Ekaltadeta ima

Ekaltadeta ima

Also known as Killer Rat-kangaroo, Carnivorous Rat-kangaroo

Ekaltadeta ima roamed the dense, lush rainforests of ancient northern Australia as a robust, predatory relative of modern rat-kangaroos. Equipped with powerful jaws and a distinctive serrated, buzz-saw cheek tooth, it likely crushed bone, sliced through flesh, and cracked tough invertebrates with ease. Unlike its gentle grazing modern kin, this forest-floor dweller relied on a bounding gait to stalk small vertebrates across prehistoric Riversleigh.
