Sagittariidae
Sagittariidae is a family of raptor with one living species—the secretarybird ("Sagittarius serpentarius") native to Africa. German naturalists Otto Finsch and Gustav Hartlaub established the taxon name as a subfamily—Sagittariinae—in 1870. Although their term postdated Gypogeranidae of Vigors (1825) and Serpentariidae of Selys Longchamps (1842), the genus name "Sagittarius" (described in 1783) had priority over "Gypogeranus" Illiger, 1811 and "Serpentarius" Cuvier, 1798. A genus "Pelargopappus" is known from Miocene deposits in France. The genus "Amanuensis" is known from Miocene deposits in Africa.
