Didolodontidae Explained

Didolodontidae is a possibly paraphyletic family of "condylarth" mammals known from the Paleogene of South America,^{[1] [2]} 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.^[3] They range in age from the early Paleocene (Selandian/Peligran) to late Eocene (Priabonian/Mustersan). The attribution of Salladolodus deuterotheroides from the Late Oligocene of Bolivia to the family is doubtful.^[4]
