Giant prehistoric kangaroos preferred to ‘chill at home’ and didn’t like to go out much, scientists say

These massive prehistoric kangaroos, known as Protemnodon, roamed Australia 5 million to 40,000 years ago. Though significantly larger than modern relatives, they were "homebodies," sticking close to their habitats rather than spreading out. This behavior made them vulnerable during a climate shift that disrupted their rainforest environment about 280,000 years ago. Researchers used chemical signatures from fossils and geology to determine their range and survival strategies, revealing how their restricted habitat choices contributed to extinction in the face of environmental change.
