This specimen (TMM M-2749) was collected from Alaska. It was made available to The University of Texas High-Resolution X-ray CT Facility for scanning by Dr. Timothy Rowe of The University of Texas at Austin. Funding for scanning and image processing was provided by a National Science Foundation Digital Libraries Initiative grant to Dr. Rowe.
The specimen was scanned by Richard Ketcham on 22 September 2005 along the coronal axis for a total of 682 slices. Each slice is 0.55 mm thick with an interslice spacing of 0.5 mm, resulting in a slice overlap of 0.05 mm, and the field of reconstruction is 196 mm.
