Skull and neck of an adult green iguana (_Iguana iguana_, OUVC 10677), with annotations of some of the more obscure anatomical features. It was collected legally and euthanized humanely by Zoo Miami staff and provided to us for research and education. We scanned the head region on the OUµCT scanner in 2012 at a resolution of 90µm (0.090 mm). Scan data were imported into workstations running Avizo and digitally extracted the bones and soft tissues. The work on this project was done primarily by Alexandra Spaw, who at the time was an undergraduate student in Ohio University's Honors Tutorial College and now is a medical student at Ohio State University. Ryan Ridgely assembled these materials in Maya for upload here. For more 3D content on this specimen, check out the Visible Interactive Iguana site: http://bit.ly/1LzIU6x. There you’ll find 3D PDFs for download that provide comparable content to what’s here, but allowing the user more control. This model can be downloaded here as an STL.
