Andrias scheuchzeri is a species of giant salamander from the Oligocene to the Miocene period of Switzerland. It is an extinct member of the same genus that includes both the Chinese and Japanese giant salamanders, two of the largest amphibians in modern times. A debate is currently going on as to wether or not this species is actually the same as the modern Chinese giant salamander, which would mean that the species isn't actually extinct. When it was first discovered, it was originally thought to be a mutilated human child, but it was later determined to actually be a salamander.
