Bobcat

Common Language Summary
The Visible Interactive Bobcat. This page presents our work on the 3D anatomical structure of the head and skull of the bobcat, Lynx rufus. Bobcats are among the few species of native wild cats in North America. The OHIO Bobcats are the official sports mascot for Ohio University, and although the species remains endangered in Ohio, its numbers are recovering. The featured specimen here (OUVC 9576) is the skull of a large, adult bobcat from Athens County, Ohio, supplied by the Ohio Department of Natural Resources. It was a road kill victim, as evidenced by some skull fractures visible in the imagery. The resources on this page are outgrowths of our more technical work and are intended to serve as STEM educational aids for K-12 and undergraduate students, as well as for researchers. Work on this project was done by WitmerLab PhD student Donald Cerio. The skull was µCT-scanned with a voxel size of 90 µm at the OUµCT facility. Segmentation of anatomical structures was done using Avizo; 3D PDFs were generated using Maya, Deep Exploration, and Adobe Acrobat; and movies were made using Avizo, QuickTime, and Adobe Premiere.

3D PDFs

3D PDFs allow anyone with even the free Acrobat Reader to interactively manipulate the 3D models that we generate with powerful software like Avizo. The skull and individual bones can be spun around, isolated, made transparent, hidden, etc. The files can even be saved to your local computer. We provide each 3D PDF in different resolutions and files sizes to match your interest and the power of your computer. View our mini-tutorial.
NOTE: Bugs in many browsers prevent them from running 3D PDFs in a browser window, so please save it to your system and then launch it.

3D PDF of the skull of an adult bobcat (Lynx rufus: OUVC 9576) with each bone as a separate colored object. The right side and left side can each be turned on and off or made transparent. Unpaired bones (e.g., occipital) are assigned to the right side.
