纪录片《巨龙的奥秘》 第12期 群居的证明

We have meat-eating dinosaur¹ footprints, but all of them seem to be solitary².

我们也发现了食肉恐龙的脚印，但都是单独的脚印

Even when we have a track-way of several footprints in a row,

就算找到一连串脚印的痕迹

we never seem to have any track-way with it that show a group of animals moving together.

我们也没有发现能证明它们一起走路的证据

So whereas that is actually rather common for the plant-eating dinosaur footprints,

总之植食恐龙脚印的共同特征

it's essentially³ absent for the meat-eating dinosaurs⁴ footprints.

在食肉恐龙的脚印中根本不存在

There is another key piece of evidence which supports the view that plant-eating dinosaurs were group animals.

另外还有一个关键的证据能支持植食恐龙是群居动物的观点

This desolate⁵ landscape contains a bone bed, a collection of dinosaur bones buried together.

这片荒凉的土地中有一个化石坑，埋藏着一大群恐龙的骨骼化石

The fossilized remains⁶ of hundreds of plant-eating dinosaurs,

足球场般大小的土坑内躺着数百具恐龙骨骼，

all of the same species, could die together, carpet an area the size of a football pitch.

它们都是同一种植食恐龙，一起死于非命

This bone bed is full of horned dinosaurs of different ages - little babies, large full-grown ones.

这个化石坑中都是大大小小的角龙，小恐龙，还有成年大恐龙

And it's clear that they were probably crossing a swollen⁷ river and got drowned trying to cross.

它们很可能正在横渡一条泛滥的河流，结果全都淹死在里面了
