霸王龍是否比我們想象中的更善于交際？一直以來，科學(xué)家們都曾以為霸王龍是離群索居的食肉動物，喜歡獨自捕食和生活。然而，來自美國阿肯色大學(xué)的一組古生物學(xué)家可能發(fā)現(xiàn)了有關(guān)這種可怕動物的一個新理論。

The theory that tyrannosaurs were social animals was first suggested 20 years ago. That was when a dozen of the creatures were found at a site in Alberta, Canada. Another such mass death site was later found in Montana. This one in southern Utah again shows that tyrannosaurs died in the same place.

霸王龍是群居動物的理論最早是在20年前提出的。當(dāng)時，加拿大阿爾伯塔省某處發(fā)現(xiàn)了十幾只霸王龍的遺骸。后來，美國蒙大拿州又發(fā)現(xiàn)了另一個這樣的霸王龍集體死亡遺址。這次，在美國猶他州南部發(fā)現(xiàn)的遺址再次表明，霸王龍是在同一地點死亡的。

Analysing the bones and rocks, a team of palaeontologists from the University of Arkansas say it suggests the tyrannosaurs came together to prey on other animals, at least when times got tougher and resources were dwindling. 

來自美國阿肯色大學(xué)的一組古生物學(xué)家在分析了骨骼和化石后說，這表明這些霸王龍曾聚集在一起捕食其它動物，至少在生存艱難、資源日益減少的日子里是這樣的。

These conclusions add to mounting evidence that they may not so much have been lone predators, but hunted in packs like wolves, which makes them, as hard to imagine as that may seem, even more terrifying.

這些結(jié)論再次證實霸王龍可能并非離群索居的食肉動物，而是像狼一樣成群結(jié)隊地捕食，簡直想不到霸王龍還可以比我們原本想象得更可怕。
