0:00:41 > 0:00:43- SOUNDS PUZZLED
0:00:46 > 0:00:50- Ooh, hello. - What a great way to spend a morning.
0:00:50 > 0:00:52- Making a new jigsaw puzzle.
0:00:55 > 0:00:58- All done. Hello, Mr Dinosaur.
0:00:58 > 0:01:00- Look at those teeth.
0:01:01 > 0:01:02- Rargh!
0:01:03 > 0:01:04- Ha-ha-ha.
0:01:04 > 0:01:07- Oh, I'd love to see a real dinosaur.
0:01:07 > 0:01:09- Maybe there's one under the bed.
0:01:09 > 0:01:13- Hmm. No. No dinosaurs here.
0:01:13 > 0:01:16- Oh, none in here either.
0:01:16 > 0:01:19- Why have I never seen a dinosaur?
0:01:19 > 0:01:22- Ha. When you need to know, - go to Ocido.
0:01:34 > 0:01:35- Whee.
0:01:38 > 0:01:39- Hi, Blero.
0:01:39 > 0:01:42- Hi, Blero.- - Hi, Dylan, Sian. What's this?
0:01:43 > 0:01:45- A new hat?
0:01:45 > 0:01:49- It's my bucket. We're going - to the beach to make sandcastles.
0:01:49 > 0:01:51- Would you like to come too?
0:01:51 > 0:01:55- Yes, please. I love the beach.
0:01:55 > 0:01:57- Blero, er, it's this way.
0:01:58 > 0:02:00- Last one there's a jellyfish.
0:02:02 > 0:02:06- We could build a sandcastle there. - Ooh, no, there.
0:02:06 > 0:02:08- Oh, no, over there.
0:02:08 > 0:02:10- Hi, Lolly.
0:02:10 > 0:02:12- Hiya, Lolly.
0:02:13 > 0:02:15- Ooh, what's this place?
0:02:15 > 0:02:19- Hiya, everyone. - It's my new beach cafe.
0:02:19 > 0:02:22- I'm all ready to open up - for the first time.
0:02:22 > 0:02:25- But I can't think of a name - for the place.
0:02:25 > 0:02:28- Hmm, why don't you call it - The Tasty Sock?
0:02:28 > 0:02:31- You could have a big picture - of a sock up there.
0:02:31 > 0:02:35- That might keep everyone away, - Blero.
0:02:35 > 0:02:37- Well, everyone except you.
0:02:39 > 0:02:42- We'll think of a name - while we're building sandcastles.
0:02:42 > 0:02:46- Oh, thanks, Dylan. See you soon.
0:02:46 > 0:02:50- Right. - We could build a sandcastle there.
0:02:50 > 0:02:53- No, there. Ooh, what about there?
0:02:53 > 0:02:54- Or there.
0:02:55 > 0:03:00- We'll build a sandcastle here. - Right by the sea.
0:03:00 > 0:03:03- Oh, you're right, Sian. - This is the perfect place.
0:03:05 > 0:03:06- Dig, dig, dig, dig, dig.
0:03:07 > 0:03:10- Build, build, build. - Dig, dig, dig, dig, dig.
0:03:13 > 0:03:15- My sandcastle's finished.
0:03:15 > 0:03:16- My sandcastle's finished.- - And mine.
0:03:16 > 0:03:19- I've built a monster sandcastle.
0:03:20 > 0:03:22- Oh.
0:03:22 > 0:03:25- Let's decorate them - with shells and pebbles.
0:03:26 > 0:03:27- Great idea, Dylan.
0:03:29 > 0:03:32- Nothing here. Ooh!
0:03:33 > 0:03:34- What's this?
0:03:34 > 0:03:39- Ooh, it's like a rock - but it's a funny shape.
0:03:39 > 0:03:43- It's definitely not a shell.
0:03:44 > 0:03:45- Then what is it?
0:03:45 > 0:03:47- It's a mystery.
0:03:48 > 0:03:53- Let's ask Sim, Sam and Swn. - They'll help us find the answer.
0:03:54 > 0:03:57- Very interesting. - You're right, Dylan.
0:03:58 > 0:03:59- It's not a rock or a shell.
0:04:00 > 0:04:02- It's something very old.
0:04:02 > 0:04:05- Millions of years old.
0:04:05 > 0:04:10- Whoa. That's older - than the oldest sock under my bed.
0:04:10 > 0:04:13- It's called a fossil.
0:04:13 > 0:04:14- A tonsil?
0:04:15 > 0:04:16- Let me explain.
0:04:17 > 0:04:22- Fossils are made when a plant - or an animal falls on soft land...
0:04:22 > 0:04:24- ..and doesn't move again.
0:04:25 > 0:04:27- Usually, somewhere near water.
0:04:27 > 0:04:33- This plant or animal is then covered - over with mud or clay and sand.
0:04:33 > 0:04:38- Over millions of years, - the original object fades.
0:04:38 > 0:04:40- Water dries up.
0:04:40 > 0:04:45- But the minerals form the shape of - the plant or animal that was there.
0:04:45 > 0:04:48- Then this shape goes really hard. - Hard as a rock.
0:04:49 > 0:04:52- So, what you're left with - is a fossil.
0:04:52 > 0:04:57- A rock version of what fell there - millions of years ago.
0:04:57 > 0:04:59- Bala-bala-boom-boom.
0:04:59 > 0:05:05- The fossil of a leaf is the perfect - thing to decorate a sandcastle.
0:05:05 > 0:05:07- I don't think this is a leaf, Blero.
0:05:07 > 0:05:09- I don't think this is a leaf, Blero.- - It's curved.
0:05:09 > 0:05:12- Maybe it's the fossil of a banana.
0:05:12 > 0:05:13- Or a boomerang.
0:05:14 > 0:05:16- I don't think - it's any of those things.
0:05:16 > 0:05:19- Light bulb moment! - Light bulb moment!
0:05:19 > 0:05:23- Maybe it's just a little piece - of something bigger.
0:05:24 > 0:05:26- Ah, yes.
0:05:26 > 0:05:29- Scientists - called palaeontologists...
0:05:30 > 0:05:35- ..dig for fossils and match - the pieces together like a puzzle.
0:05:35 > 0:05:38- Then they can work out - what it used to be.
0:05:38 > 0:05:40- All those millions of years ago.
0:05:42 > 0:05:44- Oh, I'm good at puzzles.
0:05:44 > 0:05:47- We should try to find - the rest of the fossil pieces...
0:05:47 > 0:05:49- ..near where we found this one.
0:05:50 > 0:05:52- I've got just the thing - to help us dig.
0:05:53 > 0:05:56- OK. Let's Oci-go.
0:05:58 > 0:06:02- I found the fossil - somewhere around here.
0:06:02 > 0:06:07- So, let's give my driller, - grab-a-mole, a try then.
0:06:08 > 0:06:09- Who wants to join me?
0:06:09 > 0:06:11- Who wants to join me?- - Oh, me, me, me, me.
0:06:11 > 0:06:12- Me too.
0:06:12 > 0:06:14- No, thanks, I'll stay here.
0:06:15 > 0:06:16- All aboard.
0:06:22 > 0:06:23- Ah, button.
0:06:24 > 0:06:26- Go on, Blero.
0:06:26 > 0:06:27- Yes.
0:06:28 > 0:06:30- Happy hunting.
0:06:35 > 0:06:37- Can any one see any thing?
0:06:38 > 0:06:39- I can see sand.
0:06:40 > 0:06:42- And a worm. Ooh, and some more sand.
0:06:42 > 0:06:44- And another worm.
0:06:45 > 0:06:49- Ha-ha. - Can anyone see any fossil pieces?
0:06:49 > 0:06:52- Oh, there's something up ahead.
0:06:52 > 0:06:53- Look at that.
0:06:58 > 0:07:01- Yep. Another piece of fossil.
0:07:02 > 0:07:04- Ooh, there's another piece.
0:07:04 > 0:07:05- And another one.
0:07:05 > 0:07:09- Well, don't worry. - My grabbers will grab them all.
0:07:10 > 0:07:12- ALARM SOUNDS
0:07:13 > 0:07:17- Oops, sorry. - I pressed the upside-down button.
0:07:25 > 0:07:28- I wonder - how they're doing down there?
0:07:31 > 0:07:33- Rather well it seems.
0:07:35 > 0:07:37- We picked up - all the pieces we could find.
0:07:40 > 0:07:41- I can't tell what it is.
0:07:42 > 0:07:44- The pieces are just in a big pile.
0:07:44 > 0:07:48- We'll have to put them in the - right order to get a true picture.
0:07:48 > 0:07:51- Ha-ha, just like my jigsaw.
0:07:51 > 0:07:54- Come on. Let's get going.
0:07:56 > 0:07:58- Yes, it fits. Look at this.
0:07:59 > 0:08:01- Erm, yeah, that looks good.
0:08:16 > 0:08:19- Ooh. Looks like a big chicken.
0:08:20 > 0:08:25- Oh, oh, dear. This is - more difficult than it looks.
0:08:25 > 0:08:28- These two pieces go together.
0:08:28 > 0:08:32- I've got it. - I know exactly what it is.
0:08:36 > 0:08:39- That goes over there.
0:08:41 > 0:08:43- I can see what it is now.
0:08:43 > 0:08:45- It's a dinosaur.
0:08:47 > 0:08:50- I was looking for a dinosaur before - but I couldn't find one.
0:08:51 > 0:08:54- They lived in Ocido - millions of years ago...
0:08:54 > 0:08:56- ..before the climate changed...
0:08:57 > 0:09:00- ..and made it difficult - for them to live here.
0:09:00 > 0:09:05- The only way we know about them - is from the fossils left behind.
0:09:05 > 0:09:08- So that's why - I've never seen a dinosaur.
0:09:08 > 0:09:12- They all lived a long time ago.
0:09:13 > 0:09:18- Oh, oh, no. The sea's coming in - and washing away our sandcastles.
0:09:18 > 0:09:20- It's going to wash away our fossil.
0:09:21 > 0:09:25- What if we put it somewhere - where everybody could see it?
0:09:26 > 0:09:29- I know exactly the place. Come on!
0:09:30 > 0:09:32- Help me move the fossil.
0:09:37 > 0:09:39- Thank you so much.
0:09:40 > 0:09:44- The fossil is the perfect sign - for my beach cafe.
0:09:44 > 0:09:48- It's given me a great idea - for a name for the place.
0:09:49 > 0:09:50- The Stinky Sock?
0:09:50 > 0:09:54- The Stinky Sock?- - The Hungry Dinosaur.
0:09:54 > 0:09:57- Ha-ha-ha-ha, ah, yes. Ha-ha.
0:09:57 > 0:10:00- We'll eat here - every time we come to the beach.
0:10:00 > 0:10:04- Speaking of which, - it's time for me to go home.
0:10:04 > 0:10:08- There's a delicious sock - waiting for me.
0:10:08 > 0:10:09- Bye-bye, Blero.
0:10:11 > 0:10:15- So, we don't see dinosaurs...
0:10:15 > 0:10:18- ..because they lived - a long time ago...
0:10:18 > 0:10:20- ..and we know about them...
0:10:20 > 0:10:23- ..because there are fossils - left behind to show us.
0:10:23 > 0:10:27- Maybe I should leave my sock - for a long time...
0:10:27 > 0:10:29- ..so it will change into a fossil.
0:10:29 > 0:10:32- Hmm, nah.
0:10:32 > 0:10:35- I don't think so. Yum, yum, yum!
0:10:35 > 0:10:38- Delish!
0:10:38 > 0:10:39- Bye-bye.
0:10:40 > 0:10:41- Bala-bala-boom-boom!
0:10:59 > 0:10:59- .
