X-ray CT Scans of Warp corrected scans of a gar fish, Lepisosteus osseus (Field number LAB-045, Bayou LaBranche, St. Charles Parish, Louisiana. 22 March 2000, coll. Chris Scheible), for Dr. Julian Humphries. Scanned by Richard Ketcham on 1 December, 2000. The specimen was too long to scan in one uninterrupted scan, and accordingly was manually flipped at around its midpoint; ‘Gara’ represents the front half of the body. Original scans on Archive 0317. Warp corrections applied by Holly Nance, April 2001. Voxel Size X and Y=0.0769mm, Z= 0.259 mm. total of 513 slices.
