0:01:16 > 0:01:19Hi, I'm Andy, and I work here in the dinosaur gallery of
0:01:19 > 0:01:20the National Museum.
0:01:20 > 0:01:23Hatty's working on a brand-new display today about some of the
0:01:23 > 0:01:26animals that lived in the time of the dinosaurs.
0:01:26 > 0:01:29And I'm off to get my first look. Come on.
0:01:34 > 0:01:35Hatty?
0:01:37 > 0:01:38Hatty?
0:01:38 > 0:01:40ROAR!
0:01:40 > 0:01:42- ROAR!- Oh, very funny.
0:01:42 > 0:01:46Sorry, I was putting in his teeth and heard you coming.
0:01:46 > 0:01:49- What do you think? - Amazing! What's his name?
0:01:49 > 0:01:50"I'm a postosuchus."
0:01:50 > 0:01:52- A posto-who?- A postosuchus.
0:01:52 > 0:01:57He wasn't a dinosaur, he was a cousin of the crocodiles we have today.
0:01:57 > 0:02:00Before the dinosaurs came along, he was the biggest meat eater
0:02:00 > 0:02:02on the planet.
0:02:02 > 0:02:05Not only that, he had big eyeholes which means he had good eyesight
0:02:05 > 0:02:08and long nostrils which means that he probably had
0:02:08 > 0:02:10a good sense of smell too.
0:02:10 > 0:02:13- And, some pretty big teeth. - And sharp too.- Can I touch one?
0:02:13 > 0:02:14Of course.
0:02:14 > 0:02:15Ow!
0:02:17 > 0:02:21They're not real though. It's quick drying plaster powder and water.
0:02:21 > 0:02:22- They look real.- So they should.
0:02:22 > 0:02:25I used the plaster powder to make copies
0:02:25 > 0:02:27of some real postosuchus teeth
0:02:27 > 0:02:29I found in a museum in the United States.
0:02:29 > 0:02:32Oh, I'd better get going, the museum opens soon.
0:02:32 > 0:02:35Could you pass me the last few teeth from the trolley?
0:02:35 > 0:02:37Yep.
0:02:42 > 0:02:43Oh, there aren't any.
0:02:43 > 0:02:45What?
0:02:46 > 0:02:48That's strange.
0:02:48 > 0:02:51I'm sure I made enough.
0:02:51 > 0:02:56- Maybe I got my counting wrong. - Do you definitely need them?
0:02:56 > 0:02:58I can't leave him with a big gap in his mouth.
0:02:58 > 0:03:02He looks like he's had a bad day at the dentist. Museum opens soon.
0:03:02 > 0:03:06- Don't worry, Hattie. I'll sort it out.- But you don't have time.
0:03:06 > 0:03:08BELL RINGS
0:03:15 > 0:03:19- I'll make time.- Thanks, Andy, I knew I could count on you.
0:03:19 > 0:03:21Always.
0:03:23 > 0:03:25Time to go on a dinosaur adventure!
0:03:36 > 0:03:39Right - waistcoat,
0:03:39 > 0:03:43Gizmo, hat, and last but not least, Hatty's backpack.
0:04:02 > 0:04:04To the time of postosuchus!
0:04:40 > 0:04:41I made it!
0:04:41 > 0:04:44I've travelled back in time 220 million years,
0:04:44 > 0:04:47to the time of postosuchus.
0:04:47 > 0:04:49OK, all I need to do is find the postosuchus
0:04:49 > 0:04:52and get plaster copies of some of its teeth.
0:04:52 > 0:04:54Where do I look first though?
0:04:54 > 0:04:56Drrr! Drrrr!
0:04:56 > 0:04:58That sounds promising.
0:05:21 > 0:05:24Coelophysis, a whole herd of them.
0:05:24 > 0:05:28It says here that coelophysis were one of the first dinosaurs.
0:05:28 > 0:05:31These guys are tiny compared to the ones that came later
0:05:31 > 0:05:35but still fearless and great at hunting in packs.
0:05:40 > 0:05:41Clay.
0:05:41 > 0:05:47I can use this clay to make a mould for the postosuchus' teeth.
0:05:49 > 0:05:52Here we go. That should do it. Brilliant.
0:05:52 > 0:05:55Now all I need is a postosuchus.
0:05:55 > 0:05:57Roar!
0:05:57 > 0:05:59Where have the coelophysis gone?
0:06:02 > 0:06:03A postosuchus!
0:06:04 > 0:06:06That's why they've gone.
0:06:08 > 0:06:10Roar!
0:06:12 > 0:06:14Woah, listen to that roar.
0:06:16 > 0:06:18Look at the size of those teeth.
0:06:19 > 0:06:22How can I get close enough to get that mould?
0:06:23 > 0:06:25I've got an idea.
0:06:28 > 0:06:29Here we go!
0:06:33 > 0:06:34It worked!
0:06:34 > 0:06:38Oh, well, sort of. Oh, hang on.
0:06:43 > 0:06:47There's another one there - this could mean trouble.
0:06:47 > 0:06:50It says here that they don't like other postosuchus
0:06:50 > 0:06:53coming on to their territory without being invited.
0:06:56 > 0:07:00I hope they don't fight, I can barely hold on.
0:07:10 > 0:07:12I think we've scared him away.
0:07:17 > 0:07:20This one is marking his territory with his wee,
0:07:20 > 0:07:21just like cats and dogs do.
0:07:21 > 0:07:26So, any postosuchus that comes by will smell it and know
0:07:26 > 0:07:27to steer clear.
0:07:29 > 0:07:31I don't blame them either, it stinks!
0:07:33 > 0:07:34We're off again.
0:07:37 > 0:07:39Oh, this is much better.
0:07:39 > 0:07:43Still got to get the imprint of its teeth though.
0:07:43 > 0:07:45I'm not sure I'm going to be able to do that
0:07:45 > 0:07:47without it biting me.
0:07:47 > 0:07:51Unless... I could wait for it to fall asleep.
0:07:51 > 0:07:55Hmm, I'm not sure that's going to happen any time soon though.
0:07:56 > 0:07:59What's happening? What's it seen?
0:07:59 > 0:08:01Hang on a minute.
0:08:02 > 0:08:06Placerias, digging up some roots.
0:08:06 > 0:08:08Postosuchus here must be hungry
0:08:09 > 0:08:11I hope they're going to be OK.
0:08:11 > 0:08:15There's a whole herd of them, they should be fine.
0:08:15 > 0:08:20And they look and sound pretty feisty too.
0:08:20 > 0:08:23Sorry, postosuchus, this isn't your lucky day.
0:08:29 > 0:08:32Well, I've been on this postosuchus for ages now.
0:08:32 > 0:08:36He still doesn't seem like he's going to fall asleep though.
0:08:38 > 0:08:41If anything, he seems to be getting...
0:08:41 > 0:08:42..livelier!
0:08:45 > 0:08:46Woah!
0:08:46 > 0:08:49There, there, calm down. It's all right.
0:09:04 > 0:09:06Right, he's stopped.
0:09:06 > 0:09:08Now is my chance.
0:09:13 > 0:09:14Just reach there...
0:09:16 > 0:09:18Woah!
0:09:41 > 0:09:43Oh, where's he gone now?
0:09:43 > 0:09:46I'm never going to get a copy of his teeth at this rate.
0:10:02 > 0:10:05At last! I think he's asleep.
0:10:05 > 0:10:07I think it's safe to go near.
0:10:09 > 0:10:11Now, to make the mould.
0:10:17 > 0:10:18Perfect.
0:10:18 > 0:10:20Now, to make the teeth themselves.
0:10:23 > 0:10:27Plaster powder,
0:10:27 > 0:10:30and the water.
0:10:40 > 0:10:42Look at that!
0:10:42 > 0:10:46And we have three postosuchus teeth.
0:10:49 > 0:10:50Perfect.
0:10:52 > 0:10:54I'll just put these safely in the bag.
0:10:54 > 0:10:56BELL RINGS
0:10:56 > 0:10:58We should have just enough time
0:10:58 > 0:11:00to get back to the museum before it opens.
0:11:05 > 0:11:08He's woken up, and he's got me by the trousers.
0:11:08 > 0:11:10What am I going to do?
0:11:10 > 0:11:11Oh, get off!
0:11:11 > 0:11:15Hatty's backpack is always full of useful things.
0:11:16 > 0:11:18Boomerang?
0:11:18 > 0:11:20How's that going to help me?
0:11:22 > 0:11:23Unless...
0:11:28 > 0:11:29It worked!
0:11:32 > 0:11:34Time to head...
0:11:37 > 0:11:39..back.
0:12:22 > 0:12:24BELL CHIMES
0:12:33 > 0:12:35Right, hurry along now.
0:12:42 > 0:12:45This is the skull of a postosuchus,
0:12:45 > 0:12:50a crocodile-like animal that lived 220 million years ago.
0:12:51 > 0:12:53As you can see,
0:12:53 > 0:12:58it had lots of very sharp teeth that were perfect for chewing meat.
0:12:58 > 0:13:00And trousers.
0:13:00 > 0:13:04In its day, it was the biggest hunter on Earth.
0:13:05 > 0:13:08Thanks, Andy, those teeth look fantastic.
0:13:08 > 0:13:12At last it really looks like it could take a bite out of something.
0:13:12 > 0:13:13Grr.
0:13:15 > 0:13:18Shh. See you next time.
0:13:32 > 0:13:34# One, two, three, four
