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 Clement et al. (2024) A Late Devonian coelacanth reconfigures actinistian phylogeny, disparity, and evolutionary dynamics. Nat. Comms. | Two specimens of a new coelacanth was discovered from the Late Devonian Gogo Formation, Western Australia. Part and counterpart of the holotype (WAM 09.6.148) and the paratype (NMV P231504) were CT scanned with data provided herein. | Clement, Alice | 8 | 2 | |

| Display all details of OLFACTION AT DEPTH: CRIBRIFORM PLATE SIZE DECLINES WITH DIVE DEPTH AND DURATION IN AQUATIC ARCTOID CARNIVORANS | It is widely accepted that obligate aquatic mammals, specifically toothed whales, rely relatively little on olfaction. There is less agreement about the importance of smell among aquatic mammals with residual ties to land, such as pinnipeds and sea otters. Field observations of marine carnivorans stress their keen use of smell while on land or pack ice. Yet, one dimension of olfactory ecology is often overlooked: while underwater, aquatic carnivorans forage “noseblind,” diving with nares closed, removed from air-borne chemical cues. For this reason, we predicted marine carnivorans would have reduced olfactory anatomy relative to closely related terrestrial carnivorans. Moreover, because species that dive deeper and longer forage farther removed from surface scent cues, we predicted further reductions in their olfactory anatomy. To test these hypotheses, we looked to the cribriform plate (CP), a perforated bone in the posterior nasal chamber of mammals that serves as the only passageway for olfactory nerves crossing from the periphery to the olfactory bulb and thus covaries in size with relative olfactory innervation. Using CT scans and digital quantification, we compared CP morphology across Arctoidea, a clade at the interface of terrestrial and aquatic ecologies. We found that aquatic carnivoran species from two lineages that independently reinvaded marine environments (Pinnipedia and Mustelidae), have significantly reduced relative CP than terrestrial species. Furthermore, within these aquatic lineages, diving depth and duration were strongly correlated with CP loss, and the most extreme divers, elephant seals, displayed the greatest reductions. These observations suggest that CP reduction in carnivorans is an adaptive response to shifting selection pressures during secondary invasion of marine environments, particularly to foraging at great depths. Because the CP is fairly well preserved in the fossil record, using methods presented here to quantify CP morphology in extinct species could further clarify evolutionary patterns of olfactory loss across aquatic mammal lineages that have independently committed to life in water. | 2 | 2 | ||
| Display all details of Triarthrus cephalic appendages | CT scan of trilobite specimen showing four biramous cephalic appendages plus antennae.

| Display all details of Associated materials - "Insular dwarfism in horses from the Aegean Sea and the Japanese Archipelago" - Mammalian Biology | The horse (Equus caballus) varieties from Skyros and Rhodes islands (Greece) in the Aegean archipelago and from the Japanese archipelago are extremely small. We investigated the evolutionary morphology and provided a review of historical documentations of these horses of cultural interest in Greece and Japan, thus providing a comparison of the independent evolution of small size in islands through their cranium, braincase, and inner ear. The present project corresponds to the internal data collected for this study (Ct-scans & 3D Models) currently being reviewed in the Journal "Mammalian Biology" (metadata will be updated after this process). The project will be completed with specimens during 2024. | Le Verger, Kévin | 25 | 18 | |
