Extinct 'Giant Wallaby' Kangaroo Primarily Used Four Legs, New Study Finds

Research reveals Protemnodon, a large Pleistocene kangaroo, moved quadrupedally, challenging previous assumptions of hopping.

Protemnodon, an extinct kangaroo species, lived around 2.5 million to 10,000 years ago.
New findings indicate this species was mainly quadrupedal, unlike modern kangaroos.
The study analyzed limb proportions and anatomical features to determine locomotion.
Previous assumptions that Protemnodon hopped were based on its size, now disproven.
This research suggests a diverse range of habitats in ancient Australia.
