Deuterotherium is an extinct genus of South American native ungulates, which lived during the Deseadan age of the Oligocene in what is now Argentina. Its type species is Deuterotherium distichum.[1] It was named by Florentino Ameghino in 1895.[1] The holotype of Deuterotherium distichum is a calcaneum.[2] It was formerly identified as a proterotheriid litoptern.[1] In 1999, Shockey argued Deuterotherium was certainly not a litoptern and interpreted it as a notohippid notoungulate.[2] In research by Soria posthumously[2] published in 2001, Soria considered Deuterotherium a nomen dubium.[3]
