Temporal range: Pleistocene–recent
Food and diet
The Chacoan mara eat grasses and other herbage. They will eat nearly any available vegetation.
Chacoan maras live in small groups of up to four animals.
Scientific classfication and relatives
The Chacoan mara is from the family Caviidae, which includes cavies, such as their larger relative the capybara, and guinea pigs. Chacoan maras are closely related to the other member of the Dolichotis genus, the Patagonian mara. Maras are the fourth largest rodent in the world after the capybaras, beavers and porcupines . Though the mara may look like a rabbit, the rabbit is not actually a rodent and therefore not as closely related to the mara as one might expect.
