Surface model for right humerus of Parasaurolophus sp. (Hadrosauridae: Dinosauria)
Description: This dataset includes a 3D surface model for the right humerus 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.
File Information: The original point cloud was reconstructed using photogrammetry, on April 13, 2012. 12 color photos at 4000x3000 pixel resolution were acquired with a Nikon CoolPix L22 digital camera, and were resized to 2000x1500 pixels. Data were processed using BundlerTools, which in turn uses Bundler 0.4, CMVS, and PMVS2. The resulting raw point cloud was processed further in MeshLab 1.3.0, in which a surface mesh was produced using a Poisson surface reconstruction algorithm (Octree Depth=10, Solver Divide=9, 1 sample per node, Surface Offsetting=1). Because the original mesh represented a natural mold, normals were inverted to produce a digital cast. The mesh was scaled by comparison with measurements of the original specimen (1 unit on the model equals 1 mm), and data were exported in STL file format. This single ZIP archive contains one file with an original size of 9.3 Mb, compressed to 3.7 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.
