Distribution

Dusicyon cultridens is only known from fossil remains in Argentina. It lived in the Late Pliocene (Uquian in the SALMA classification), from approximately 2.8 to 2.6 million years ago. It was around at about the same time as the rodent Akodon lorenzinii. The fossils were found at cliffs near the Atlantic Ocean, in what is now the coastline of the province of Buenos Aires.[2]

Habitat and characteristics

Dusicyon cultridens lived in the South American temperate grasslands (pampas). Its size was between that of existing species such as the pampas fox and South American gray fox.
