Summary: This study describes partial remains of a non-pterodactyloid pterosaur from Upper Jurassic levels in northern Chile, likely belonging to the Rhamphorhynchinae clade, with associated ammonoids indicating a middle Oxfordian age. This discovery represents the oldest known pterosaur found in Chile and the first of Oxfordian age in Gondwana, suggesting a global distribution of Rhamphorhynchidae during the Late Jurassic.

Summary: The discovery of belemnite remains in Sarawak, Borneo suggests a widespread palaeobiogeographic distribution of the Hibolithes genus during the Jurassic-Cretaceous transition. The specimens found in the Pedawan Formation indicate a Tithonian-Hauterivian age, with characteristics such as multiple fractures and vein filling observed in the fossils.

Summary: This study introduces a new coprinoid mushroom species, Coprinopsis afrocinerea, from Pakistan, which is reported for the first time in Asia. Through morphological and molecular analysis, the specimens collected in Pakistan were identified as Coprinopsis afrocinerea, matching the type samples from Africa. The known number of Coprinopsis species in Pakistan has increased from seven to eight.

Summary: This study reports the discovery of Engelhardia fossil winged fruits with detailed anatomical structures from the Miocene Erzitang Formation of Guangxi, South China, suggesting that Engelhardia had reached its modern distribution during the Miocene. The unique anatomical and morphological features of the new fossils clearly distinguish them from other fossil genera and show unambiguously their attribution to the genus Engelhardia.

Summary: This article reports a fossil of Jacobsoniidae preserved in Holocene copal from Tanzania. The discovery expands the family's distribution range and supports the relevance of younger resins in preserving pre-Anthropocene arthropods. However, human activity may be causing the loss of local biodiversity.

Summary: Based on known fossil records, most crocodylians in Australia during the Cenozoic Era belonged to the extinct clade Mekosuchinae, with only two species of Crocodylus remaining today. The discovery of Gunggamarandu maunala challenges the dominance of Mekosuchinae in Australia during most of the Cenozoic, marking the southern-most global record for Tomistominae. Phylogenetic analysis places Gunggamarandu as a basal species within Tomistominae, suggesting a potential lineage between European and Australian tomistomines dating back over 50 million years.

Summary: In this paper, the discovery of several coleoid jaws in the lower Toarcian black shales along the Vilyui River (Yakutia, Russia) is described. It is the first time that a Lower Jurassic coleoid jaw has been recorded outside Europe, and the first report of such a finding from the Mesozoic in Siberia. The preservation and morphology of the described coleoid jaws are similar to the coeval jaws previously reported from Europe, which is made possible by the widespread occurrence of black shale facies associated with the early Toarcian oceanic anoxic event (TOAE) in Siberia.

Summary: A comprehensive paleomagnetic study of the La Mora Formation provides insights into the paleogeographic position of the Acatlan-Oaxaquia block during the Late Triassic-Early Jurassic and its subsequent northward transport during the Pangea break-up. The study also suggests a southern position of the La Mora Formation during the Late Triassic based on detrital zircon provenance ages. The magnetic properties of the sediments indicate a primary origin and a slight tectonic overprint.

Summary: Burkesuchus is a basal mesoeucrocodylian species from southern Chile, representing one of the few non-pelagic Jurassic crocodyliform records in South America. Its discovery expands the knowledge of the poorly understood Jurassic reptilian fauna in Patagonia. The phylogenetic analysis places Burkesuchus as a basal member of Mesoeucrocodylia, contributing to the understanding of crocodyliform evolution in South America during the Late Jurassic.

Summary: A well-preserved and incomplete tooth from the Late Jurassic Tacuarembo Formation in Uruguay is identified as belonging to the Abelisauridae family, marking the first record of abelisaurids in Uruguay and one of the few Jurassic findings of this group globally. The discovery also reveals a diverse Late Jurassic theropod assemblage, consisting of abelisaurids, ceratosaurids, and megalosaurines.

Summary: This study analyzed the morphological and molecular characteristics of a M. aurascens bat from Inner Mongolia, China, and determined its taxonomic status. The results showed that M. aurascens should be considered a distinct species rather than a synonym of M. davidii.

Summary: Conservation scientists studied the extinction risk of Australian freshwater fishes and found that extinction is clustered in both recently diversifying and older, species-poor groups. The loss of highly threatened species would diminish the tree of life more than a random model of extinction. The study also identified high-priority species for conservation actions based on their extinction risk and evolutionary uniqueness.

Summary: Reconstructing phylogenetic relationships among species is essential for biological and evolutionary research. The lack of genome-scale data in chondrichthyans has hindered phylogenetic and evolutionary studies of these species. However, the use of genomic exon markers from ray-finned fishes has proven to be applicable in chondrichthyan phylogenetics.
