The giant kangaroos are from the genus Protemnodon, and would have demonstrated more variability in shape, range and hopping method than researchers previously thought, according to a statement from Flinders University in South Australia., is based on the discovery of several complete fossil skeletons by paleontologists working in Lake Callabonna in southern Australia.
One species – P. viator – would have weighed up to 170 kilograms , making it around twice as heavy as the largest male red kangaroos living today. Its name, “viator,” means traveler or wayfarer in Latin, and Kerr told CNN that the kangaroos would probably have moved in large groups known as “mobs,” as red and grey kangaroos do today.
Comparatively less is known about P. dawsonae because there are fewer fossils for scientists to study, but it was probably a “mid-speed hopper,” the researchers said. This extinction, however, did not affect similar animals such as wallaroos and grey kangaroos, for reasons scientists do not fully understand.
