Non-stop eating for this gentle giant of Eocene mangrove swamps.
Type: Mammal
Size: 1.8m high at the shoulder
Diet: Herbivore
Predators: Creodonts
Lived: Late Eocene and early Oligocene, from 36 to 30 million years ago.
Arsinoitherium's most distinctive feature was the two large horns on their snouts. The horns were hollow and possibly used to produce loud mating calls as well as to compete with rival males. Arsinoitherium was a hefty creature with thick, hairless skin resembling elephant hide.
Arsinoitherium was very selective in the types of fruit and leaves it ate. Its size meant it had to eat a lot of food - it probably spent much of its day chewing on something.
Arsinoitherium lived in small groups and would have been in the water most of the time. It couldn't straighten its legs, suggesting they were better for wading and swimming than for walking. Its large size kept it safe from most predators, although creodonts might tackle a young Arsinoitherium.

回到恐龙时代：素食主义者--重脚兽
始新世红树林沼泽中嘴巴停不住的温顺巨型动物
门类：哺乳动物
尺寸：到肩部为1.8米高
食性：草食
天敌：古肉食哺乳动物类
时代：始新世末期和渐新世早期，距今3600万至3000万年
重脚兽最有特色的就是它嘴边的两个角。这两个角都是空心的，可能是为了产生洪亮的交配鸣叫，也可能是为了和同性对抗时振奋士气。重脚兽是一种肌肉发达的动物，拥有厚实、无毛的皮肤，和大象的皮差不多。
重脚兽对于使用的水果和树叶的种类十分挑剔。它的体型意味着它需要摄入大量的食物--它可能会花很多时间用来咀嚼食物。
重脚兽小群居住，大多数时间都在水中。它们的腿不能伸直，所以它们选择涉水或是游泳，多过于行走。它庞大的身躯抵挡了大多数掠食者，但是古肉食哺乳动物还是会猎食年幼的重脚兽。
