0:00:02 > 0:00:04I'm Andy and I work here at the National Museum.
0:00:04 > 0:00:08There's dinosaurs of all shapes and sizes. You should see them.
0:00:08 > 0:00:11Hatty's a collector of things from long ago.
0:00:11 > 0:00:12Come and see the dinosaurs!
0:00:12 > 0:00:15# Ready, steady, go! One, two, three, four!
0:00:15 > 0:00:20# Come on Andy's dinosaur adventures
0:00:20 > 0:00:22# Hey, join the crew
0:00:22 > 0:00:25# Looking at the dinosaurs Collecting something too
0:00:25 > 0:00:27# Yeah, you can come too... #
0:00:27 > 0:00:30The old museum clock takes me back in time
0:00:30 > 0:00:33to when dinosaurs ruled the world!
0:00:33 > 0:00:36Take me to the time of the dinosaurs, I say.
0:00:36 > 0:00:39Hold on tight, shut your eyes and then we fly away.
0:00:39 > 0:00:41# One, two, three, four!
0:00:41 > 0:00:45# Come on Andy's dinosaur adventures
0:00:45 > 0:00:46# Hey, join the crew!
0:00:46 > 0:00:50# Looking at the dinosaurs Collecting something too
0:00:50 > 0:00:52# Yeah, you can come too!
0:00:52 > 0:00:55# Andy's dinosaur adventures
0:00:55 > 0:00:59# Dinosaur, dinosaur adventures! #
0:01:15 > 0:01:20Hello. I work in the dinosaur gallery here in the National Museum.
0:01:20 > 0:01:23Today, there's a brand-new exhibition
0:01:23 > 0:01:27all about what animal life was like in the sea millions of years ago.
0:01:27 > 0:01:29And Hatty, our dinosaur expert,
0:01:29 > 0:01:31has asked me to bring her this sand for her display.
0:01:35 > 0:01:36HE SIGHS
0:01:36 > 0:01:37I feel like I'm underwater!
0:01:38 > 0:01:40Hatty?
0:01:40 > 0:01:42Hatty?
0:01:42 > 0:01:45- SHE HUMS - Oh! You're in a hurry.
0:01:45 > 0:01:47I certainly am.
0:01:47 > 0:01:50Just trying to finish this ammonite display before the museum opens.
0:01:50 > 0:01:53- What's an ammonite? - This is an ammonite.
0:01:53 > 0:01:55Or a model of an ammonite anyhow.
0:01:55 > 0:01:57It looks a bit like a curled-up snake.
0:01:57 > 0:02:01- An ammonite was actually a kind of mollusc.- Oh!
0:02:01 > 0:02:04- Like a snail or a slug? - Or an octopus or a squid.
0:02:04 > 0:02:06Magnifying glass.
0:02:06 > 0:02:10They're all molluscs, but an ammonite was a kind of mollusc
0:02:10 > 0:02:14that lived in shoals and swam through the sea millions of years ago.
0:02:14 > 0:02:17Light brush.
0:02:17 > 0:02:19They came in all shapes and sizes too.
0:02:19 > 0:02:22From ones the size of my eye...
0:02:22 > 0:02:25- Tissue.- Oh.
0:02:25 > 0:02:28..to massive ones...
0:02:28 > 0:02:31the size of you.
0:02:31 > 0:02:33The size of me?!
0:02:33 > 0:02:37So how did they swim about? I can't see any tails or fins on them.
0:02:37 > 0:02:42That's because...this is just part of an ammonite, the shell.
0:02:42 > 0:02:44Millions of years ago,
0:02:44 > 0:02:48there would have been a big slug-like creature living inside the shell
0:02:48 > 0:02:52and it would have jetted along by squirting water out of its body.
0:02:52 > 0:02:55- Wow!- And when they wanted to float,
0:02:55 > 0:02:57they just filled themselves up with gas.
0:02:57 > 0:03:01And when they wanted to sink, they just let it all out again.
0:03:01 > 0:03:03- Ah!- That way they could rise and fall as they liked.
0:03:03 > 0:03:06SHE GASPS I'd better be going! The doors open soon!
0:03:06 > 0:03:09I've still got lots to do! Can I leave you to sort out the sand?
0:03:09 > 0:03:12- Leave it to me, Hatty.- Thanks, Andy. HE LAUGHS
0:03:32 > 0:03:34Lived in here?!
0:03:42 > 0:03:44Oh, no!
0:03:44 > 0:03:46- HE TUTS - Oh!
0:03:46 > 0:03:48AMMONITE SHATTERS
0:03:48 > 0:03:49Oh, no!
0:03:49 > 0:03:51What am I going to do?!
0:03:51 > 0:03:53HE SIGHS
0:03:53 > 0:03:56Hatty spent ages making that!
0:03:56 > 0:03:57I could make a new one.
0:03:57 > 0:04:00There's not enough time! CLOCK CHIMES
0:04:03 > 0:04:05BIRD SQUAWKS
0:04:10 > 0:04:13Time to go on a dinosaur adventure!

0:05:27 > 0:05:31Oh! And look! Pterosaurs!
0:05:32 > 0:05:34And I'm on a beach.
0:05:34 > 0:05:36I might find an ammonite shell washed up somewhere.
0:05:37 > 0:05:39PTEROSAUR SHRIEKS
0:05:43 > 0:05:46Well, there are plenty of shells on this beach.
0:05:46 > 0:05:50Conch shells, clam shells,
0:05:50 > 0:05:52mussel shells...
0:05:52 > 0:05:56and even turtle shells!
0:05:56 > 0:05:58With the turtles still in them!
0:05:59 > 0:06:05Look at that! Baby turtles heading for the sea for the very first time!
0:06:09 > 0:06:12Good luck! Enjoy your first swim.
0:06:14 > 0:06:18Hmm. There doesn't seem to be any ammonite shells around here.
0:06:20 > 0:06:22What's that?!
0:06:22 > 0:06:24BEEPING
0:06:24 > 0:06:27Whoa! Look at them jump!
0:06:28 > 0:06:29BEEPING
0:06:29 > 0:06:30HE LAUGHS
0:06:30 > 0:06:32Baby ichthyosaurs!
0:06:34 > 0:06:37And it says here that they used to eat ammonite shells.
0:06:37 > 0:06:40If there are no ammonite shells on the beach,
0:06:40 > 0:06:43I've got to go in there. Time for a swim.
0:07:10 > 0:07:14Whoa! Did you see all those ammonites down there?!
0:07:14 > 0:07:17I just need to find one exactly like Hatty's.
0:07:17 > 0:07:18BIRD SQUAWKS
0:07:32 > 0:07:34A pterosaur!
0:07:34 > 0:07:37That was close. I think he must be fishing.
0:07:42 > 0:07:44I'm going to try looking for a shell closer to shore.
0:08:04 > 0:08:06I've found one! Yes!
0:08:06 > 0:08:08- All I need to do... - GROWLING

0:08:54 > 0:08:58The ammonite! Now all I have to do is head back to the museum. Right.
0:09:00 > 0:09:03PTEROSAURS SCREECH
0:09:03 > 0:09:07OK, I just need my badge, which is in Hatty's backpack.
0:09:07 > 0:09:10Where's Hatty's backpack?
0:09:13 > 0:09:15Oh, no!
0:09:19 > 0:09:22It's one of those swimming dinosaurs again!
0:09:22 > 0:09:23And he's got Hatty's backpack!
0:09:23 > 0:09:26Hey! Leave that alone! That doesn't belong to you!
0:09:26 > 0:09:30- GROWLING - Great! And here comes another one!
0:09:31 > 0:09:33She's never going to believe me
0:09:33 > 0:09:37if I tell her I've lost her bag in a game of dino tug-of-war.

0:09:58 > 0:10:03It turns out these big dinosaurs are called...eustreptospondylus.
0:10:05 > 0:10:09They're five metres long! And they're meat-eaters too!
0:10:16 > 0:10:18And this one...is after me!
0:10:38 > 0:10:42Huh? The beach is covered with...pterosaurs!

0:11:14 > 0:11:16I know exactly where I am.
0:11:16 > 0:11:18I'm in trouble.
0:11:21 > 0:11:23Unless...
0:11:26 > 0:11:30If eustreptospondylus likes catching flying things...
0:11:30 > 0:11:33like those pterosaurs up there...
