Summary: This article discusses the arido-eustasy model, which explains paleoenvironmental change by linking the carbon isotope record and eustatic sea level to hydroclimatic intensity modulated by orbital forcing. It suggests that extreme hydroclimatic intensity events, called Orbito-Hyetal Events (OHEs), play a crucial role in major paleoenvironmental crises. The study provides evidence for a strong and short-term OHE at the end of the middle Oxfordian.

Summary: This study reexamines and redescribes the type specimens and associated material of the Late Jurassic rhynchocephalian Opisthias rarus, and presents a fragment of the holotype for the first time. It also comments on undescribed material from the same quarry which may belong to an unnamed species of Opisthias. Additionally, a new specimen of Theretairus antiquus is described, rejecting its proposed status as a junior synonym of O. rarus, and contributing to the knowledge of the Late Jurassic microvertebrate fauna of North America.

Summary: Late Jurassic marine vertebrates are well preserved in central Europe, with a rare fossil chondrostean, originally named Coccolepis bucklandi, rediscovered as a new species Coccolepis solnhofensis. The two species are geographically and stratigraphically separated, emphasizing the importance of these distinctions in taxonomy.

Summary: The Late Jurassic multituberculate assemblage from the Langenberg Quarry in Northern Germany includes various species such as Paulchoffatiidae indet. and Teutonodon langenbergensis. A new species, Cimbriodon multituberculatus, was also discovered within the paulchoffatiid line.

Summary: We have described a new morganucodontan species, Cifellilestes ciscoensis, based on two skull fragments from the Cisco Mammal Quarry. The fossils preserve detailed 3D structures of the palate, snout, and complete upper postcanine dentition. The discovery of this species expands our understanding of the early evolution of mammals and the craniodental variation within the group. Ash-fall zircon analysis dates the locality to the earliest Tithonian and extends the record of morganucodontans in North America by more than 30 million years.

Summary: This is a fossil of a long-legged, spatula-beaked, filter-feeding pterodactyloid pterosaur from the Upper Jurassic period in Wattendorf, Bavaria, southern Germany. It is remarkable for its complete preservation, unusual dentition, and possible preservation of soft tissues, including wing membranes. The fossilized specimen has fully articulated jaws with over one hundred sub-parallel-sided teeth on each side, forming a fine mesh trap for filtering plankton-rich water. The slightly up swept rostrum and probable pulsating movements of the long neck assisted in filtering while wading or swimming in shallow water.

Summary: Late Jurassic deposits in Europe have revealed a diverse fauna of extinct turtles, with two new fossils from Germany showing strong evidence of open marine adaptations, similar to the Thalassemys species. While the exact taxonomic attribution of these fossils remains unclear, their elongate flippers stiffened by scales suggest adaptations for marine life. These findings provide insights into the evolution of marine adapted turtles during the Late Jurassic period.

Summary: A new species of pterosaur, Lusognathus almadrava gen. et spec. nov., has been discovered in Portugal, representing the first named pterosaur species found within the country. Its unique tooth and dentary morphology suggests affinities with the gnathosaurine subfamily and adds to the diversity and distribution of gnathosaurines worldwide.

Summary: In this study, we used DNA immunoprecipitation-seq and RNA-seq analyses to investigate the role of the transcription factor Euo in Chlamydia trachomatis. We found that Euo represses late chlamydial genes and activates a subset of midcycle genes, as well as regulating its own expression. Our findings highlight the important role of Euo as a developmental regulator in C. trachomatis and demonstrate a correlative approach that can be used to study transcription factors in other pathogenic bacteria.

Summary: The study establishes a revised GPTS for the Middle to Late Jurassic, revealing the rapid onset of the Mesozoic Dipole Low from M42 through M39 and subsequent gradual recovery in field strength into the Cenozoic. Coherency between short-wavelength anomalies in the Japanese and Hawaiian lineation magnetic anomaly sequences implies a regionally coherent field during this period of rapid geomagnetic reversals. The identification of a zone of difficult-to-correlate anomalies in both sequences suggests the presence of a core similar to the JQZ crust bounded by M39-M41 isochrons.

Summary: The Solnhofen archipelago in southern Germany has been a rich source of pterosaur fossils for the past 250 years. In this paper, a mostly complete specimen of a ctenochasmatid pterosaur is described, which is one of the largest known pterosaurs from the region. It possesses unique features such as a large bony crest and an unusual combination of teeth, shedding light on the diversity and ecology of Jurassic pterosaurs.

Summary: During lytic replication, beta- and gammaherpesviruses use a unique strategy which involves six viral transcriptional activators (vTAs) to facilitate the transcription of late genes. One of these vTAs is a viral mimic of host TATA-binding protein (vTBP) that recognizes a simplified cis-acting element. The other five vTAs' functions are largely unknown. The vTA complex and RNA polymerase II assemble on the promoter to facilitate late gene transcription.

Summary: Coccolepis bucklandi is a rare non-neopterygian actinopterygian fossil from the Late Jurassic Solnhofen Archipelago. Rediscovery of the holotype and a new specimen led to a study on morphological differences and their potential significance, raising questions about intraspecific variation and higher taxonomic diversity.

Summary: AGASSIZ's work laid the foundation for the taxonomical descriptions of numerous fish species from the Upper Jurassic Solnhofen Archipelago. While most species were well described and illustrated, there were also some species with insufficient descriptions and without accompanying images, leaving their true meaning unclear. However, AGASSIZ's commissioned fish drawings, which were unable to be published in his work, have recently been catalogued and made digitally accessible, shedding new light on his understanding of these species and the specimens he used for his research. This research is significant because it provides valuable insights into the taxonomy of Solnhofen Archipelago fish species.
