''Australornis'' (Latin: "southern bird") is a genus of extinct seabird discovered in New Zealand. It lived in the Paleocene epoch, 60.5 to 61.6 million years ago (Ma).〔 The type species name originates from ''australis'', Latin for "southern", and ''ornis'', the Greek word for "bird", and ''lovei'' commemorates Leigh Love, an amateur paleontologist who discovered it.〔 ''Australornis'' is one of the oldest flying seabirds.〔 It is also the first non-sphenisciform (penguins and allies) bird fossil discovered from New Zealand for that age.〔 The fossil originates from an era just after the Cretaceous–Paleogene extinction event 65 million years ago.〔 The features of the bird indicate that it does not belong to any of the extant bird families, but to a precursor group or clade which is extinct; hence it is a find of global significance with regard to the evolution of birds.〔 Though the fossil evidence is incomplete to substantiate phyllogeny, ''Australornis'' contributes to the emerging view that the diversification of Neoaves had already begun in the earliest Paleogene.〔 ''Australornis'' is also of zoogeographical significance, as New Zealand was much closer to Antarctica during the Late Cretaceous and Early Paleocene and it would have originated over deep waters of a warm sea off the coast of Zealandia, now a nearly submerged continent or microcontinent that sank after breaking away from Australia between 60 and 85 million years ago and on which New Zealand rests.〔 ==Discovery== The fossil was discovered in 2009 by Leigh Love in the Waipara greensand Paleocene fossil deposits of north Canterbury on the South Island of New Zealand. The fossil was deposited in the Canterbury Museum, Christchurch, where it lay in museum shelves for a number of years, as earthquakes severely affected the working of the Museum staff.〔 The fossil was described in 2014 by Dr Gerald Mayr, from the Senckenberg Research Institute and Natural History Museum in Frankfurt-am-Main, and Dr Paul Scofield of the Canterbury Museum, who published their findings in the ''Journal of the Royal Society of New Zealand''.〔 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「Australornis」の詳細全文を読む スポンサード リンク
