Summary: This study reports and describes a chancelloriid fauna for the first time, which exhibits taxonomic composition similar to other Cambrian species in different regions. Based on the construction of sclerites, different articulatory facet types can be used to distinguish between chancelloriid species, and the number of rays is closely related to the arrangement of sclerite rays. This study is significant for understanding the diversity of chancelloriid fauna in the middle Cambrian platform of the Precordillera.

Summary: The study reveals that alluvial fans in the western piedmont of the Argentine Precordillera developed during the Early-Middle Pleistocene and were influenced by Quaternary-active structures and climate. The alluvial fan systems typically became inactive at the beginning of or during interglacial periods. The El Tigre Fault has tectonically controlled the fluvial network since the Middle-Pleistocene.

Summary: This study critically reviews the chronostratigraphy and biostratigraphy of the latest Carboniferous and Permian in the North China Block and provides insights into the stratigraphic correlation and geological events. The study also estimates the amplitude of sea-level changes and highlights the favorable period for coal accumulation during the late Carboniferous and early Permian. The climatic shift during the Permian is attributed to the northward migration of the Pangea and the closure of the Paleo Asian Ocean.

Summary: This study focuses on the late Eocene Yaw Formation in central Myanmar and investigates the past vegetation, climate, and depositional environments. The results reveal that the Eocene Burmese deltaic plains were dominated by lowland evergreen forests and swamps, while terra firma areas were occupied by seasonally evergreen, seasonally dry, and deciduous forests, similar to the vegetation distribution around the Bay of Bengal today. The bioclimatic analysis indicates that the Yaw Formation in the late Eocene was more seasonal, drier, and cooler compared to the modern-day climate at a similar near-equatorial latitude. The high diversity of the Yaw Formation palynoflora suggests its role as a crossroads for plant dispersals between India and Asia.

Summary: Conodont fossils from the Indert Formation in southwestern Mongolia were studied to improve correlation of the uppermost Devonian-lowermost Carboniferous. The conodont fauna was found to be low in abundance and diversity, but representative species were collected from the Indert-Uul section. Five conodont biozones were recognized from the top Heermorit Member and lower part of the Shombon Member, while the middle and upper parts of the Shombon Member could not be characterized based on conodonts. The absence of index fossils hindered precise recognition of the Devonian-Carboniferous boundary, but it was well established by typical conodont assemblages.

Summary: This study conducted sedimentological and palynostratigraphic research on the Tera Group in the West Cameros Basin. The results show significant changes in sedimentary facies and palynological assemblages during the Jurassic-Cretaceous boundary transition, and suggest that the Jaramillo Formation belongs to the lower Berriasian.

Summary: This study elucidates the microfloral records of the Ganmachidam Formation in Spiti Valley, Tethyan Himalaya. The recovered palynomorphs suggest that the Ganmachidam Formation is late Pennsylvanian to early Permian in age and provide evidence that glossopterids might have originated in the Carboniferous period.

Summary: This study establishes five conodont zones for the Taiyuan Formation in southern North China and determines a late Gzhelian to late Asselian age, which is consistent with high-precision zircon U-Pb ages. The study also combines conodont biostratigraphy with previously published U-Pb ages to construct a new chronostratigraphic framework for the Carboniferous-Permian strata across North China. It reveals an earlier initiation of climate aridification in the northern part compared to the southern part, possibly due to northward drift, increased atmospheric pCO2, and global warming.

Summary: A 66 cm thick volcanic ash fall tuff with a paleobotanical fossil lagerstatte has been dated to 298.34 +/- 0.09 Ma in the Wuda coal district of North China. This finding provides a well-defined position of the Carboniferous-Permian boundary near the northern edge of the North China Block and suggests a revision of the age of the Taiyuan Formation in the northern part of the block.

Summary: This study provides a detailed analysis of the Carboniferous strata in Xinjiang, China, focusing on lithofacies associations and biotic assemblages. By analyzing geochronologic data from volcanic rocks and ash layers, a refined stratigraphic framework for the Carboniferous successions in Xinjiang is obtained. This research is important for regional and global stratigraphic correlations, as well as for understanding the tectonic evolution and petroleum exploration in Central Asia.

Summary: The foundational role of health information exchanges (HIEs) is to facilitate real-time communication between clinical partners. In addition to this role, HIEs can contribute to community public health and clinical care in various ways that align with their mission, goals, patient privacy, and funding structures. We support the development of community-integrated HIEs and provide specific steps that can be taken towards community integration. Three examples from a community HIE in El Paso, TX demonstrate the successful application of these steps, resulting in informatics tools to address community health needs and generate long-term benefits, particularly for vulnerable patients.

Summary: Knowledge of pre-Carboniferous strata development in the subsurface of the Netherlands is limited, leading to informal lithostratigraphic nomenclature for this time interval. A palynological study of core material from two wells in the southwestern Netherlands provided new insights into the regional stratigraphic development of pre-Carboniferous strata in the area.
