Description
Zarhachis: Scans of the left petrosal of Zarhachis flagellator (USNM 13768; 200-300 yards S. of Calvert Beach; Miocene; Zone 17) for Dr. Mark Uhen of the Cranbrook Institute of Science and Dr. Lori Marino of the Department of Neuroscience and Behavioral Biology, Emory University. Specimen scanned by Matthew Colbert 11 November 2003. 16bit: 1024x1024 16-bit TIFF images. II, 180 kV, 0.133 mA, no filter, air wedge, no offset, slice thickness 2 lines (= 0.0622 mm), S.O.D. 90 mm, 1400 views, 2 samples per view, inter-slice spacing 2 lines (= 0.0622 mm), field of reconstruction 29 mm (maximum field of view 29.46449 mm), reconstruction offset 4200, reconstruction scale 1000. Acquired with 15 slices per rotation. Ring- and flash-removal processing done by Rachel Racicot based on correction of raw sinogram data using IDL routines “RK_SinoRingProcSimul”, and “RK_SinoDeSpike”, both with default parameters. Reconstructed with beam-hardening coefficients: 0.0, 0.9, 0.05. Total slices = 690. 8bitjpg: 8-bit JPG version of the above images.
