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: Paleomagnetic results for a magnetostratigraphic section of Permian rocks in the Karoo Basin of South Africa are reported. The study identifies titanomagnetite as the carrier of the recorded magnetization, which represents the Permian geomagnetic field during a reverse polarity superchron and subsequent mixed polarity interval. The timing of the magnetization is further constrained by Jurassic-aged dolerite intrusions. A paleopole is calculated based on the primary remanence, and the end of the Kiaman Reverse Polarity Superchron is correlated across the basin.

Summary: This study reviews the changes in plant species richness and abundance in South China from the End Permian to Middle Triassic, and examines the co-evolutionary relationship between plants and the environment during this critical period. The study identified four phases of plant evolution, with the End Permian Plant Crisis being a significant event that marked a decline in species richness and plant abundance.

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 Late Permian coal-bearing sequences in southwest China have high concentrations of critical elements such as Sc, V, Co, Ni, Cu, Zn, Nb, Ta, Zr, and Hf. Determining the factors behind this enrichment is crucial for meeting China's critical metal demands. This study analyzed coal samples from the Guishan coalfield in eastern Yunnan, China, and found that the C4-Upper coal seam of the Feilongma mine and C5 + 10 coal seam of the Shipeng mine are particularly rich in critical elements. The enrichment of these elements is controlled by clastic terrigenous material sourced from the Kangdian Oldland in the northwest and associated with high-Ti basalts from the Emeishan Large Igneous Province.

Summary: The study analyzed fossil data from South Africa's Karoo Basin, revealing a period of high extinction rates lasting approximately 1 million years during the Permo-Triassic Transition. This period was characterized by rapid turnover and the emergence of short-lived species, indicating ecosystem instability.

Summary: This study examines the timing of the opening of the Meso-Tethys Ocean by analyzing detrital zircons from Upper Carboniferous-Upper Permian strata on the Tibetan Plateau. The data suggests a significant change in sedimentary provenance around 280-260 million years ago, indicating the opening of the Meso-Tethys Ocean.

Summary: This review critically evaluates the geological evidence and discusses the current hypotheses surrounding the kill mechanisms of the Permian-Triassic mass extinction, including the different response times of terrestrial and marine ecosystems to the Siberian Traps eruptions and the causal relations between volcanism, environmental perturbations, and ecosystem collapse.

Summary: The study analyzed coal samples from Vele colliery to determine their rank and intrinsic characteristics. It found that the dominant maceral group in the coals is vitrinite, indicating they are derived from plant tissues. The coals were classified as medium rank based on the vitrinite reflectance values.

Summary: Mass extinctions change the trajectory of evolution and restructure ecosystems. The end-Permian mass extinction is of particular interest due to the delayed recovery of global ecosystems. Diapsids, especially archosauromorphs, play a crucial role in this recovery, filling vacant niches. However, the lack of well-dated stratigraphic sections at the Permian-Triassic boundary limits our understanding of diapsid lineage and ecological diversification. The Driefontein locality in the Karoo Basin of South Africa provides valuable insight into the diapsid fossil record during the Early Triassic, with the discovery of new tooth morphotypes. The morphological analysis suggests faunivorous diets for most morphotypes, indicating previously unsampled taxonomic and ecological diversity in diapsids during this period.

Summary: Joachimski et al. conducted geochemical investigations on seawater temperature changes across the Permian-Triassic Boundary (PTB). However, due to an incorrect biochronology, their reported temperature changes showed discrepancies compared to the global stratotype section and point.

Summary: The study presents rock and paleomagnetic magnetic analyses of the lower Ecca Group in the southwestern Karoo Basin, South Africa, proposing an Artinskian to Kungurian age for the rocks. By constructing a magnetostratigraphic profile, the first composite profile spanning the entire Ecca Group in the region is produced.

Summary: The increase in palynological works in Mozambique over the past decade has shed light on the regional biostratigraphy and paleoenvironmental conditions during the Permian. The new biostratigraphic information from the Moatize-Minj ova Coal Basin calls for an update on the lithostratigraphic correlation of Lower Karoo basins in Mozambique. The palynological associations provide insights into the evolution and potential diachronism of boundaries between different geological periods.

Summary: The study compared the efficacy of acid-free processing and standard processing techniques on Permian material, finding that both methods yielded comparable assemblages of palynomorphs, with higher proportions of phytoclasts in the acid-free samples. Additional refinement of the acid-free technique and further research are recommended to improve accuracy and remove phytodasts.

Summary: The volcanic rocks of the Zamoranos Formation in the Betic Cordillera of southern Spain show Late Triassic CAMP volcanism, with similarities to volcanic rocks from the Upper Triassic of the Algarve region in Portugal. The identification of alkaline rocks preceding the main CAMP sub-alkaline phase suggests a change in mantle sources. The gradual development of rifting from west to east in the southern area of Iberia during Norian-Rhaetian times is inferred from the study.

Summary: The Campano-Maastrichtian deposits of the Nkporo and Mamu formations in the Anambra Basin in southern Nigeria represent potential hydrocarbon resources. A detailed geochemical analysis and mineralogical characterization revealed that the region experienced a warm, humid tropical paleoclimate during the Late Cretaceous. The high precipitation during the Cretaceous resulted in intense chemical weathering. The studied mudrocks were primarily deposited in brackish to shallow-marine settings with poor primary productivity and under oxic conditions.
