 T-Rex is impressive and it's powerful, but compare to Ankylosaurus, it is relatively¹ lightly built. Protective plates made of bone and cartilage covered this lumbering² creature from head to tail. Light, but extremely strong, the hide of Ankylosaurus is built like a bullet-proof vest. And most importantly, Ankylosaurus is armed with a deadly weapon, a bony club. 

 

If that club were to connect into the skull³ of the T-Rex, or into the shin and foot of the T. Rex, it would shatter those bones. 

 

I think that one good blow by the tail club would be enough to deter⁴ this Tyrannosaurus.

 

Ankylosaurus are plant-eaters, but they are designed to kill. Even a Tyrannosaurus Rex would struggle to bring one down. 

 

T-Rex has a refined array of senses, including an acute sense of smell that should lead it straight to the meal. Behind the nostrils⁵ are large cavernous chambers⁶ lined with sheets of sensory⁷ tissue able to detect odors. The olfactory⁸ bulbs transmit that information back to the brain. 

 

One of the big surprises was the size of the olfactory bulbs, part of the brain associated with processing information about smells in the environment.

 

To increase the number of odor detectors⁹, the area containing sensory tissue is designed like a radiator¹⁰.

 

A T-Rex could pick up even the slightest scent¹¹ of meat and from a long distance. 

 

T-Rex had a sense of smell equivalent to 100 bloodhounds all duct-taped together.

 

They certainly had the largest olfactory lobe¹² of any animal, living or extinct, on this planet. 

 

This is a vital tool for a hunter. From a substantial distance, a T-Rex can hold in on prey¹³ or pick up their hatchlings' distinct scent.
