    Diplomystus dentatus
    Green River Formation, Wyoming, USA

    The Diplomystus was a relative of today's herring, but a considerably more fearsome predator. Its home was the ancient freshwater lake system of what is now known as the Green River formation, covering 25,000 square miles, where it roamed the waters as a surface feeder, preying on smaller fish. The ferocious-looking upturned mouth is the clue to its feeding habits, but the whole massive body and heavy dense head serve as ample indication that the smaller fry better watch out. This is an excellent and large example measuring 20½ inches in length. The body displays superb detail of preservation and preparation - the heavy spinal column and the dense structure of the head stand impressively proud of the rest of the fossil and even the finer cartilaginous bones of the caudal and anal fins display a striking three-dimensionality. With superb dark red to black coloring, the specimen contrasts fantastically with the pale yellow ground of the 27½ x 17½ inch matrix, which is framed and ready for hanging.
