Summary: Diverse chancelloriids from two sections of the Kaili Biota in Guizhou Province, China are described, including 3 genera and 6 species. Two new species, Ar. anchoriformis and Ch. zhaoi, are identified and their unique characteristics are analyzed. The study also recognizes two flourishing ages of chancelloriids based on their distribution in South China.

Summary: The Fezouata Biota is a unique Early Ordovician fossil assemblage that revolutionized our understanding of Earth's early animal diversification. The new fossil locality Taichoute extends the temporal distribution of fossil preservation and expands the range of depositional environments. The discovery at this site provides important insights during a key evolutionary transition in the history of life on Earth.

Summary: A detailed morphological re-description and phylogenetic analysis revealed that Wushaichthys is a member of the new superfamily Thoracopteroidea, as part of the newly proposed Wushaichthyidae fam. nov. The study confirmed Wushaichthys as a thoracopteroid, but not a thoracopterid, significantly contributing to the understanding of the taxonomy and systematics of thoracopteroids.

Summary: The Shibantan Lagerstatte in South China is a well-known example of Ediacaran fossil assemblages preserved in marine carbonate rocks, dominated by benthic organisms. The fossils provide important data for understanding ecological interactions among mobile bilaterians, sessile benthic Ediacara-type organisms, and microbial mats, shedding light on the decline of the Ediacara biota and the expansion of bilaterian bioturbation and mobility across the Proterozoic-Phanerozoic transition.

Summary: This study analyzes 28 specimens of Rhamphosus from Bolca, Italy, revealing the existence of six species and expanding our understanding of Rhamphosus species diversity. The newly established species are described based on their unique rostrum shapes and other morphological characteristics. Comparison with the Rhamphosus species from the Fur Formation, Denmark is also conducted. The assignment of Rhamphosidae to the syngnathiform clade Dactylopteroidei is supported by various morphological features, making it the sister group to the Pegasidae.

Summary: This study presents a new occurrence of a discinoid brachiopod in the Iapo and Vila Maria Formations of the Parana Basin, indicating a possible connection between the Soom Shale in the Cape Basin, South Africa, and the Parana Basin during the Early Paleozoic. The new species, Kosoidea australis sp. nov., is characterized by a convexo-plane shell and a marked posterior triangular pedicle opening. The presence of this genus in different locations suggests insights into ancient earth configurations such as the supercontinent Gondwana.

Summary: Our understanding of early Cambrian bioradiation is influenced by contrasting information from small skeletal fossils and exceptionally preserved fossils. A new 'Orsten'-type fossil Lagerstatte was discovered in the upper Shuijingtuo Formation in South China, providing insights into the diverse fauna present in offshore environments during the early Cambrian. These findings suggest a close relationship between metazoans invading offshore environments and their radiation in shallow water settings. Despite being highly fragmented, cuticular fossils can help in reconstructing the picture of Cambrian bioradiation.

Summary: Understanding the evolutionary and historical development as well as the current state of a region is crucial for effective conservation strategies. This study suggests that the Southwest and Coastal regions of China have the highest terrestrial faunal-floral biodiversity and should be prioritized for conservation efforts. The Central region, despite significant evolutionary development, has experienced severe devastation and requires a balanced approach between socioeconomic development and biodiversity conservation. The Northeast and western Northwest regions do not require substantial investment in conservation measures.

Summary: Fossils from the Sinuiju Formation in north-western North Korea indicate similarities with the Yixian Formation in western Liaoning Province, China. The palaeontological evidence in the Sinuiju Basin shows that the Jehol Biota is more widely distributed and diverse than previously thought. The new fossil finds suggest that the age of the Sinuiju Formation is earliest Cretaceous. The discovery of the Sinuiju Biota adds significant new data to the study of the geographical distribution and diversity of the Jehol Biota in northeastern Asia.

Summary: The mixture ratio of small-sized limestone and shavings, as well as the minimum HRT, play crucial roles in the removal of metal ions by DAS in treating AMD. The main reaction zone is within the first 20-30 cm of the reaction column, and the removal process of metal ions and sulfate is accompanied by bio-mineralization reaction.

Summary: This passage describes the diversity and importance of sessile epibenthos in the energy flow process of the Cambrian marine ecosystem. Based on new specimens, two new representatives of the group with characteristics of cnidarians and bryozoans are described. If confirmed, these new findings can contribute to understanding the origin and early evolution of these two phyla. The discovery of more sessile epibenthos suggests a greater diversity in the benthic ecosystem of the Guanshan biota (Cambrian Series 2, Stage 4) than previously believed.

Summary: This study reviewed the contamination of HBCDs in marine biota in China and summarized their bioaccumulation and biomagnification in the marine food web. The study also discussed future research directions, including the transport and fluxes of HBCDs in the marine environment, the biomagnification in different ecosystems, and the metabolism in different marine species.

Summary: The study described fossil traces from the Tornetrask Formation near Lake Tornetrask in Lapland, Sweden, and revealed information about the early Cambrian period through analysis of the sedimentary age of zircon. The fossil trace assemblage shows similarities with early Cambrian trace fossil communities from other parts of Baltica, regions further south in modern Europe, and Greenland.

Summary: New fossil discoveries from the Grammajukku Formation in northern Lapland, Sweden, include Small Shelly Fossils (SSF), brachiopods, trilobites, and other marine organisms. These discoveries significantly increase the known diversity of the paleobiota in the region, providing new insights into the biostratigraphy and paleoenvironment of the lower Cambrian in Scandinavia.

Summary: Acrotretides are extinct micromorphic brachiopods that exhibited considerable morphological variation during their rapid evolution in the early Palaeozoic. This study uses advanced geometric morphometrics to study ontogenetic variation and allometry in the ventral valve of the oldest known acrotretide species from the early Cambrian of South China. The results show substantial shape variation for Eohadrotreta zhenbaensis, with a parabolic morphological trajectory through ontogeny, demonstrating a remarkable reversal to PC1 values equivalent to those obtained for juveniles during later ontogenetic stages.

Summary: This study reveals that the skeletons of early Cambrian mollusks and hyoliths are composed of fibrous microstructures made of calcite, which had not been discovered before. Additionally, it shows that the shells of these early animals were mainly composed of aragonite. This has important implications for understanding the significance of early biomineralization and its relationship with seawater chemistry.

Summary: This study investigates the occurrence of the early Cambrian stem-group gastropod Pelagiella madianensis and the problematic hyolith Cupitheca sp., providing insights into the origin and early evolution of the aragonitic crossed-lamellar (CL) microstructure in molluscan shells. The findings reveal the presence of the CL microstructure in early Cambrian gastropods and confirm its existence in hyoliths. This study contributes to our understanding of the evolutionary origin and architectural diversity of biomineralized mollusc shells during the Cambrian explosion, and strengthens the phylogenetic links between hyoliths and molluscs.

Summary: The study revises a small hyolith originally documented as Ambrolinevitus ventricosus based on new material, and reassigns it as Paramicrocornus. The classification analysis of Cambrian and Ordovician hyoliths reveals the evolution model of hyolith skeleton and soft-part anatomy, with Paramicrocornidae as the closest relative of hyolithids.
