Summary: The translated passage discusses the evolution and extinctions of larger benthic foraminifera with conical tests of the families Orbitolinidae and Coskinolinidae. It highlights the reduced taxonomic diversity of Orbitolinidae in the Late Cretaceous, with only ten genera present. The survival of Dictyoconus Blanckenhorn from the mass extinction event at the K-Pg boundary is also noted.

Summary: This study provides an updated description and testing of the community zonation hypothesis for Late Cretaceous Western Interior Seaway (WIS) vertebrates. The results highlight significant fluctuations in vertebrate community zonation throughout time and space, shedding light on the compositional and paleoecological changes that can occur in shallow marine vertebrate communities over a 25 million year interval.

Summary: The bony palate helps distinguish between the two deepest clades of extant birds: Neognathae and Palaeognathae. The discovery of the new Late Cretaceous ornithurine Janavis finalidens provides evidence supporting the presence of an anatomically neognathous palate in some Mesozoic non-crown ornithurines, suggesting that pterygoids similar to those of extant Galloanserae may be ancestral for crown birds. This challenges previous assumptions about the ancestral palate of crown birds and calls for a reevaluation of the purported galloanseran affinities of early Cenozoic groups.

Summary: This study conducted the first survey on the biodiversity of Peracarida from Trindade Island in Brazil, revealing new species and suggesting an Indo-Pacific origin for the genus based on phylogenetic and biogeographical analyses. A comparison with the closest Abrolhos Archipelago showed a high percentage of endemic species on Trindade Island.

Summary: This study presents the upper Cenomanian rudist fauna from southern Algeria, documenting different types of rudists and stratigraphic sections. The limestones exhibit various diagenetic alterations, with the rudist fauna indicating a late Cenomanian age. The ecological succession of three rudist biofacies is recorded, and comparisons to Cenomanian rudist-bearing successions around the Mediterranean Tethys are made, emphasizing paleobiogeographic similarities with the western Mediterranean province.

Summary: The Issidae, a highly diverse planthopper family, has been the subject of controversy in terms of internal phylogeny and classification. In this study, a phylogeny of the family was inferred using molecular and morphological data. The results validated the taxonomic status of subfamilies, tribes, and generic complexes, and revealed interesting insights about the origin and split of the family.

Summary: The Late Cretaceous and Paleogene strata of the Norwegian continental shelf contain rich and diverse dinoflagellate cysts, with well-preserved assemblages allowing high-resolution biostratigraphic studies and identification of new species. This paper formally describes eight new species from the More Basin offshore Norway, discussing their key diagnostic and morphological features. These new species, ranging from early Campanian to early Danian, enhance the stratigraphic breakdown of wells across the region and wider offshore Northwest Europe.

Summary: Petrological, geochemical, and biostratigraphical investigations were conducted on samples from Jordan to understand the factors influencing phosphorite deposition. Marker species indicate the Campanian and Eocene periods. The presence of certain ecological marker species suggests the occurrence of cold periods. The composition and variations in isotope ratios indicate different periods of deep water circulation, submarine weathering, and continental weathering.

Summary: This study systematically classified belemnites at the generic and species levels based on taxonomic work with rostra from the Stramberk locality in Northern Moravia, Czech Republic. A total of 23 species within 5 genera were recorded. The study provided important stratigraphical, palaeobiogeographical, and geological interpretations, and discussed the high diversity of belemnites in the sedimentary infills. The stratigraphic distribution of studied belemnites ranged from the ?latest Tithonian/Berriasian to Valanginian, ?Hauterivian and newly Barremian. The biogeographical position of the belemnite fauna from this region was found to belong to the Mediterranean Province.

Summary: This paper reports the rediscovery of Coprinus leucostictus in southern India and southern to southeastern China, and provides a morphological description of the species. Molecular phylogenetic analysis shows that C. leucostictus and Hausknechtia floriformis are separate, but sister species. Additionally, the paper presents the phylogenetic relationships within the family Psathyrellaceae.

Summary: This study describes seven species of irregular echinoids from the Upper Cretaceous in northern Turkey and determines the age of the strata using a biostratigraphical approach. The research indicates a paleobiogeographical link to northern Europe and improves understanding of echinoid migration patterns and regional stratigraphy during the Late Cretaceous.
