four important track-bearing surfaces have been identified and identified as ZJ-Ⅰ,ZJ-Ⅱ,ZJ-ⅡN and ZJ-Ⅲ,some of which are newly exposed surfaces or expanded surfaces that were previously partially described.Others represent surfaces lost since they were first reported in papers published in 2014-2016.The ZJ-Ⅱ site represents a hugely expanded continuation of a much smaller track-bearing surface described in 2014.It was mapped using drone technology,and now represents the largest tracksite in China,with a minimum count of 933 recognizable tracks,and the longest recorded sauropod and ornithopod trackways from China(-80 m and-52 m respectively),which also reveal a pronounced change in the direction of trackmaker movement.The ZJ-Ⅱ surface represents the best Zhaojue paleo-census sample giving a count of 68 individuals from 61 trackways(37 ornithopod,10 theropod,14 sauropod)and isolated tracks(representing 7 individuals).Thus,ornithopods(both large and small trackmakers)represent-54%of the total number of trackways.The smaller ZJ-Ⅲ surface was mapped using traditional methods,and reveals at least 6 ornithopod-and 4 theropod trackways.Both the ZJ-Ⅱ and ZJ-Ⅲ surfaces reveal parallel ornithopod trackways suggestive of social or gregarious behavior.The combined data from all four Zhaojue surfaces reveal a total of 1928 tracks,and include a few previously reported pterosaurs and theropod swim tracks.The Zhaojue quarry complex provide a good example of multiple track-bearing sites(surfaces)that require long term study and monitoring to extract as much trackway data as possible before in situ physical evidence is lost.Lida Xing Martin G.Lockley Hendrik Klein W.Scott Persons IV Guangzhao Peng Yong Ye Miaoyan Wang 2021Geoscience Frontiers2021,12,5:0
20The Middle-Upper Jurassic dinosaur-pterosaur fauna in Shandong Province,China:Evidence from ichnology显示文摘Tracks previously examined between 2002 and 2015 from an incompletely-studied,and now partially lost tracksite site in the Santai Formation of Shandong Province were restudied based on new ex-cavations of additional surfaces.In contrast to the previous reports of tridactyl tracks,including Grallator,the present study discovered an additional assemblage of unequivocal pterosaur tracks(Pteraichnus)and a possible didactyl deinonychosaurian track.The age of the Santai Formation is controversial but it is probably Late Jurassic,which corresponds to the epoch when pterosaur tracks appear worldwide.Age interpretations,based on palynology and isotopic data,tentatively suggests an earlier Middle-Late Jurassic age and might suggest that the pterosaurian tracks are as old or somewhat older than any previously reported.Li-Da Xing Martin G.Lockley Bo-Lin Tong Hendrik Klein Chang Liu W.Scott Persons IV 2023Journal of Palaeogeography2023,12,3:0
