But Currie felt he had an answer to this. These tyrannosaurs were rare dinosaurs.
不過Currie覺得他能解釋這個問題。這些暴龍是比較稀少的恐龍
They would have made up only five per cent of the animal life in this area.
它們只占到了這片地區動物數量的5％
The chances that 12 unrelated tyrannosaurs died separately and were washed together to this spot were minute.
12只暴龍分別死去，然后又被洪水沖到一起的幾率微乎其微
To find 12 tyrannosaurs by chance, at this level, in this bone bed.
12只暴龍碰巧一起被埋在這個地層、這個化石場中
The chances of that happening are about one in 64 million.
這種事件的發生幾率只有1/64000000
It really isn't very likely that it's going to happen by chance.
所以這種事幾乎不可能碰巧發生
But there could be an even more dramatic reason why the bones of Currie's tyrannosaurs were all in one place.
不過還有一種更戲劇性的解釋能說明Currie發現的暴龍骨骼為何會被埋在同一個地方
They could all have been caught in a predator trap. This is a predator trap.
它們可能一起落入了掠食動物陷阱。這就是掠食動物陷阱
In this strange swamp-like place, molten tar has bubbled up from deep within the Earth for tens of thousands of years.
在這片沼澤般的詭異地帶，熔化的焦油數萬年來不斷從地底深處噴涌而出
The sticky tar is lethal to any animal that wanders into it.
粘稠的焦油對于任何失足的動物來說都是致命的
Within seconds, the creature will become stuck, and then its fate is sealed.
幾秒鐘內，動物可能就被吞沒，它的命運也隨之封存
Predator traps have been found all around the world. This one is in downtown Los Angeles.
掠食動物陷阱遍布全世界各地。這個位于洛杉磯市區內
