Fossils have been found in Mongolia, Germany, and Spain.〔(Paleobiology Database: Proailurus )〕 One recent phylogeny places it as a basal member of the Feliformia, the suborder that includes mongooses, civets, hyenas, and cats; but other studies suggest that it instead was a felid (a true cat). ''Proailurus'' was a compact and small animal, just a little larger than the domestic cat, weighing about 20 lb (9 kg). It had a long tail, large eyes and sharp claws and teeth, with similar proportions to the modern viverrids. Its claws would have been retractable to some extent. Like the viverrids, ''Proailurus'' was at least partially arboreal. ''Proailurus'' was a likely ancestor of ''Pseudaelurus'', which lived 20-10 million years ago, and probably gave rise to the major felid lines, including the extinct machairodontines and the extant felines and pantherines, although the phylogeny of the cats is still not precisely known. ==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「Proailurus」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.
