Platykopus ilycalcator, surface mesh of ichnotype RAM 277
Description
A mesh of the ichnotype for Platykopus ilycalcator, a fossil interpreted as an ursid (bear) right manus track. The specimen is accessioned and catalogued at the Raymond M. Alf Museum of Paleontology (RAM), Claremont, California, USA, as RAM 277. The fossil was collected in the Late Miocene-aged Muddy Creek Formation of Clark County, Nevada, USA, at RAM locality V94163. The specimen was named and described by Sarjeant et al. (2002).
The mesh was reconstructed using photogrammetry, in September 2012, by Stephanie Rapoport and Tristan Duque. Color photos at 4288x2848 pixel resolution were acquired with a Nikon D90 digital camera. Data were processed using BundlerTools, which in turn uses Bundler, CMVS, and PMVS2. Extraneous points were removed using MeshLab, and a surface mesh was created using a Poisson reconstruction (octree depth=9, solver divide=8). The resulting mesh, with color data, was exported in PLY format, with a total file size of 3.1 Mb. The image has been scaled, so that 1 unit on the model equals 1 mm.
The Alf Museum kindly requests that any publications resulting from these data acknowledge the museum and cite this dataset, and that a link to or copy of any resulting publications be forwarded to the museum director and/or curator.
