Ostriches are large flightless birds. Two living species are recognised, the common ostrich, ... It is therefore most likely that Struthionidae originated in Asia. [8]

[12] [13] So did Europe in the Paleocene and Eocene, from where the first flightless paleognaths are known.

Struthioniformes is an order of birds with only a single extant family, Struthionidae, containing the ostriches.Several other extinct families are known, spanning across the Northern Hemisphere, from the Early Eocene to the early Pliocene, including a variety of flightless forms like the Paleotidae, Geranoididae, Eogruidae and Ergilornithidae, the latter two thought to be closely related to ...
