Ambulator keanei
Preserved impressions of the feet of Ambulator show that it had evolved many adaptations for moving its 250-kilogram body long distances. Its legs were held straight under the body like columns, and its feet had large, cushioned pads. This was an animal that had given up climbing to find new food or water sources.
Kolopsis torus
Kolopsis was larger than any modern marsupial at over 150 kilograms. Fossil evidence shows adaptations for walking instead of climbing. But Kolopsis was still pretty ‘handy’ and may have been able to scratch and scrape open logs or dig for fungi.
Nototherium inerme
A true giant, Nototherium may have weighed well over one tonne. It had a very short face with wide cheek bones. This made its jaws very strong, perfect for browsing on tough grasses and sedges.
Zygomaturus trilobus
Zygomaturus weighed over 900 kilograms. It had a huge head with large cheeks and an upturned nose. The name Zygomaturus refers to its giant cheekbones, or zygomatic arches. Scientists once wondered if it had small horns on its nose, but recent research found no evidence for these, which is good – the head is bizarre enough already!
