''Pangerpeton'' is an extinct genus of salamanders. Its monotypic species is ''Pangerpeton sinensis''. ''Pangerpeton'' is a metamorphosed, primitive salamander from the Late Jurassic Daohugou fossil bed near Wubaiding Village of Lingyuan City, Liaoning Province, China. Yuan Wang and Susan E. Evans (2006)〔Wang, Y., Evans, S. E., 2006. A new short-bodied salamander from the Upper Jurassic/Lower Cretaceous of China. Acta Palaeontologica Polonica, 51(1):127~130.〕 named this new taxon with a phylogenetic analysis of caudates at familial level including fossil taxa, such as ''Marmorerpeton'', ''Karaurus'', ''Jeholotriton'', ''Chunerpeton'', ''Liaoxitriton'', ''Iridotriton'', and ''Valdotriton''. The analysis placed ''Pangerpeton'' as a sister taxon to ''Jeholotriton'' from the equivalent fossil bed, and the two are close to the base of crown−group Urodela either just outside it or just within. This Jurassic amphibian is characterized by its short trunk (only 14 presacrals) and short and wide head, giving a fat body shape, from which the genus name was derived ("Pang" means fat in Chinese). ==See also== * Prehistoric amphibian * List of prehistoric amphibians 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「Pangerpeton」の詳細全文を読む スポンサード リンク
