''Epicyon'' ("more than a dog") is a large, extinct, canid genus of the subfamily Borophaginae ("bone-crushing dogs"), native to North America. Epicyon existed for about from the Hemingfordian age of the Early Miocene to the Hemphillian of the Late Miocene.〔(PaleoBiology Database: Epicyon )〕 Epicyon, which was about 5 feet long, had an estimated weight of 150 pounds.〔http://dinosaurs.about.com/od/mesozoicmammals/p/epicyon.htm〕 Epicyon had a massive head and powerful jaws, giving its skull a lion-like shape rather than that of a wolf. ''Epicyon'' was one of the last of the Borophaginae and shared its North American habitat with other canids: * ''Borophagus'' (mya) * ''Epicyon'' from 20.6 to * ''Carpocyon'' from 20.4 to * ''Paratomarctus'' from 16.3 to * ''Aelurodon'' from 15.97 to * ''Canis lepophagus'' from 10.3 to ''Canis lepophagus'' may be the ancestor to the wolf. ==Taxonomy== ''Epicyon'' was named by Joseph Leidy in 1858 as a subgenus of Canis. It was also mentioned as belonging to ''Aelurodontina'' by William Diller Matthew & Stirton in 1930. 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「Epicyon」の詳細全文を読む スポンサード リンク
