侏罗纪搏击俱乐部 第29期:连骨头都不剩下

 　　Their jaws 1 are a little bit different. That's how we tell these two animals apart.

　　它们的双颚也有些不同。这也被用来区分这两种动物。
　　Nanotyrannus has more teeth in its jaws.
　　矮暴龙的嘴里牙齿更多。
　　The teeth are pretty much the same size as the teeth of a baby Tyrannosaurus Rex, still the T-Rex would probably have had a much harder stronger bite than the Nanotyrannus.
　　牙齿和幼年霸王龙的牙齿的大小基本相当，而霸王龙的咬合力可能要比矮暴龙厉害得多。
　　Nanotyrannus teeth are more primitive 2 in design.
　　矮暴龙的牙齿更加原始。
　　They're much more blade-like, very thin.
　　它们更加像刀刃，非常薄。
　　Tyrannosaurus Rex are almost equal side to side as they are front to back.
　　雷克斯暴龙牙齿的宽度和厚度基本差不多。
　　So this means that their feeding habits were different.
　　这意味着它们的进食习惯不一样。
　　Nanotyrannus would strip carcasses of bones, Tyrannosaurus Rex would eat the whole carcass, including the bones.
　　矮暴龙会把尸体吃的只剩骨头，而霸王龙会吃下整个尸体，包括骨头。
　　The life of a predator 3 depends on its ability to hunt and kill game.
　　掠食者的生命要靠它们捕猎杀死猎物的能力。
　　But it also had to defend itself against rivals.
　　不过也要靠它们抵御敌手的能力。
　　Predatory animals have been at war with each other since the beginning of time.
　　掠食性动物从一开始就相互开战。
　　We see it today in animals like lions and hyenas 4.
　　在如今的狮子和鬣狗之间就能看到。
　　Predators 5 don't tolerate other predators in their same environment because they both compete for the same food source.
　　掠食者不能容忍其它掠食者跟它们分享环境，因为它们要争夺相同的食物资源。
　　So any chance they have to kill a rival, they'll take it.
　　所以只要有杀死对手的机会它们就不会放过。
　　An adult Nanotyrannus would had certainly take advantage of an unguarded juvenile 6 because it means getting rid of its competition.
　　一头成年矮暴龙会毫不犹豫地攻击没有防护的幼龙，因为这意味着消灭它的竞争者。
　　Certainly the animals are similarly enough designed, and comparable enough in strength,当然它们的身体设计较为相似，也差不多一样强壮，that we might expect, that the experience of the adult Nano T, would actually allow it to win the day, over the young Tyrannosaurus Rex.
　　我们认为成年的矮暴龙应该更有经验，而能够战胜年轻的雷克斯暴龙。
　　In terms of fighting skills, of course, this adult Nanotyrannus will have had a lot more experiences over its lifetime than this juvenile Tyrannosaurus Rex,要论战斗技巧，这头成年矮暴龙当然在一生中会比年幼的雷克斯暴龙积累了更丰富的经验，so it may have literally 7 years of experience beyond what this other young individual would have had.
　　它可能会比这幼霸王龙多出很多年的经验。
　　In my mind, there is no doubt that Nanotyrannus would have been more than a match for a single juvenile Tyrannosaurus Rex.
　　在我看来，毫无疑问矮暴龙是单独一只幼霸王龙无法匹敌的对手。
　　But the real question for me would be, what would happen if a Nano killed a Rex?
　　不过对我来说，真正的问题是矮暴龙杀死霸王龙后会怎样？
　　Would it eat it or would it just leave it and move on?
　　它会吃了它还是把它扔在那儿不管？
　　After spending energy in a fight, I would suspect that the winner would need to recharge his batteries and take advantage of that food source now lying at his feet.
　　在费力进行战斗之后，我觉得胜利者应该需要补充体力，不会放过脚下的食物来源。
　　Why this Nanotyrannus didn't eat the juvenile is a pretty interesting question.
　　为什么这头矮暴龙没有吃掉幼龙是个挺有意思的问题。
　　Something happened after the fight, that prevented it from eating this baby Rex.
　　战斗后发生了什么事情阻止了它吃掉这头幼霸王龙。
　　Nanotyrannus would have had an advantage over a juvenile T-Rex.
　　矮暴龙对一头幼霸王龙会有优势。
　　But two juveniles 8 against a Nano would have radically 9 changed the dynamic of the fight.
　　不过两头幼龙对抗一头矮暴龙会极大地改变战斗的态势。
　　By studying the bone fragments from the scene, CAT scan and environmental evidence, and using modern animal behaviour as a guide,通过研究现场的骨头碎片CT扫描和环境证据，并且使用现代动物行为作为参考，experts were able to reconstruct a plausible 10 scenario 11, one that took place in South Dakota 65 million years ago.
　　专家们能够重建当时可能的情形，那六千五百万年前发生在南达科塔州的故事。
