与恐龙同行（2025）

This is a big bone.
这只恐龙的体长
This animal would have been you know,
可能达到了六 七米
may be around six seven metres long.
但这既不是三角龙
But this is no Triceratops,
也不是霸王龙
it's not a T Rex either.
叫声在森林中回荡
Echoing through towering trees.
这可能是拉腊米迪亚古陆
The calls of perhaps the strangest dinosaurs
最奇特的一种恐龙
who roam here.
埃德蒙顿龙
Edmontosaurs.
它们被誉为白垩纪的牛群
Herd animals known as the cows of the Cretaceous.
这些体重超过6吨♥的庞然大物
Weighing over six tonnes,
并不排斤克洛弗
these social creatures tolerate Clover.
克洛弗是草食性恐龙
As a fellow plant eater
不会对它们构成威胁
she's no threat to them.
而埃德蒙顿龙也能为克洛弗提供保护
The herd could give Clover the protection she needs.
克洛弗不仅得到了保护
And it's not just safety they offer.
它还得到了一个玩伴
A playmate.
在这些庞然大物中间
In amongst these giants.
克洛弗终于有了安全感
Clover can begin to feel safe.
但是丛林中危机四伏
But danger is never far away.
6600万年前
66 million years ago,
霸王龙统治着这片土地
T Rex ruled over these lands.
它们称霸了超过200万年
The apex predator for over two million years.
翻过来时要用手托住下面
As it rolls over just get your hands under it.
发掘团队想知道
The team wants to discover
这种凶猛的猎手是如何捕杀猎物的
how this fierce some hunter took down its prey.
石膏保护层内部是霸王龙的腿骨化石
Inside this protective plaster coat is the predators leg bone.
埃里克认为下方还藏着更多秘密
Eric thinks there might be more underneath.
一 二 三
One, two, three.
裸♥露♥在岩石外面的
Protruding from the rock.
一块骨头
That's a bone.
一块巨大的椎骨
One of the giants vertebrae.
保存得非常好
Beautiful preservation.
这是只巨大的霸王龙
It was a big, big animal.
借助这根椎骨
It allows Eric
埃里克可以准确推算霸王龙的体形
to estimate more accurately T Rex's full size.
体长约为10米 甚至可能更长
In the order of 30 feet, maybe more, 10 metres, something like that.
他们用浸满石膏的织物把化石包裹起来
They wrap their discoveries in a protective plaster jacket.
虽然这块化石大得惊人
It's just a tiny fraction of T Rex's skeleton
但它只是霸王龙骨架的一小部分
but it's enormous.
石膏外壳的重量约为150公斤
This jacket's probably about 150 kilograms,
也就是二 三百磅
200 300 pounds.
真是太大了
It's just so huge.
成年霸王龙的体重超过8吨♥
Alive, adult T Rex weighed over eight tonnes,
但庞大的体形也有劣势
but this enormous weight may actually have been a hindrance.
霸王龙不是《侏罗纪公园》里
Certainly not a 40 mile an hour
那种时速60公里的杀戮机器
Jeep chasing animal that Jurassic Park,
它们的生理结构无法承受这种速度
their physiology just wouldn't allow them to run that fast.
它们可能只会快走
Probably speed walker.
霸王龙可能并不会奔跑
T Rex probably couldn't run
因为这会让它们扭断腿
for fear of breaking its own legs.
它们的最高移♥动♥速度
With a top speed
可能是每小时二 三十公里
of just 15 or 20 miles an hour.
虽然并不慢
Not exactly slow,
但是快速奔跑完全能摆脱它们
but a fast human could out sprint one.
我觉得可以
I think he could,
只要突然转个向
I think I'm gonna take a sharp turn
我就能摆脱霸王龙
and it's gonna have a hard time following me.
你觉得只要比它跑得快就没问题
You think we only just gotta be faster than him.
也许有点过于自信了
May be I'm a little over confident.
所以成年霸王龙并不会快速奔跑追逐猎物
So adult T Rex weren't sprinting after their prey.
这位猎手依靠的是另一种捕食策略
This killer relied on another tactic.
突袭
The element of surprise.
当克洛弗和埃德蒙顿龙熟睡时
As Clover and the Edmontosaurs sleep soundly,
霸王龙从下风处慢慢逼近
T Rex approaches slowly from downwind.
对体形和公交车相当的动物来说
But it's not easy being stealthy
想做到悄无声息并不容易
when you're the size of a bus.
埃德蒙顿龙排成防御阵型
The Edmontosaurs form a defensive line.
它们抬起前腿
Rearing up on their hind legs
以便让自己看起来更具威力
to appear as big as possible.
然而想保持冷静并不容易
But holding your nerve isn't easy.
只要有一只退缩 恐龙群就会陷入恐慌
And it only takes one of the herd to panic.
克洛弗侥幸逃脱
A lucky escape for Clover,
它的新朋友沦为了猎物
not for her new friend.
随着成年埃德蒙顿龙离去
With the adult Edmontosaurs on the move,
克洛弗只能继续独自生活
Clover is alone once more.
在白垩纪晚期
Survival was a game of chance
生存是一场充满风险的游戏
in the late Cretaceous
像克洛弗这样的幼龙会遭遇许多挑战
and the odds were stacked against young dinosaurs like Clover.
团队发现的一块化石
The team has tracked down a remarkable fossil
为我们揭示了一个令人毛骨悚然的故事
with a chilling tale to tell.
这是一块非常奇特的化石
Got the weirdest baby bundle ever.
看似普通岩石的块状物
It may look like a nondescript lump of rock,
其形状和质地让专家确认这是一块粪化石
but it's shape and texture tell the experts, this is a co prolite
也就是粪便形成的化石
fossilized faeces.
埃里克与化石修复师奥伯里·诺尔斯
Eric works with fossil restorer Aubrey Knowles.
长67.5厘米 也就是26.5英寸
67 and a half centimetres or 26. 5 inches.
对这块史前"粪便"展开了调查
To examine this prehistoric poo.
真是一大块粪便 真是一大块粪便
That's a massive turd. That's a really big turd.
科学家很难确定粪化石属于哪种恐龙
Most coprolites can't be attributed to any specific species,
不过这块恐龙粪化石中残留的骨碎片
but bone fragments within the dino dung
表明这是一只食肉恐龙
reveal this was the waste product of a meat eater.
粪化石的大小说明
And then there's the matter of size.
直径是15.7厘米
So we're at 15. 7 centimetres across
也就是6.2英寸
or 6. 2 inches.
它的泄殖腔可真大
That's a wide cloaca.
确实非常大
That is a very wide bum hole.
唯一能排出
The only large bodied
这种巨大粪便的大型食肉恐龙
carnivorous dinosaur that could have possibly dropped this
就是霸王龙
would be a T Rex,
所以这很有趣
so very very cool.
这是一块不同寻常的化石
It's an astonishing fossil.
史上最臭名昭著的猎食者的排泄物
The excrement of the most notorious predator in history.
有趣的是粪便里残留着许多骨碎片
It's interesting how many bones there are preserved in the dropping.
通过检查粪化石
By examining coprolites,
我们甚至能辨认受害的猎物
it's even possible to identify the killer's victims.
霸王龙的粪化石中
T Rex faeces
往往残留着一些细小光滑的骨头
have been found to contain bones that are small and smooth.
这说明它偏爱幼年猎物
That speaks to a more juvenile or young prey.
也就是幼龙的骨头
The bones of babies.
幼龙很容易受到攻击
Baby dinosaurs would be very vulnerable.
被一口吞下
Bite sized.
为了保存体力
Energy is precious,
它们会捕捉容易得手的猎物
go after easy prey.
为了维持庞大的体形
Needing a quarter of a tonne of meat a week
霸王龙每周需要摄入约0.25吨♥的肉
to sustain their enormous bulk,
像克洛弗这样的幼龙
baby dinosaurs like Clover
是霸王龙经常捕食的猎物
were a common meal for T Rex.
而且霸王龙对各类食物来者不拒
Nothing is off the menu.
克洛弗缺少警惕性
Naive,
毫无防御能力
defenceless
还能被一口吞下
and small enough to swallow whole,
是理想的猎物
Clover would make an excellent snack.
对无处可藏的克洛弗来说
With nowhere to hide,
一个老相识或许能为它带来一丝转机
it's a good time to bump into an old acquaintance.
很少有动物能挑战霸王龙
Few creatures can challenge T Rex
成年三角龙可能是唯一一种
but a full grown Triceratops might be the only animal
敢于和霸王龙正面抗衡的恐龙
that doesn't need to turn and run.
谁是这场鏖战的终极获胜者
Who wins in a fight?
是三角龙还是霸王龙
Triceratops or T Rex?
为了赢得这场生存竞争
