 Though very powerful, she’s not a sprinter¹ and she needs to get close to her prey² before she strikes. 

 

This time she’s run too soon and it’s a fruitless chase. 

 

Then her attention is diverted to a slower-moving target, slow but not defenseless. She backs off and tries a different approach. 

 

There’s obviously a meal in there, but how to get to it? 

 

She homes in on the head and bites straight through the skull³. The glyptodont is dead, but the jaguar⁴ still goes hungry. Unable to crack her victim’s tough armor, all she manages to walk away with is a bony scute. The jaguar will vanish in North America. And glyptodonts, like many Ice Age beasts, become extinct. But at the bottom of the spring, one tiny fragment of an Ice Age giant will remain undisturbed for 13,000 years, while above it, the landscape of Florida will change forever.
