Triceratops is an amazing animal simply because it was absolutely enormous. They had this big massive body with a big gut 1. 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 rhino 2. Its front legs splay out like a lizard 3. 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 skull 4. To foil an opponent, it’s strongest at the edges. This frill forms an almost impenetrable shield, one able to repel 5 the most powerful jaws 6 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.
