Gastornis is an extinct genus of large flightless birds that lived during the late Paleocene and Eocene periods of the Cenozoic. Gastornis lived in Europe, but it had an extremely close relative in North America; the North American bird is often called Diatryma, but experts now believe they both belong in the Gastornis genus.
Gastornis measured on average 1.75m tall, while Diatryma was 2m tall. It had an remarkably huge beak, which may mean that it was carnivorous (although the beak may simply have been used for sexual display).
The closest living relatives of Gastornis are the Rallidae family, which includes crakes and moorhens.
Gastornis's name means 'Gaston's bird'; it is named after Gaston Planté , who discovered the first fossils at Geiseltal , Germany.
