Summary: Geodiversity refers to the variety of abiotic elements and processes present at different scales and dimensions in an area. This study quantified and assessed geodiversity in the Marrecas River drainage basin in southern Brazil, finding lower geodiversity in certain interfluves and estuary areas, and higher geodiversity in valleys. The results highlight the importance of not solely focusing on the richness of geodiversity, but also considering the spatial distribution of environmental components in the study area.

Summary: The timing of the final welding of the southern Altaids to construct Pangea is uncertain, leading to debate about the configuration of northeast Pangea and the reconstruction of proto-Asia. Analysis of sediments in a fore-arc accretionary basin in the South Tianshan Orogenic Belt reveals that they have a maximum depositional age in the early Triassic and originate from the distal East Tianshan Arc region.

Summary: The study found that a significant amount of microplastics can be found in surface waters and sediments in the Tibetan Plateau, mainly in the form of fibers ranging from 100 to 500 micrometers. The concentration of microplastics in the downstream of the Brahmaputra River nearly doubled compared to the upstream, largely due to human activities downstream.

Summary: Microplastics are widely present in the environment, with fibers being the most common shape and polypropylene being the most abundant type. The study found that microplastic concentrations were higher in salty water than in fresh water, indicating that salt intrusion accelerates microplastic fragmentation. Urban agglomeration and interception associated with sedimentation and precipitation were identified as major factors contributing to increased microplastic concentrations in downstream areas, with the highest levels observed around the Yichang City in the Yangtze River watershed.

Summary: Chitons are important bioeroders in present-day shallow seas, with evidence of their feeding preserved in the form of radular traces on invertebrate shells and hardgrounds. A recent study reports widespread grazing traces on the extinct sirenian Metaxytherium subapenninum, suggesting that bone has served as a substrate for chiton feeding for over 66 million years. The role of bioerosion in fossilization is significant, and further research on how grazing organisms contribute to the processes affecting bone can provide new insights into marine vertebrate fossilization.

Summary: This study investigates the provenance of the southeast Ordos Basin using petrology, sedimentology, subsidence and geochronology. The results show a shift in provenance from recycled orogenic to a mixture of recycled orogenic and arc magmatic materials. Tectonic subsidence and zircon age distribution suggest a transition from short and rapid uplift to remote continuous uplift. This study provides new insights into the closure process of the Mianlue Ocean during the Triassic and its impact on the tectonic environment of the southern North China Craton.

Summary: The Permian-Triassic Mass Extinction event had a significant impact on life in India, leading to the destruction of glossopterids and the replacement by stress-tolerant lycopsids. The discovery of an acritarch spike in the Indian subcontinent from the uppermost Permian to Lower Triassic sequence sheds light on the relationship between acritarchs and floral shifts, suggesting deposition under shallow marine conditions. Additionally, the presence of marine and hypersaline biomarkers indicates a possible marine incursion in the P-G basin during the extinction event.

Summary: This study presents sedimentological and taphonomic evidence to support the hypothesis of drought-induced mass death of tetrapods in the earliest Triassic strata of the southern Karoo Basin. The analysis of in-situ fossils reveals the presence of numerous articulated Lystrosaurus skeletons, suggesting that they died during periods of drought and starvation. The study also provides insights into the environmental conditions and evolutionary impact of these episodes of mass death.

Summary: The Middle-Upper Triassic Aghdarband Basin in NE Iran is characterized by a strongly deformed stratigraphic succession deposited in a complex tectonic setting related to a back-arc environment. The sedimentological and palynological analyses reveal a shift from xerophytic to hygrophytic vegetation, indicating a change in paleoclimate conditions. The unconformity between the Miankuhi and Sina formations is interpreted as a result of sea-level fall associated with humid climate shift during the Eo-Cimmerian Orogeny.

Summary: The paleoecology of Araripemys barretoi, a pelomedusoid turtle from the Lower Cretaceous of Brazil, was investigated. Analysis of forelimb proportions suggests that Araripemys barretoi had specialized morphology as an agile swimmer in large water bodies. Various postcranial anatomical features indicate that this species was adapted to different aquatic environments. Araripemys barretoi was abundant during the Aptian in the Araripe and Parnaiba basins, which were once an epicontinental sea related to the Equatorial Atlantic opening.

Summary: Late Pleistocene fossils from southern Brazil provide a unique opportunity to study the diet and habitat use of the extant franciscana dolphin (Pontoporia blainvillei) prior to human influence. Stable carbon and oxygen isotope analysis conducted on fossil and contemporary specimens reveal differences in isotopic composition, with fossils showing more disparate delta C-13 values and recent samples showing more disparate delta O-18 values. The differences can be attributed to impoverished modern fish communities and temporal changes in freshwater influx.

Summary: This article demonstrates the impact of the Parnaiba River Lineament on the tectonics of the Parnaiba Basin through the discovery of a paleontological finding from the Cretaceous period near a Permian sequence. A normal fault in the NNE-SSW direction caused the subsidence of the Cretaceous Itapecuru Formation and the relative uplift of the Permian Pedra de Fogo Formation. The presence of a Mesozoic theropod tooth at the same level as a Paleozoic unit provides evidence of tectonic activity affecting the stratigraphic successions of the Parnaiba Basin.

Summary: Through sediment records from Lake Nanyi in the lower Yangtze, we found that anthropogenic fire activity played a dominant role in the region, and the temporal pattern of fire activity was asynchronous from east to west. Archaeological evidence suggests an inverse relationship between agricultural and population levels and fire intensity during the mid-Holocene, with fire intensity being influenced by the diversity of landscape types associated with pre-historic subsistence patterns. Overall, changes in regional water-level delayed the transition from hunting-gathering to agriculture in the lower Yangtze region.

Summary: This paper argues that sessile barnacles are an excellent proxy for palaeoenvironmental reconstructions. The shells of barnacles consist of diagenetically stable low-magnesium calcite and record short-term variations. Analyses of several Western Mediterranean barnacle-rich deposits demonstrate the utility of barnacles as proxies for water depth, distance from the coastline, and hydrodynamic conditions. Moreover, the stable isotope ratios of barnacle shells can provide detailed palaeoenvironmental information.

Summary: The Late Ordovician mass extinction occurred during an ice age, with maximum ice coverage and a substantial drop in global sea level. This led to the exposure or shallowing of shallow tropical shelf environments. The study suggests that the burial rate of nutrient phosphorus (P) on shelves was minimal during this glacial period, leading to excess bioavailable P entering the open ocean and stimulating phytoplankton production, which in turn lowered oxygen concentrations.
