寻找化石

Mary Anning: Fossil Hunter

谁喜欢恐龙呢?
Who loves dinosaurs?
我知道你喜欢 斯奎克斯 我也喜欢
I know you do, Squeaks, and I do, too!
恐龙是曾存于地球上让人敬畏的远古爬行动物之一
Dinosaurs were just one kind of awesome reptile that lived on Earth a long time ago.
还有一种叫做翼龙的飞行类爬行动物和各种大型海洋生物
There were also reptiles that flew, called pterosaurs, and all kinds of giant creatures
比如蛇颈龙、鱼龙等
of the sea, like plesiosaurs and ichthyosaurs!
如果不是玛丽·艾林的话 我们现在也不会这么了解这些
And we wouldn’t know nearly as much as we do about these amazing animals today, if it
神奇的动物
weren’t for a person by the name of Mary Anning.
距今250多年前 玛丽·艾林出生于英国
Mary Anning was born in England over 250 years ago.
她从不去上学 但是她会学习如何写作和阅读
She never went to school, but she learned how to write and read.
她把很多时间都花在了读书上 比如读科学堡垒最喜欢的话题
And she spent a lot of her life reading books — books about our favorite topic here at
科学
the Fort — science!
她最喜欢的是一些关于岩石的科学书籍
Some of her favorite science books were about rocks.
其它则是关于动物的 一些是她曾在自家后院看到的动物
Others were about animals — ones that she saw in her own backyard, and ones that lived
一些是很久以前的动物
a long time ago.
当玛丽还是一个年轻女孩时 她家临海而居
When Mary was a young girl, her family lived near the ocean.
所以当她阅读空闲之余 她就会沿着海边的悬崖散步
So, when she wasn’t busy reading, she would take walks along the cliffs near the sea and
并收集贝壳卖给游客
collect shells to sell to visitors.
而且她总是在寻找化石
And she also was always on the hunt … for fossils!
化石是存活于在很久以前的植物和动物的部分遗体
Fossils are the left-over parts of plants and animals that lived a long time ago.
当我说很久以前的时候……我的意思是很久很久很久以前
And when I say a long time ago…I mean a long time ago!
几百万年前的地球和我们如今所了解的非常不同
Millions of years ago, the Earth looked pretty different from how we know it today.
如果你看那些科学家们眼中地球的照片的话
If you look at a picture of what scientists think the Earth looked like then, you can
你可以看见以前的世界大部分都被海水覆盖着
see that a lot of the world was covered with water.
几百万年前 海洋里聚集着很多你如今看不到了的各种各样的
And millions of years ago, the ocean was full of lots of different kinds of plants and animals
植物和动物
than you see today.
这些生物死了之后 有一部分就会沉在海底
When these things died, parts of them fell to the bottom of the ocean and were buried
被海底下的沙砾和岩石所掩埋
under sand and rock.
很久以后 这些沉淀物就变成了化石
Over a long time, these parts left behind fossils.
留存到了今天
Fast forward to today!
以前活着的大多数动物和植物现在都灭绝了 这意味着
Most of the animals and plants that were alive then are now extinct, which means there aren’t
它们再也不存在了
any of them alive anymore.
地球也从那时开始改变
And the Earth has changed since then, too!
作为地球的一部分——海底世界也不复存在……
Some of the parts of the world that used to be under the ocean aren’t anymore…
包括玛丽居住的英国
…including where Mary lived, in England!
当她沿着海滩散步的时候 她能发现许多化石
So when she took her walks along the beach, she was able to find lots of fossils left
这些原本是几百万年前生活在海里的生物
behind by things that lived in the ocean millions of years ago.
这就是为什么当玛丽仅年满12岁
And that’s why, when Mary Anning was only twelve years old, she discovered the fossil
就能发现灭绝的海底巨型动物
of a big, extinct animal that lived in the ocean.
她和她11岁的弟弟发现了一只已经灭绝了的爬行动物鱼龙的
She and her eleven year old brother found the entire skeleton of an extinct reptile
整个骸骨
called an ichthyosaur.
你觉得鱼龙像其它动物吗
Do you think an ichthyosaur looks like another animal?
我也觉得像 斯奎克斯
I agree, Squeaks!
就像鱼和海豚 这种动物有鳍和脚蹼帮助它在海里游泳
Like fish and dolphins, this animal had fins and flippers to help it swim in the ocean.
但不要混淆了 鱼龙不是鱼 而且它也不是哺乳动物
Don’t be fooled, though — the ichthyosaur wasn’t a fish, and it wasn’t a mammal,
它不像海豚
like dolphins are.
鱼龙是爬行动物 就像蛇和蜥蜴一样
Ichthyosaurs were reptiles, like snakes and lizards.
现在鱼龙已经不是玛丽·艾林唯一的杰出发现了
Now, the ichthyosaur wasn’t Mary Anning’s only excellent discovery!
因为她还是首个发现另一种已灭绝的爬行动物骸骨的人
She was also the first to discover a whole skeleton of another extinct reptile—the
那就是蛇颈龙
plesiosaur.
蛇颈龙和鱼龙一样生活在海里
Like the ichthyosaur, the plesiosaur lived in the ocean.

And check it out!
当人们第一次看见艾林发现的骸骨时 一些人根本不相信
When people first saw the skeleton that Anning had found, some people didn’t believe it
这是真的
was real!
因为艾林在学校里不学科学 那时候许多科学家都认为
Because Anning didn’t study science in school, many scientists at the time didn’t think
她的成果不应该被重视
that her work should be taken seriously.
但那也没能阻止她
But that didn’t stop her.
她继续寻找 继续学习 继续为她找到的化石作画
She kept looking…and learning…and making drawings of the fossils that she found.
这些都成功地引起了其他人的兴趣并且为她的发现而感到激动
All of these things helped get other people interested and excited about her discoveries.
玛丽·艾林还破解了关于古代生物的一个谜
And there’s one more mystery about ancient animals that Mary Anning solved.
当她在研究鱼龙和蛇颈龙的化石时 她在动物的骨头之间发现了
While she was studying fossils of ichthyosaurs and plesiosaurs, she found some small, strange
一些小小的 奇怪的石头
stones among the animals’ bones.
其它的科学家也发现了并且他们也不知道那是什么
Other scientists had found them, too, and they didn’t know what they were, either.
但是艾林非常好奇 决定将骨头敲开 看看里面有什么
But Anning was curious about them, and decided to break them open to see what was inside.
最后她发现里面是一些更小的其它动物的骨头 就像鱼
And what she found inside was — even smaller bones of other kinds of animals, like fish
还有其它海洋生物
and other sea creatures.
她意识到这些小小的骨头是一种全新的化石……石化的大便
She realized that the small stones were a whole new kind of fossil…fossilized poop!
这些奇怪的小石头包含许多古老海洋爬行动物
Those weird little rocks contained the bits of animals that those old ocean reptiles had
所吃的东西
eaten!
玛丽·艾林的研究让我们知道了几百万年前生命的模样
Mary Anning’s work taught us a lot about what life was like millions of years ago — even
虽然那些生命形式和如今我们熟知的生命形式相比有些奇怪
though that life often looked strange compared to the living things we know today.
她穷极一生研究她身旁的世界她尽可能地阅读、询问、学习
She spent her life looking at the world around her…reading…asking questions…and learning
有关科学的学问
everything she could about science.
嘿 这听起来就像她正好适合科学堡垒这个舞台
Hey, it sounds like she’d fit right in here at the Fort!
