The only way to deal with this huge, curved, cantilevered, composite armor is a crushing blow with multiple teeth.

For a T. Rex, the key to defeating a Triceratops is his huge jaws⁵, driven by two sets of powerful muscles.

对于雷克斯霸王龙而言，击倒三角龙的关键是它的巨颚，这个巨颚由两组强韧的肌肉牵引。

第一组肌肉从头骨顶部贯穿到下颚缘。

These muscles give this carnivore's bite its speed.

这组肌肉保证撕咬的速度。

wrap around the lower jaw, tying it to the roof of the mouth.

将其与上颚后部相连。

They give T. Rex's bite its 3 tons of force, twice the biting power of a great white shark.

这组肌肉产生出3吨的咬力，是大白鲨咬力的两倍。

And not only that. Just like a python, T. Rex can dislocate its jaw.

不仅如此。与巨蟒一样，雷克斯霸王龙能脱解两颚。

Cranial kinesis is basically the ability to swallow things larger than your own head.

颅骨运动，从根本上说就是能吞下比头大的食物。

That's because the skull expands as it opens up.

因为颅骨打开后，吞食空间随即扩大。
