Temporal range: during the Late Oligocene to the Miocene (Australia, Northern Queensland)
Dimensions:weight - 5-10 kg
A typical representative: Ekaltadeta ima
Ekaltadeta ima is an extinct species of rat-kangaroo from the family Hypsiprymnodontidae, which also contains the extant Musky rat-kangaroo, Hypsiprymnodon moschatus. It was nicknamed the “killer kangaroo”, due to its enlarged premolar which enabled it to eat flesh, but it was most likely omnivorous. Fossil remains suggest it may have stabbed at its prey with elongated teeth in the lower jaw, and manipulated and held its victims with its front legs.
