Extinction, When Did Arsinoitherium Die Out

The habitat of Arsinoitherium was disrupted by significant climate change that occurred in the Late Eocene. The temperature changed from being hot to being much more chilly. Due to this, their moist forested environment was lost, and grasslands and savannas began to grow. A few of these mammals survived still and began to change habitats, looking for other parts of the continent that were still warm and had enough food for them. However, by the Middle Oligocene, these animals could no longer move around as much, as most of their food sources had been destroyed. Consequently, they went extinct shortly after this period.
