Apatosagittarius is an extinctmonotypicgenus of Accipitridae from the Late Miocene of Nebraska. Only one species has been described, Apatosagittarius terrenus. The genus name, which Feduccia and Voorhies translate as "false secretarybird,"[1][2][3] refers to the bird's superficial resemblance to the living secretary bird.
