英語(yǔ)聽(tīng)力：美洲大平原-12

Because these two bull mammoths both had broken tusks, 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 fatality. Beneath one mammoth's shoulder blade was the skull 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 decomposing 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 prey can be more trouble than large dead ones. Prairie dogs are always on alert and once a trespasser is spotted, the entire town vanishes into thin air.

Prairie dogs aren't really dogs at all. They're rodents but coyotes are full-blooded members of the canine clan 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.
