Batrachosauroididae

Remarks. — Batrachosauroididae are an extinct family of neotenic salamanders reliably known by isolated bones and rare skeletons from the Aptian / Albian – late Miocene of North America, the Campanian – late Miocene of Europe, and, potentially, back into the Bathonian – Berriasian of Europe (e. g., Auffenberg 1958; Estes 1969 a, 1981; Naylor 1981: table 1; Duffaud 1995; Milner 2000; Evans and McGowan 2002; Holman 2006; Oreska et al. 2013; Vasilyan and Yanenko 2020). The family contains six named genera (e. g., Estes 1981; Naylor 1981; Denton and O’Neill 1998; Milner 2000; Vasilyan and Yanenko 2020): Batrachosauroides Taylor and Hesse, 1943 (two species: early Eocene – middle Miocene, southern and western USA); Opisthotriton Auffenberg, 1961 (one species: middle / late Santonian – late Paleocene) and Prodesmodon Estes, 1964 (one species: middle / late Campanian – early Paleocene), both in the North America Western Interior; Peratosauroides Naylor in Estes, 1981 (one species: late Miocene, California, USA); Parrisia Denton and O’Neill, 1998 (one species: Campanian, New Jersey, USA); and Palaeoproteus Herre, 1935 (three species: late Paleocene – early Miocene, Austria, France, Germany, and Ukraine).
