Goodfellow's Tree Kangaroo Dendrolagus goodfellowi

They are native to the rainforests of New Guinea. Goodfellow's tree-kangaroos are slow and clumsy on the ground, moving at about walking pace and hopping awkwardly, leaning their bodies far forward to balance the heavy tail. However, in trees they are bold and agile. They climb by wrapping the forelimbs around the trunk of a tree and hopping with the powerful hind legs, allowing their forelimbs to slide. They have extraordinary jumping ability and have been known to jump to the ground from heights of 9 metres (30 ft) without harm.

They really are! They don't have an inaturalist page so I'll use the wikimedia commons photos.

Protemnodon viator was a large macropod that lived in what is now western and southern Australia during the late Pleistocene, around 50,000 years ago.

Although it was built more like a giant wallaby, ancient mitochondrial DNA has shown that its closest living relatives are actually modern grey kangaroos.

Estimated to have weighed about 170kg (~375lbs) – twice as much as the largest modern red kangaroos – it would have stood up to 2.4m tall (~8') on its hind legs. But unlike its living relatives Protemnodon's limb proportions indicate it wasn't a very efficient bipedal hopper, instead probably mostly moving with a bounding or galloping quadrupedal gait.

Its forelimb anatomy also suggests it was a good digger, and strongly curved claws on its hind feet may have helped provide grip on uneven ground.

It should be pretty easy to figure out where tree kangaroos spend most of their time! Although they are true kangaroos, just like its bigger and more famous cousins, members of the genus Dendrolagus have evolved for an arboral life, which include a larger tail for balance and longer hind feet to better climb trees with. Because of these adaptations, tree kangaroos are capable of leaping over 60 ft (18 m) from the tree tops to the ground!
