Research Overview: 

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.

Methodology: 

Specimen Faculty of Sciences Aïn Chock, Casablanca, Morocco (FSAC) CP 330, representing the holotype of the osteoglossid fish †Macroprosopon hiltoni from the Eocene (Ypresian) of Morocco, was photographed in both right and left lateral view using a Nikon D70 digital SLR camera by A. Capobianco. A. Capobianco, in consultation with M. Friedman, developed preliminary interpretative drawings based on these photographs. On the basis of these preliminary drawings, specimen photos, and specimen FSAC CP 330 itself, C. Abraczinskas worked with A. Capobianco and M. Friedman to develop refined sketches. These, in turn, were drafted as weighted-line drawings in Adobe Illustrator. The photographs and drawings included in the formal description of †Macroprosopon hiltoni show only the anterior or posterior half of the skull due to space and format limitations of Zoological Journal of the Linnean Society. The images (in .tiff format) provided here combine anterior and posterior portions for each side of the specimen. They are scaled at 8.5 X 14 inches with a resolution of 1000dpi.
