It’s unlike any other creature that has walked the planet.
它和这个星球上其他的生物都不相同。
T-Rex is different. Something about Tyrannosaurs and Tyrannosaurus Rex itself is different than other predatory dinosaurs.
“雷克斯霸王龙独具一格。霸王龙以及雷克斯霸王龙和其他的掠食性恐龙是不同的。”
But for such a celebrated killer able to take on the toughest creatures of the Cretaceous, some things just don’t add up. It’s slow. With a top speed not much more than 25 kilometers per hour, a T-Rex couldn’t even outrun a fit human. It’s also unwieldy, requiring a full two seconds to make a 45-degree turn.
但是，对于这样一种能够击败白垩纪最难对付生物的著名杀手来说，有些东西也不如人意。那就是它的速度。雷克斯霸王龙的最高速度超不过每小时25公里，甚至没有一个健康的人类速度快。它同样十分笨拙，转一个45度的圈就需要整整两秒钟。
If a T-Rex were to fall over while chasing a prey item, it might seriously wound itself. And its hands, with only two fingers are completely useless for gripping prey.
如果雷克斯霸王龙在追击猎物时摔倒，那它将可能受到严重的伤害。而雷克斯霸王龙的前肢仅仅两根手指，这对于抓住猎物来说完全没有作用。
After its giant size and its huge teeth, the thing we most notice about T-Rex are its dinky, little arms, these tiny, little arms that can’t even reach its mouth.
“研究过雷克斯霸王龙巨大的体型和牙齿后，我们接下来最容易注意到的就是雷克斯霸王龙小小的前肢，这些极小的前肢甚至不能触碰到它们自己的嘴部。”
The giant T-Rex is a baffling creature. There has to be more to this killer. How did this giant mouth on legs become the dreaded butcher of the Cretaceous? Was its raw power, its shark-like jaws, or something else entirely?
雷克斯霸王龙体型巨大并充满谜团。它身上一定还有更多的秘密。它长在腿部的大嘴又怎样成为了白垩纪最恐怖的“屠夫”呢？是因为它的强壮有力？它鲨鱼般的大口？还是完全因为其他的原因？
Fossils of Tyrannosaurus Rex have been unearthed in the U.S., Canada, and even Asia. For scientists, these discoveries point to one conclusion—this carnivore has little to fear, even from the most well-armed herbivore of the Cretaceous, Triceratops. But to bring down an animal this tough takes more than just brawn, muscle, and teeth. It requires planning and strategy.
雷克斯霸王龙的化石曾在美国，加拿大，甚至亚洲被发掘出。对于科学家们来说，这些发现都引向一个结论——这种食肉恐龙基本上无所畏惧，对于白垩纪防御力最强的食草恐龙三角龙也同样如此。但是，想要击倒像三角龙防御力这样强的动物，仅仅依靠发达的肌肉，牙齿还远远不够。同样需要的是计划以及战略。
The T-Rex is highly intelligent. Its cerebrum is one of the largest of the prehistoric world. It has the ability to process sophisticated sensory information.
雷克斯霸王龙智商极高。它的大脑是史前世界最大的动物大脑之一。它能够处理复杂的传感信息。
