Media are grouped by projects created by users. Projects tend to contain media tied together by a theme. A project might represent the dataset for a single peer-reviewed paper, the results of a collections digitization project, or data for a digital lesson plan.
Projects can be used to share media ownership and access between project members, and projects can also be used to publish assortments of media and specimens for access and discovery by the public. If you want to share media ownership and access with multiple users across multiple projects, consider creating a user team. Projects can be managed by teams, and users with access to that team also gain access to any projects managed by that team.

| Display all details of Isolated UK Bathonian ornithischian teeth | CT scans and 3D models of isolated ornithischian teeth from Woodeaton & Kirtlington quarries (Oxfordshire), Hornsleasow quarry (Gloucestershire) and Watton Cliff (Dorset). Current research suggests ornithischians originated in the Middle to Late Triassic, achieving global dominance, with the Middle Jurassic a pivotal period in which the clade underwent rapid diversification and radiation. However, fossils of Middle Jurassic ornithischians are rare, with few named taxa and numerous occurrences of isolated teeth with disputed identifications. Here, we apply detailed morphological comparisons, to a suite of isolated ornithischian teeth from Bathonian microvertebrate sites in the UK, to assess the taxonomic affinities of the teeth. Undertaking these morphological comparisons has revealed a hitherto unknown, and highly diverse, ornithischian fauna from these sites which significantly increases the known diversity of ornithischian dinosaurs from this time period in the UK. The comparisons indicate the presence of six distinct ornithischian morphotypes: an indeterminate ornithischian, a heterodontosaurid, two indeterminate thyreophorans, a stegosaur and an ankylosaur. These results confirm the predictions made by phylogenetic studies that Ornithischia rapidly diversified in the Middle Jurassic, fill in temporal gaps in lineages and include one of the oldest global occurrences of stegosaurs. In addition, the mixture of non-eurypodan and eurypodan morphotypes identified here suggests that not only did non-eurypodans survive until at least the Middle Jurassic but they also co-existed in close temporal and spatial proximity with early eurypodans. | Simon Wills | 7 | 7 | |

| Display all details of Camp Century Subglacial Sediments | Basal materials in ice cores contain information about paleoclimate conditions, glacial processes, and the timing of past ice-free intervals all of which contribute toward understanding ice-sheet stability and contribution to sea-level rise in a warming climate. Only a few ice cores have been drilled through ice sheets to the underlying sediment and bedrock, producing limited material for analysis. The Camp Century ice core, which was drilled in northwest Greenland from 1960-1966 CE, recovered 3.44 meters of sub-glacial sediment that was not thoroughly studied at the time. Here, we document the scientific history of the Camp Century sub-glacial sediment, and present our core-cutting, sub-sampling, and processing methodology for this unique archive. We documented, described, and then cut each frozen archived sample (n=26). We saved an archival half and then cut the working half into eight oriented sub-samples under controlled temperature and light conditions for varied physical, geochemical, isotopic, sedimentological, and biological analyses. Our approach maximized sample usage for multi-proxy analysis, minimized contamination, and preserved material for future analyses of this legacy sample material. Grain size, bulk density, sedimentary features, ice content, pore ice pH and conductivity, and magnetic susceptibility measurements suggest that the basal sediments contain five stratigraphic units (from bottom to top): a diamicton with sub-horizontal ice lenses (Unit 1); vertically-fractured ice bearing few dispersed fine sediments (< 20% in mass) (Unit 2); a graded bed of pebbles to very fine sand in an icy matrix (Unit 3); bedded very fine to fine sand (Unit 4); and bedded medium to coarse sand (Unit 5). Plant macrofossil remains are present in all samples and most abundant in Units 3 and 4; insect remains were present in some samples (Units 1, 3, and 5). Camp Century basal units are comprised of multiple facies that represent different depositional environments in sub-glacial and ice-free conditions. Our approach provides an example for future studies of ice-core basal sediments because it includes intentional planning of core sub-sampling, processing methodologies, and archiving strategies to optimize the collection of paleoclimate and glacial process data from rare sediment archives of limited size. Our work benefited from an archive that was carefully curated and preserved allowing for the application of techniques not available when the core was recovered nearly six decades earlier. Preserving uncontaminated core material for future analytical capabilities is an important consideration for rare archive materials such as these from Camp Century. | 100 | 1 | ||
| Display all details of New sauropod trackways from the Middle Jurassic of Portugal: a correction | The Galinha dinosaur tracksite (Portugal) was declared a Natural Monument in 1996 and is currently designated as Ourém/Torres Novas Dinosaur Footprints Natural Monument. This tracksite yields a completely new and unique morphology of sauropod tracks from the Middle Jurassic (Bajocian-Bathonian). This new morphotype was attributed to Polyonyx igen. nov. Santos et al. (2009). However, recently it has been brought to our attention that this ichnotaxon name "Polyonyx" is preoccupied by the porcellanid decapod genus Polyonyx Stimpson, 1858 (Crustacea: Decapoda: Anomura: Porcellanidae). The priority is given to the latter and to avoid homonymy, the former is issued a new replacement name Galinhapodus igen. nov. and new replacement combination name Galinhapodus gomesi. | Christian A.

| Display all details of Cretaceous bird from Brazil informs the evolution of the avian skull and brain | Micro-CT scan stack, 3D meshes of the individual bones and 3D meshes of the reconstructed endocranium and exocranium of MPM-200-1, holotype of Navaornis hestiae. The scanning process flipped the orthoslices so that the resulting models are mirror images of the real fossils. | Guillermo Navalón | 23 | 1 | |

| Display all details of Mouthpart morphology: Trigonotarbida, Amblypygi, Uropygi, Ricinulei | Trigonotarbida, an extinct order of spider-like arachnids, were significant predators between the late Silurian and early Permian. Characterised by their segmented opisthosoma, clasp-knife chelicera, and paired book lungs, they played a pivotal role in the formation of Early Devonian terrestrial ecosystems. However, the compression-fossil or mould preservation of most trigonotarbids has been a limiting factor in understanding their fine morphology. Here, we re-examine the mouthparts of Palaeocharinus spp., a trigonotarbid genus from the ~408 Ma Rhynie Chert of Scotland. Rhynie preserves the palaeocharinid trigonotarbids in three dimensions with extraordinary fidelity, offering detailed insights into their anatomy, feeding and hunting behaviours, and phylogenetic position. Here we present the first Confocal Laser Scanning Microscopy (CLSM) data for Palaeocharinus using three-dimensional modelling to reconstruct the morphology of a tiered filtration apparatus, comprising a coarse outer mesh of interlacing plumose setae and a fine inner filter of pinnate setae. Together with the clasp-knife action of the chelicera and mastication by the cheliceral teeth, Palaeocharinus emerges as a sophisticated terrestrial predator with a feeding mechanism resembling that of extant representatives of Pedipalpi (Amblypygi + Uropygi + Schizomida). Phylogenetic analyses with new and modified mouthpart characters affirm the placement of Trigonotarbida within Pantetrapulmonata (Aranaeae + Pedipalpi). This study provides insights into the evolutionary innovations that facilitated the diversification and proliferation of trigonotarbids in early terrestrial landscapes. | Long, Emma J.; Clark, Brett; Terada, Masako | 13 | 10 |
