Skull of a young alligator, Alligator mississippiensis, OUVC 10389, is scrutinized with annotations highlighting some blood vessels. This skull was lawfully obtained by us from the Rockefeller Wildlife Refuge for research and educational purposes. We scanned the head area on the OUµCT scanner at a resolution of 90µm (0.090 mm). The scan data were imported into workstations running Avizo, where bones and soft tissues were digitally extracted. David Dufeau used this specimen during his dissertation research, followed by Ruger Porter who utilized it for his dissertation research on dinosaur blood vessels and their role in thermal physiology. This skull was part of the sample included in the PLOS ONE article by Dufeau and Witmer (http://bit.ly/2dWhTNZ) and a Journal of Anatomy article by Porter, Sedlmayr, & Witmer (http://bit.ly/2e0WqVg). The original CT scan data can be downloaded from Dryad (http://bit.ly/2ebdnZS), along with a 3D PDF offering comparable content that allows for more control. This model is available for download as an FBX here.
