The Elephant Bird is a type of large, flightless bird that lives in Madagascar. It has three genera: Elephantornis, Elephantornis genus and Elephantornis genus. It was extinct at least before the 16th century. The elephant bird was once considered the largest bird to have ever existed in the world, with a height of more than three meters and a weight of half a ton, until it was surpassed by the fossil of the terror bird (Phorusrhacidae) in October 2006. Adult birds and eggs of "Longnia" have been discovered one after another, and the long axis of some eggs is even 1 foot long (34cm long). Today, four species are classified under the genus A. hildebrandti, A. gracilis, A. medius and A. maximus (Brodkorb, 1963), but this classification is not entirely without controversy, and some The author of will classify it in the same species A.maximus. Elephant birds belong to the order Paleognatha, and are closely related to ostriches. They are flightless and have no keel ridge on their sternum.
