0:01:16 > 0:01:18Hey, Hatty.
0:01:20 > 0:01:21Hatty?
0:01:24 > 0:01:27- Hatty?- Oh, hello, Andy.
0:01:27 > 0:01:30Oh, you've got those rocks I asked for - great.
0:01:30 > 0:01:35Could you put one here...and one over there, please?
0:01:35 > 0:01:38What do you think?
0:01:39 > 0:01:42- What is it?- An iguanodon.
0:01:42 > 0:01:45This was all that was left of him.
0:01:46 > 0:01:49- Why, what happened to the rest of him?- Who knows?
0:01:49 > 0:01:53Perhaps his other bones were washed away in a flood,
0:01:53 > 0:01:57or maybe some other animals took them for food.
0:01:57 > 0:02:00An awful lot can happen in 127 million years, you know.
0:02:00 > 0:02:03Well, it is a long time ago.
0:02:03 > 0:02:05Hey, Hatty, what's this?
0:02:05 > 0:02:08An iguanodon's actual footprint.
0:02:08 > 0:02:10It's only got three toes.
0:02:10 > 0:02:13Which shows this footprint came from one of its back feet,
0:02:13 > 0:02:17- because its front feet had five toes.- Pretty big.
0:02:17 > 0:02:20It certainly is, and this one's not even from an adult.
0:02:20 > 0:02:22- Oh, no, let me. - Oh, no, it's all right.
0:02:22 > 0:02:25I remember when I found this footprint.
0:02:25 > 0:02:28I was hunting for fossils in the mountains of Utah.
0:02:28 > 0:02:31There. All done.
0:02:31 > 0:02:33SHE GASPS I'd better get going!
0:02:33 > 0:02:35The museum opens soon and I've got lots to do.
0:02:35 > 0:02:39Would you mind tidying up before the children arrive?
0:02:39 > 0:02:42Don't worry, leave it to me. I'll tidy everything.
0:02:42 > 0:02:46- Thanks, Andy. I knew I could count on you.- Always!
0:02:48 > 0:02:52I wonder how big my foot is in comparison?
0:03:02 > 0:03:04Ahh, Hatty won't mind.
0:03:08 > 0:03:10Gently.
0:03:14 > 0:03:16Look at the size difference!
0:03:16 > 0:03:20Right, better put it back in case anything goes wrong.
0:03:20 > 0:03:21Oh!
0:03:23 > 0:03:24HE SNEEZES
0:03:24 > 0:03:27Ohh!
0:03:27 > 0:03:31Erm, it's OK, I can just stick them back together with glue.
0:03:31 > 0:03:33CLOCK CHIMES
0:03:37 > 0:03:40SQUAWK! SQUAWK! SQUAWK!
0:03:40 > 0:03:43Even better!
0:03:44 > 0:03:47Time to go on a dinosaur adventure!
0:03:58 > 0:04:00Right, waistcoat...
0:04:00 > 0:04:02gizmo, hat.
0:04:02 > 0:04:05And, last but not least, Hatty's backpack.
0:04:23 > 0:04:26To the time of iguanodon!
0:04:30 > 0:04:32WHOOSHING AND WHIRRING
0:04:58 > 0:05:02I've travelled back in time 127 million years
0:05:02 > 0:05:05to the time of iguanodon!
0:05:07 > 0:05:10Right, I need to find myself an iguanodon
0:05:10 > 0:05:13and make a plastercast of its footprint.
0:05:13 > 0:05:15SOFT PURRING
0:05:18 > 0:05:21That sounds promising!
0:05:36 > 0:05:38LOUDER PURRS
0:05:38 > 0:05:40Huh? Did you hear that?
0:05:45 > 0:05:47Come on, let's take a look.
0:06:06 > 0:06:10Oh, yes! This is exactly the dinosaur I wanted to see!
0:06:10 > 0:06:12A huge iguanodon,
0:06:12 > 0:06:17just like the one in Hatty's display back at the museum.
0:06:18 > 0:06:20I'm going to get closer.
0:06:30 > 0:06:35Look at that! They can go up onto their two legs when they need to.
0:06:41 > 0:06:45Right, let's take a look at their footprints now.
0:07:07 > 0:07:10One, two...three toes!
0:07:10 > 0:07:14Just like the footprint that Hatty had! Perfect.
0:07:14 > 0:07:19Now, all I need to do is to get some plaster to make a copy of it.
0:07:22 > 0:07:25Huh? Hang on a minute, what's going on?
0:07:28 > 0:07:32Whoa, why's the ground shaking?
0:07:32 > 0:07:34HE GASPS
0:07:34 > 0:07:39Oh-ho-ho, look! A whole herd of iguanodons!
0:07:41 > 0:07:44Come on, let's go join them!
0:08:01 > 0:08:04This is incredible! There must be about 100 of them!
0:08:04 > 0:08:06Where are they all going?
0:08:06 > 0:08:10Ah, it says here that they're heading south for the winter
0:08:10 > 0:08:13to keep warm and find fresh food.
0:08:15 > 0:08:18Of course, walking on the beach is so much easier
0:08:18 > 0:08:22than clomping through the forest.
0:08:22 > 0:08:24It's a polacanthus,
0:08:24 > 0:08:27covered in armour just like a big tank!
0:08:28 > 0:08:31This is amazing!
0:08:34 > 0:08:37I've never seen so many dinosaurs before.
0:08:40 > 0:08:46Ah, that was close! These iguanodon are surprisingly fast on two legs.
0:08:46 > 0:08:50You're going the wrong way! You're supposed to be going south!
0:08:50 > 0:08:52I don't know, poor things.
0:08:53 > 0:08:58They may have been big, but they obviously only had tiny brains.
0:08:59 > 0:09:04That's better! Right, now, let's go and find some good footprints.
0:09:11 > 0:09:14This sand is just right!
0:09:14 > 0:09:17It's really wet, so it really holds the shape of the print.
0:09:17 > 0:09:20Excuse me, friend!
0:09:20 > 0:09:22Thank you.
0:09:23 > 0:09:25Too big.
0:09:25 > 0:09:28Too small.
0:09:30 > 0:09:32That one's a polacanthus.
0:09:34 > 0:09:38Five toes, not three, which means that's a front leg.
0:09:40 > 0:09:42Yes! This footprint is perfect!
0:09:42 > 0:09:46OK, now, first of all,
0:09:46 > 0:09:49Hatty's quick-drying plaster powder...
0:09:49 > 0:09:54some water, and I'm going to need a stick, too.
0:09:54 > 0:09:56Ah, this will do.
0:09:56 > 0:10:01If I draw around it, so I've got the right size...
0:10:01 > 0:10:03There we go.
0:10:04 > 0:10:08Now I just pour the water into the plaster powder.
0:10:10 > 0:10:11WIND BLOWS
0:10:11 > 0:10:14That wind's really picking up.
0:10:14 > 0:10:18That should do it. Then I pour it in...
0:10:22 > 0:10:26Oh, make sure it's all filled up.
0:10:27 > 0:10:29And wait for it to...
0:10:29 > 0:10:32Huh? It's dried already!
0:10:32 > 0:10:36It really is quick-drying!
0:10:36 > 0:10:38Look at this!
0:10:40 > 0:10:44Hatty's not going to know the difference. Pop that in the bag.
0:10:45 > 0:10:47There we go, I did it!
0:10:47 > 0:10:50This wind is getting really strong now.
0:10:50 > 0:10:52- CLOCK CHIMES - The clock!
0:10:52 > 0:10:54I've got enough time to get to the clock
0:10:54 > 0:10:57and get back to the museum before it opens.
0:10:57 > 0:10:59SQUELCHING
0:10:59 > 0:11:02I'm stuck in the soft sand!
0:11:03 > 0:11:06What am I going to do now?!
0:11:06 > 0:11:07Hatty's backpack -
0:11:07 > 0:11:11it's always full of the most useful things.
0:11:13 > 0:11:16A picnic blanket? What am I going to do with that?
0:11:16 > 0:11:20It's not as if I'll have tea and cakes with the dinosaurs.
0:11:20 > 0:11:24How am I going to use a picnic blanket...in this windy weather?
0:11:29 > 0:11:31Whoa!
0:11:31 > 0:11:34Yeah! Ha-ha!
0:11:35 > 0:11:38See you later, iguanodons! Woo-hoo!
0:11:40 > 0:11:44Woo-hoo-hoo! Whoa-hoa!
0:11:46 > 0:11:48Coming in to land!
0:11:48 > 0:11:51Time to head back.
0:11:54 > 0:11:56Whoa!
0:11:58 > 0:12:00CLOCK CHIMES
0:12:29 > 0:12:31CLOCK CHIMES
0:12:43 > 0:12:46Right, hurry along now.
0:12:49 > 0:12:52Don't want to turn into dinosaurs ourselves, do we?
0:12:55 > 0:12:59This is the footprint of an iguanodon,
0:12:59 > 0:13:04a vegetarian dinosaur that could stand on two legs if it wanted.
0:13:04 > 0:13:06(And they could run pretty fast, too.)
0:13:06 > 0:13:11It was also one of the very first dinosaurs to ever be found and named.
0:13:13 > 0:13:14Thanks, Andy.
0:13:14 > 0:13:18You must have been working really hard to finish off in here.
0:13:18 > 0:13:23And that footprint looks even better than I remembered!
0:13:23 > 0:13:26See you next time. Ssh!
0:13:39 > 0:13:43- # One, two, three, four! - Andy's dinosaur adventures
0:13:43 > 0:13:48# Dinosaur, dinosaur adventures! #
