Description edit
Jumping on its hind legs, the 15–20-centimetre (5.9–7.9 in) long (without tail)[2] 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.[3] A 2019 study confirmed that Argyrolagus was probably adapted for bipedal jumping and was probably also well adapted for digging.[4]
