The specimen was scanned by Matthew Colbert on 6 February 2004 along the coronal axis for a total of 975 slices, each slice 0.166 mm thick with an interslice spacing of 0.166 mm and a field of reconstruction of 77.5 mm. This specimen was scanned in two passes, with and without a base. The slices from the first pass were aligned in Photoshop by Rachel Racicot to align with those from the second pass.
