 Deinonychus instinctively¹ knows to go for this giant’s weak spot, its neck.

 

You’ve got the windpipe there. You’ve got the jugular² vein³, which if opened up will mean that that Sauroposeidon is dead meat. 

 

But death does not come quickly or pleasantly. For a pack of Deinonychus, a kill this big means a feast. And their skulls⁴ are specially⁵ designed for competitive eating. Its jaws⁶ are narrow and lightly built. And its gums are equipped with 70 sharp, serrated teeth. They’re like walking piranhas, perfect at eviscerating⁷ a victim. 

 

If you look at the teeth carefully, they’re ridiculously small. They are very, very delicate. They’re not killing⁸ weapons. 

 

A single adolescent Sauroposeidon, an animal more than 10 times the size of its killer⁹ can feed a pack of hungry Deinonychus for weeks, making the kill worth the effort and the risk. 

 

Texas, 68 million years ago, here death comes not only from well-armed gargantuan¹⁰ dinosaurs¹¹, sometime it swoops¹² down from the sky on the wings of a flying reptile¹³, Quetzalcoatlus. 

 

A Quetzalcoatlus could be kind of seen as a Cretaceous stealth bomber¹⁴, air-to-ground weaponry at its finest. 

 

They weren’t big, fragile kites. They were big, mean, terrifying bats from hell.

 

Quetzalcoatlus is arguably the largest, most sophisticated animal ever to fly. A wingspan of almost 12 meters holds aloft a body weighing 180 kilograms.
