Trionychiais asuperfamilyofturtleswhich encompasses thespeciesthat are commonly referred to as softshelled turtles as well as some others. The group contains two families,Carettochelyidae,which has only one living species, thepig-nosed turtle(Carettochelys insculpta) native to New Guinea and Northern Australia, andTrionychidae,the softshelled turtles, containing numerous species native to Asia, North America and Africa. These families likely diverged during the late Jurassic.[2]The oldest known stem-trionychian isSinaspideretesfrom the Late Jurassic of China.[3][4]
