Didolodus

Didolodus is an extinct genus of mammal. It is classified as a condylarth[citation needed], but used to be associated with arctocyonians and litopterns. Its remains were found in Patagonia.

Didolodus was a quick-footed creature which probably lived like early ungulates such as Propalaeotherium, based on its highly similar teeth. It was around 60 centimetres (2.0 ft) in length, with short limbs and a long tail.
