The thylacoleo is an extinct genus of carnivorous marsupials that lived in australia from pléistocène to the late pléistocène (2million to 46 thousand years ago). He were the largest mammalian predators in australia of that time. The estimated average weight for the species (thylacoleo carnifex) ranges from 101 to 130kg
Thylacoleo are capable of pinning down flyers in mid-flight (anything but the Quetz and Wyvern, I believe), other Thylacoleo, and even Therizinos. You can also jump from object to object by holding down the jump button while pouncing from a tree or cliff (have to hit it at the right angle, however). Upvote to inform others!
