The type species is ''B. ultimus''. An adult female of ''B. ultimus'' has been discovered with two eggs that may have still been inside its oviducts,〔 although some evidence suggests that the eggs may have been incubated in a nest. The size of the adult female has been estimated as at least ,〔 and the weight of ''Bonapartenykus'' has been estimated as .〔 Its diet probably consisted of insects.〔 Paleontologist Fernando Novas compared its bones to those of the nandu, a modern-day Patagonian flightless bird. The eggs of ''Bonapartenykus'' were considered unique enough for them to be designated to a new family of egg, the Arriagadoolithidae, so named for the owner of the site where the discovery was made.〔〔 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Bonapartenykus」の詳細全文を読む スポンサード リンク
