Hi, I'm Andy, and I work here in the dinosaur gallery of

the National Museum.

Hatty's working on a brand-new display today about some of the

animals that lived in the time of the dinosaurs.

And I'm off to get my first look. Come on.

Hatty?

Hatty?

ROAR!

-ROAR!

-Oh, very funny.

Sorry, I was putting in his teeth and heard you coming.

-What do you think?

-Amazing! What's his name?

"I'm a postosuchus."

-A posto-who?

-A postosuchus.

He wasn't a dinosaur, he was a cousin of the crocodiles we have today.

Before the dinosaurs came along, he was the biggest meat eater

on the planet.

Not only that, he had big eyeholes which means he had good eyesight

and long nostrils which means that he probably had

a good sense of smell too.

-And, some pretty big teeth.

-And sharp too.

-Can I touch one?

Of course.

Ow!

They're not real though. It's quick drying plaster powder and water.

-They look real.

-So they should.

I used the plaster powder to make copies

of some real postosuchus teeth

I found in a museum in the United States.

Oh, I'd better get going, the museum opens soon.

Could you pass me the last few teeth from the trolley?

Yep.

Oh, there aren't any.

What?

That's strange.

I'm sure I made enough.

-Maybe I got my counting wrong.

-Do you definitely need them?

I can't leave him with a big gap in his mouth.

He looks like he's had a bad day at the dentist. Museum opens soon.

-Don't worry, Hattie. I'll sort it out.

-But you don't have time.

BELL RINGS

-I'll make time.

-Thanks, Andy, I knew I could count on you.

Always.

Time to go on a dinosaur adventure!

Right - waistcoat,

Gizmo, hat, and last but not least, Hatty's backpack.

To the time of postosuchus!

I made it!

I've travelled back in time 220 million years,

to the time of postosuchus.

OK, all I need to do is find the postosuchus

and get plaster copies of some of its teeth.

Where do I look first though?

Drrr! Drrrr!

That sounds promising.

Coelophysis, a whole herd of them.

It says here that coelophysis were one of the first dinosaurs.

These guys are tiny compared to the ones that came later

but still fearless and great at hunting in packs.

Clay.

I can use this clay to make a mould for the postosuchus' teeth.

Here we go. That should do it. Brilliant.

Now all I need is a postosuchus.

Roar!

Where have the coelophysis gone?

A postosuchus!

That's why they've gone.

Roar!

Woah, listen to that roar.

Look at the size of those teeth.

How can I get close enough to get that mould?

I've got an idea.

Here we go!

It worked!

Oh, well, sort of. Oh, hang on.

There's another one there - this could mean trouble.

It says here that they don't like other postosuchus

coming on to their territory without being invited.

I hope they don't fight, I can barely hold on.

I think we've scared him away.

This one is marking his territory with his wee,

just like cats and dogs do.

So, any postosuchus that comes by will smell it and know

to steer clear.

I don't blame them either, it stinks!

We're off again.

Oh, this is much better.

Still got to get the imprint of its teeth though.

I'm not sure I'm going to be able to do that

without it biting me.

Unless... I could wait for it to fall asleep.

Hmm, I'm not sure that's going to happen any time soon though.

What's happening? What's it seen?

Hang on a minute.

Placerias, digging up some roots.

Postosuchus here must be hungry

I hope they're going to be OK.

There's a whole herd of them, they should be fine.

And they look and sound pretty feisty too.

Sorry, postosuchus, this isn't your lucky day.

Well, I've been on this postosuchus for ages now.

He still doesn't seem like he's going to fall asleep though.

If anything, he seems to be getting...

..livelier!

Woah!

There, there, calm down. It's all right.

Right, he's stopped.

Now is my chance.

Just reach there...

Woah!

Oh, where's he gone now?

I'm never going to get a copy of his teeth at this rate.

At last! I think he's asleep.

I think it's safe to go near.

Now, to make the mould.

Perfect.

Now, to make the teeth themselves.

Plaster powder,

and the water.

Look at that!

And we have three postosuchus teeth.

Perfect.

I'll just put these safely in the bag.

BELL RINGS

We should have just enough time

to get back to the museum before it opens.

He's woken up, and he's got me by the trousers.

What am I going to do?

Oh, get off!

Hatty's backpack is always full of useful things.

Boomerang?

How's that going to help me?

Unless...

It worked!

Time to head...

..back.

BELL CHIMES

Right, hurry along now.

This is the skull of a postosuchus,

a crocodile-like animal that lived 220 million years ago.

As you can see,

it had lots of very sharp teeth that were perfect for chewing meat.

And trousers.

In its day, it was the biggest hunter on Earth.

Thanks, Andy, those teeth look fantastic.

At last it really looks like it could take a bite out of something.

Grr.

Shh. See you next time.
