What is the closest living relative of the extinct Mastodon?
The Mastodon, also , and more commonly, known as the "Mammut" is thought to have become extinct during rapid climate change. More advanced tools - which would have allowed hunters to chase and kill them- may also have been responsible for their dwindling numbers.
With shorter legs than mammoths and a longer, more muscular body, it was most closely related to an Asian elephant. The males were larger than the females.
Mammuts lived in herds, such as elephants but had a different habitat, living in forested areas and were browsers and grazers. Elephants, themselves, are only grazers. Browsers eat mostly leavers and grazers grass.
