0:00:22 > 0:00:25Here comes William Whiskerson
0:00:25 > 0:00:27in his amazing travelling globe.
0:00:32 > 0:00:34Greetings, adventurers.
0:00:34 > 0:00:39I am William Whiskerson, the famous mouse explorer.
0:00:41 > 0:00:44William is on a beach.
0:00:44 > 0:00:48But which part of the United Kingdom is he in today?
0:00:48 > 0:00:52Cheesephone, reveal my location!
0:00:56 > 0:01:00The Cheesephone shows William, where he is on a map of the world.
0:01:04 > 0:01:07Hello, William. Today, you're in the south of England.
0:01:07 > 0:01:10In a town called Lyme Regis.
0:01:10 > 0:01:12The cliffs and beaches of Lyme Regis
0:01:12 > 0:01:15are part of an area known as the Jurassic Coast.
0:01:15 > 0:01:19The area is full of important clues that tell us
0:01:19 > 0:01:25how the Earth has changed over 185 million years.
0:01:25 > 0:01:30Oh, I've got a message coming through on my Cheesephone!
0:01:30 > 0:01:33Hello, William. This is Cameron and I'm Kedisha.
0:01:33 > 0:01:35Welcome to Lyme Regis.
0:01:35 > 0:01:38Would you like to come on a fossil hunt with us?
0:01:38 > 0:01:41That sounds amazing!
0:01:41 > 0:01:44Lock the location, Cheesephone.
0:01:46 > 0:01:48The map shows William
0:01:48 > 0:01:51where to meet Kedisha and Cameron.
0:01:51 > 0:01:54Explorers away!
0:01:55 > 0:01:59Pleased to squeak you, Kedisha and Cameron.
0:01:59 > 0:02:01BOTH: Pleased to squeak you, William.
0:02:01 > 0:02:06What are all these people doing here?
0:02:06 > 0:02:08Swimming and playing.
0:02:08 > 0:02:10And building castles and sunbathing.
0:02:10 > 0:02:13Lyme Regis has lovely beaches,
0:02:13 > 0:02:17which is why lots of people like to go there on holiday.
0:02:17 > 0:02:20Whilst looking around the town,
0:02:20 > 0:02:24William notices a funny shape that keeps appearing.
0:02:24 > 0:02:26It appears on buildings,
0:02:26 > 0:02:27in the walls,
0:02:27 > 0:02:30even on the streetlights!
0:02:30 > 0:02:31Hey, you two,
0:02:31 > 0:02:34look at that strange shape!
0:02:34 > 0:02:37I've never seen anything like that.
0:02:37 > 0:02:39It looks like a snail.
0:02:39 > 0:02:42That isn't a snail, that's an ammonite.
0:02:42 > 0:02:44An ammonite?
0:02:44 > 0:02:46- Yes.- What's an ammonite?
0:02:46 > 0:02:48A type of a fossil.
0:02:48 > 0:02:52Oh, a fossil.
0:02:52 > 0:02:55A fossil is a special rock that holds a secret.
0:02:55 > 0:02:59The explorers decide to ask the Cheesephone more about them.
0:02:59 > 0:03:01Cheesephone,
0:03:01 > 0:03:03can you tell us about fossils?
0:03:03 > 0:03:05Certainly, William.
0:03:05 > 0:03:08Here's the story of how a fossil is made.
0:03:08 > 0:03:10This is an ammonite.
0:03:10 > 0:03:14Ammonites were once sea creatures with squid-like tentacles
0:03:14 > 0:03:16and a curly shell like a snail.
0:03:16 > 0:03:19They lived at the same time as dinosaurs.
0:03:19 > 0:03:24When an ammonite died, its shell would lie at the bottom of the sea.
0:03:24 > 0:03:26Layers of mud covered the shell.
0:03:26 > 0:03:30This protected it and stopped it from crumbling away.
0:03:30 > 0:03:34Over time, the mud and shell hardened and turned into rock.
0:03:34 > 0:03:37As this happened, the shell became a fossil.
0:03:37 > 0:03:42Fossils can be found all around the coast of Lyme Regis.
0:03:42 > 0:03:44Thank you, Cheesephone.
0:03:44 > 0:03:48ALL: Explorers away!
0:03:48 > 0:03:52The explorers decide to find out more about fossils
0:03:52 > 0:03:54and travel to anther part of the beach
0:03:54 > 0:03:57where they meet Chris, the fossil expert.
0:03:57 > 0:04:00Oh! Pleased to squeak you, Chris.
0:04:00 > 0:04:02Pleased to squeak you, William.
0:04:02 > 0:04:04What we're going to do
0:04:04 > 0:04:06is look to see if we can find
0:04:06 > 0:04:07fossils on the beach.
0:04:07 > 0:04:09And fossils are the remains
0:04:09 > 0:04:11of creatures that lived in Lyme
0:04:11 > 0:04:13about 200 million years ago.
0:04:13 > 0:04:15We have to look carefully
0:04:15 > 0:04:17in among the small rocks.
0:04:17 > 0:04:20Aw, that sounds really exciting.
0:04:20 > 0:04:23Explorers away!
0:04:23 > 0:04:26Right! Let's have a look to see what we can find.
0:04:26 > 0:04:31The explorers set off to hunt for fossils.
0:04:37 > 0:04:40You know the sparkly bits, they're crystals.
0:04:40 > 0:04:42They search the beach for clues
0:04:42 > 0:04:46to see if they can find any strange patterns or shapes
0:04:46 > 0:04:48on the surface of the rocks.
0:04:48 > 0:04:49I've got one.
0:04:49 > 0:04:51These could be fossils.
0:04:51 > 0:04:54- This...- Yeah, if you want...
0:04:54 > 0:04:56Can't find any here.
0:05:00 > 0:05:04Where should we put this one for our collection?
0:05:04 > 0:05:08- I'll tell you what, shall we put them right there?- OK.
0:05:08 > 0:05:12Kedisha and Cameron find another fossil.
0:05:12 > 0:05:15Can you see the shape in the rock?
0:05:16 > 0:05:19Aaa! Ha! Ha!
0:05:19 > 0:05:22Found one! He-he.
0:05:22 > 0:05:25I think it's an ammonite, he-he.
0:05:28 > 0:05:31Can you show us some fossils you've found on this beach?
0:05:31 > 0:05:33Certainly, William.
0:05:33 > 0:05:36One of the most well-known fossils from Lyme
0:05:36 > 0:05:37are these coiled shells.
0:05:37 > 0:05:39I know you found some of those.
0:05:39 > 0:05:43- Can you remember their name? - CHILDREN: Ammonites.
0:05:43 > 0:05:44Ammonites.
0:05:44 > 0:05:47But when people see a coily shell,
0:05:47 > 0:05:49they think they were a type of snail.
0:05:49 > 0:05:53But they are not snails. They're way more exciting.
0:05:53 > 0:05:55They're related to squids and octopuses
0:05:55 > 0:05:58and cuttlefish and things like that.
0:05:58 > 0:06:01They've got tentacles for catching their food.
0:06:01 > 0:06:04And they've got a beak in the middle to bite food
0:06:04 > 0:06:07and very well-developed eyes and this coily shell.
0:06:07 > 0:06:10And when they die, all the flesh rots away
0:06:10 > 0:06:13and all we find are the shells of them.
0:06:13 > 0:06:15And lots of different types.
0:06:15 > 0:06:17- Just like those ones. - Just like those ones.
0:06:17 > 0:06:19We don't just find ammonites,
0:06:19 > 0:06:22we find bigger things as well.
0:06:22 > 0:06:26But less commonly, we find parts of this creature.
0:06:26 > 0:06:30It's a creature that's not alive today - an ichthyosaur.
0:06:30 > 0:06:36And we find not the soft parts, but we find the hard bones from inside.
0:06:36 > 0:06:39And one of the nicest bits to find are the jaws at the front.
0:06:39 > 0:06:45The most common bits that we find of ichthyosaurs are the backbone,
0:06:45 > 0:06:48- the spine.- The backbone, down there, like we have one.
0:06:48 > 0:06:51Yeah. Goes all the way down the body
0:06:51 > 0:06:56and an ichthyosaur would have had about 180 bones like that.
0:06:56 > 0:07:00Hunting for fossils along the beach can be lots of fun.
0:07:00 > 0:07:04But it's important that you always have a grown-up with you.
0:07:04 > 0:07:08Rocks from the cliffs that run along the beach can become loose,
0:07:08 > 0:07:12so you mustn't get too close.
0:07:12 > 0:07:15Fancy going to the museum to see some bigger fossils?
0:07:15 > 0:07:17CHILDREN: Yes, please.
0:07:17 > 0:07:19That sounds amazing.
0:07:19 > 0:07:22Explorers away!
0:07:24 > 0:07:28Inside the museum, the explorers get to have a closer look
0:07:28 > 0:07:31at some big fossils.
0:07:31 > 0:07:33You found small fossils on the beach
0:07:33 > 0:07:35and I've told you a bit about them
0:07:35 > 0:07:38and I said we'd see bigger fossils here.
0:07:38 > 0:07:41This is a big skeleton of an ichthyosaurus.
0:07:41 > 0:07:42What, an itchysaur?
0:07:42 > 0:07:45Not an itchysaur. An Ichthyosaur.
0:07:45 > 0:07:48Ichthyosaur means fish lizard.
0:07:48 > 0:07:51Can you guess at all what this is?
0:07:51 > 0:07:54What do you think? Here's a clue.
0:07:54 > 0:07:57It's something a dinosaur would leave behind
0:07:57 > 0:07:59after it had gone to the toilet.
0:07:59 > 0:08:01- Poo. - BOTH: Poo.
0:08:01 > 0:08:03Dinosaur poo!
0:08:03 > 0:08:07There you go. That's real fossil poo.
0:08:07 > 0:08:09It's about 200 million years old
0:08:09 > 0:08:11and it doesn't smell at all now.
0:08:11 > 0:08:15Yes, explorers! Even poo can be fossilised.
0:08:15 > 0:08:19It can reveal what dinosaurs ate millions of years ago.
0:08:21 > 0:08:25After the museum, the explorers have a treat on the beach.
0:08:25 > 0:08:28This fossil hunting has made me hungry!
0:08:28 > 0:08:29Me too.
0:08:29 > 0:08:30Yeah, and me.
0:08:32 > 0:08:36I've had a great time hunting for fossils with you two.
0:08:36 > 0:08:38So have we.
0:08:38 > 0:08:40I have a present for you.
0:08:40 > 0:08:41Oh, what is it?
0:08:41 > 0:08:44- It's an ammonite.- Ah!
0:08:44 > 0:08:48Thank you! My very own ammonite.
0:08:48 > 0:08:50Goodbye, explorers.
0:08:50 > 0:08:51BOTH: Goodbye, William.
0:08:51 > 0:08:54ALL: Explorers away!
0:08:56 > 0:08:59Can you remember where William went today?
0:08:59 > 0:09:04William visited his friends Kedisha and Cameron in Lyme Regis.
0:09:04 > 0:09:08They learned all about fossils.
0:09:08 > 0:09:12And went on the beach to meet Chris, a fossil expert.
0:09:12 > 0:09:15Can you remember what they did?
0:09:15 > 0:09:17They went hunting for fossils.
0:09:17 > 0:09:22They then went to the museum and saw something very special.
0:09:22 > 0:09:25Can you remember what it was?
0:09:25 > 0:09:27Some dinosaur poo!
0:09:28 > 0:09:31At the end of his adventure, he was given a fossil
0:09:31 > 0:09:35and even had a yummy ice cream on the beach.
0:09:35 > 0:09:39Time to fly, explorers. We're off on another adventure!
0:09:41 > 0:09:42See you soon, William!
