Because it kind of looks more like a tooth.

A paleontologist is a scientist who studies fossils and Ben has brought in his collection for us to see.

古生物學家是研究化石的科學家，Ben 帶來了他的收藏品給我們看。

Fossils are the remains or traces plants and animals that lived along long time ago.

化石是很久以前動植物的遺骸或痕跡。

This is a tooth fossil from the mouth of a prehistoric shark, a Megalodon.

這是史前鯊魚巨齒鯊的牙齒化石。

The Megalodon was a very big shark that swam in the ocean many millions of years ago.

巨齒鯊是許多百萬年前生活在海洋裡的一種非常大的鯊魚。

When its teeth fell out, they sunk to the bottom of the sea floor and got buried.

牠們的牙齒掉落後，就沉到海底，被埋了起來。

They stayed hidden in the ground for a very long time until we found them as a fossil.

牠們在地底下藏了很久，直到我們發現牠們成為化石。

Ben，你是怎麼找到這些化石的？

I used lots of special equipment, like this mask to see under the water and this snorkel to breathe.

我用了好多特別的裝備，像是這個面鏡，讓我在水下看得清楚，還有這個呼吸管可以呼吸。

I also had a special camera attached to my chest when I found this fossil.

當我找到這顆化石的時候，我的胸前還裝著一臺特別的相機。

There I was at the top of the sea floor when I spotted something from the corner of my eyes.

那時候我正待在海底的上方，突然眼角瞥見了什麼東西。

I dove down to inspect it and there in front of me was a tooth from the biggest shark that ever lived.

我潛下去檢查，結果在我面前的，竟然是史上最大鯊魚的牙齒。

It's amazing to think that these giant sharks and dinosaurs once lived right here in Australia.

想到這些巨大的鯊魚和恐龍曾經就生活在澳洲，真是太讓人驚嘆了。

It took millions of years for these fossils to form and then for us to discover them.

這些化石要經過數百萬年的時間才能形成，然後我們才能發現它們。

I wonder if we can make fossils in less time because we don't have millions of years to wait.

我想知道我們能不能在比較短的時間內就做出化石，因為我們沒有數百萬年的時間可以等。

Yes, I'm going to Big Ted's party later and then I have to do some washing.

對啊，我等一下要去參加 Big Ted 的派對，然後我還得去洗衣服。

Well, then we better try and make some fast fossils.

嗯，那我們最好試著做一些快速的化石。

For this experiment, you'll need aluminium trays, soft clay, plaster of Paris, water, and

這個實驗，你需要鋁盤、軟黏土、熟石膏、水，還有

I'm thinking if we press these toy prehistoric creatures into the clay, they'll leave a shape in the clay.

我在想，如果我們把這些玩具史前生物壓進黏土裡，牠們就會在黏土上留下一個形狀。

Ah, and then we can use that shape to make a fossil.

然後我們就可以利用那個形狀來做化石了。

We have these trays with soft clay inside.

我們有這些裡面有軟黏土的盤子。

So first we're going to press down the clay.

所以我們第一步要壓一壓黏土。

One of the best things about being a scientist is being able to use your hands to discover all sorts of wonderful things.

身為科學家最棒的一件事，就是可以用雙手去發現各種很棒的東西。

現在來把我們的玩具壓進黏土裡。

I'm using this Attenborosaurus because I think it'll make a great shape as a fossil.

我用的是這隻阿滕波羅龍，因為我覺得牠做成化石的形狀會很棒。

An Attenborosaurus has four flippers to help it swim.

阿滕波羅龍有四個鰭狀肢可以幫助牠游泳。

And I think it looks like a cross between a lizard and a turtle.

而且我覺得牠看起來有點像蜥蜴和烏龜的混合體。

But rather than press its body into the clay, I'm going to make some dino fossil footprints.

不過與其把牠的身體壓進黏土裡，我想要做一些恐龍化石的腳印。

Leah, did you know that they had teeth the size of bananas?

Leah，你知道牠們的牙齒有香蕉那麼大嗎？

Well, let's press our toys into the clay.

好，那我們來把玩具壓進黏土裡。

They look like they've made a nice shape in the clay.

牠們在黏土裡做出漂亮的形狀了。

Now we need to carefully remove them so we don't ruin the shape in the clay.

現在我們要小心地把玩具拿出來，這樣才不會破壞黏土裡的形狀。

If the clay got squished then the shape would be ruined.

如果黏土被壓扁了，形狀就會被破壞。

So we're going to pour this plaster of Paris mix on top of the clay and wait for it to dry.

所以我們要把調好的熟石膏倒在黏土上面，然後等它乾。

You'll need a grown up to help you make the plaster of Paris mix.

你需要一個大人來幫你調熟石膏。

This is part of the process called casting.

That's where a liquid is poured into a mold and left to harden.

也就是把液體倒進模具裡，讓它變硬。

This creates a solid object in the shape of the mould.

這樣就會做出一個跟模具一樣形狀的實體。

So when the plaster is dry, we'll be left with the shape of our fossils.

所以等石膏乾了之後，我們就會得到恐龍化石的形狀了。

It's time for science and scientifically.

Now we just have to wait for the plaster to dry.
