CT scan of left half of skull of Parasaurolophus sp. (Hadrosauridae: Dinosauria)

<p><strong>Description:</strong> This dataset includes a CT (computed tomography) scan of the left half of the skull of RAM 14000, 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>Scan Parameters:</strong> The specimen was scanned on a Toshiba Aquilion 64 scanner at Pomona Valley Hospital Medical Center, Claremont, California, USA, on December 18, 2012. Scan parameters were set at 120 kV and 400 mA, slice thickness of 0.5 mm, and reconstruction diameter of 229.687 mm, using a standard bone reconstruction algorithm, resulting in an in-plane resolution of 0.45 mm by 0.45 mm per pixel. Each slice is 512 by 512 pixels. Slices were exported in DICOM format, with a total of 531 individual files and a combined file size of 279.6 Mb. The files were compressed into a single ZIP archive, with a file size of 140.2 Mb.</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.
