英语听力：2013-04-07 恐龙之战之极限生存 Extreme Survivors—9

 And there is something else unusual about a T-Rex’s nose. The nostrils¹ are a huge 25 centimeters apart, which means T-Rex can smell in stereo. It can triangulate an odor and pinpoint² its exact source. 

 

T-Rex could walk into a crowded auditorium³ and in a few seconds identify every single person and creature by its own idiosyncratic odors.

 

This female, desperate to eat, picks up the scent⁴ of a meal, but it’s the scent of an animal that even the strongest Tyrannosaurus prefers not the tackle.

 

(That’s) the most dangerous challenge that any big carnivore ever faced, was the swinging head of Triceratops. It’s like a gigantic white rhinoceros⁵ on steroids. 

 

At eight meters long and three meters tall, a fully⁶ grown Triceratops can reach six tons in weight.

 

If there’s an animal whose scent would frighten a T-Rex, it’s Triceratops. 

 

T-Rex is well aware of the risks. Its cerebrum has information stored from previous encounters. It knows the danger ahead. Overpowering a Triceratops means tackling a beast with meter-long horns covered in rock-hard keratin and a body protected by a bony shield. But ensuring the survival of her genes⁷ for another generation would be worth a fight.
