Cramauchenia is an extinct genus member of the litoptern order of South American mammals. Cramauchenia was named by Florentino Ameghino.[1] The name has no literal translation. Instead, it is an anagram of the name of a related genus Macrauchenia. This genus was initially discovered in the Sarmiento Formation in the Chubut Province, in Argentina, and later it was found in the Chichinales Formation in the Río Negro Province and the Cerro Bandera Formation in Neuquén, also in Argentina, in sediments assigned to the SALMA Colhuehuapian (in the Early Miocene).[2] In 1981 Soria made C. insolita a junior synonym of C. normalis.[3] A specimen of C. normalis was described in 2010 from Cabeza Blanca (Chubut, Argentina) in the Sarmiento Formation, in sediments assigned to the Deseadan SALMA(Upper Oligocene).[4]
