This specimen was collected 6 miles northeast of Newkirk, Oklahoma by C. E. Burt in May 1937. It was made available to The University of Texas High-Resolution X-ray CT Facility for scanning by Dr. Jessie Maisano of The University of Texas at Austin and Mr. Alan Resetar of the Field Museum. Funding for scanning and image processing was provided by a National Science Foundation Assembling the Tree of Life grant (EF-0334961), The Deep Scaly Project: Resolving Squamate Phylogeny using Genomic and Morphological Approaches, to Drs. Jacques Gauthier of Yale University, Maureen Kearney of the Field Museum, Jessie Maisano of The University of Texas at Austin, Tod Reeder of San Diego State University, Olivier Rieppel of the Field Museum, Jack Sites of Brigham Young University, and John Wiens of SUNY Stonybrook.

The specimen was scanned by Richard Ketcham on 9 December 2004 along the coronal axis for a total of 614 slices. Each 1024x1024 pixel slice is 0.021 mm thick, with an interslice spacing of 0.021 mm and a field of reconstruction of 9 mm.
