Every environment has an apex predator, that is the ultimate predator at the top of the food chain.

每種環(huán)境里都有頂級掠食者，就是位于食物鏈頂端的終極掠食者。

On North America, Tyrannosaurus-Rex was that apex predator.

在北美洲，霸王龍是頂級掠食者。

不過在馬達加斯加島，則是瑪君龍。

Majungasaurus was the top predator in its community.

瑪君龍是它的環(huán)境里的頂級掠食者。

In general, it would've spent its day stalking around for prey, killing something,and when it killed it, ate it, and rested for a while.

一般情況下，它會整天搜尋獵物然后殺死并吃掉，然后休息一會兒。

As more bones emerged from the site, scientists began to get a clearer picture of the size and shape of this creature.

隨著出土的骨頭越來越多，對這種生物的大小和形態(tài)科學家們有了更清晰的認識。

He was a two-legged predator, standing three meters tall, nine meters long and weighing one ton, the same as a baby elephant.

它是一種兩足行走的掠食者，站起來有三米高長達九米、重量有一噸相當于一頭幼年大象。

Along with its size and a reinforced head butting skull, Majungasaurus had a even more dangerous mouthful of serrated teeth.

除了有壯碩的身體和結實的頭顱，瑪君龍滿口的鋸齒形牙齒更加危險。

Closer inspection of the jaws would reveal that, like a shark, Majungasaurus had rows of teeth that continuously replaced themselves.

The teeth of Majungasaurus were pretty incredible. They were replaced throughout its entire life.

瑪君龍的牙齒挺不可思議。它們一直都在不斷地更新。

When a tooth got dull, it would fall out and be replaced by a brand new tooth.

當一顆牙變鈍了就會掉下被換成一顆新牙。

They were also serrated on both of front and back edges making them perfect for slicing meat.

而且前后邊緣都有鋸齒，非常適合切肉。

Majungasaurus still had a further weapon that was capable of delivering a lethal blow, its massive tail.

瑪君龍還有一樣武器也能夠給出致命一擊，就是巨大的尾巴。

With reinforced bones and powerful muscles, the dinosaur could wield its tail like a oversized baton.

尾巴上有加強的骨頭和有力的肌肉，揮動起來就像超大的警棍。

Although Majungasaurus was a force to reckon with, it was not without shortcomings.

盡管瑪君龍的威力驚人，它也有自己的缺點。

Even the king of the jungle has weaknesses. A first was its unusually small arms.

這個叢林之王也有薄弱環(huán)節(jié)。首先就是它異常小的前肢。
