This section was measured in the north of the Minzhuochaka Lake in the Nagri region. We collected and studied the fusulines, conodonts and smaller foraminifers from the Strata. The conodonts are dominated by Sweetognathus and Mesogondolella species. The fusulines are dominated by Neoschwagerina, Pseudodoliolina, Mesoschubertella. The smaller foraminifers consist mainly of Pachyphloia, Langella, Palaeotextularia and Tetrataxis. From the viewpoint of conodonts, their age is Kungurian. From the viewpoint of fusulines, it suggests a Murgabian age. The coexistence of fusulines and conodonts suggests that the upper Kungurian of International Scale correspond to the Murgabian of Tethyan Scale. This has provided robust evidence to support a correct correlation between the global scale and Tethyan scale of the Permian stage. In paleobiogeography, the present of conodonts and fusulines in the section suggests that the South Qiangtang Block was in a warm-water environment during the Kungurian time. By contrast, the Kungurian faunas in the Lhasa Block are dominated by cool-water taxa without any warm-water fusulines. The discovery of both conodonts and fusulines suggest a different paleobiogeography between the Lhasa and South Qiangtang blocks during the Kungurian time.

The establishment and improvement of the chronological framework of the Cenozoic strata within and around the Tibetan Plateau, are very essential and significant for revealing the history of the collision, uplift and deformation of the Tibetan Plateau. It's vital to enhance the understanding of the denudation and weathering patterns varying with time and space and find out the mechanism of the uplift and deformation of the Tibetan Plateau and its relevant effects on the regional and even global environment and climate. This data set has improved or established the chronological framework of the Cenozoic strata within and around the Tibetan Plateau, based on the magnetostratigraphy and accompanied by zircon U-Pb geochronology of the volcanics/tuffs/sedimentary tuffs or detrital rocks and/or biostratigraphy. The precisely dated sedimentary sequences include a 90-m loess sequence of the Duikang section constrained as ~8.1-3.7 Ma in the Linxia basin, several fluvial and lacustrine sequences (such as the 1890-m Dayu section with a range of ~41.8-21.5 Ma in age in the Lunpola basin, the 300-m Shuanghe section dated as ~42.7-36 Ma in the Jianchuan basin, the 252-m Caijiachong section with a range of ~47-36 Ma in the Qujing basin) and a 932-m saline lacustrine sequence with gypsolyte of the Jiangcheng section in the Simao basin whose age has identified to >112-63 Ma. All relevant experiments of the above chronology results have been conducted in the Institute of Tibetan Plateau Research, Chinese Academy Sciences, Lanzhou University, Tübingen University (Germany) , University of Texas at Austin (USA). The thermal demagnetization has been implemented using a thermal demagnetization oven and measured by a cryogenic magnetometer in a magnetically shielded room. The zircon U-Pb dating has been carried out using an inductively coupled plasma mass spectrometer with an attached laser ablation system. This data set provides an important chronological foundation for the following researches on tectonic evolution, paleoenvironment and paleoclimate. It has created a series of original theoretical achievements with widespread influence.

The Ediacaran to early Cambrian representing the transition of Cryptozoic to Phanerozoic is one of the most important transitional periods in the earth system evolution and a hot period for the study of the origin and evolution of metazoan. Focusing on this scientific question, massive interdisciplinary studies including palaeontology, stratigraphy, geochemistry, geophysics etc. have been taken in many regions which significantly improve our understandings of this period. In the Himalaya zone, the correlative strata only have been reported and studies in a few regions in the Sub Indian Continent. The North Pakistan locating the western Himalaya is one of the adjoining areas of Tibet Plateau. For the lack of basic stratigraphic and palaeontological studies, it’s hard to confirm the exact age of the Neoproterozoic to early Cambrian strata assigned by the previous studies. Thus, for the establishment of the chronological framework in western Himalaya, it’s necessary to do more detailed investigations and sample collections to sort out the sedimentary sequence, biostratigraphy and chemostratigraphy of this interval in North Pakistan. During the expeditions in the Hazara Basin, we detailedly observed the lithostratigraphy and systematically collected samples for petrological, palaeontological and geochemical studies at Sikhar Mountain, Tarnawai Village, Salhad Village, Abbottabad Height, Sobangali, Neelor Village and Pindkhan Khel sections. The result of this preliminary investigation confirmed that the Hazara Basin deposited a relatively successive Ediacaran to early Cambrian strata.

Ostracods from the Silurian Pulu Formation in the Yalai West II section, Nyalam (GPS coordinates: 28°24′3.52″N, 86°5′55.08″ E) and the Devonian–Carboniferous transitional interval in Xainza (GPS coordinates: 31°4′ 11″N, 88°41′08″E) are described for the first time. The methodology, known as ‘hot-acetolysis’, was used to extract ostracods from the limestones. About 1050 and 2460 specimens were obtained, including both single valves and carapaces from the Yalai west II section, Nyalam and Chaguoluoma DCB section, Xainza, respectively. In the Yalai West II section, thirty-two species belonging to 19 genera are identified and figured, and the ostracod fauna indicates an age of the late Llandovery Pridoli for the Pulu Formation. At the stratotype section of the Chaguoluoma Formation, Xainza, fifty-three ostracod species of 19 genera are identified and figured including a new species Bairdiacypris xainzaensis n. sp. The ostracod fauna in the Chaguoluoma section may represent an age close to the Devonian–Carboniferous boundary. New findings of ostracods fauna have great significance for biostratigraphy subdivision ad correlation. This dataset include identification lists from the Yalai West II and the Chaguoluoma sections.

Palaeozoic chronostratigraphic division and correlation are mainly based on biostratigraphy studies. Western Thailand was located in the Sibumasu terrane, having palaeogeographic affinity to the western Yunnan and Qiangtang terranes. Previous biostratigraphic sequences of major fossil groups have been poorly studied here. However, most of the paleontological work being conducted in western Thailand is of a reconnaissance nature. Collections and identifications of important index fossils are especially significant in improving our understating of Early Paleozoic stratigraphy in Sibumasu terrane, to correlate with Xizang and western Yunnan of China. Abundant fossil samples from the Tha Manao Formation in western Thailand (Sibumasu terrane, Dapingian Wat Mong Kratae section, GPS coordinates: 14°25′57″ N, 99°7′23″) were collected and identified in this study, including conodonts Drepanoistodus pitjanti, Erraticodon patu, Protopanderodus nogamii, and cephalopods Wutinoceras sp., Armenoceras sp., Wadema sp.. This collection suggests the Tha Manao Formation an age of upper Floian to middle Darriwilian of Middle Ordovician.

Paleozoic carbonate sequences are well developed along the road from the Leiwuqi County to the Jiangda County, Changdu, eastern Tibet. Preliminary Devonian-Carboniferous biostratigraphy studies based on macro-fauna (e.g. brachiopods and corals) have been conducted by previous researchers, but high-resolution subdivision and correlation is still lacking in study area. For example, Upper Devonian Zhuogedong Formation and Lower Carboniferous Wuqingna Formation exists near Tuoba and Wuqingna village. Abundant conodonts, rock and geochemical samples from the Nuoma section in Tuoba, Karuo District, Changdu have been collected, which was assigned to the Devonian-Carboniferous boundary interval by geological survey. Our studies would provide precise biostratigraphic correlation in this area and have important significance for redefinition of the DCB GSSP. This dataset includes the stratigraphic column and outcrop photo of the Nuoma section in Changdu (GPS coordinates: 97°49’53.06’’ E, 31°27’2.94’’ N). According to the conodont data, the Devonian-Carboniferous boundary is tentatively placed within the interval between 141 m to 188 m in this section.

This data is the relevant data of biogeochemistry and stable isotope geochemistry of Qaidam Basin. This set of data is mainly based on the research means of paleontology, sedimentary strata and biogeochemistry of typical sections to explore the sedimentary, climatic and biological response of Qaidam basin to the uplift of Qinghai Tibet Plateau in Cenozoic. The data of paleontological isotope and oxygen isotope of the Dachaigou basin are the main biomarkers for the study of Paleontology in the Dachaigou basin. The preliminary research processing results show that the data quality is high

The fossil records of large amphicyonids in Asia are rare and fragmentary, and their evolution and dispersal are also unclear. Here we present new dental material from Laogou, Linxia Basin, Gansu Province, belonging to the Hujialiang Formation, Middle Miocene. The new material is very similar to Amphicyon zhanxiangi from the Dingjia’ergou fauna of the Zhang’enbao Formation, Tongxin, Ningxia, and can be referred to this species. It is younger than the Tongxin material and differs from the latter by having better-distinguished cusps in upper molars, supporting this species is probably the ancestor to the omnivorous Arctamphicyon found in the Siwaliks, Yuanmou, and the Lower Irrawaddy. This lineage might immigrate to southern and southeastern Asia by the Late Miocene, and adapted to an increasing omnivorous diet due to more available plant material in tropical and subtropical regions.

The Late Paleozoic carbonate strata are well developed from Lewuqi County to Jiangda County in the Changdu area, eastern Xizang. The previous biostratigraphic studies based on macro-fossils (e.g. brachiopod and coral) are not sufficient for high resolution correlation. The seemingly continuous strata at Tuoba and Wuqingna have been divided as Zhuogedong Formation (or Qiangge Formation) of Late Devonian and Wuqingna Formation of Early Carboniferous mainly by lithology. We made detailed sampling for conodont, sedimentary and geochemical research at the outcrops between Tuoba and Wuqingna near Nuoma Village which according to the unpublished data belong to the Devonian-Carboniferous boundary interval. This study is significant for high resolution correlation of Late Devonian and Early Carboniferous in this region and the global stratotype study. The dataset only includes the stratigraphic column and photo of the section. The bio-chronological information will be added in the future.

The Qaidam Basin is a key area for understanding the paleoenvironmental and faunal history of the Tibetan Plateau. The fossil schizothoracine fish, Hsianwenia wui, evolved extraordinarily thickened bones to adapt to the aridification of the Qaidam Basin during the Pliocene. However, the nature of the bone thickening itself remains elusive. To promote the further investigation of the physiological mechanism of the pachyostosis and the phylogenetic interrelationships of Hsianwenia and all relevant cyprinids, here we present a comprehensive morphological study of Hsianwenia. We have new information on the anterior part of the cranial cavity, a large supraneural 3 in the Weberian apparatus, numerous procurrent caudal fin rays supported by the preural centrum (Pu) 5, and a neural arch on Pu2. We also find the differentiated pattern of the bone-thickening: the pachyostosis exists in the endoskeleton but not in the dermal skeleton; it is more obvious in ventral bones than in dorsal ones, when the thickening is present in the dorsally and ventrally grouped endoskeletal bones (e.g., the epineural and epipleural intermuscular bones). Considering the integrity of musculoskeletal system manipulating the chewing activities, we suspect that the thickened pharyngeal jaws and the hard food processing might be associated with the unique hind protrusion (cleithral “humeral” process) of the dermal pectoral girdle of Hsianwenia.

In March of 2019, scientists from Nanjing Institute of Geology and Palaeontology, CAS and Comsats University Islambad in Pakistan have a joint research in the stratigraphy in the Salt Range of Pakistan. The research goal is to reveal the Late Permian strata and faunas in the northern Tethys Himalaya region and their relationships with that of Southern Tibet. The investigated sections were done by rulers in the fieldwork and the foraminifer samples were sampled in high resolution. Totally, two sections were measured in the Zaluch Nala region, respectively Zluch Nala A and B sections. The foraminifers were cut and made into thin sections in the laboratory. All the foraminifers were identified in the microscope and form this dataset. The dataset contains the identification lists of fusulines and smaller foraminifers from the Zaluch A and B sections in Salt Range of Pakistan. The Permian strata in this region is well outcropped. It contains Amb, Wargal and Chhidru formations in ascending orders in the Zaluch Nala valley. The Amb Formation is dominated by calcareous limestone with only one fusuline Monodiexodina kattaensis. Its age is Middle Permian based on the fusuline. The Wargal Formation is dominated by middle and thin bedded limestone in the lower and nodular limestone in the upper. The Chhidru Formation is dominated by limestone and sandstone beds. The fusulines in the Wargal and Chhidru formations consists of Codonofusiella, Nankinella, Nanlingella and Reichelina with low diversity. The smaller foraminifers are dominated by Colaniella, Climacammina and Multidiscus. Those fusulines indicates a Late Permian age for the middle and upper part of the Wargal Formation and Chhidru Formation. The Salt Range region was located at northern margin of Gondwana during the Late Permian. So, in paleobiogeography, the diversity of foraminifers in the Middle and Late Permian strata in the Salt Range is lower that those in the Lhasa Block and exotic limestone blocks within the Yarlung Tsangpo Suture Zone in Tibet. But it is apparently greater that those in the Selong and Qubu regions in southern Tibet because the latter two regions is dominated purely by cold-water faunas without fusulines.

The research goal is to reveal the Late Permian strata and faunas in the northern Tethys Himalaya region and their relationships with that of Southern Tibet. The investigated sections were done by rulers in the fieldwork and the foraminifer samples were sampled in high resolution. Totally, two sections were measured in the Zaluch Nala region, respectively Zluch Nala A and B sections. Both sections are located at the northeast of Mianwali city in Salt Range, Pakistan. This section contains the strata of the Amb, Wargal and Chhidru formations. In the Zaluch Nala A section, the strata are composed of the upper part of the Wargal Formation (Kalabagh member) and the Chhidru Formation. The Zaluch Nala B section is structurally below the A section. The topmost part of the Zaluch Nala B section may probably correlate with the basal part of the Zaluch Nala A section. The Zaluch Nala B section is composed of lower part of the Wargal Formation and the Amb Formation. The Amb Formation is dominated by calcareous limestone. The only fusuline species Monodiexodina kattaensis indicates a Middle Permian age for this formation. The lower part of the Wargal Formation is dominated by middle and thin bedded limestone. The species of Pseudocolaniella occurs in the lower part of the Wargal Formation indicates a Late Permian age. The upper part of the Wargal Formation (in the A section) is dominated by nodular limestone, namely the Kalabagh member. The overlying Chhidru Formation is dominated by limestone and sandstone beds. The foraminifers from these formations consist of Reichelina, Codonofusiella and Reichelina. They suggest also a Late Permian age.

Southern Xizang represents a most important part of the Neo-Tethys. Neo-Tethyan deposits in this region can be divided into two types in general: a deep water oceanic represented by the Yarlung Zangbo suture zone and the other shallow marine one in the south of the suture. The main history of the Neo-Tethys is seen in the Triassic to Paleogene sequence, which destines the work of building a complete sedimentary sequence of the Neo-Tethys a basic goal of this scientific expedition. This dataset packages all the fossiliferous profiles that have been explored in the field by the Mesozoic and Cenozoic expedition group of the Nanjing Institute of Geology and Palaeontology of the Chinese Academy of Sciences on the Yarlung Zangbo suture zone and Tethys Himalayan Triassic to Paleogene in southern Xizang. There are 12 column profiles, compiled in an order of age from old to young.

The Qaidam Basin is located in the northern margin of Qinghai Tibet Plateau. It is one of the most representative sedimentary basins in Qinghai Tibet Plateau. Tertiary red sandstones, Jurassic coal stara and Cretaceous conglomerates are developed in the basin, The paleoclimate, paleogeography and paleotectonic information recorded in the study are of great significance to the study of the uplift and evolution of the Qinghai Tibet Plateau. The field stratigraphic investigation of Qaidam Basin is not only beneficial to the reconstruction of paleoclimate, paleogeography and paleostructure of Mesozoic terrestrial system, but also to the exploration, development and utilization of coal, oil and gas resources in Qinghai Tibet region. It is also beneficial to the scientific investigation of Qinghai Tibet region and is expected to contribute to the major national development strategy Make a contribution. This field exploration and sampling were finished in multiple sections in the Qaidam Basin, and details of the Mesozoic and Cenozoic strata in these sections and field photos were provided.

The Yarlung Zangbo suture zone and its neighbouring areas are key to the research of the evolution of Neo-Tethys. The sedimentary sequence as evidence of the evolution of Neo-Tethys remains unclear in many areas, particularly in the western and northern Xizang. The limits in stratigraphy and sedimentology have greatly restricted the investigation of the evolution of Neo-Tethys as well as the collision between Indian-Eurasian plates. This exploration team conducted a joint investigation on the Mesozoic strata in this area, with emphasis on their stratigraphy, palaeontology, and sedimentology, to retrieve potential stratigraphic and sedimentary evidence of the opening, evolution, and retreat of the Neo-Tethys. This dataset records the work of the expedition team in Xigaze, Ngari and Nagqu of Xizang. It consists of four parts, each part includes diaries and photos of the strata, geological structure, profiles, and fossils that have been collected by a special expedition group. The explored strata encompass the Cretaceous and Paleogene and the radiolarite strata in the above mentioned areas.

The North Pakistan locating the western Himalaya is one of the adjoining areas of Tibet Plateau. For the lack of basic stratigraphic and palaeontological studies, it’s hard to confirm the exact age of the Pre-Cambrian to Cambrian strata assigned by the previous studies. Thus, for the establishment of the chronological framework in western Himalaya, it’s necessary to do more detailed investigations and sample collections to sort out the sedimentary sequence, biostratigraphy and chemostratigraphy of this interval in North Pakistan. During the expeditions in the Hazara Basin divided into eastern (Abbottabad block) and western (Tanawal Block) segments across Panjal-Khairabad Thrust (PKT or MCT), we detailedly observed the lithostratigraphy and systematically collected samples for petrological, palaeontological and geochemical studies at the sections in both eastern (Sikhar Mountain, Tarnawai Village, Tanakki, Abbottabad Height and Sobangali sections) and western (Neelor Village and Pindkhan Khel sections) Hazara Basin. Basing on the lab analysis, we have detailed correlated and sorted the lithostratigraphic sequences of each section, and completed a correlative lithostratigraphic columns of the sections. In general, the lithology of these sections in eastern and western Hazara Basin are comparable and consist of the Hazara Formation (Eastern Harara Basin) and Tanawa Formation (Western Harara Basin), Ediacaran Tanakki Diamictite, Cap-Carbonate, Kakul Formation (siliciclastics) and Abbottabad Formation (dolostone)、Cambrian Hazira Formation (phosphorite, dolostone and siliciclastics ) and Jurassic Samana Suk (bioclastic limestone) in ascending order. The Tanakki Diamictite disconformably overlies the underlying Hazara Formation (Eastern Harara Basin) and Tanawa Formation (Western Harara Basin); the Abbottabad Formation both disconformably contacts with the under Kakul Formation and upper Hazira Formation; the Jurassic Samana Suk directly unconformably overlies the Cambrian Hazira Formation. For now, the Ediacaran Cap-carbonate has only been observed at the Pindkhand Khel section in the western Hazara Basin which is reported in the Lesser Himalaya for the first time. Thus, it is possible to induce the underlying Tanakki Diamictite is belong to Ediacaran in age. However, the exact Cambrian Hazira Formation bearing abundant small shelly fossils has only been confirmed at Tarnawai Village and Tanakki sections in eastern Harara Basin.

The occurrence and diversification of the skeletal fossils during the latest Ediacaran and early Cambrian (Terreneuvian) witness the significant evolutionary event, “Cambrian explosion”, in earth history. These skeletal fossils were collectively termed as “small shelly fossils (SSFs)” for their micro-size and mineralization in normal. They represent the earliest metazoan records, and are crucial for studying the origins and early evolution of many animal clades. Due to their worldwide distribution and rapid biodiversification, the SSFs have been taken as an important tool for the early Cambrian stratigraphical correlation (especially for the Terreneuvian) and paleobiogeographical reconstruction. The North Pakistan locating the western Himalaya is one of the adjoining areas of Tibet Plateau. For the lack of basic stratigraphic and palaeontological studies, it’s hard to confirm the exact age of the Neoproterozoic to early Cambrian strata assigned by the previous studies. Few SSFs had been reported in the early Cambrian Hazira Formation at Salhad section in the eastern Hazara Basin, however, the studies of these fossils are quite preliminary and problematic. Therefore, it’s urgent to carry on new detailed research to clarify the genus and species of these fossils which is fundamental for the biostratigraphical studies. Herein, basing on the expedition of the Salhad section in eastern Hazara Basin, we have systematically collected and done the lab process of the fossil samples, and tentatively recognized 24 genus, 18 species and 3 unidentified species.

Paleozoic strata are well developed and widely outcropped around the Xainza area of central Tibet. Among them, the Devonian succession was first introduced during the geological survey in the late 1970s, and was suggested to comprise the Middle Devonian Dardong Group (including the Lower and Upper formations) and the Upper Devonian Chaguoluoma Formation. However, high-resolution stratigraphic framework and palaeontological research are still lacking for the Lower Devonian in study area. This investigation focus on the Dardong Formation in this area, and detailed geological survey and detailed sampling were carried out in order to improve stratigraphic correlation in central Tibet. The Dardong Formation mainly consists of carbonate and siliciclastic sediments, yielding abundant fossils such as brachiopods, corals, cephalopods, conodonts, tentaculites, etc. The Xainza II section is exposed along the cliff of a mountain. The studied Dardong Formation can be divided into five lithological units in ascending order: 1) light grey to grey medium- to thick-bedded limestone with cross-bedding in the middle part, yielding fragments of brachiopods and crinoid stems; 2) grayish white thin- to medium- bedded siltstone; 3) light grey to grey thin- to medium-bedded limestone, containing colonial corals and crinoid stems; 4) grey medium- to thick-bedded limestone; 5) light grey medium-bedded limestone with fragments of crinoid stems, partially covered in the upper part. This dataset includes the stratigraphic column of the SZ2 section and outcrop photos in the Xainza area, central Tibet.

The Nyalam region of southern Tibet, China, is one of the best locations to study Wenlock to Pridoli conodonts in China, due to the relatively continuous strata. The Yalai West II section is located on the mountain west of the Yalai Town. The Pulu Formation is composed of bioclastic wackestones with some interbeds of lim-mudstones, packstones and calcisiltites. Abundant cephalopods and conodonts, as well as rare bivalves and corals were reported from the Pulu Formation. The Pulu Formation represents a shallow-water marine environment with slow depositional rates. Five conodont biozones are established, i.e., the Ozarkodina sagitta sagitta Biozone, the Kockelella crassa Biozone, the Kockelella variabilis variabilis Interaval Biozone, the Polygnathoides siluricus Biozone, and the “Ozarkodina” eosteinhornensis s.l. Interval Biozone from the Homerian of Wenlock to Pridoli are recognized from the Pulu Formation, which is assigned to the late Telychian of Llandovery to Pridoli based on the conodonts, as well as the graptolites from the underlying strata. Among the conodont fauna in the Nyalam region, Wurmiella alternata has only been recognized from the Gondwana and peri-Gondwana, but others are widespread, which might be an indication of the cosmopolitan character of the Wenlock to Pridoli conodonts.

In southern Tibet, Paleozoic strata are well developed and widely outcropped in the Himalaya area. The early stratigraphical divisions and palaeontological investigations of the Mt. Jolmo Lungma area were conducted by pioneer expedition teams in the 1920s, which originally assigned a Carboniferous or Permian age to the limestone from the Summit. The discovery of Ordovician strata in the region was mainly based on finding of index fossils from the Jiacun and other sections in the vicinity of Mt. Jolmo Lungma. However, detailed palaeontological research is still lacking for the Late Ordovician in study area. Our research focus on ostracods fauna from the Jiaqu Formation, which are described for the first time from the Upper Ordovician in Nyalam, southern Xizang (Tibet). Thirty species belonging to sixteen genera are described and figured from the Yalai Waterworks section. The ostracod fauna suggests a probable Sandbian-Katian age for the Jiaqu Formation. The ecological assemblage of ostracods fauna belongs to the Eifelian Ecotype, which implies deposition in an environment of nearshore when the Jiaqu Formation was being laid down. Many cosmopolitan or provincial genera were present in diversified ostracod fauna of the Jiaqu Formation, suggesting close biogeographic relationships among Himalaya terranes, Tarim and South China plates. This dataset includes the stratigraphic column of the Jiaqu Formation section and outcrop photos in the Himalaya area, southern Tibet.

Paleozoic chronostratigraphic division and correlation are mainly based on biostratigraphy studies. In Tibet, biostratigraphic sequences of major fossil groups, such as conodont and rugose coral, have been briefly summarized by previous research. However, due to its remoteness, high altitude and the geographic extent of this vast mountainous region, most of the paleontological work being conducted in Tibet is of a reconnaissance nature. Collections and identifications of important index fossils are especially significant in improving our understating of Paleozoic stratigraphy in Himalayan, Lhasa and Qiangtang terranes and associated arc-basin systems. Abundant conodont, rugose coral, tabulate coral and stromatoporoid samples from the Pulu Formation in Nyalam (Himalaya terrane, Llandovery to Pridoli Yalai 2 sction, GPS coordinates: 28°24′17″ N, 86°5′48″ E）) and the Dardong Formation in Xainza (Lhasa terrane, Pragian to early Emsian SZ1 and SZ2 sections, GPS coordinates: 31°8′36.63″ N, 88°38′39.22″ E和31°7′56″ N, 88°37′47″ E), Tibet and the Changtanzi Formation in Longmenshan (Songpan-Ganzi terrane, Late Devonian Famennian Longmenshan section, GPS coordinates: 31°54′3.55″ N, 104°42′29.82″ E), Sichuan were collected and identified in this study.

Carbon cycle is controlled by relative changes in carbon fluxes of global atmosphere, hydrosphere, lithosphere, and biosphere. During the geological history, carbon isotope excursions usually occur in the critical period. Carbon isotope positive excursions are recognized to be related to abundant organic burial or enhanced primary productivity. Silurian δ13Ccarb curves from Euramerica have been established, but the isotopic patterns in different sections and regions can be quite different. Before the use of δ13Ccarb records to facilitate high resolution correlation, it is necessary to conduct sedimentary facies and diagenesis analyses and compare numerous isotopic records on a global scale, in order to learn the global versus local contribution in a δ13C record. 43 geochemical samples were collected from the Wenlock to Pridoli Pulu Formation for carbon and oxygen isotopic analyses, in order to reveal carbon cycling process in northern margin of Gondwana continent and alternation of carbon isotopic records during diagenesis. At the Yalai 2 section, δ13C values show a major positive shift in the Ludlow, which could be recognized in other sections around the world, indicating that major carbon cycling perturbation occurred during this time interval. This dataset include 43 carbon and oxygen isotopic records.

Sinothemis difficilis new genus new species, youngest and first accurate Chinese representative of the small family Selenothemistidae, is described and illustrated. It is closely related to the genus Turanothemis, known from the Karatau outcrop in Kazakhstan. The genus Caraphlebia, known from the Middle Jurassic of Antarctica, seems to strongly differ from the other representatives of this family and may belong to another family. The fossil was collected from the Upper Jurassic (157.3 ± 1.5 Ma; near Oxfordian/Kimmeridgian boundary) Guancaishan locality, Jianping County, Western Liaoning, NE China. It belongs to the late assemblage of the Yanliao biota, while the early assemblage is represented by the putatively close damsel-dragonfly Paraliassophlebia from the Jiulongshan Formation of northern Hebei Province

Stomatal parameters of fossil plants include stomatal density and stomatal index. Stomatal density is the number of stomata per unit area, usually expressed as the number of stomata per square millimeter leaf area. Stomatal index is the percentage of stomatal number to the total number of stomatal and epidermal cells. The cuticle with stomata is located at the interface between plant and atmosphere, which contains important data about the relationship between plant and living environment. Moreover, the new technology of cuticle analysis can make many plant leaf fossils become valuable paleo atmospheric environment database. This data comes from my team and other published papers. I will make statistics, screen and upload the stomatal parameter data in these published papers. At present, stomatal parameters are widely used, such as: using stomatal parameters to calculate paleoatmospheric CO² concentration, using stomatal parameters to reconstruct paleo sea level, etc.

The most primitive Elasmotherium (Perissodactyla, Rhinocerotidae) from the Late Miocene of northern China, The origin of Elasmotherium has been a puzzle for many years. Herein, we report the earliest representative of Elasmotherium, based on a Late Miocene skull from Dingbian County in Shaanxi, northwestern China. The skull bears a unique mosaic of primitive and derived features different from all hitherto known elasmotheres, hence forth demarcated as holotype of Elasmotherium primigenium sp. nov. Dental characters of E. primigenium are more primitive than any other known species of lasmotherium, e.g. relatively incipient enamel folding, fairly weak lingual groove on the base of the protocone, relatively weaker crista, small and closed posterior valley and straight ectoloph. E. primigenium is evidently more primitive than all the known species of Elasmotherium, yet appreciably more derived than Sinotherium, thereby marking an important transitional species between Sinotherium and further species of the genus Elasmotherium.

The Yarlung Zangbo suture zone and its neighbouring areas are crucial for the research of the evolution of Neo-Tethys. The earliest evidence of the formation of Neo-Tethys remains to be discovered and the sequence of the basin evolution in many areas, such as the eastern and western Xizang, is far from well established. The limits in stratigraphy and sedimentology have greatly restricted the investigation of the evolution of Neo-Tethys as well as the collision between Indian-Eurasian plates. This exploration team conducted a joint investigation on the Mesozoic strata in some key areas in eastern, central, and southern Xizang, with emphasis on their stratigraphy, palaeontology, and sedimentology, to retrieve potential stratigraphic and sedimentary evidence of the opening, evolution, and retreat of the Neo-Tethys in the region. This dataset is a collection of the exploration, which includes diaries and photos of the strata, geological structure, profiles, and fossils that have been collected in the above-mentioned areas. It consists of three items. The explored strata include the Jurassic-Cretaceous in Luolong and Basu counties, eastern Xizang, in Renbu and Lang counties, central Xizang, and the radiolarite strata in Ngari.

With a depositional history spanning the early Aptian to early Albian (~19 mys), the Lower Cretaceous Xinminpu Group in Jiuquan, NW China provides abundant animal and plant fossils. This area is the represented study area of the Lower Cretaceous in China. The absence of a comprehensive stratigraphical framework for this area however limits the degree to which the unit can be interpreted relative to coeval sections and the geological records in genera. This investigation from July 9 to July 11 focuses on the Lower Cretaceous in this area, and collected abundant fossil and rock samples for biostratigraphic and stratigraphic analysis. This dataset includes: stratigraphic column of the Chijinpu Formation in the East Xiagou outcrop, and photographs of outcrops and represented fossils; stratigraphic column of the Xiagou Formation in the Changma outcrop and a photo of bird-bearing outcrop.
