Devincenzia

Devincenzia is an extinct genus of giant flightless predatory birds in the family Phorusrhacidae or "terror birds" that lived during the Early Miocene (Deseadan) Fray Bentos Formation of Uruguay, Late Miocene (Huayquerian) Ituzaingó Formation, Early Pliocene (Montehermosan) of Argentina, and possibly the Early Pleistocene Raigón Formation of Uruguay. The type species D. pozzi was formerly known as Onactornis pozzi. The largest possible specimen weighed up to 350 kilograms (770 lb), making it one of the largest phorusrhacids and carnivorous birds known.

The generic name Devincenzia comes from Uruguayan museum director and zoologist Garibaldi Devincenzi (1882-1943) and the specific name of D. gallinali comes from Alejandro Gallinal, another Uruguayan scientist. The specific name of D. pozzi was after the lead taxidermist at the museum, Antonio Pozzi.
