''Germanosaurus'', meaning "German Kingdom of Prussia lizard", is an extinct aquatic genus of nothosaurid sauropterygian known from the early Middle Triassic (early Anisian stage) Lower Muschelkalk of what was known as Upper Silesia, now a part of Poland. The type species of ''Germanosaurus'' is ''G. latissimus'', originally named as a species of ''Nothosaurus''. After a new generic name was erected for it, the holotype fragmentary skull was lost, possibly during WWII. Rieppel (1997) thus considered the species to be a ''nomen dubium'' in the species. However from surviving illustrations and descriptions of the material, he concluded that another taxon known as ''Cymatosaurus schafferi'', is referable to ''Germanosaurus'' and possibly even represents the same species as ''G. latissimus''. Rieppel removed the species from ''Cymatosaurus'' and created the new combination ''G. schafferi'', making it the only valid species of ''Germanosaurus'' diagnosable to the species level. All known material of ''G. schafferi'', including the holotype skull, were collected from the same general locality as the holotype skull of ''G. latissimus'', at Sacrau now Zakrzów Turawski, near Goglin, Gorny Slask of Poland. These deposits belong to the lower part of the Goglin Formation, which is a basal part of the Lower Muschelkalk, dating to the early Anisian stage of the early Middle Triassic, about 247 million years ago.〔 ==References==
