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 Anguimorph lizards from the early Eocene (MP 10–11) of Cos, Phosphorites du Quercy, France and the early evolution of Glyptosaurini in Europe Squamate faunas from the early Eocene of Europe are rare. A newly discovered, early Eocene (MP 10–11 interval), locality in Cos, southwestern France has yielded an assemblage anguimorph lizards (Anguidae and Varanidae) that shed light on the early evolution of these lizards. Among them is a new glyptosaurine lizard, based on frontal material having a unique pattern and distribution of polygonal osteoderms that is distinct from that of the late Eocene taxon Placosaurus from France, and the stratigraphically older glyptosaurine Gaultia silvaticus from the earliest Eocene North America. Although fossils of some members of the Glyptosaurini have been documented from the middle and late Eocene of Europe, they are virtually unknown from the early Eocene. One isolated osteoderm is referred only to Anguidae indet. This specimen resembles osteoderms present in members of the clade Anguinae, provided that the absence of tuberclulate ornamentation is not caused by abrasion or corrosion. Varanoids are represented by an isolated frontal referred to Palaeovaranus cf. P. lismonimenos based on the ornamentation of the dorsal surface. If this identification is correct then the Cos record of this palaeovaranid represents the oldest occurrence of this species. A maxilla is identified as an indeterminate varanoid based on having plicidentine infolding along the bases of the preserved teeth. Although incomplete, this Cos herpetofauna is an important and rare discovery that provides a glimpse into the ecosystems and paleobiodiversity of the early Eocene in western Europe. 11 11

Display all details of Fruits and Seeds from the early Paleocene of Littleton, Colorado, USA The Littleton site (UCM locality 77267, UF locality 19431) is an early Paleocene (Puercan) locality from the Denver Basin with a taxonomically diverse Therian and Sauropsid record. It was discovered in 1939 and is composed of fine sands or silts from the Denver formation. Despite thorough studies of the vertebrate, or Alexander, fauna since 1973, the rich carpoflora of this locality had not been described until 2019. Carpofloras are rare, and few carpofloras are known from the early Paleocene of North America. In conjunction with the vertebrate diversity here, the Littleton flora serves as an interesting ecological snapshot of a transitional time in both angiosperm and vertebrate lineages following the K-T mass extinction. 30 8

Display all details of Lumpy jaw pathology in a Pliocene kangaroo from Chinchilla, southeast Queensland, Australia Gilbert J. Price, Julien Louys, Joanne E. Wilkinson (202X) Geologically oldest evidence of ‘lumpy jaw’ (Macropod Progressive Periodontal Disease) in kangaroos of Australia: implications for conservation management. Alcheringa: An Australasian Journal of Palaeontology. At a time of widespread concern over the prevalence of viruses and infectious diseases in global ecosystems, it is helpful to consider the history of afflictions in the geological record. Amongst captive species of Australian kangaroos, one of the most common pathological conditions observed is the occurrence of ‘lumpy jaw’, or Macropod Progressive Periodontal Disease (MPPD). Macropods (including both kangaroos and wallabies) affected by the disease commonly exhibit osteological swellings in either the mandible or maxilla, or both, including in areas surrounding the cheek teeth. Diseased individuals struggle to eat, often resulting in death. The specific cause of MPPD is unclear, although it may be multifactorial. When present in wild populations, the condition is more likely to occur in situations that result in the mass-gathering of individuals around critical resources such as drying waterholes. Here we report a case of MPPD in a Pliocene (ca. 3 Ma) kangaroo, the geologically oldest record of this condition within macropods. The fossil is identified as Osphranter ?pan and was excavated from a deposit in the Chinchilla Sand, southeast Queensland. The osteomyelitis is expressed by a noticeable lateral mandibular swelling on the horizontal ramus; this is clearly pathological and has not been observed in any other member of the species. The specific circumstance that led to the development of MPPD in this individual likely reflects palaeoenvironmental stress, principally drought, in the Pliocene ecosystem. Lumpy jaw is evidently a geologically young disease, with its higher incidence through the late Cenozoic closely tied to long-term shifts towards progressively drier and more arid conditions. Given predictions that future climate change will follow such trajectories across many regions of Australia, MPPD is expected to become an increasingly important pathology for management in extant populations. This includes conservation projects that may lead to resource-limited settings such as fenced (including re-wilding) and translocated island populations. 2 1
Display all details of Hydroxyapatite/calcium alginate composite particles for haemostasis and alveolar bone regeneration in tooth extraction wounds Tooth extractions can lead to complications such as post-extraction bleeding and bone resorption,which may result in unfavorable outcomes for implant restoration afterwards. To strive for an optimal condition for further restoration procedures, appropriate strategies, such as hemostasis or bone regeneration, are encouraged to be employed. However, the existing products are failed to meet both needs. As a widely employed tissue engineering materials, hydroxyapatite and calcium alginate both have demonstrated excellent performance in osteogenesis. However, their inferior mechanical strength poses a major limitation to their use in supporting the contracted extraction socket, which can easily lead to alveolar crest atrophy and barely achieve satisfying results. Calcium alginate improves the mechanical strength of hydroxyapatite, enabling the formation of new bone tissue and degradable in vivo. In this study, we demonstrated the biocompatibility and haemostatic ability of nSA particles on a rat tooth extraction model. In addition, long-term observation has revealed minimal inflammation and bone tissue regeneration. Our findings suggest a promising insight for clinical applications in hemostasis and bone regeneration after tooth extraction. 9 9
