（单词翻译）

 Because these two bull mammoths both had broken tusks1, they could have fought at closer quarters than they would do normally. Twisting and turning, they became locked in a deadly embrace. Even more bizarre, this twist of fate then caused a third fatality2. Beneath one mammoth's shoulder blade was the skull3 of a coyote, pressed into the ground. 

 
While we can only speculate on just how the coyote died, it's likely it was scavenging around the decomposing4 carcasses, when one caved in and crushed it. 
 
Coyotes are still on the plains today. They hunt their food as well as scavenge carcasses,but small live prey5 can be more trouble than large dead ones. Prairie dogs are always on alert and once a trespasser6 is spotted7, the entire town vanishes into thin air. 
 
Prairie dogs aren't really dogs at all. They're rodents8 but coyotes are full-blooded members of the canine9 clan10 and like all dogs, they sometimes hunt in groups to tackle bigger prey. Some prey, however, are just too big, even for a pack of coyotes. 
 
But 13,000 years ago, there was another kind of canine hunter here, one that gave even the bison a run for their money. The wolf -- the ultimate pack hunter.
