Didolodontidae
Didolodontidae is a possibly paraphyletic family of "condylarth" mammals known from the Paleogene of South America, with most specimens known from Argentina. They were generally small-medium in body size, and had a bunodont dentition. A close relationship with litopterns has been suggested by some studies. They range in age from the early Paleocene to late Eocene. The attribution of Salladolodus deuterotheroides from the Late Oligocene of Bolivia to the family is doubtful.
