Specimen FSAC CP 330_Macroprosopon_Occipital region was scanned with a Nikon XT H 225ST uCT system housed in the Department of Earth and Environmental Sciences at the University of Michigan. Scans were collected with the following settings: energy settings, 215 kV, 115 uA; source to object distance, 353.463794708252 mm; source to detector distance, 1104.999 mm; scanned with 3141 projections; voxel size, x = 0.0639753837488959 mm y = 0.0639753837488959 mm z = 0.0639753837488959 mm; slice dimension (in pixels), x = 1222, y = 2000; number of slices, 2000 16-bit TIFF images. Original floating point grey values were scaled to span the unsigned 16-bit integer range using an offset of 4151.70947265625 and a scale factor of 4.802938109992684, where 16output = SCALE * (32input + OFFSET). Additional metadata can be found in the xtekct, ctprofile.xml, and UMMPCombinedMetadata.json files.
These files (.tiff format) provide high-resolution images of a fossil specimen complementing the formal description of the osteoglossid fish †Macroprosopon hiltoni from the Eocene (Ypresian) of Morocco.
Reconstructed CT slices for Snout region of Macroprosopon (catalog number FSAC CP 330; FSAC = Faculty of Sciences Aïn Chock, Casablanca, Morocco) as a series of TIFF images. Raw projections are not included in this dataset. The reconstructed slice data from the scan are offered here as a series of unsigned 16-bit integer TIFF images. The upper left corner of the first image (*_0000.tif) is the XYZ origin.
Reconstructed CT slices for skull of Heterotis niloticus (University of Michigan Museum of Zoology catalog number UMMZ Fish 195004) as a series of TIFF images. Raw projections are not included in this dataset. The reconstructed slice data from the scan are offered here as a series of unsigned 16-bit integer TIFF images. The upper left corner of the first image (*_0000.tif) is the XYZ origin.
Reconstructed CT slices for whole specimen of Macroprosopon (catalog number FSAC CP 330; FSAC = Faculty of Sciences Aïn Chock, Casablanca, Morocco) as a series of TIFF images. Raw projections are not included in this dataset. The reconstructed slice data from the scan are offered here as a series of unsigned 16-bit integer TIFF images. The upper left corner of the first image (*_0000.tif) is the XYZ origin.
