1266 Projects

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 The mandible and dentition of Borealestes serendipitus (Docodonta) from the Middle Jurassic of Skye, Scotland The Middle Jurassic docodont Borealestes serendipitus was the first Mesozoic mammal found in Scotland over 40 years ago. Its affinities and morphology have remained poorly understood. Although multiple dentary fragments and isolated teeth have been recovered from Scotland and England, they have not yet been described in sufficient detail. We report new, more complete specimens collected during recent field work on Skye, Scotland, combined with previously collected material. This includes upper and lower dentition and an almost complete right dentary. We present an updated description and diagnosis of the genus Borealestes, based on high-resolution micro-computed tomography (micro-CT) and synchrotron scans. We identify seven key features that distinguish Borealestes from other docodonts, including a pronounced a–c crest, absence of the a–g crest on cusp a, an anterior fovea at the buccolingual midpoint of the upper molar, and the convergence of the Meckel’s groove with the ventral margin of the mandible. We also present a revised diagnosis for the second species, B. mussettae. Our phylogenetic analysis supports a clade formed by Borealestes, Haldanodon, Docofossor, and Docodon. Ontogenetic variation in the mandibular morphology of Borealestes is similar to that seen in Docodon and Haldanodon, with the delayed emergence of the ultimate lower molar, the shift of the last molar to the front of the coronoid process, and a posterior shift of the Meckel’s sulcus in successively older individuals. This supports a distinctive growth pattern in the clade including Borealestes and Docodon, one that may be present in Docodonta as a whole.

Display all details of oMega This is a Partner to Existing Networks (PEN) award to the Idaho Museum of Natural History to partner with the Open Vertebrate (oVert) Thematic Collections Network (TCN). The oVert TCN is creating high-resolution three-dimensional (3D) data for internal anatomy across the diversity of vertebrate animals. Using computed tomography (CT) scanners at institutional collections across the US, more than 20,000 fluid-preserved specimens will be scanned and made available online for open public use. This PEN complements the oVert TCN program by including vertebrate animals too large to be preserved in fluid or scanned by conventional CT scanners. The oMEGA PEN will use portable surface scanners to provide high-resolution scans of skeletons of large vertebrate animals curated at Harvard, Berkeley, and California Academy of Sciences. The addition of large vertebrates, including whales and elephants, provides an important segment of the animal world to open access collections for researchers and educators. The process of creating this 3D resource will provide training for undergraduate students, and on-site workshops for collections staff. Skeletal models will support TCN activities in creating K-12 STEM lesson plans and 3D-printable resources for the classroom. The digitized skeletons acquired in this PEN will help fill a major gap in the original TCN and support its research theme on the evolution of vertebrate morphological diversity. By virtue of their large size, vertebrates exceeding 250 kg define upper boundaries of size-dependent anatomical form and function, and therefore push the limits on development and physiology. These skeletal data will provide new opportunities to evaluate gigantism and the tendency of animal lineages toward ever-larger body size. Combined with the other oVert 3D specimens, the TCN's digital collection distributed through MorphoSource and iDigBio will inspire new research questions and provide the raw materials to test hypotheses in a broad range of biosciences. "This project is a continuation of the Virtual Zooarchaeology of the Arctic Projects (VZAP, NSF-ARC#0808933, ARC#1023321). Specimens originally digitized by the Idaho Museum of Natural History as a part of VZAP are made available within the oMega collection. Funding was provided by the NSF, Office of Polar Programs (OPP), and Arctic Social Sciences" This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

Display all details of Hyperossification in the vertebral column of Devonian placoderm fishes (Arthrodira) Skeletal bone enlargement (hyperossification) is thought to only occur in endochondral and dermal bone (e.g., in the endoskeletons of marine tetrapods and the dermal bones of certain jawless vertebrates and placoderms, and teleost fishes). However, we demonstrate several types of bone enlargement in the vertebral endoskeleton of some arthrodiran placoderms (basal jawed vertebrates)—Millerosteus minor, Compagopiscis croucheri, and Eastmanosteus calliaspis. This is significant, because not only is placoderm endoskeletal bone thought to be thin-walled, it is thought to ossify only perichondrally (in the fibrous perichondrium layer surrounding a cartilage precursor), rather than endochondrally/dermally. Hyperossification differs considerably among these taxa, revealing a range of internal and external bone morphologies previously undescribed for the placoderm endoskeleton. For example, neural arches of Millerosteus minor are swollen in external appearance, in cross-section showing considerable deposition of layered, compact bone, by comparison, the neural spines are not swollen, but show considerable compact bone internally. In Compagopiscis croucheri, although the perichondral bone of both structures is thickened and compact as in Millerosteus minor, the spine and arch are unswollen externally. Similar to Compagopiscis croucheri, the spines and arches of Eastmanosteus calliaspis are unswollen externally, yet the neural spine cortex is composed of the thin perichondral bone expected for placoderms. In contrast, the arches comprise numerous layers of perichondral bone. The nature of vertebral hyperossification in these related taxa differs considerably in the degree and mode of cortical tissue thickening, via addition of tissue to the bone’s external (periosteal) and/or internal (endosteal) surfaces. Hyperossification in these arthrodires demonstrates that increases in endoskeletal bone mass are not restricted to crown group gnathostomes (Chondrichthyes + Actinopterygii), and may represent a first step in the evolution of this process, involving modifications to cortical bone layers. 3 3
