Ctenochasmatidae is a group of pterosaurs within the suborder Pterodactyloidea. The earliest known ctenochasmatid remains date to the Late Jurassic Kimmeridgian age. Previously, a fossil jaw recovered from the Middle Jurassic Stonesfield Slate formation in the United Kingdom, was considered the oldest known. This specimen supposedly represented a member of the family Ctenochasmatidae,〔Buffetaut, E. and Jeffrey, P. (2012). "A ctenochasmatid pterosaur from the Stonesfield Slate (Bathonian, Middle Jurassic) of Oxfordshire, England." ''Geological Magazine'', (advance online publication) 〕 though further examination suggested it actually belonged to a teleosaurid stem-crocodilian instead of a pterosaur. ==Classification== Cladogram following Andres, Clark & Xu, 2014.〔 }} }} }} }} |label2= Ctenochasmatinae |2= }} }} }} }} 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「Ctenochasmatidae」の詳細全文を読む スポンサード リンク
