Summary: This study revised the systematics of the land snail genus Formosana from Taiwan using molecular, morphological, and anatomical data. A total of 12 valid and endemic species and subspecies were recognized, and the variability in morphological characteristics and their taxonomic implications were discussed. The biogeography and diversification of Formosana in Taiwan were also examined.

Summary: A new genus and species of anurognathid pterosaur from the Middle-Late Jurassic of China is described, providing new information on morphological diversity for the group. A new phylogenetic analysis places anurognathids as the sister-group of Darwinoptera + Pterodactyloidea within the Monofenestrata.

Summary: In this study, 132 specimens of Ovulidae were collected, including 54 individuals of Sandalia bridgesi and three individuals of Sandalia triticea. Comparisons of genetic sequences revealed a high similarity between S. bridgesi and S. triticea, supporting the proposal that S. bridgesi should be synonymised with S. triticea.

Summary: The native dart-sac-bearing camaenids Laeocathaica in Central China have been revised, revealing the presence of seven new species. The study emphasizes the importance of the proximal accessory sac in the dart-sac apparatus, which plays a significant role in diagnosing Laeocathaica species. Geometric morphometric methods were used to study species with similar shell morphology, and molecular phylogenetic analysis suggests that Laeocathaica might be monophyletic. The study also highlights the need for a thorough revision of dart-sac-bearing camaenid taxonomy in the region.

Summary: Salamanders, as model organisms, play an important role in studying various aspects of tetrapods. However, their origin and early radiation are still poorly understood. A recent study in Scotland discovered fossils from the Middle Jurassic that represent almost the complete skeleton of an enigmatic stem-salamander called Marmorerpeton. Using computed tomography, the researchers were able to study the anatomy of this early salamander in detail and also conducted a phylogenetic analysis to understand its relationship with other species. The findings provide new insights into the evolutionary changes in salamanders and the origins of Batrachia and Lissamphibia.

Summary: A new genus of viviparid snail, Dalipaludina gen. nov., is described from the Yunnan Plateau of China, using an integrated taxonomic approach combining mitochondrial COI marker and morphology. Dalipaludina is distinguished from other viviparid genera by unique shell, operculum, and radula characters. Four species are assigned to the new genus, Dalipaludina delavayana comb. nov., Dalipaludina oxytropoides comb. nov., Dalipaludina occidentalis comb. nov., and Dalipaludina pyramidella comb. nov., and one species is newly assigned to Margarya, Margarya dianchiensis comb. nov. The four species of Dalipaludina are found in allopatric distribution in shallow water lentic habitats at high altitudes on the Yunnan Plateau.

Summary: Although soft tissues of coleoid cephalopods are rarely preserved in the fossil record, the unique 3-D soft tissue preservation of Vampyronassa rhodanica from the Jurassic Lagerstatte of La Voulte-sur-Rhone provides an exceptional opportunity to observe these tissues and compare them with extant species. The study reveals that some key characteristics of the extant Vampyroteuthis infernalis were already present in Jurassic taxa. However, there are notable differences in the trophic niches between the two taxa, suggesting that they diversified in different environments before adopting their modern deep-sea mode of life.

Summary: In this study, we sequenced and analyzed the mitochondrial genomes of nine Tonnoidean species, and reconstructed their phylogenetic relationships. The results supported the classification of Tonnoidea at the family level, but revealed uncertainty in their internal relationships. Additionally, the study suggested that species diversity within Bursidae might be underestimated.

Summary: The Mediterranean basin is a major hub for land-snail diversity, with both endemic and introduced species found in the snail genus Helix. The phylogenetic relationships among different forms of Helix in the region remain unclear due to factors such as insufficient sampling, taxonomy issues, and human-assisted transport. Evidence suggests that some populations in Europe and Anatolia are not native to those regions, but originated from the northern Levant, impacting the taxonomy and evolutionary history of the genus. The Mediterranean clade is believed to consist of four geographically separated groups that have been influenced by human-assisted dispersal, but further sampling in inaccessible countries is needed to confirm founding populations.

Summary: This study describes a new pachycormiform, Kaykay lafken, discovered in the Upper Jurassic of Argentina. Through a comprehensive review of the morphology of holostean and teleostean fishes, the researchers explored the phylogenetic relationships of the new species. The study also highlights the limited understanding of the anatomy of pachycormiform fishes.

Summary: In this study, the sequencing of 11 muricid mitochondrial genomes revealed the conservation of gene arrangement, genome size, and nucleotide composition within the family. Phylogenetic analysis supported the monophyly of each subfamily and redefined the relationships between subfamilies and genera. These findings provide new insights into the classification and evolutionary history of Muricidae.

Summary: In this study, the complete mitochondrial genomes of three species from the marine gastropod Strombidae were sequenced. The phylogenetic relationships within Strombidae were explored and several morphological similarities were observed. The results suggest a possible correlation between morphological evolution in Strombidae and paleoclimate change.

Summary: By combining analysis of genital anatomy, morphometric data, and DNA, the study confirmed the validity of Septaria tahitiana and suggested that Septaria borbonica is a subspecies of Septaria porcellana. The distribution areas of these two taxa are disjunct, with Septaria borbonica in the western Indian Ocean and Septaria porcellana in the western Pacific and eastern Indian Oceans. The possible presence of Septaria tesselata in Mayotte needs further confirmation.

Summary: The study found that rhodoliths from deeper waters are more prone to growth interruptions, while rhodoliths with higher sphericity are less affected by such interruptions. These correlations are mainly regulated by hydrodynamics, as rhodoliths in deeper waters are not turned frequently enough to prevent dieback of coralline algae forming on the underside.

Summary: An increasing number of studies report microplastic contamination in the Arctic environment. This study found that all examined bivalve specimens in a marine Arctic ecosystem were contaminated with microplastics, with differences in polymer composition and abundance between different water depths. The long-term consequences of microplastic contamination on the investigated bivalve species and the rhodolith bed ecosystem remain unclear.
