And this well-protected herbivore is everywhere. In fact in the Late Cretaceous, Triceratops outnumbered Tyrannosaurs ten to one. Their success is down to one reason. 

 

A single thrust of the brow horn could penetrate right into the cardiac chamber or the lungs. 

 

If you’re gonna put a meter-long horn into a chest cavity of a T-Rex, the chance of you doing some damage are pretty great.

 

Tyrannosaurus Rex is stabbed in the eye. 

 

The key element for any predator is to go in, make the kill, get what they need, and do it without injuring himself.

 

For a carnivorous predator, losing an eye could be fatal. Back at the nest, the chicks are guarded only by the male. Over him, a Quetzalcoatlus senses blood. On the ground, one parent is down and the other faces starvation. For a vulnerable baby T-Rex, the situation couldn’t get much worse.

 

Sauroposeidon is the tallest land animal of all time. At 17 meters high and 30 meters long, it would dwarf any living creature today. But despite these mammoth proportions, its brain is tiny, weighting just over 100 grams. 

 

The brain size of Sauroposeidon would probably be about the size of a cheeseburger. 

 

It probably had the smallest brain size to body size of any big animal that’s ever lived.

 

Big, dumb, brute. 

 

A Sauroposeidon’s brain is a thousand times smaller than its body, just 1/8 of the brain capacity of a T-Rex. And its cerebrum, where strategic thinking takes place, is barely developed.
