Description

Jumping on its hind legs, the {{convert|15-20|cm|in|adj=on|abbr=}} long (without tail){{Cite book|title=新版 絶滅哺乳類図鑑|publisher=Yukimitsu Tomida|date=30 January 2011}} 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.{{cite book |editor=Palmer, D.|year=1999 |title= The Marshall Illustrated Encyclopedia of Dinosaurs and Prehistoric Animals|publisher= Marshall Editions|location=London|page= 203|isbn= 1-84028-152-9}} A 2019 study confirmed that Argyrolagus was probably adapted for bipedal jumping and was probably also well adapted for digging.{{cite journal |last1=Abello |first1=María Alejandra |last2=Candela |first2=Adriana Magdalena |title=Paleobiology of Argyrolagus (Marsupialia, Argyrolagidae): an astonishing case of bipedalism among South American mammals |journal=Journal of Mammalian Evolution |date=2020 |volume=27 |issue=3 |pages=419–444 |doi=10.1007/s10914-019-09470-z|s2cid=254693227 |url=http://sedici.unlp.edu.ar/handle/10915/139716 }}
