Struthioniformes
Also known as Ratitae, Ratite, Ratites, Struthioniform, Struthioniforms
Struthioniformes is an order of birds with 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 Palaeotididae, Geranoididae, Eogruidae and Ergilornithidae, the latter two thought to be closely related to Struthionidae.
AI overview
Struthioniformes is an order of birds that today includes only ostriches, but in the past contained many different flightless species spread across the Northern Hemisphere from about 56 million to 3 million years ago. Understanding this order helps scientists piece together the evolutionary history of flightless birds and how diverse this group once was before most species went extinct.

鸵鸟目（学名：Struthioniformes）在动物分类学上是鸟纲古颚下纲的一个目，包括很多巨大不能飞的鸟，如鸵鸟。这一目只包括一科一属，即鸵鸟属，原來鹤鸵、鸸鹋等动物亦属于这一目，但现在已经独立为鹤鸵目，使鸵鸟目只余下各种鸵鸟。现在於Charles C. Sibley利用DNA分析所作之新分類法，鸵鸟目變成鸵鸟下目，和美洲鸵鸟下目(美洲鸵鸟目)合組鸵鸟亞目，鸵鸟亞目再和鹤鸵亚目合組鸵形目。 鸵鸟目共有五种，其中阿拉伯鸵鸟已于1941年灭绝。鸵鸟是现代生存的最大的鸟类，人类已经开始驯化它们，以获取羽毛和肉、卵。 参考文献 查 论 编 鸟类现代分类（DNA分类系统，传统分类系统） 小纲 目 平胸亚纲（Paleognathae） 无翼鸟目（Apterygiformes） 鹤鸵目（Casuariiformes） 美洲鸵鸟目（Rheiformes） 鸵鸟目（Struthioniformes） 䳍形目（Tinamiformes） 雞雁小綱（Galloanserae） 雁形目（Anseriformes） 鸡形目（Galliformes） 新鸟小纲（Neoaves） 鸊鷉目（Podicipediformes） 鹱形目（Procellariiformes） 鹈形目（Pelecaniformes） 鹳形目（Ciconiiformes） 隼形目（Falconiformes） 鹤形目（Gruiformes） 鸻形目（Charadriiformes） 鸽形目（Columbiformes） 雀形目（Passeriformes） 鹦形目（Psittaciformes） 鹃形目（Cuculiformes） 鸮形目（Strigiformes） 夜鹰目（Caprimulgiformes） 雨燕目（Apodiformes） 鼠鸟目（Coliiformes） 咬鹃目（Trogoniformes） 佛法僧目（Coraciiformes） 鴷形目（Piciformes） 犀鸟目（Bucerotiformes） 鵑鴗目（Leptosomatiformes） 麝雉目（Opisthocomiformes） 企鹅目（Sphenisciformes） 潜鸟目（Gaviiformes） 叫鶴目（Cariamiformes） 这是一篇與鳥類相關的小作品。你可以通过编辑或修订扩充其内容。 查 论 编 取自“https://zh.wikipedia.org/w/index.php?title=鸵鸟目&oldid=47915494” 分类： 鸟类 鸵鸟目 古颚总目 隐藏分类： 物种微格式条目 含有拉丁語的條目 全部小作品 鳥類小作品

Struthioniformes is an order of birds with 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 Palaeotididae, Geranoididae, Eogruidae and Ergilornithidae, the latter two thought to be closely related to Struthionidae.
== Evolutionary history == According to Mayr and Zelenkov (2021), all Struthioniformes are united by the following characters: "a very long and narrow tarsometatarsus with short trochleae for the second and fourth toes, a tubercle next to the pons supratendineus on the distal end of the tibiotarsus, as well as a shortening of all non-ungual phalanges of the fourth toe except for the proximal one" All known members of the group are thought to have been flightless. Struthioniformes were widely distributed in the Northern Hemisphere during the Eocene, including Paleotididae from Europe, and Geranoididae from North America, and Eogruidae and Ergilornithidae in Asia. The discovery of Lumbreornis, belonging to either Paleotididae or Geranoididae, suggests that Struthiorniformes probably also inhabited South America during the Eocene. Ergilornthidae would persist in Asia into the Early Pliocene, while its sister group Struthionidae likely originated from Asia. Ostriches first appeared in Africa during the early Miocene, around 21 million years ago, before dispersing into Eurasia during the late Miocene, beginning around 12 million years ago.
