Leaping to Extinction?

Before humans reached that continent, Australian fauna (animals) were even stranger. Scientists have now identified 3 new species of extinct megafauna (really big animals). Currently, the largest was Protemnodon viator, a kangaroo-like animal, weighing about 170 kg. This beast was, consequently, twice the size of extant (alive today) kangaroos (https://www.theguardian.com/australia-news/2024/apr/15/giant-fossil-kangaroos-scientists-identify-three-new-species-of-extinct-megafauna). It seems likely that Protemnodon viator generally operated on four legs, only rarely hopping (perhaps to evade predators?). These big marsupials may have became extinct, as a consequence of climate change events. So, climate change isn't an exactly 'new' event and has dramatic consequences!
