Summary: Research in the southern Karoo Basin of South Africa from the Late Permian to the Middle Triassic shows evidence of at least four atmospheric carbon dioxide spikes coinciding with extinctions on land and at sea. These extinctions correlate with extreme greenhouse spikes of carbon dioxide and transient episodes of warmer and more humid climate, causing respiratory distress for vertebrates and wetland plants. This provides worst-case scenarios for modern global climate change.

Summary: A gypsum interlayer with 100 m thick was discovered in the Keban Metamorphics in southeast Turkey. The gypsum underwent hydrothermal alteration caused by late Cretaceous magmatic intrusions, resulting in dissolution, recrystallization, and the formation of secondary gypsum. The geochemical compositions of the gypsum indicate marine evaporite compositions.

Summary: This study describes a new species of Probainognathia from the Norian period in Argentina, using high-resolution neutron and X-ray micro-tomography to analyze its unique characteristics. The researchers constructed a phylogenetic data matrix of non-mammalian cynodonts and conducted a paleobiogeographic analysis. The results indicate that Probainognathia and Mammaliamorpha originated in southwestern Gondwana, with the ancestral area of Mammaliaformes being the Lufeng Basin in China.

Summary: The paper discusses the abundance, diversity, and extinction of non-marine algae in the Permian and Triassic periods, focusing on the aftermath of the end-Permian extinction interval. It also provides insights into the global biotic crises within the Permian-Triassic interval and the fossil records of non-marine algae in Gondwana. Finally, the review highlights the scarcity of quantitative fossil evidence for non-marine algae during these critical periods in evolutionary history.

Summary: This study used hierarchical cluster analysis, ordination methods, and bipartite network analysis to study the phytogeographic units of the Middle-Upper Triassic of Gondwana. The results showed a clear separation between tropical and extratropical associations, and identified a microfloristic region in southwestern Gondwana that is similar to the microfloras of northern Laurasia. These findings confirm, for the first time through quantitative methods, the distinction between different microfloras.

Summary: This paper discusses the disputed tectonic nature of the Lhasa Terrane during the Triassic period, presenting two contrasting views on its geological characteristics. The study suggests that the Lhasa Terrane may have been a low-latitude carbonate platform separated from Gondwana during the Early Triassic. Further research is encouraged to explore the Triassic sedimentary history and paleogeographic evolution of the Lhasa Terrane.

Summary: Timor is located in the Outer banda Arc and has a chaotic geology in the late Neogene collision zone. The Upper Triassic shallow-water carbonate deposits contain foraminiferal microfauna with species known from North Africa and Europe. The Bandeira Group represents extensive carbonate-platform deposits with unique characteristics compared to other units in the region.

Summary: This study presents a detailed cuticular analysis of a new species of ginkgoalean plant, Sphenobaiera insecta, from the Upper Triassic deposits in Leigh Creek Coal Measures, South Australia. The research also proposes an emendation to the genus diagnosis of Sphenobaiera. Additionally, the study discovers common evidence of a particular type of herbivory damage on the leaves of Sphenobaiera insecta.

Summary: The Guryul Ravine section in Kashmir is an important reference section for global Lower Triassic stratigraphy, providing a key conodont biostratigraphic yardstick for worldwide correlations. The newly established conodont zonation from Kashmir offers a high precision time-frame for studying biotic evolution and environmental changes during the Early Triassic, a crucial period in Earth's history.

Summary: This paper reports the alluvial trace fossil assemblages from the Upper Triassic Tiki Formation in the Rewa Basin, central India, providing information about spatio-temporal changes in palaeoenvironment and palaeoclimate. The study identifies two depositional environments and three major ichnofacies, and highlights the influence of seasonal precipitation on trace fossil preservation.

Summary: This study introduces a new Triassic insect relative with reconstructed wings, contributing to the understanding of evolutionary trends in a group with incomplete fossil remains. The standardized method used for inferring missing parts can be applied broadly to the fossil record of insect wings, providing insights into the morphological diversity and evolutionary relationships within this group. This discovery represents the first ascertained occurrence of a specific group in Gondwana, where the fossil record of Odonata is limited.

Summary: The new U-Pb dating results of rhyolite samples collected in the Late Triassic Tianqiaoling flora-bearing beds provide important chronological evidence for the development of the flora, which is consistent with paleobiological evidence. This contributes to a better understanding of the geology and phytogeography in East Asia during the Late Triassic period.

Summary: The purpose of this study was to identify risk factors for flat anterior chamber that required additional intervention after Baerveldt Glaucoma Implant (BGI) surgery. A retrospective matched case-control study was conducted, and the results showed that older age, oral carbonic anhydrase inhibitors (CAIs) at tube opening, and higher intraocular pressure (IOP) prior to tube opening were independent predictors for flat anterior chamber. Strategies to minimize acute IOP reduction were recommended to prevent this complication.

Summary: The astelioid families are mainly distributed in Australasia and temperate Africa, with secondary centers of diversity in Afromontane Africa, Asia, and Pacific Islands. The distribution patterns are believed to be influenced by long-distance dispersal and Tertiary climatic and geological drivers. Australian ancestral ranges were identified for Crown Asteliaceae and Boryaceae, while certain genera in Hypoxidaceae have African origins.

Summary: Paleocene leaf floras in high latitudes of the Southern Hemisphere show higher taxonomic diversity compared to the Northern Hemisphere, providing valuable insights into biodiversity and forest communities. The Antarctic Peninsula hosts rich Paleocene-Eocene floras used to interpret climate change and abrupt warming events. The study presents new evidence of increased angiosperm diversity in the cool-temperate Gondwanan forest on the east side of the Antarctic Peninsula during the late Paleocene.

Summary: Sphenophytes are commonly found in wet environments, and in two wetland sites in Iran, well-preserved in situ stems of a genus called Neocalamites were discovered. These stems, which have not been reported in other regions, suggest undisturbed conditions after the cessation of environmental stress.

Summary: Analyses of coprolites provide valuable data on animal feeding and food quality, shedding light on the taxonomy of the environment. This study describes plant remains found in coprolites from early Hettangian deposits at Soltykow, Poland. The coprolites are likely from herbivorous sauropodomorphs, ornithischians, and large carnivorous theropods. The findings suggest that herbivores fed on flora from a fluvial plain, while coprolites of large predators contained diverse plant remains likely ingested from prey. Palynological analysis revealed a variety of plant taxa, with Classopollis torosus dominating the sporomorph assemblage.
