Perfect skeletons of large toads 

 (Latonia seyfriedi, v. Meyer; Pelophilus 

 mjassizi, Tschudi) are known from the 

 Miocene freshwater marls of Oeningen, 

 Baden. The equivalent deposits of Giinzburg, Sansan, and Sinigaglia likewise 

 yield remains of tailless Batrachians. Pleistocene Auura, like late Tertiary 

 Urodeles, belong exclusively to recent genera.
