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 oVert Thematic Collections Network||The oVert (openVertebrate) Thematic Collection Network (TCN) will generate and serve high-resolution digital three-dimensional data for internal anatomy across vertebrate diversity. At a network of digitization centers across the US, we will CT-scan >20,000 fluid-preserved specimens representing >80% of the living genera of vertebrates. This will provide broad coverage for exploration and research on all major groups of vertebrates. We will also generate contrast-enhanced scans to reveal soft tissues and organs for a majority of the living vertebrate families. This collection of digital imagery and three-dimensional volumes will be open for exploration, download, and use to address questions related to the discovery of new species, documenting patterns of anatomical diversity and growth, and testing hypotheses of function and evolution. These new media will provide unprecedented global access to valuable specimens in US museum collections. Our network of leading US vertebrate collections will develop best practices and guidelines for high-throughput CT-scanning, including efficient workflows, preferred resolutions, and archival formats that optimize the variety of downstream applications. We will train museum specialists on the generation, curation, and distribution of 3D data, researchers in using 3D anatomical data, and high school and undergraduate students in the tools for creating 3D anatomical models. To drive the use of these digital specimens by K12 STEM educators, we will conduct teacher-driven workshops that generate freely available lesson plans focused on specific science standards that are based on digital and printed 3D models of specimens in US museum collections. Data generated by oVert will serve as a catalyst for diverse research projects focused on understanding the vertebrate morphological diversity and dramatically increase the accessibility of specimens housed in US scientific collections. These anatomical phenotypes represent a common currency that facilitates integration across the fields of taxonomy, evolution, developmental biology, comparative physiology, functional anatomy, paleontology, and ecology. We will use x-ray computed tomography (CT) scanning to generate high-resolution digital anatomical data, represented as both 2D image stacks and 3D volumes and surfaces, which can be distributed globally through the on-line data portal MorphoSource. With these 3D digital specimens, US and international research communities will be able to (1) diagnose, describe, and infer patterns of relationships among both living and extinct vertebrates, (2) test hypotheses of morphological evolution such as patterns of disparity, modularity, and phenotype-environment correlations, (3) develop structure-function models for testing hypotheses about morphological adaptations related to, e.g., feeding and locomotion, and (4) explore relationships between brain and nervous system anatomy and both sensory and musculoskeletal function. We will upgrade the interface and functionality of MorphoSource, an on-line data depository for 3D data of biological specimens, improving its capacity to explore media, capture standardized metadata, ingest legacy data from previous and existing projects, supply media information to data aggregators including iDigBio, and engage educators and students. We will support training workshops both on-site at participating institutions and national society meetings of scientists and educators.||Blackburn, David||15978||10019|

|Display all details of Triassic stem caecilian supports dissorophoid origin of living amphibians||Living amphibians (Lissamphibia) include frogs and salamanders (Batrachia), and the limbless worm-like caecilians (Gymnophiona). The estimated Paleozoic gymnophionan-batrachian molecular divergence suggests a major gap in the record of crown lissamphibians prior to their earliest fossil occurrences in the Triassic Period. Recent studies find a monophyletic Batrachia within dissorophoid temnospondyls, but the absence of pre-Jurassic caecilian fossils has made their relationships to batrachians and affinities to Paleozoic tetrapods controversial. Here we report the geologically-oldest stem caecilian, a crown lissamphibian, from the Late Triassic of Arizona, USA, extending the caecilian record by ~35 Ma. These fossils illuminate the tempo and mode of early caecilian morphological and functional evolution, demonstrating a delayed acquisition of musculoskeletal features associated with fossoriality in living caecilians, including the dual jaw closure mechanism, reduced orbits, and the tentacular organ. The provenance of these fossils suggests a Pangean equatorial origin for caecilians, implying that living caecilian biogeography reflects conserved aspects of caecilian function and physiology in combination with vicariance patterns driven by plate tectonics. These fossils reveal a combination of features unique to caecilians alongside features shared with batrachian and dissorophoid temnospondyls, providing new and compelling evidence supporting a single origin of living amphibians within dissorophoid temnospondyls.||Kligman, Ben||8||8|

|Display all details of Hyneria lindae||Thomson (1968) described and diagnosed the tristichopterid Hyneria lindae from parts of a disarticulated skull and isolated scales recovered from the Late Devonian (Famennian Age) Catskill Formation of Pennsylvania, USA. Since the publication of that description, knowledge of the tristichopterid clade has grown significantly with numerous new descriptions of Famennian taxa from around the world. Additionally, a concerted effort to collect vertebrates from the Catskill Formation in Pennsylvania has produced significant new material of Hyneria lindae from the type locality at Red Hill, Clinton County, Pennsylvania. The new material serves as the basis for a rediagnosis and redescription of Hyneria lindae. The species is uniquely diagnosed by features including scales with a fringed free margin, a wide and blunt snout, and short intertemporals. The redescription of H. lindae gives occasion to review all of the Catskill Formation tristichopterid material that require further diagnosis. This includes a near complete cranial specimen collected near Red Hill that was originally diagnosed as Eusthenodon wängsjöi by Thomson (1976) and is here revised as Hyneria cf. lindae and figured for the first time. The emerging sample of tristichopterids from the Catskill Formation informs the diversity and paleobiogeography of these large predators in the fluvial ecosystems of the Red Hill site and within the Catskill Delta complex.||46||22|
|Display all details of Academy of Natural Sciences of Drexel University Vertebrate Paleontology Collection||Vertebrate paleontology in the United States originated in Philadelphia through the efforts of physicians and natural historians associated with the American Philosophical Society and The Academy of Natural Sciences. Native Philadelphian, Dr. Joseph Leidy (1823-1891) was a particularly brilliant anatomist working at the Academy during the growth of paleontology as a scientific discipline. Many call Leidy the father of vertebrate paleontology in this country. Edward Drinker Cope, another Philadelphian, made tremendous contributions to vertebrate paleontology from his home base at the Academy. The historical core of the Academy's collection includes the Thomas Jefferson Fossil Collection, the first dinosaur fossils from North America, the only fossil collected by Lewis and Clark, as well as the extensive collections of Leidy and some of the Cope collections. Although many of these specimens have great historical value, they also remain crucial for primary research. Today, the vertebrate fossil collection houses more than 22,000 specimens and that number is rapidly growing through recent research efforts. In order to make these important specimens more readily available to the research community the Academy is creating and sharing 3-D data of the Vertebrate Paleontology Collection.||64||29|
