There are two known species, ''P. perrierensis'' from the Upper Eocene of Quercy, France and ''P. artophoron'' from the Middle Eocene Messel shales, Germany.〔Mourer-Chauviré, Cécile (1987) "The owls (Aves:strigiformes) of Phosphorites Du Quercy (France) systematics, biostratigraphy, and paleobiogeography" pp.89-136 in "Documents des laboratoires de geologie Lyon" Départment des Sciences de la Terre, Université Claude-Bernard Lyon 1. ISBN 2-85454-029-8〕 The holotype of ''P. perrierensis'' is a partial left coracoid in the Collection Université Montpellier, accession number PRR 2585. There are four paratypes; the distal part of a left humerus (PRR2591), the proximal part of a left ulna (PRR 2571), the distal part of a left ulna (PRR 2578) and the distal part of a right tarsometatarsus (PRR 2576). The type specimen of ''P. artophoron'' are a fossil slab and counterslab containing most of the postcranial skeleton and some feather impressions. This specimen is in the collection of the Forschunginstitut Senckenberg, accession number SMF-ME 1144 A and B. The feathers of ''P. artophoron'' show some unique characteristics. The feathers on the trunk are about wide and long. They appear to be membranous and ribbon-like, without barbs This may be an artifact of preservation, but eight nearby primaries show barbs quite clearly. Peters noted that ribbon-like, elongated plumes are known from some living birds, but all are used in display. He writes that display feathers are unexpected in a nocturnal owl, and wonders if this lineage of owls was, in fact, diurnal.〔Peters, Dieter Stefan (1992) "A new species of owl (Aves:Strigiformes) from the Middle Eocene Messel oil shale" pp. 161-169 in "Papers in Avian paleontology honoring pierce Brodkorp" edited by Kenneth Campbell, Jr. NO. 36 Science Series Natural history Museum of Los Angeles County.〕 ==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「Palaeoglaux」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
