This creature lived 30,000 years ago when humans didn't exist. The korogonissaur evolved over the years to have greater speed and agility . It's one third wolf, one third kangaroo and one third squirrel anatomy makes it perfect for grassland and for speed. The korogonissaur is a widespread animal preying on elk, dodos, wolfs and small horses. Like the allosaurus it produces all the bite power from its powerful neck. It's kangaroo legs are good for speed when chasing elk, wolves and horses and the legs are good also for jumping. This adaptation is helpful when attacking things bigger than them like bison and Mammoths although they would only attack Mammoths if blood thirsty . This creature died out after thriving here for 100,000 years before humans came.
The arrival of humans affected this creacher in two ways. One is that the humans were killing all the elk and horses so they didn't have much to eat. Secondly is that the humans were chopping trees down so there was no shelter from the scorching sun and when you're really hot you feel listless so the korogonissaur could not really hunt and since humans killed all the elk and horses they had to adventure out further in search of food but they would be too tied so like the megalodon it died from starvation.
