（单词翻译）
Triceratops is an amazing animal simply because it was absolutely enormous. They had this big massive body with a big gut1. So, you know, we are talking of an animal that’s maybe four or five tons.
A Triceratops is half as tall as a T-Rex, yet it weights about same. The difference is how that weight is distributed.
Its back legs are straight, like a
rhino2. Its front legs splay out like a
lizard3. This design pushes its centre of gravity towards its head, which weights half a ton. Therefore, when a Triceratops stands on its ground, it’s rock-solid, built for a direct frontal attack. This powerful head and shoulders protect a body covered in a hide so soft a T-Rex could slice right through it.
Triceratops had this wonderful, protective thing on the front of its head. It’s got a frill that protects its neck, one of the most vulnerable places on the animal.
The frill is solid bone, six times thicker than a human
skull4. To foil an opponent, it’s strongest at the edges. This frill forms an almost impenetrable shield, one able to
repel5 the most powerful
jaws6 the earth has ever known.
The frill, the bone over the neck, is that thick. It’s in several layers. And it's a composite armor. On top would be a thick layer of fingernail-like skin, almost impossible to bite through.
This four-legged monster is well-protected and dangerous.
Triceratops is heavily armed, and heavily armored and can kill you.
For a Triceratops, power is everything.
