The apex mammalian carnivore of this ecosystem is a mesungulatid meridiolestidan; mostly specialised towards herbivory, several lineages turned to more carnivorous lifestyles in the Palaeogene, with virtually no other large mammalian carnivores in Gondwanna at the time. Kuzcotherium elegans in particular seems to form a clade with Allqu uyam, likely representing an old low latitude mesungulatid clade that turned towards more carnivorous niches as herbivores from north and south invaded the region. Turning competition into food was a brilliant move, and thus this cougar-sized animal was capable of living like our big cats and fossa, using its powerful jaws and clawed forelimbs to bring down most of the megafaunal herbivores it co-existed with (aside from adult Baroauchenia canifacis, far too large), though it likely prefered small to mid-sized prey like the ferugliotheriids and smaller Glyptoguy species. It differs from our timeline's sparassodont metatherians by adopting a more cat-like build, thus relying more on the forelimbs than the jaws. This offered it a degree of versality, but time will tell if it will pay off, as it was still a hypercarnivore after all, now incapable of turning to plants like its ancestors did.
