| 4 | A New Giant Compsognathid Dinosaur with Long Filamentous Integuments from Lower Cretaceous of Northeastern China显示文摘A new compsognathid dinosaur, Sinocalliopteryx gigas gen. et sp. nov., is erected based on a complete skeleton from the Early Cretaceous Yixian Formation of western Liaoning, northeastern China. It shares the features with Huaxiagnathus orientalis in having a manus as long as the humerus plus radius, very large and subequally long manual claws I and II, and reduced olecranon process on the ulna. But it differs from Huaxiagnathus orientalis in having the much large size, a very long maxillary process of premaxilla not extending the vertical level of the maxillary antorbital fossa, and the proportionally longer ulna and so on. Sinocalliopteryx gigas gen. et sp. nov. represents the largest species among the known compsognathid dinosaurs, suggesting the tendency of the body enlargement in compsognathids to some extent. The long filamentous integuments are attached to the whole body of this compsognathid, confirming that such integuments evolved firstly in the basal coelurosaurs. This new giant compsognathid was a fierce carnivorous theropod, as shown further by an incomplete dromaeosaurid leg inside its abdominal cavity. | JI Shu' an JI Qiang LU Junchang YUAN Chongxi | 2007 | Acta Geologica Sinica(English Edition)2007，81，1： | 7 |
| 5 | Largest Toothed Pterosaur Skull from the Early Cretaceous Yixian Formation of Western Liaoning, China, with Comments on the Family Boreopteridae显示文摘A new pterosaur Moganopterus zhuiana gen. et sp. nov. is erected based on a complete skull with lower jaws and anterior cervical vertebrae. It is characterized by much elongated upper and lower jaws with at least 62 total, long, curved teeth with sharp tips, a well developed parietal crest extending posterodorsally, forming an angle of 15 degrees with the ventral margin of the skull, the ratio of length to width of cervical vertebrae greater than 5:1. The skull length is 750 mm, and it is the largest toothed pterosaur found so far in the world. Based on this new pterosaur, the Boreopteridae can be divided into two subgroups: Boreopterinae sub-fam. nov. and Moganopterinae sub-fam. nov., which is also confirmed by the phylogenetic analysis. | LU Junchang PU Hanyong XU Li WU Yanhua WEI Xuefang | 2012 | Acta Geologica Sinica(English Edition)2012，86，2： | 6 |
| 6 | On the Systematic Position of Eosipterus yangi Ji et Ji,1997 among Pterodactyloids显示文摘A comparison of the new specimen with the holotype of Eosipterus from western Liaoning Province indicates that Eosipterus is a valid genus,which belongs to the family Ctenochasmatidae.The revised diagnosis of Eosipterus includes the wing span is less than 1.25 meters,the length of the ulna is nearly equal to these of wing phalanx 2 and the tibia,humerus is longer than tibia,and the ratio of metatarsal to tibia is approximately 0.40. | LU Junchang GAO Chunling MENG Qingjin LIU Jinyuan JI Qiang | 2006 | Acta Geologica Sinica(English Edition)2006，80，5： | 4 |
| 7 | A new pterosaur (Pterosauria) from Middle Jurassic Tiaojishan Formation of western Liaoning,China显示文摘A new pterosaur Archaeoistiodactylus linglongtaensis gen. et sp. nov. is erected based on an incomplete skeleton with a partial skull and lower jaw. The new taxon is characterized by circular tooth sockets of anterior mandibular teeth,the anterior teeth of the upper jaw bearing posteriorly directed crowns,a relatively short metacarpus,and wing phalanges 2 and 3 and the tibia subequal in length. It possesses some plesiomorphic characters such as short metacarpals and circular tooth sockets. The pointed jaw tip present in the new taxon indicates that the expanded jaw tips of later istiodactylids are a derived character state,and the new taxon represents the first istiodactylus-like pterosaur found from the pre-Late Jurassic deposits,which provides a key role in our understanding the origin and evolution of the known istiodactylid pterosaurs. Archaeoistiodactylus is regarded as the ancestor form of the known istiodactylid pterosaur. | LU Junchang FUCHA Xiaohui | 2010 | Global Geology2010，13，3： | 4 |

| 11 | SEM Observation of the Wing Membrane of Beipiaopterus chenianus (Pterosauria)显示文摘The cross-section and surface structures of wing membranes from the ctenochasmatid pterosaur Beipiaopterus chenianus were observed through a scanning electron microscope (SEM). The results show that the wing membrane contains a high density of blood vessels, implying strong thermoregulatory function, similar to that of a bat wing membrane. This is the first comparison of the microstructures of pterosaur wing membranes with those of the modern bat. It is inferred that a bat-like physiology exists, at least in relatively small pterosaurs suggesting that these pterosaurs were warm-blooded, active fliers. | LU Junchang KOBAYASHI Yoshitsugu YUAN Chongxi JI Shu'an JI Qiang | 2005 | Acta Geologica Sinica(English Edition)2005，79，6： | 2 |

| 13 | A New Pterodactyloid Pterosaur from the Early Cretaceous of the Western Part of Liaoning Province, Northeastern China显示文摘Pangupterus liui gen. et sp. nov. from the Jiufotang Formation of Sihedang, Lingyuan City, Liaoning Province is erected based on a nearly complete lower jaw. It is characterized by having a total of 36 slender curved teeth with sharp tips, forming a distinct fish-grabbing mechanism; the teeth are well-spaced and are circular in section; the length ratio of the mandibular symphysis to the whole jaw is 20%; and the ratio of the tooth root width to tooth length is 12%. Toothed pterosaurs make up about 56.3% of the pterosaur assemblage from the Jiufotang Formation, which indicates that toothed forms played a key role in the ecosystem. | LU Junchang LIU Cunyu PAN Lijun SHEN Caizhi | 2016 | Acta Geologica Sinica(English Edition)2016，90，3： | 1 |
| 14 | Statistical Approach for Classification of Dinosaur Eggs from the Heyuan Basin at the Northeast of Guangdong Province显示文摘The Zhutian and Dafeng formations(Upper Cretaceous) of the Heyuan Basin in northeastern Guangdong Province,China,have produced thousands of dinosaur eggs.Macromorphological features(egg diameter,egg shape,outer surface texture,and shell thickness) of 461 eggs were analyzed using non-destructive techniques and subjected to statistical analyses in order to assess their diversity and taxonomic affinities.Three types(1,2 and 3) of eggs were discerned based on shape and outer surface morphology.Type 1 eggs are spherical to ellipsoidal in shape and have a rough surface.Three subtypes(Type 1-A-1,1-A-2,and 1-B) are apparent from scatter plots and cluster analyses of egg diameters and shell thickness.Type 2 eggs are elongate with linear ornamentation on the surface,and are comparable to eggs that belong to the oofamily Elongatoolithidae.Type 3 eggs are elongate with a smooth surface,and are assigned to the oofamily Prismatoolithidae.Macromorphological features of the various egg types suggest that Type 1 could have been laid by ornithischian,sauropod or therizinosaur dinosaurs,Type 2 by oviraptorids,and Type 3 by troodontids.This study represents the first comprehensive statistical analysis of macrofeatures of dinosaur eggs,and reveals taxonomic diversity in the dinosaurs that were laying eggs in the Upper Cretaceous Heyuan area heretofore unrecognized in skeletal remains. | Kohei TANAKA LU Junchang LIU Yi HUANG Zhiqing Yoshitsugu KOBAYASHI HUANG Dong Darla K.

| 15 | A New Species of Huaxiapterus (Pterosauria:Tapejaridae) from the Early Cretaceous of Western Liaoning,China显示文摘A new species of Huaxiapterus:H.benxiensis sp.nov.is erected based on the new specimen. The diagnostic characters of Huaxiapterus benxiensis are well-developed premaxillary crest and parietal spine,the crest and spine parallel and extending posterodorsally,and a shallow groove present on the dorsal surface of the anterior portion of the mandibular symphysis.The different skull morphologies of Chinese tapejarid pterosaurs indicate that they are much more diverse than the previous thought. | LU Junchang GAO Yubo XING Lida LI Zhixin JI Qiang | 2007 | Acta Geologica Sinica(English Edition)2007，81，5： | 1 |
| 16 | A Preliminary Study on the Red Beds in the Northern Heyuan Basin, Guangdong Province, China显示文摘The red beds of the northern Heyuan Basin (Guangdong Province, China) are more than 4,000 m thick. Based on the lithological characters, in ascending order these beds are divided into the Dafeng Formation, Zhutian Formation, and Zhenshui Formation of the Nanxiong Group, Shanghu Formation and Danxia Formation. The Nanxiong Group with relatively mature coarse clastic rocks attains about 2,940 m in thickness. The Dafeng Formation is 837 m thick, consisting of conglomerates and sandy conglomerates; the Zhutian Formation, which is 1,200 m thick, consists of purplish red sandstone with gravels, poorly sorted sandstone, feldspathic quartzose sandstone banded granular conglomerate, siltstone, and sandy mudstone. The Zhutian Formation is rich in calcareous concretions. Heyuannia (Oviraptoridae) and turtle fossils were found in this formation. The Zhenshui Formation deposited to a thickness of 900 m consists of coarse sediments, including granular conglomerate, and gravelly sandstone with well developed cross-beddings; the Shanghu Formation, which is 820 m thick, consists of purplish red granular conglomerate coarse sandstone intercalated with fine siltstone; the Danxia Formation characterized by the Danxia landform is composed of coarse clastic gravels and sandy gravels. The lower part of the Nanxiong Group whence dinosaur eggs and derived oviraptorosaurs come, belongs to the Late Cretaceous. No fossils are found in the Shanghu Formation or the Danxia Formation, but their stratigraphic order of superposition on the Nanxiong Group clearly shows their younger age. | ZHANG Xianqiu LU Junchang BIAN Geguo QIU Licheng HUANG Dong YUAN Weiqiang | 2005 | Acta Geologica Sinica(English Edition)2005，79，5： | 1 |

| 18 | Influences of the tank liquid lateral sloshing and mass time-varying on high clearance self-propelled sprayer ride comfort显示文摘To explore the influence of the lateral sloshing and the time-varying mass of the liquid in the tank on the ride comfort of the high-clearance sprayer,a spring-mass-damping equivalent mechanics that can describe the lateral sloshing of the liquid under different filling ratios was constructed based on the equivalent criterion.The Fluent was used to simulate the moment acting on the wall of the tank by the lateral sloshing of the liquid,and then the parameters of the equivalent mechanical model are obtained by fitting and solving.Comparative analysis of Fluent simulation and bench test on lateral sloshing of tank liquid under different filling ratios.The results show that the lateral sloshing trend of the tank liquid level obtained from the Fluent simulation and the bench test was consistent,which proved the accuracy of the Fluent fluid simulation process and the correctness of the required equivalent mechanical model parameters.Incorporating a liquid sloshing equivalent model,a four-degree-of-freedom vertical dynamic model of the sprayer half-car was established.Subsequently,the performance of the sprayer was systematically analyzed and compared under the excitation of a bump road and a random E-level road.This investigation took into account varying liquid filling ratios of 10%,50%,and 90%.The focus lay on evaluating the vertical acceleration of the sprayer body,dynamic deflection of the suspension,and dynamic load on the tires in response to these road conditions.This analysis is conducted independently of the liquid sloshing factor.The results show that the lateral sloshing of the liquid medicine significantly reduces the ride smoothness of the machine,and makes the vibration response of the machine produce a certain hysteresis effect.With the reduction of the quality of the liquid medicine in the spray tank,the vibration amplitude of the sprayer body gradually decreases,the hysteresis effect is also gradually weakened.The results presented in this study offer a theoretical foundation for the analysis of ride comfort and the optimization of chassis structure in high-clearance sprayers. | Liquan Lu Junchang Zhang Cui Cui Jun Chen Yu Chen Hongling Jing Shuo Zhang Sugirbay Adilet Chenwei Hu Jiayu Cao | 2024 | International Journal of Agricultural and Biological Engineering2024，17，1： | 0 |
