Jumping on its hind legs, the long (without tail) Argyrolagus resembled a gerbil or kultarr. It had a long tail for balance, and a narrow head with a pointed snout. Judging from its huge eyes, Argyrolagus was nocturnal. The form of its teeth suggest that it would have fed on desert plants. A 2019 study confirmed that Argyrolagus was probably adapted for bipedal jumping and was probably also well adapted for digging.
