Download (0 kB)

Description: This dataset includes a 3D surface model for the left half of the skull of RAM 14000, a hadrosaur dinosaur referred to Parasaurolophus sp.

Taxon: Parasaurolophus sp. (Lambeosaurinae: Hadrosauridae: Ornithischia: Dinosauria)

Specimen: RAM 14000, Raymond M. Alf Museum of Paleontology, Claremont, California, USA. This catalog number comprises the articulated skull and skeleton of a single individual.

Locality and Horizon: 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.

Source Data: The original CT scan and segmentation data are provided at:

File Information: This archive includes 3D surface model data in STL format (.stl file extension). Files include LeftSkullModelHighRes_RAM14000.stl (bone and matrix). Endocranial structures have not been segmented, and the labels were generated at a broad threshold so as to include relatively low- density regions of weathered bone and matrix (contrasting with the tighter threshold used for the companion models available at http://dx.doi.org/10.6084/m9.figshare.692151). These files were produced in the open source imaging program 3D Slicer 4.2 (available from www.slicer.org), and reformatted within the open source program MeshLab (available from www.meshlab.org). All are to scale (i.e., 1 unit on the models equals 1 mm). This single ZIP archive contains 1 file with a file size of 48.1 Mb, compressed to 25.1 Mb.

Additional Information: 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.

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.
