Segmentation data for left half of skull of Parasaurolophus sp. (Hadrosauridae: Dinosauria)

<p><strong>Description:</strong> This dataset includes segmentation data used to produce 3D digital models for the left half of the skull of RAM 14000 (nasal passages, endocranial cavity, and skull), a hadrosaur dinosaur referred to <em>Parasaurolophus</em> sp.</p> <p><strong>Taxon:</strong> <em>Parasaurolophus</em> sp. (Lambeosaurinae: Hadrosauridae: Ornithischia: Dinosauria)</p> <p><strong>Specimen:</strong> RAM 14000, Raymond M. Alf Museum of Paleontology, Claremont, California, USA. This catalog number comprises the articulated skull and skeleton of a single individual.</p> <p><strong>Locality and Horizon:</strong> Locality RAM V200921, Grand Staircase-Escalante National Monument, Garfield County, Utah, USA; upper part of middle unit of the Kaiparowits Formation (late Campanian, Cretaceous). Detailed locality data are on file at the RAM and are available to qualified investigators upon request.</p> <p><strong>Source Data:</strong>The original CT scan data are provided at</p> <p><strong>File Information:</strong> This archive includes trimmed scan data (Analyze file format, with .img and .hdr file extensions), segmentation labels (NRRD format, with .nrrd file extension), surface models (VTK format, .vtk file extension), a scene preview (PNG format, .png file extension), and a scene information file (MRML file format, .mrml file extension). These files were produced in the open source imaging program 3D Slicer 4.2, and may be opened using this program (available from This single ZIP archive contains a total of 11 individual files and a combined file size of 119.4 Mb, compressed to 86.4 Mb. Note that the models are mirrored relative to the original specimen, due to a glitch in the import of the CT scan data.</p> <p><strong>Additional Information:</strong> RAM 14000 was collected under United States Department of the Interior Bureau of Land Management Paleontological Resources Use Permit (surface collection permit UT06-001S and excavation permit UT10-006E-Gs). The specimen is accessioned into the permanent collection of the Raymond M. Alf Museum of Paleontology (RAM), Claremont, California, USA.</p> <p>The Alf Museum kindly requests that any publications resulting from these data acknowledge the museum and cite this dataset as well as the original Farke et al. publication, and that a link to or copy of any resulting publications be forwarded to the museum director and/or curator.</p> <p><strong>Publication Citation:</strong> Farke, A.
