Piceoerpeton : ウィキペディア英語版 | Piceoerpeton
''Piceoerpeton'' is an extinct genus of prehistoric amphibian, containing species known from the latest Cretaceous (late Maastrichtian), Paleocene and Eocene of North America. It is one of the largest known salamanders, and would have approached the cryptobranchid ''Andrias'' in size. However, ''Piceoerpeton'' is unrelated to the Cryptobranchidae; instead it appears to be a member of the extinct family Scapherpetontidae. ==Species== ''P. naylori'' is the smaller, earlier species, being found in Maastrichtian to early Paleocene strata of Wyoming and Montana. ''P. willwoodense'' is the larger, younger species, being found in late Paleocene strata of the Western Interior, and early Eocene strata of the Canadian Arctic.
