It was first constructed by Charles William Andrews in 1913 to include just one member: ''Hylaeochampsa''. However, a new genus named ''Iharkutosuchus'' was described in 2007 and was found to be a sister taxon of ''Hylaeochampsa'', and thus a member of the family Hylaeochampsidae. The genus ''Heterosuchus'', named in 1887, may also be a member of the family. However, it is likely to be synonymous with ''Hylaeochampsa'' and has been considered a ''nomen dubium'' by James M. Clark and Mark Norell. Clark and Norell also claimed that there is no evidence to suggest that the two genera form a true clade distinct from other eusuchians, because remains associated with ''Heterosuchus'' are to fragmentary to show any clear phylogenetic relationship.〔 A fourth genus called ''Pietraroiasuchus'' was assigned to Hylaeochampsidae in 2011. A phylogenetic analysis conducted with the description of ''Pietraroiasuchus'' also found ''Pachycheilosuchus'' to be part of the family. The family existed during the Cretaceous period in what is now Europe. ''Hylaeochampsa'' and its possible synonym ''Heterosuchus'' have both been found from the Vectis Formation of the Isle of Wight in England, dating back to the Barremian stage of the Early Cretaceous. Specimens of ''Iharkutosuchus'' have been found from the Csehbánya Formation in western Hungary, which was deposited during the Santonian stage of the Late Cretaceous. All hylaeochampsids had highly brevirostrine snouts and exhibited heterodonty, with large teeth concentrated posteriorly that were most likely adapted to crushing. In ''Iharkutosuchus'' these teeth were even multicusped. This is often characteristic of mammals but is highly unusual for a crocodylomorph, and suggests that the animal may have been herbivorous. ==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「Hylaeochampsidae」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.
