- It was 8 metres long and 4.8 metres at the shoulders
- It weighed 20 metric tons
- Its skull was over 2 metres long
- It had a long neck for browsing leaves from trees
- It lived in Asia during the Oligocene
- Its extinction in the early Miocene might be due to mastodonts arriving from Africa, followed by their predators Amphicyon and Hyainoilourus.
