a mid-sized species of "simosthenurus", known as 'short-faced' kangaroos, one of several genera in a macropodid lineage that diversified in pliocene australia. the mass of adults is estimated to have around 118 kilograms, standing at a similar height to larger modern roos but with a heavier and more robust body. the dentition contains molars set close to the jaw, which combined with the cranial structure, strongly indicates an animal capable of consuming tough vegetation. the short jaw and facial anatomy clearly distinguishes their appearance from the surviving lineage of kangaroos, which usually graze on grasses rather than a browsing diet, and more closely resembles the habits of the modern koala "phascolarctos cinereus".
