We have meat-eating dinosaur footprints, but all of them seem to be solitary.
我們也發現了食肉恐龍的腳印，但都是單獨的腳印
Even when we have a track-way of several footprints in a row,
就算找到一連串腳印的痕跡
we never seem to have any track-way with it that show a group of animals moving together.
我們也沒有發現能證明它們一起走路的證據
So whereas that is actually rather common for the plant-eating dinosaur footprints,
總之植食恐龍腳印的共同特征
it's essentially absent for the meat-eating dinosaurs footprints.
在食肉恐龍的腳印中根本不存在
There is another key piece of evidence which supports the view that plant-eating dinosaurs were group animals.
另外還有一個關鍵的證據能支持植食恐龍是群居動物的觀點
This desolate landscape contains a bone bed, a collection of dinosaur bones buried together.
這片荒涼的土地中有一個化石坑，埋藏著一大群恐龍的骨骼化石
The fossilized remains of hundreds of plant-eating dinosaurs,
足球場般大小的土坑內躺著數百具恐龍骨骼，
all of the same species, could die together, carpet an area the size of a football pitch.
它們都是同一種植食恐龍，一起死于非命
This bone bed is full of horned dinosaurs of different ages - little babies, large full-grown ones.
這個化石坑中都是大大小小的角龍，小恐龍，還有成年大恐龍
And it's clear that they were probably crossing a swollen river and got drowned trying to cross.
它們很可能正在橫渡一條泛濫的河流，結果全都淹死在里面了
