0:01:16 > 0:01:19Hi, I'm Andy and I work in the dinosaur gallery,
0:01:19 > 0:01:22here, in the National Museum.
0:01:22 > 0:01:26Now, there's lots going on today because Hatty, our dinosaur expert,
0:01:26 > 0:01:30is opening a brand-new exhibit all about big dinosaurs.
0:01:30 > 0:01:31Can't wait to see it.
0:01:35 > 0:01:37Hey, look at the size of that skull.
0:01:40 > 0:01:43Hatty?
0:01:45 > 0:01:47Hatty! Hatty!
0:01:47 > 0:01:50Watch out, here I come!
0:01:51 > 0:01:53Hatty, what are you doing up there?
0:01:53 > 0:01:58Well, I've spent weeks making this fake fern to feed the dinosaur.
0:01:58 > 0:02:01That should put some flesh on his bones.
0:02:01 > 0:02:05WINCH SQUEAKS
0:02:05 > 0:02:08There. What do you think?
0:02:08 > 0:02:09It looks amazing, Hatty.
0:02:09 > 0:02:13I still can't believe the size of that skull.
0:02:13 > 0:02:15That's because it's a diplodocus,
0:02:15 > 0:02:19once thought to be the largest dinosaur in the world.
0:02:19 > 0:02:21Must have eaten everything in its way.
0:02:21 > 0:02:26Actually, diplodocus only ate plants, like that big fern up there.
0:02:26 > 0:02:28I'd love to see that.
0:02:28 > 0:02:31Well, you'd have to go back 152 million years.
0:02:31 > 0:02:35I'm not sure you have enough time before the museum opens.
0:02:35 > 0:02:39reminds me, I'd better get going. still got lots to do.
0:02:39 > 0:02:42- Don't worry, Hatty, I'll sort this out.- Thanks, Andy.
0:02:47 > 0:02:49HE WHISTLES
0:03:11 > 0:03:15No! Hatty's fern. What am I going to do?
0:03:16 > 0:03:20I can just stick them back on. Yes, I'll stick them back on.
0:03:20 > 0:03:23CLOCK CHIMES
0:03:27 > 0:03:32Or even better, I can get myself a new one.
0:03:32 > 0:03:34Time to go on a dinosaur adventure.
0:03:34 > 0:03:38ADVENTURE MUSIC
0:03:51 > 0:03:54Right, waistcoat...
0:03:55 > 0:03:58..check. Gizmo...
0:03:59 > 0:04:01..check. Hat...
0:04:03 > 0:04:06..check. And last, but not least, Hatty's backpack.
0:04:25 > 0:04:28To the time of diplodocus!
0:04:37 > 0:04:38Yeah!
0:04:55 > 0:04:57What...
0:04:57 > 0:05:00DINOSAUR SQUAWKS
0:05:03 > 0:05:08I've travelled 152 million years back in time...
0:05:08 > 0:05:10to the time of diplodocus.
0:05:13 > 0:05:18Look! There are ferns everywhere. This is going to be easy.
0:05:23 > 0:05:26Hang on a minute. It's not going to be that easy.
0:05:26 > 0:05:29These aren't the ferns I'm looking for.
0:05:29 > 0:05:32To find the giant ferns, I need to get outside the forest.
0:05:32 > 0:05:35Which way? This way.
0:05:55 > 0:05:58DISTANT CLUCKING
0:06:00 > 0:06:04I haven't found my way out of the forest yet.
0:06:05 > 0:06:07I got a bit distracted.
0:06:09 > 0:06:12Baby diplodocus - a whole group of them,
0:06:12 > 0:06:15but why are they here and not the adult ones?
0:06:17 > 0:06:18Oh...
0:06:18 > 0:06:22They live in the forest they can hide in plants,
0:06:22 > 0:06:26in case hungry dinosaurs come and try and find them.
0:06:26 > 0:06:28Let's get a closer look.
0:06:34 > 0:06:39As you can see, they don't just hide in the plants, they eat them, too.
0:06:39 > 0:06:43They are stripping the leaves off the ferns and gobbling them down...
0:06:43 > 0:06:47without even chewing. Terrible table manners!
0:06:47 > 0:06:51But they need to eat lots and get as big as the adults.
0:06:55 > 0:06:58That might be one of the adults now. Come on!
0:06:58 > 0:07:01DINOSAURS BURP
0:07:07 > 0:07:10It's a pterosaur.
0:07:10 > 0:07:13This one's only tiny but it says here that some
0:07:13 > 0:07:18pterosaurs were the largest flying animals that ever lived.
0:07:18 > 0:07:20Where's he off to?
0:07:22 > 0:07:26But no pterosaur was ever the size of...
0:07:26 > 0:07:28this dinosaur.
0:07:28 > 0:07:30DINOSAUR GROWLS
0:07:32 > 0:07:37Ho, ho! Look at the size of this diplodocus. It's huge!
0:07:37 > 0:07:41It's only a teenager which means it'll get even bigger.
0:07:44 > 0:07:48Look! There are some more over there.
0:07:48 > 0:07:51And they're eating ferns, too.
0:07:51 > 0:07:54Are those are the ones I need? No.
0:07:54 > 0:07:58The ones I need are the giant ferns that the adults eat.
0:07:58 > 0:08:01I need to get out of this forest. Come on.
0:08:06 > 0:08:08Well, I'm out of the forest now
0:08:08 > 0:08:11but I still can't see any adults anywhere.
0:08:11 > 0:08:14What's that sound? Why is the ground shaking?
0:08:26 > 0:08:28HE LAUGHS
0:08:28 > 0:08:31Oh, yes! Look at the size of their necks...
0:08:31 > 0:08:34and their tails! They're massive!
0:08:34 > 0:08:38This is exactly what I've been looking for -
0:08:38 > 0:08:40a whole herd of adult diplodocus.
0:08:40 > 0:08:43IT ROARS
0:08:47 > 0:08:49Right, I'm going to follow them.
0:08:49 > 0:08:52Hopefully, they are off to eat giant ferns.
0:08:52 > 0:08:54Then I can grab some, too.
0:09:08 > 0:09:09IT GROWLS
0:09:16 > 0:09:19Did you see that?
0:09:19 > 0:09:23An adult diplodocus has pushed down the tree to get to the
0:09:23 > 0:09:25giant ferns on the other side.
0:09:27 > 0:09:29Come on.
0:09:31 > 0:09:34Oh, these are perfect!
0:09:34 > 0:09:38Just what I need to replace Hatty's fern in her display.
0:09:43 > 0:09:45ANDY GROANS
0:09:46 > 0:09:48Ho, ho, ho.
0:09:53 > 0:09:55There, all done.
0:09:55 > 0:09:56CLOCK CHIMES
0:09:56 > 0:10:00I've got to go. Just time to get back to the museum
0:10:00 > 0:10:02before it opens.
0:10:03 > 0:10:05HE YELPS
0:10:05 > 0:10:07Ooh!
0:10:07 > 0:10:10No, don't go.
0:10:10 > 0:10:12How am I going to get down?
0:10:12 > 0:10:18Um... Hatty's backpack. It's always full of useful things.
0:10:18 > 0:10:20Right.
0:10:20 > 0:10:23Well, it is a rope but it's attached to a rescue balloon.
0:10:23 > 0:10:27They're to help other people find you when you are lost.
0:10:27 > 0:10:29How's that going to help me now?
0:10:29 > 0:10:31Unless...
0:10:31 > 0:10:34I've got an idea. I hope this works.
0:10:36 > 0:10:40Right. Now, if I just pull this...
0:10:42 > 0:10:45It's working! Oh, yes.
0:10:45 > 0:10:47Here we go!
0:10:51 > 0:10:56It's incredible up here. Ho, ho, ho! What a view!
0:11:00 > 0:11:02OK, the clock...
0:11:03 > 0:11:05Where is it again?
0:11:06 > 0:11:09I think I'm going in the right direction.
0:11:11 > 0:11:13Oh, a flock of pterosaurs!
0:11:14 > 0:11:17And they're coming this way.
0:11:21 > 0:11:23Hang on...
0:11:25 > 0:11:28They are going to pop the balloon. Shoo, shoo!
0:11:29 > 0:11:32HE SHOUTS
0:11:32 > 0:11:34Whoa!
0:11:39 > 0:11:44Well, that's one way of doing it. Time to head back!
0:11:59 > 0:12:02CLOCK CHIMES
0:12:24 > 0:12:27CLOCK CHIMES
0:12:44 > 0:12:46Hurry along now.
0:12:50 > 0:12:54We don't want to turn into dinosaurs ourselves, do we?
0:12:57 > 0:12:59This is the diplodocus,
0:12:59 > 0:13:03a fascinating dinosaur that lived 152 million
0:13:03 > 0:13:07years ago and only ate plants, like this giant fern.
0:13:07 > 0:13:09And the odd backpack, too.
0:13:09 > 0:13:13For a while, it was thought to be the biggest dinosaur in the world.
0:13:13 > 0:13:15In fact, it was so big,
0:13:15 > 0:13:18it was able to knock down huge trees to get the ferns behind.
0:13:20 > 0:13:24- Thanks for tidying up, Andy. - Oh, any time, Hatty.
0:13:24 > 0:13:27The fern really does look good, doesn't it?
0:13:27 > 0:13:29And it's bigger than I remember.
0:13:29 > 0:13:32Sh! See you next time.
0:13:44 > 0:13:45# One, two, three, four.
0:13:45 > 0:13:48# Andy's dinosaur adventure
0:13:48 > 0:13:51# Dinosaur, dinosaur adventure. #
