In order to better constrain its evolution, two granodioritic 32 plutons of the Jiaodong Peninsula have been chosen as targets for a time-constrained 33 palaeomagnetic study. Indeed, plutons are devoid of visible deformation, did not experience 34 rotation along horizontal axis and are precisely dated by U/Pb and 40 Ar/ 39 Ar methods. 35 Multidomain (MD) magnetite has been identified as the principal magnetic remanent carrier. 36 The interpolation of existing and new U/Pb and 40 Ar/ 39 Ar ages revealed that characteristic 37 remanent magnetisation was acquired in a narrow range of 116 ± 2 Ma. Twenty out of 27 sites 38 present stable magnetic directions calculated from high-temperature or high-coercive 39 components. The observations of the solo normal magnetic polarity for this palaeomagnetic 40 collection and of the magnetic remanent age consistent with the Cretaceous Normal 41 Superchron (CNS) argue that the characteristic magnetic remanence may be considered as 42 primary. Detailed field observations of the intrusive relationship between the plutons and 43 country rocks and Anisotropy of Magnetic Susceptibility (AMS) study reveal the absence of 44 the subsequent deformation of plutons, or rigid rotation of plutons along a horizontal axis. 45 Two palaeomagnetic poles have been therefore calculated from these plutons. Among 12 out 46 15 Cretaceous palaeomagnetic poles, including the two new poles provided by this study, 47 from the Jiaodong Peninsula and on both sides of Tan-Lu and Muping-Jimo faults are 48 statistically consistent. As a result, the Jiaodong Peninsula behaved as a rigid block as internal 49 deformation appears negligible. The remaining three derived poles are probably due to the 50 secular variation or/and the vicinity of fault zones near of the palaeomagnetic sampling site. 51 Thus, they can not be applied to the peninsula-scaled tectonics. Comparison of these time- 52 constrained Cretaceous palaeomagnetic results of the Jiaodong Peninsula with those of North 53 China Block (NCB) indicate that the Jiaodong Peninsula was rigidly attached to NCB since, 2 54 at least, the Cretaceous as residual difference is clearly insignificant with respect to the error 55 brackets. These new palaeomagnetic results confirm that the relative clockwise (CW) rotation 56 of Eastern Liaoning-Korea Block (ELKB) with respect to NCB does not affect the Jiaodong 57 Peninsula as a rigid block, nevertheless, some tectonic structures have been reactivated since 58 Cenozoic and local rotations could be produced. This palaeomagnetic study reveals that the 59 Late Mesozoic extension in Eastern Asia is heterogeneously expressed in time and space. The 60 complete understanding of the mechanism(s) of this extensional event needs further 61 multidisciplinary investigations. 62 63 Key-words: Eastern China, Late Mesozoic extension, palaeomagnetism, granitic pluton, 64 magnetic remanent age, Cretaceous, Shandong Peninsula. 65 66 1. Introduction 67 After a succession of Palaeozoic orogenies and a relative tectonic quietude (e.g., 68 Kusky et al., 2007), Eastern Asia has experienced a major extensional event and lithospheric 69 thinning during Late Mesozoic and Cenozoic times that extend from South China to Lake 70 Baikal south-northwardly and from the Japanese Islands to Gobi desert east-westwardly (e.g., 71 Gilder et al., 1991; Menzies et al., 1993; Davis et al., 1996; Griffin et al., 1998; Ren et al., 72 2002; Lin et al., 2003; Meng, 2003; Lin and Wang, 2006; Zhai et al., 2007; Daoudene et al., 73 2009; Chen, 2010). Numerous geological observations argue for the importance of this major 74 extensional event, including: (1) formation of intracontinental extensional sedimentary basins 75 (e.g., Liu, 1986; Ma and Wu, 1987; Ren et al., 2002), (2) emplacement of widespread 76 volcanism and plutonism (Wu et al., 2005a, b, 2007) and more importantly (3) exhumation of 77 Metamorphic Core Complexes (MCC; Davis et al., 1996; Darby et al., 2004; Liu et al., 2005; 78 Lin et al., 2008; Charles et al., 2011). It is noteworthy that most of these features developed 3 79 during the Late Jurassic-Early Cretaceous (e.g., Ren et al., 2002; Liu et al., 2005; Wu et al., 80 2005a; Wang et al., 2006; Lin et al., 2008). Various models proposed to account for the 81 geodynamical causes for this major extensional event are still highly debated (e.g., Meng, 82 2003; Lin and Wang, 2006; Zhai et al., 2007): (1) back-arc extension induced from Palaeo- 83 Pacific plate subduction (e.g., Watson et al., 1987; Li, 2000; Zhou and Li, 2000; Ren et al., 84 2002), (2) post-orogenic collapse (Meng, 2003), (3) lithospheric delamination (Lin and Wang, 85 2006), or (4) mantle plume (Okada, 1999). 86 The Late Mesozoic to Cenozoic extensional event affected eastern Asia composed of a 87 set of continental blocks amalgamated during previous orogenies (e.g., Mattauer et al., 1985; 88 Kusky et al., 2007). The knowledge of kinematic histories of these blocks during Late 89 Mesozoic times can provide essential informations to better understand relations between 90 rigid blocks movement of and development of major extensional crustal structures. In fact, 91 according to palaeomagnetic and structural studies, Lin et al. (2003) and Liu et al. (2005) 92 have proposed that clockwise (CW) rotation of the Eastern Liaoning-Korean block (ELKB) 93 with respect to the North China Block (NCB) was accommodated by the exhumation of South 94 Liaodong and Yiwulüshan MCCs and the opening of Songliao-Xialiaohe basin (see Fig. 1 in 95 Lin et al., 2003). Moreover, the Euler pole of this CW rotation is located in the southern end 96 of Bohai bay (Lin et al., 2003). Such a CW rotation is also invoked by Huang et al. (2007) for 97 the easternmost and southeastern parts of the Jiaodong Peninsula (Shandong Province, NE 98 China) to the south of the ELKB and the Bohai bay, since Early Cretaceous. As a result, 99 Huang et al. (2007) assume that the Jiaodong Peninsula cannot be considered as a rigid part of 100 the NCB. However, an other palaeomagnetic study carried out in the peninsula showed that 101 the northern part of the Jiaodong did not experience any rotation nor latitudinal displacement 102 since Cretaceous times with respect to NCB (Gilder et al., 1999). These discrepancies have 103 major consequences on the understanding of the mechanism of the Mesozoic extension in the 4 104 eastern Asia and thus, need to be clarified. The aim of the present paper is to better 105 palaeomagnetically constrain the kinematics of the Jiaodong Peninsula with well-dated 106 ferromagnetic granodioritic plutons (i.e. the Weideshan and Haiyang massifs; Fig. 1 and 107 Table 1). This palaeomagnetic study has been carried out with careful structural and AMS 108 analyses of both plutons and country rocks. New palaeomagnetic and time constraints are thus 109 provided to better understand the Late Mesozoic extension of Eastern Asia. 110 111 2. Geological background 112 2.1. Jiaodong Peninsula 113 The Jiaodong Peninsula, in Shandong Province (NE China), is located along the 114 southeastern margin of the North China Block (NCB; Fig. 1a). This area is delimited to the 115 west by the NNE-trending crustal-scale Tancheng-Lujiang (or Tan-Lu) fault (Fig. 1a), and to 116 the south by the Sulu ultrahigh-pressure metamorphic belt which was tectonically active 117 during Triassic times (e.g., Faure et al., 2001, 2003). To the northwest of the Jiaodong 118 Peninsula, Precambrian basement rocks are uncomformably covered by Mesozoic to 119 Cenozoic sedimentary and volcanic series (Fig.

  • A New Caenagnathid Dinosaur from the Upper Cretaceous Wangshi
    www.nature.com/scientificreports OPEN A new caenagnathid dinosaur from the Upper Cretaceous Wangshi Group of Shandong, China, with Received: 12 October 2017 Accepted: 7 March 2018 comments on size variation among Published: xx xx xxxx oviraptorosaurs Yilun Yu1, Kebai Wang2, Shuqing Chen2, Corwin Sullivan3,4, Shuo Wang 5,6, Peiye Wang2 & Xing Xu7 The bone-beds of the Upper Cretaceous Wangshi Group in Zhucheng, Shandong, China are rich in fossil remains of the gigantic hadrosaurid Shantungosaurus. Here we report a new oviraptorosaur, Anomalipes zhaoi gen. et sp. nov., based on a recently collected specimen comprising a partial left hindlimb from the Kugou Locality in Zhucheng. This specimen’s systematic position was assessed by three numerical cladistic analyses based on recently published theropod phylogenetic datasets, with the inclusion of several new characters. Anomalipes zhaoi difers from other known caenagnathids in having a unique combination of features: femoral head anteroposteriorly narrow and with signifcant posterior orientation; accessory trochanter low and confuent with lesser trochanter; lateral ridge present on femoral lateral surface; weak fourth trochanter present; metatarsal III with triangular proximal articular surface, prominent anterior fange near proximal end, highly asymmetrical hemicondyles, and longitudinal groove on distal articular surface; and ungual of pedal digit II with lateral collateral groove deeper and more dorsally located than medial groove. The holotype of Anomalipes zhaoi is smaller than is typical for Caenagnathidae but larger than is typical for the other major oviraptorosaurian subclade, Oviraptoridae. Size comparisons among oviraptorisaurians show that the Caenagnathidae vary much more widely in size than the Oviraptoridae. Oviraptorosauria is a clade of maniraptoran theropod dinosaurs characterized by a short, high skull, long neck and short tail.

Borinder and the Department of Earth Sciences, Uppsala University Published at Department of Earth Sciences, Uppsala University (www.geo.uu.se), Uppsala, 2015 Abstract Postcranial Anatomy of Tanius Sinensis Wiman, 1929 (Dinosauria; Hadrosauroidea) Niclas H. Borinder Tanius sinensis Wiman, 1929 was one of the first hadrosauroid or “duck-billed” taxa erected from China, indeed one of the very first non-avian dinosaur taxa to be erected based on material from the country. Since the original description by Wiman in 1929, the anatomy of T. sinensis has received relatively little attention in the literature since then. This is unfortunate given the importance of T. sinensis as a possible non-hadrosaurid hadrosauroid i.e. a member of Hadrosauroidea outside the family of Hadrosauridae, living in the Late Cretaceous, at a time when most non-hadrosaurid hadro- sauroids had become replaced by the members of Hadrosauridae. To gain a better understanding of the anatomy of T. sinensis and its phylogenetic relationships, the postcranial anatomy of it is redescribed. T. sinensis is found to have a mosaic of basal traits like strongly opisthocoelous cervical vertebrae, the proximal end of scapula being dorsoventrally wider than the distal end, the ratio between the proximodistal length of the metatarsal III and the mediolateral width of this element being greater than 4.5.

  • Immigrant Species, Or Native Species?
    The Journal of Paleontological Sciences: JPS.C.2017.01 TESTING THE HYPOTHESES OF THE ORIGIN OF TYRANNOSAURUS REX: IMMIGRANT SPECIES, OR NATIVE SPECIES? __________________________________________________________________________________________________________________ Chan-gyu Yun Vertebrate Paleontological Institute of Incheon, Incheon 21974, Republic of Korea & Biological Sciences, Inha University, Incheon 22212, Republic of Korea [email protected] __________________________________________________________________________________________________________________ Abstract: It is an undoubtable fact that Tyrannosaurus rex is the most iconic dinosaur species of all time. However, it is currently debatable whether this species has a North American origin or Asian origin. In this paper, I test these two hypotheses based on current fossil records and former phylogenetic analyses. Phylogenetic and fossil evidence, such as derived tyrannosaurine fossils of Asia, suggests that the hypothesis of an Asian origin of Tyrannosaurus rex is the most plausible one, but this is yet to be certain due to the scarcity of fossil records. INTRODUCTION The most famous and iconic dinosaur of all time, Tyrannosaurus rex, is only known from upper Maastrichtian geological formations in Western North America (e.g. Carr and Williamson, 2004; Larson, 2008). However, older relatives of Tyrannosaurus rex (e.g. Daspletosaurus, Tarbosaurus) are known from both Asia and North America. This leads to an evolutionary question: is the origin of Tyrannosaurus rex from Asia, or North America? About six of the currently valid tyrannosaurine taxa were described in the twenty-first century (based on parsimony analysis of Brusatte and Carr, 2016), with new species which are being described (Sebastian Dalman, Pers. Comm., 2016; Thomas Carr, Pers. Comm., 2016). It can be said that "now" is the "golden age” for studying tyrannosaurine evolution.

  • Caenagnathids of the Dinosaur Park Formation (Campanian) of Alberta, Canada: Anatomy, Osteo- Histology, Taxonomy, and Evolution Gregory F
    Vertebrate Anatomy Morphology Palaeontology 8:105–153 105 ISSN 2292-1389 Caenagnathids of the Dinosaur Park Formation (Campanian) of Alberta, Canada: anatomy, osteo- histology, taxonomy, and evolution Gregory F. Funston School of GeoSciences, University of Edinburgh, Edinburgh, Scotland, UK and Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada; [email protected] Abstract: Our understanding of caenagnathid anatomy, diversity, and ecology has improved considerably in the past twenty years, but numerous issues still remain. Among these, the diversity and taxonomy of caenag- nathids from the Dinosaur Park Formation of Alberta, Canada, have remained problematic. Whereas some authors recognize three genera, others suggest only two are present, and there is considerable disagreement about which specimens are referable to which genus. This study aims to resolve this issue by reviewing the known specimens and using osteohistology to establish a testable taxonomic framework of Dinosaur Park Formation caenagnathids. Numerous new specimens from all regions of the skeleton provide insight into morphological variation in caenagnathids, and three morphotypes are recognized based on a combination of morphological features and body size. Osteohistology shows that representatives in each body size class are at skeletal maturity, and therefore supports the delineation of three taxa: the smaller Citipes elegans gen. nov., the intermediate Chirostenotes pergracilis, and the larger Caenagnathus collinsi, new material of which shows it rivalled Anzu wyliei in size. However, these analyses also raise concerns about the referral of isolat- ed material to each taxon in the absence of skeletal overlap between specimens or osteohistological analysis. Caenagnathids are consistently recovered throughout the Dinosaur Park Formation interval, and two geo- graphic clusters of increased abundance probably reflect collection and taphonomic biases.
