 That’s what it wants to hear, because that sound is gonna mean that’s where lunch is. 

 
A battle with Triceratops is more often than not a fight to the death. This herbivore has evolved into a tank.
 
Now, as a Tyrannosaur specialist, I don’t like to admit this, but in that situation, a Triceratops probably won, and it probably won on a regular basis. 
 
It looks as if this battle will end in a draw. The barbarian1 of the Cretaceous walks away empty-handed. Because T-Rex are warm-blooded, they need to maintain their body temperature. This means consuming huge amounts of energy, over a million calories every week. That’s nearly 700 kilograms of raw meat needed from a good number of kills. But there could be another way for T-Rex to get his meals, probably by stealing a kill from a rival carnivore.
 
The reality is this has got all the tools of a predator2, and those tools of a predator serve a scavenger3 equally well. 
 
One of those tools is its nose, the most sensitive found on any carnivorous dinosaur4
 
I can tell you that that good sense of smell was awesome5 for finding carcasses. And when it did, it ate those carcasses. 
 
A dead Triceratops. For Tyrannosaurus Rex, scavenging comes with substantial risk. Muscling in on another creature’s kill is not for the faint-hearted. But a T-Rex can take on almost any other meat eater, even another T-Rex. And when it’s Tyrannosaur versus6 Tyrannosaur, the winner takes all. 
 
Cannibalism7 in nature doesn’t seem to be a matter of pleasure. It’s a matter of business. 
 
T-Rex meat is T-Rex food as well, you know. It’s protein.
