title: A new fossil kangaroo species of the genus <i>Dorcopsoides</i> (Marsupialia, Macropodinae) from the late Miocene Ongeva Local Fauna, central Australia

description: The kangaroo tribe Dorcopsini is represented today by six species of New Guinean forest-wallaby. However, the group has a patchy fossil record beginning on the Australian mainland in the upper Miocene. Two species of fossil dorcopsin have been described from Australia to date one from the lower Pliocene of southeastern Australia; and another from the upper Miocene Alcoota beds of the Waite Formation in the continental interior. Here we describe a third Australian species from the Ongeva deposit, which stratigraphically overlies the Alcoota beds. <i>Dorcopsoides cowpatensis</i> sp. nov. is smaller than its congeners, <i>Dorcopsoides fossilis</i> and <i>Dorcopsoides buloloensis</i>, and differs in a combination of dental and postcranial character states. While its molars are very similar to other dorcopsins, the short, straight premolar resembles that of more derived macropodines. Its hindlimbs appear to have been ‘lower geared’ than those of <i>D. fossilis</i>, and in overall functional morphology it is similar to species of <i>Dorcopsis</i> and to the Quokka, <i>Setonix brachyurus</i>. We infer that <i>D. cowpatensis</i> was adapted to a relatively closed habitat while still being capable of a powerful bipedal hop. <i>Isaac A. R.

title: Articulated hindlimb of a small-bodied ornithopod dinosaur from the Cenomanian Griman Creek Formation of New South Wales, Australia

description: The mid-Cretaceous terrestrial deposits of southeastern Australia have yielded an unusual wealth of small-bodied ornithopod remains. Despite their numerical abundance, particularly from the Barremian–Cenomanian of New South Wales and Victoria, articulated remains are extremely rare. Here, we describe the first articulated remains of a small-bodied ornithopod, consisting of a partial hindlimb, from the Cenomanian Griman Creek Formation, which crops out in central-northern New South Wales. The hindlimb includes a number of unusual features not found in other small ornithopods, including a sharp supracondylar crest on the medial surface of the femur and a notched proximal margin of the ascending process of the astragalus. Although this combination of features appears to be unique, most known Australian taxa, including those from the Griman Creek Formation, are known only from isolated craniodental remains, making comparisons impossible. A phylogenetic analysis recovers the new specimen as an elasmarian with possible close affinities to the South American species <i>Isasicursor santacrucensis</i>. As the most complete small-bodied ornithopod yet recovered from the Griman Creek Formation, the new specimen reinforces the elasmarian affinities of at least some Australian ornithopods but also highlights the ongoing difficulties in attempting to resolve their diversity and relationships based on a highly incomplete fossil record. <i>Phil R.

title: Cool-temperate riparian floras in the Early Cretaceous rift valley of Victoria, Australia

description: To better understand the riparian floras associated with Early Cretaceous vertebrate localities in Victoria, Australia, we studied 291 palynological samples from 48 sites in the Otway and Gippsland basins. Podocarpaceae represent the major component of the open canopy forests of the Barremian–Aptian, whereas Araucariaceae are increasingly prolific in the Albian. Ferns, particularly Cyatheaceae, represent large components of the understorey flora through the Barremian–Aptian, whereas Schizaeaceae and Gleicheniaceae ferns and angiosperms are more common in the Albian. Notably, all recorded palynofloras imply a high-rainfall regime, despite the high palaeolatitude (70–85°S), through the Barremian, Aptian and Albian in Victoria. The increasingly warm conditions globally, from the Barremian to Albian, likely drove the prominent floral turnover observed, including numerous extinctions, and the rapid diversification of angiosperms. Increased competition may also have contributed to the decline in lycophyte richness and abundance, with angiosperms outcompeting lycophytes in rapidly colonizing newly available braidplain sites after flooding events. These inferences, also consistent with geochemical and palaeobotanical proxies, suggest that cool-temperate climates supported dynamic and forested floodplain environments in the Early Cretaceous rift valley of Victoria. <i>Vera A.

title: A Dataset of EEG Signals Reflecting Learners’ Interest States

description: Learning interest is widely regarded as a key factor influencing learning outcomes; however, its underlying neural mechanisms remain insufficiently understood. In this study, we constructed an EEG dataset collected in realistic learning scenarios to investigate the neural representations of learning interest. To capture interest states under two contrasting conditions—autonomy support and autonomy deprivation—we designed two EEG acquisition paradigms: an intrinsic-interest experiment and an extrinsically assigned-interest experiment. A total of 26 participants were recruited and divided into two groups. Each group completed the learning tasks according to one of the paradigms, while 16-channel EEG signals were synchronously recorded throughout the learning process. The dataset includes power features and peak-frequency indices across five canonical frequency bands. To validate the usability of the dataset, we applied five classical machine-learning models—logistic regression, support vector machine (SVM), decision tree, k-nearest neighbors (k-NN), and naive Bayes—to classify interest states, achieving mean accuracies of 98.32% and 96.42% for the intrinsic-interest and extrinsically assigned-interest datasets, respectively. This dataset provides a valuable resource for research in educational neuroscience, learning and cognitive mechanisms, and brain–computer interface applications.

title: Interpreted coralligenous rings classification and location, and interpreted fault network of the Northern Corsican Cape Platform (Gombessa 6 CAP CORSE expedition, 2021-2023)

description: This data set contains two interpreted shapefiles for the Northern Corsican Cape platform from the Gombessa 6 expedition that took place between 2021 and 2023. One shapefile is the classification and location of "coralligenous rings". The second shapefile presents the interpreted fault network. The goal of the Gombessa 6 expedition was to understand and explain the origin of the coralligenous rings. These submarine circles were discovered in 2006 by Pluquet and have been described as "coralligenous atolls" by Bonacorsi et al. (2012). These shapefiles are the results of manual interpretation of a 3-m resolution DTM (Digital Terrain Model, data collected in 2021 and 2023) and 40-cm resolution side-scan sonar data (data collected in 2013 during the CORALCORSE campaign (Clabaut, 2013) and re-processed in 2022). Ground-truth dives done during the 3-year Gombessa 6 campaign completed the description and helped to check for some uncertainties toward the classification of the rings. Concerning the fault network, it was digitized according to the reliefs observed on the DTM - see accompanying raster data set "Processed bathymetry data (GeoTIFF image) of the Northern Corsican Cape Platform (Gombessa 6 expedition, 2021-2023)". The shapefiles are in RGF93 / Lambert-93 projection. They were created using ArcGIS Desktop 10.6. The Gombessa 6 Cap Corse project was led by Andromède Océanologie and supported by Manufacture de Haute Horlogerie Suisse Blancpain and Blancpain Ocean Commitment, the Prince Albert II de Monaco Foundation, the Société des explorations de Monaco, Office Français de la Biodiversité, Agence de l’eau Rhône-Méditerranée-Corse (French Water Agency), National Geographic Society, Iris Foundation and Lemarchand Foundation. The project was also supported by La Marine Nationale (France Navy) and by Préfecture Maritime de la Méditerranée. The authors also want to thank ARTE, INPP (Institut National de Plongée Professionnelle), Les Gens Bien Production, CNC, Parc Naturel Marin du Cap Corse et de l’Agriate (France Relance program), Ushuaïa TV, AP diving, Aqualung, Nikon, Molecular, Seacam, Yamaha, Paralenz, Bigblue, Neotek, Seaowl, Marlink, Subspace, Suex, Dive System and Francqueville without whom this expedition would not have been possible.

title: Towards a Physical Alternative to Dark Matter: The Hypothesis of Cosmic Deserts and Boundary Reflections in Spacetime

description: This paper introduces the Space-time Topographical Constitution (STC) model, a novel conceptual framework positing that dark matter phenomena arise not from undetected particles but from intrinsic variations in the elasticity of spacetime fabric. The model bifurcates the universe into ``spacetime clouds'' with high intrinsic curvature facilitating matter condensation and ``cosmic deserts'' with flat geometry inhibiting mass accumulation. Furthermore, it reinterprets the Cosmic Microwave Background (CMB) as an energy reflection from a terminal spacetime boundary. Rigorous mathematical derivations, including detailed geodesic, perturbation, and topological analyses, Python-based simulations incorporating real cosmological data from Planck and SDSS, advanced sensitivity analyses, Bayesian inference, quantitative statistics, and a dedicated statistical analysis section support the model. Engineering formulations for laboratory analogs are provided, alongside a manufacturing roadmap for experimental verification. Observational evidence from SDSS voids, JWST early galaxies, Planck CMB anomalies, and recent 2023-2025 studies on cosmic voids and CMB anomalies is extensively integrated, with falsifiability criteria emphasized. This conceptual paper is self-contained, with all data, derivations, and simulations included.
