0:00:02 > 0:00:04I'm Andy, and I work here at the National Museum.
0:00:04 > 0:00:08We've got dinosaurs and ice age beasts. You should see them!
0:00:08 > 0:00:10Jen is my assistant, Mrs Pickles runs the show.
0:00:10 > 0:00:14- Come on my adventure! - Ready, steady go...
0:00:14 > 0:00:15One, two, three, four!

0:00:21 > 0:00:25# Travel back in time and discover something new
0:00:25 > 0:00:27# Yeah, you can come too! #
0:00:27 > 0:00:29You'll see woolly mammoths, dinosaurs, cavemen and more
0:00:29 > 0:00:33When I jump into the old museum clock to explore.
0:00:33 > 0:00:35"Take me off to prehistoric times," I say.
0:00:35 > 0:00:37Hold on tight, shut your eyes...
0:00:37 > 0:00:39And then we fly away!

0:01:04 > 0:01:06HE WHISTLES
0:01:23 > 0:01:28Hi! I'm Andy. I run the Prehistoric Gallery here at the National Museum.
0:01:28 > 0:01:30I love my job.
0:01:30 > 0:01:33Today I've been working on a display about a colossal dinosaur.
0:01:33 > 0:01:37I've got something in here for it. Come on, I'll show you.
0:01:43 > 0:01:45- Hi, Jen!- Hi, Andy.
0:01:45 > 0:01:47What is this you're working on?
0:01:47 > 0:01:50This display is all about Argentinosaurus,
0:01:50 > 0:01:54one of the largest dinosaurs ever discovered.
0:01:54 > 0:01:55It doesn't look that big to me.
0:01:55 > 0:01:59- This is just the bone at the bottom bit of its leg.- Wow!
0:01:59 > 0:02:03In that case, it would have been absolutely enormous!
0:02:03 > 0:02:05Yeah, it was.
0:02:05 > 0:02:07But they started life teeny-tiny,
0:02:07 > 0:02:10in little nests a bit like this.
0:02:10 > 0:02:11A nest?
0:02:11 > 0:02:16Yes, Argentinosaurus hatched from an egg not much bigger than my hand.
0:02:16 > 0:02:20But then they grew into a massive dinosaur.
0:02:20 > 0:02:22- Wow!- Look at this.
0:02:29 > 0:02:30HE SIGHS
0:02:30 > 0:02:36This is a piece of fossilised Argentinosaurus eggshell.
0:02:36 > 0:02:41Mrs Pickles found it in South America. It's 95 million years old.
0:02:41 > 0:02:42Oh, wow!
0:02:42 > 0:02:47What an incredible dinosaur! I want to work out just how big they grew.
0:02:47 > 0:02:48Come on.
0:02:48 > 0:02:50Oh... Um...
0:02:59 > 0:03:01Here we go.
0:03:01 > 0:03:05I've calculated a fully grown Argentinosaurus would have been
0:03:05 > 0:03:07just over 30 metres head to tail,
0:03:07 > 0:03:11so that's as long as three double-decker buses.
0:03:13 > 0:03:15- That's so clever!- Not really.
0:03:15 > 0:03:18I worked out the dimensions of the leg bone,
0:03:18 > 0:03:21then extrapolated the data with basic vector graphics.
0:03:21 > 0:03:23Right!
0:03:23 > 0:03:24DOOR OPENS Oh!
0:03:24 > 0:03:28- Ah! Hello, you two. - BOTH: Hello, Mrs Pickles.
0:03:28 > 0:03:29I want to see
0:03:29 > 0:03:32how the Argentinosaurus display is coming along.
0:03:32 > 0:03:35- It will be ready for the morning. - Wonderful.
0:03:35 > 0:03:38You will be careful with my eggshell, won't you?
0:03:38 > 0:03:43- It's 95 million years old, you know. - We'll take extra-special care of it.
0:03:43 > 0:03:46I knew I could count on you both. See you in the morning.
0:03:46 > 0:03:48Goodnight!
0:03:48 > 0:03:51Right, Jen, let's go and put that eggshell into the nest.
0:03:54 > 0:03:59- It's gone!- Where did it go? - It was just here!
0:03:59 > 0:04:03We can't have lost it already! Mrs Pickles will be so upset.
0:04:03 > 0:04:05What are we going to do?
0:04:05 > 0:04:08We need to search the whole of the museum from top to bottom.
0:04:08 > 0:04:12The museum is huge! We're never going to have enough time.
0:04:12 > 0:04:14CLOCK CHIMES

0:04:26 > 0:04:29Time to go on a prehistoric adventure!
0:04:29 > 0:04:32But, Andy, where are you going to find a...?
0:04:32 > 0:04:34..nother eggshell?

0:05:53 > 0:05:56THUDDING
0:05:58 > 0:06:00It's not an earthquake.
0:06:00 > 0:06:03It's an Argentinosaurus-quake!
0:06:03 > 0:06:05Whoa!
0:06:06 > 0:06:08Look at the size of her!
0:06:08 > 0:06:12She's so tall she's almost scraping her head on the sky.
0:06:12 > 0:06:14DEEP ROARING
0:06:14 > 0:06:17There's a whole parade of Argentinosaurus here!
0:06:17 > 0:06:19They're immense!
0:06:21 > 0:06:23There must be some eggs nearby.
0:06:25 > 0:06:26Excuse me!
0:06:26 > 0:06:30Where do you lay your eggs? Excuse me...
0:06:30 > 0:06:33They're never going to hear me all the way down here.
0:06:33 > 0:06:36I need to get close to their ears.
0:06:38 > 0:06:42That is a long way up. How am I going to do that?
0:06:42 > 0:06:44DEEP ROARING

0:07:39 > 0:07:44It's a good thing Argentinosauruses aren't scared of heights.
0:07:44 > 0:07:47They have to eat so much
0:07:47 > 0:07:49that they don't bother to chew their food.
0:07:49 > 0:07:52They just gulp it down in one go.
0:07:54 > 0:07:59Excuse me, Argentinosaurus! Could you tell me where you lay your eggs?
0:07:59 > 0:08:01GROWLING
0:08:01 > 0:08:03Oh! Here she comes.

0:09:07 > 0:09:09I'd love to take you back with me, but...
