The weight of the giant lemur is about 50 kilograms, making it one of the largest lemurs in history. It is a slow-moving, bulky creature with a body posture similar to modern koalas. These animals used to inhabit the island of Madagascar. 2300 years ago, humans arrived on the island, causing the species to rapidly decline and eventually become extinct approximately 500 years ago. This skeleton is housed in the Vienna Museum of Natural History.
