00:03There is something missing from our world.
00:07The amazing animals that time has left behind.
00:13But what if we could bring them back?
00:16What if extinction didn't have to be forever?
00:25We're going back in time on a safari with a difference.
00:28As wildlife adventurer Nigel Marvin plunges into prehistory
00:33to rescue creatures on the brink of extinction.
00:37His plan is to bring them back to the safety of the present
00:41and give them a second chance.
00:44This time, Nigel is going back 300 million years
00:48to a time long before the dinosaurs when insects ruled the world.
00:53His goal is to rescue some of the largest
00:56and most dangerous creepy crawlies in history.
01:01Welcome to the ultimate wildlife sanctuary.
01:07Welcome to Prehistoric Park.
01:23Prehistoric Park's mission to bring back extinct animals
01:27has so far been a big success.
01:32The park's elephants now live with a hairy Ice Age cousin.
01:39A herd of hungry titanosaurs roam freely,
01:42and a bad-tempered triceratops needs a lot of attention.
01:50These are just a few of the park's current residents,
01:54and there are plenty more to come.
01:59Right now, while Nigel plans his next prehistoric collecting trip,
02:04the rest of the team are having a bit of trouble
02:07with Prehistoric Park's breeding program.
02:10Now, do it yet, too. Stay there.
02:12Go on. Hey!
02:15There are either too many babies,
02:18or too few.
02:23In his last adventure,
02:26Nigel and his team went back in time 10,000 years
02:29to the plains of South America.
02:32Back then, sabre-toothed cats were on the very brink of extinction.
02:38Nigel managed to rescue a young male,
02:41and a female that had just lost her cub to starvation.
02:56Now, both animals have fully recovered,
02:58and head vet Suzanne wants them to breed.
03:02The trouble is, the female is proving to be a very fussy feline.
03:10We want them to breed, and it's just not working.
03:13She is so aggressive to him at the moment.
03:16I think if we put them together, she would kill him.
03:19I mean, he's really just like an annoying little teenager,
03:22and she's a nice, sensible older woman,
03:25and she is not interested in being with him.
03:28To get them started,
03:30the lucky couple have been put into a special breeding enclosure.
03:33The idea is to keep them close together
03:35so they can get to know each other without fighting.
03:39But so far, it's not working.
03:42I've been doing some research on breeding large cats in captivity,
03:45and I've got an idea about what we can do.
03:48I think we need a bit of romance.
03:50So, just wait.
03:58Nigel has been fascinated with insects and other invertebrates since he was a boy.
04:03Now he's planning to bring back some prehistoric bugs from extinction.
04:08To get it right, first he needs to know exactly where and when to go
04:13to find the creatures he's looking for.
04:15And there's a clue waiting on the remote Scottish island of Arran.
04:27The rocks of Arran date back 300 million years, to a time long before the dinosaurs,
04:33when the world was home to a very different kind of giant.
04:39Nigel has come all this way to study some faint marks in the rock.
04:45These are the fossilised tracks of a creature called Arthropleura.
04:49A primitive arthropod, much like modern millipedes and centipedes, except for one thing.
04:55It grew as big as a man.
05:00Other fossils show that Arthropleura was far from alone.
05:04Giant scorpions and dragonflies were just some of the amazing creatures
05:08that shared the muggy swamps of prehistoric Scotland.
05:14It's mind-boggling what happened through time 300 million years ago.
05:18This was right on the equator.
05:19It was a swamp teeming with giant insects.
05:23I've got to go back here. This is so exciting.
05:27The specimens we can catch for prehistoric park.
05:30Giant dragonflies, huge scorpions, maybe even a centipede that's as big as I am.
05:43With the exact time and place coordinates of his mission confirmed,
05:47Nigel heads back to the park to get ready.
05:50What he doesn't realise is that he's driving straight into a major emergency.
05:57What, Nigel? Get out of the T-Rex enclosure now!
06:02T-Rex Matilda has broken into her brother Terence's enclosure.
06:06Terence wants her up.
06:08When you're a T-Rex, family argument is not a good idea.
06:15When Nigel brought back the two T-Rex from the late Cretaceous period,
06:20they were young and some might even say cute.
06:32Now, though they're still not fully grown, they're very big and very dangerous.
06:42Matilda is the more aggressive of the two and is easily getting the better of her brother.
06:48Bob decides to dart her first.
07:02The dark hits home.
07:04But there's a problem.
07:06The reptiles' tranquilizers take time to work.
07:19Some dinosaurs are known to have been cannibals.
07:23For Terence, Bob's dart may have come too late.
07:32That'll be Nigel, then.
07:37Like most modern predators, Matilda can't resist a moving target.
07:44The plan works.
07:46There's a catch.
07:47Now she's after Nigel.
07:57There's enough to go now.
08:03Get in.
08:05There we go.
08:20Come on, Matilda.
08:23That tranquilizer drug must be working now.
08:26You must be tired.
08:27Come on.
08:29Go on, go over.
08:39Having stopped the fight, Nigel sets off on his prehistoric insect hunt.
08:45With a male T-Rex so badly wounded, it's a tricky time to go,
08:50but Terence is in good hands, and I've seen reptiles recover from horrendous injuries,
08:55so hopefully he's going to be okay.
08:57Nigel's mission will take him back 300 million years
09:01to a time known as the Carboniferous,
09:04further back than he's ever been before.
09:08At that time, the world was a very different place.
09:12Dinosaurs, birds and mammals had not yet evolved.
09:16Scotland was a hot, boggy swan from the equator,
09:19full of primitive fish, amphibians and giant insects.
09:26But Nigel's destination is so far back in time
09:29that he has no way of knowing what dangers he may have to face.
09:36Oh, Moniferous.
09:38Here we come.
09:55Star, please.
09:59What a star.
10:01Oh.
10:05Got our coordinates a bit wrong here.
10:07It's meant to be an island of dry land.
10:10Could have been worse, I suppose.
10:19What a great start. Broken down vehicle.
10:21Up to my knees in slime.
10:25Look at this place.
10:28Look at this place.
10:30Magical.
10:34The forest seems strangely quiet.
10:39But in a prehistoric swamp, you never know what's just around the corner.
10:55Back at the park, Suzanne's vet skills are being tested to the limit.
11:00Terence has lost a lot of blood and is in a critical condition.
11:04Okay.
11:05Now, Suzanne has got to save a very sick dinosaur.
11:09Something they didn't teach her in vet school.
11:13Support his head, watch it.
11:15Gentle.
11:16Okay, that's it, that's it.
11:17Okay.
11:19The most threatening injury is a massive gash on the T-Rex's face.
11:24It's really deep.
11:26Fossils show many examples of face bites in carnivorous dinosaurs.
11:31In a fight, the head was a popular target.
11:37Often with reptiles, you'd use staples rather than stitching them.
11:40But I've chosen not to because we'd have to re-anaesthetise them to take the staples out and we don't
11:44want to do that.
11:45It's important with reptile wounds that we actually stitch them with the skin edges sticking out or being averted.
11:51If they're nice and even, it means the skin edges can grow in and they get horribly infected.
11:55So, it's a bit difficult, but we're going to give that a go.
12:00Thanks.
12:01I guess the biggest risk now is infection.
12:03We'll just have to see how it goes, because we don't really want to use antibiotics if we can help
12:06it.
12:08For Terence, the next 24 hours are critical.
12:15It's not an easy option.
12:16300 million years ago, oxygen levels in the air were almost twice what they are today.
12:21Scientists believe that this may be the reason that insects then were so large.
12:26But so far, Nigel hasn't seen anything, big or small.
12:30Some butterflies have territories at the treetops.
12:33Maybe the dragonflies do.
12:34I've got to get up there.
12:38It's not an easy option.
12:41Prehistoric plants like this one grew to heights of 150 feet and had no branches.
12:47It's a tricky climb.
12:53Over millions of years, this magnificent prehistoric forest will turn into the coal that we burn today.
13:01But right now, it's still a beautiful sight.
13:11Oh, just a sea of green for as far as you can see.
13:16And it's mind-boggling what's going to happen here over the next 300 million years.
13:21Already the climate's changing.
13:22And this Carboniferous swampland, it's diminishing.
13:26In another 50 million years, there'll be conifers here.
13:29And after that, there'll be ice.
13:31The most incredible thing, in 300 million years, right on this spot, well not right here, 150 feet below me,
13:38there could be a fish and chip shop in Glasgow, Scotland.
13:43And look, coming out there from the trees.
13:47Oh, just as I thought.
13:49Oh, straight at me.
13:54A giant dragonfly.
13:56You can see the sun glistening of its wings.
13:59And down below there, it's hard to see through the trees, but there's chinks of shiny, reflective water.
14:06And I think that's the place to go. That's where they'll be laying their eggs.
14:09That's where their larvae will grow up.
14:11That's where they'll hunt prey as well.
14:13And what I've got to do is get down there, get down to water, to find the dragonflies I'm after.
14:19He's got an easier job getting down than me.
14:22All right.
14:32It's all very well collecting giant insects, but you've got to have somewhere to put them.
14:37I hate to say it, lads, but we need to get a shift down here.
14:40Back in the 21st century, park keeper Bob has got a team building a new high-tech bug house.
14:47Now, this is going to be the new insect house.
14:49It needs to be a fair size with a fair bit of headroom for the flying insects.
14:53And also, I'm having to make it airtight to create a special atmosphere,
14:57which means that the doors have got to be airtight as well,
14:59because we don't want to lose that atmosphere every time the doors open and close.
15:04Well, what's he doing down here?
15:07I don't know why, but for some reason the titanosaurs just can't settle at the other end of the park.
15:13They're looking for something. I don't know what.
15:16I thought I had an idea.
15:19The titanosaurs have broken out of every enclosure Bob has built.
15:23Now they roam freely, causing trouble wherever they go.
15:27I should like these sight-guard leaves.
15:30We know they were around in his gear.
15:34Great. Great. Let's see if this does the trick.
15:37Eh? Eh? Is this what you're after?
15:47Obviously not.
15:49I don't know what's the matter with them.
16:02In his search for the ultimate dragonfly,
16:06Nigel moves deeper and deeper into the swamps of prehistoric Scotland.
16:16Something big moving in here, guys.
16:19Look, there's a trail of bubbles disappearing off there.
16:25There's something moving under the water.
16:35It seems there are plenty of things in this swamp bigger than dragonflies.
16:41Can you hear that?
16:43There's something big.
16:44It is moving.
16:49It's so far.
17:07Look at that.
17:09It's an Arthur pleura.
17:10Wow.
17:11What a magnificent creepy crawly.
17:14Remember we saw the tracks of this.
17:15Hey!
17:16That rearing up is obviously a defensive reaction.
17:19I've been sprayed by modern millipedes.
17:21They can secrete cyanide.
17:23That smells of almonds.
17:24I've had that in my eyes.
17:25And that really hurts.
17:27And nobody knows anything about these.
17:28Of course, nobody's seen a living one.
17:31They've only seen the fossils.
17:33Nobody's even too sure whether this is a predator or a vegetarian.
17:38And it must be about 10 feet.
17:40And those huge mandibles, those huge mouth parts.
17:44I'm overjoyed by this.
17:46What a specimen for prehistoric park.
17:48If we can catch it, it's relaxing.
17:51I've got to be so careful here.
17:54If it just relaxes and goes down, maybe I can make a lunge.
17:58Whoa!
17:59That's what I need.
18:00Come on, relax.
18:02Relax.
18:03Relax.
18:06That thing is so fast.
18:23Back at prehistoric park, head vet Suzanne is putting her saber tooth breeding plan into action.
18:29Hi.
18:31She's having their pens altered in an effort to get some romance into the air.
18:37What we're doing here is called environment enrichment.
18:39And what we're trying to do is make this much more interesting, this enclosure,
18:43and mimic the natural surroundings of the saber tooth cat.
18:47We're hoping that's going to make them more comfortable, more relaxed with one another.
18:50And hopefully that's going to make her much less aggressive towards him.
18:54And hopefully it will mean that they're going to breed successfully and we'll get our first saber tooth cubs.
19:07On the other side of the park, head keeper Bob is busy trying to solve the problem of the restless
19:13titanosaurs.
19:14Some nice rounded stones.
19:18I want to give them to the titanosaurs.
19:23Yeah.
19:25We might have found that problem.
19:27A friend of Nigel's, a paleontologist, has sent us some photographs.
19:33Here I'll show you.
19:36And it appears that the titanosaurs used to eat stones.
19:41Now that's not actually as balmy as it sounds. Ostriches do.
19:44Here look, have a look.
19:46Fossils of large plant-eating dinosaurs have been found with stones in their stomachs.
19:51One theory is that they ate stones to help grind up tough plant matter in their gut.
19:58It's a nice idea, but will the titanosaurs really fancy a mouthful of rocks?
20:08The arthaplora's long gone.
20:11We can't give up. I mean, slurping mud, it's stinking hot, but swamps, they're a paradise for me, teeming with
20:18life.
20:19And we've just got to catch some of it.
20:21Just imagine the insect now.
20:24That prehistoric part.
20:27Just to taunt us.
20:29Look at this.
20:31The arthaplora tracks.
20:33And these are just like the ones in Scotland, just like the ones we saw on the Isle of Arrows.
20:38And we're about the right place, about the right time.
20:40This could be the exact same set of tracks.
20:44He may have lost the arthaplora, but Nigel is about to find something just as exciting.
20:51A lake swarming with giant dragonflies.
20:59There's one stop there, there's one flying backwards.
21:02And the speed they're moving, hawker dragonflies in modern times, they can go at 30 miles an hour.
21:07These big ones, who knows what speed they're going to.
21:10And what they're doing is they're looking for mates.
21:12And if they find a female, they grab hold with claspers at the front, and then they start mating with
21:17the female.
21:18But of course they can't identify what sex it is until they get really close.
21:29And these are two males having a dogfight, and look at them. Look at that. They are so aerobatic.
21:38Whoa, he's wizzing right close.
21:43They can stop, they can spin around on a sex piece.
21:57Low over the water there, coming straight towards me.
22:01Hang on.
22:05You can feel the breeze from their wings on my face there.
22:08This is incredible.
22:17This is great. Watching it in the 21st century is fun enough, but to see dragonflies with a three-foot
22:23wingspan having a dogfight.
22:26This is tremendous stuff.
22:33And one's broken off, he's left. The other one, he's patrolling, looking for food now.
22:41The dragonfly settles. Time to get hunting.
22:46Steeping low, moving slow. We've got superb eyesight.
22:5050% of a dragonfly's head is eye.
23:00Ah!
23:03Shit!
23:05Got me, shit!
23:11You all right?
23:13I think it's... something bit me under the water. Look at that.
23:19It's quite a big bite. There must be a big amphibian in there, a predatory fish or something.
23:24And that... that'll be fine. Animal bites for us wildlife blokes.
23:29Just a badge of courage.
23:31Hmm.
23:37Just seeing the dragonfly go up into the canopy.
23:40It's gonna be dark before we know it.
23:42Let's go. We need to find some dry ground and set up camp.
23:52Okay, this is about... the driest we'll get.
23:57Everywhere's soggy here. We're looking for a campsite.
23:59This is slightly above the rest of the swamp.
24:03Got to be careful. The guys, they want to make a fire.
24:05But 20% oxygen in the 21st century, 35% in carboniferous times.
24:10Even this soggy stuff could go up.
24:12So we've got to be really careful around the campsite.
24:22The film crew sets up camp.
24:25The big question is, what might come out in the night?
24:30Don't walk around here without boots on. That's the key to it.
24:33If you have to go for a Jimmy Riddle in the night, use the torch,
24:36because there could be all sorts of stuff.
24:38You know, poisonous scorpions and everything, so...
24:42Bill, what are you doing?
24:42Putting up my mosquito now.
24:44You don't need that.
24:45The mosquitoes haven't evolved yet.
24:47They suck the blood of dinosaurs,
24:49and they won't be around for another 75 million years or so.
24:59The weather turns nasty.
25:03Come on, guys, please.
25:07Right, let's get under.
25:13Sleep well, guys. Sleep well.
25:16But Nigel and his crew will have more to deal with than a storm
25:20before the night is through.
25:28At Prehistoric Park, headkeeper Bob's trying to solve the problem
25:32of the troublesome titanosaurs by giving them rocks to eat.
25:36All right, here you go.
25:38Amazingly, Bob's pebble-planned diet is proving popular.
25:43What's all the fuss about, eh?
25:45Perhaps now they'll stay where they're supposed to.
25:51On the other side of the park,
25:53head vet Suzanne is visiting the observation pens
25:56to see how Terence, the injured T-Rex, is getting on.
26:04Hey, come over here.
26:06Hey, boy.
26:09He looks terrible.
26:10He's really lethargic.
26:12Ah, and look at his face.
26:13That wound, it's opened up.
26:14It's all red and inflamed.
26:15It looks horrible.
26:16I think it's been septic.
26:19Worst-case scenario is he gets septicemia,
26:21which is a disaster, obviously.
26:23We need to give him some antibiotics.
26:25We need to get that sorted out.
26:27It's really serious.
26:31Tests confirm that Terence does have septicemia.
26:36Suzanne decides to take drastic action.
26:38There's blood there.
26:44It's really risky giving him antibiotics because we've got no idea how that's going to act on his system.
26:48But we have to do it, otherwise he's going to die.
27:00Back in the swamps of prehistoric Scotland, the rain has finally stopped.
27:06But there's something more sinister stirring.
27:11Creatures often become active after rains.
27:13And there's something over there.
27:16There's something I want to show you.
27:17It is one of nature's showstoppers.
27:21Experienced bug hunters never go anywhere without a handy ultraviolet light.
27:27And a monster I'm going to show you fluoresces with this.
27:32A scorpion, that's nearly a metre long.
27:35Much bigger than any of the modern scorpions.
27:38It's got a protein in its cuticle in the exoskeleton.
27:41And that fluoresces in ultraviolet light.
27:43Nobody knows why that happens.
27:46But that is gorgeous and what a specimen.
27:49But my camera works shaky and rubbish.
27:52So even though he won't like it, I've got to wake up the cameraman.
28:00Crew member Bill's about to get his own wake-up call.
28:05Oops, he's on the move.
28:06Bill wouldn't like this if he was awake, but I'm not going to wake him up.
28:10The scorpion won't sting unless it's provoked.
28:14And he's moving slowly.
28:17It's getting really close.
28:19So scorpions have got these unique sense organs underneath their bodies called pectines.
28:23Amazing vibration detectors.
28:27And he stopped there.
28:29Bill gave a twitch.
28:30And that's why he's coiled in an attack position.
28:35And I've got to get him.
28:38Just grab him.
28:42Got you.
28:43Ah!
28:44Ah!
28:44Never get used to that.
28:46Got the pincers.
28:47Always forget those pincers.
28:49Sorry, mate.
28:50You've had a scorpion on you.
28:52Three for a metre-long scorpion.
28:56I'll look for him in the morning.
29:02Sorry about that, guys.
29:04Oh!
29:15Next morning, with no change in the T-Rex's condition, Suzanne goes to see how the sabre-tooths are getting
29:21on with their new improved enclosure.
29:29It's amazing what a difference the climbing frames have made, especially for her.
29:32She is such a happy cat.
29:34Look at her now.
29:35She's rubbing.
29:36She's affectionate.
29:37She's rolling on the grass.
29:38She's lying there.
29:39She just looks like a happy pussycat.
29:41She looks really, really good.
29:44And he's still pacing up and down the fence and trying to get her attention.
29:48And she's no longer ignoring him, which is good.
29:51I think, hopefully, she's actually not going to be aggressive and she might even accept him.
29:56Now, Suzanne has to decide if it's safe to put the two animals in together to breed.
30:02If she gets it wrong, there could be a lethal fight.
30:12It's a new day in the swamps of prehistoric Scotland.
30:15And Nigel's determined to catch himself a dragonfly.
30:21Got to be quick.
30:22I'm going to move him quick because he's shivering these wings.
30:25And that means they're warming up.
30:27Oh, it's a fight!
30:28Ah!
30:32He's just too fast.
30:34And this thing is so big and unwieldy.
30:36I've got another idea.
30:42This is my secret weapon.
30:45It works with modern fast-flying dragonflies.
30:48It's a water pistol.
30:50What I'm going to do is I'm going to put detergent in here, fill this with water.
30:54As they go by, like that, shoot them down in mid-air.
30:58They fall into the water.
30:59Because of the detergent, the surface tension on the lake is broken.
31:03They go under the water, get a bit waterlogged, and that should give me time to catch it with the
31:07net.
31:29It's harder than I thought, too. These things are so fast.
31:43Stay there.
31:49Ah!
31:54Take something.
31:55This is our best chance.
31:58Yeah.
32:06Yes!
32:07Quick!
32:09I'm going to get in the net.
32:16Hey!
32:18Got you!
32:24I'm going to get in the net.
32:25At last.
32:28Take the treasure for me, mate.
32:29Thank you, thank you, thank you, thank you.
32:34We've had Marvin in again.
32:48Ah!
32:49This is the mystery penit.
32:52Wow!
32:53And I think I know what it is.
32:55This is Presaturianus scotticus.
32:57It's a fossil that's only ever been found in Scotland,
33:00a real Scottish speciality.
33:02Wow, those jaws are so powerful.
33:05You can see this was the thing that injured me,
33:08bitten off more than it could chew, didn't you, mate?
33:11A really powerful tail there. Look at that.
33:15What I need to do is get him into the shallows
33:17and have a look at him.
33:19Get him!
33:27I need a tight grip behind the head.
33:29This is slimy and powerful.
33:31Look at these.
33:32Ah!
33:33But these tiny limbs, they're for an animal a quarter of this size,
33:37so it wasn't very good on the land,
33:39and I'm pretty sure this thing lived in the shallows,
33:43and what it did is erupted out like a modern-day plight,
33:46caught big fish and other amphibians.
33:48Oh!
33:49And what this thing is is an ambush predator.
33:52Look at the length of the jaw.
33:54They've got to be careful where I put my fingers.
33:55Length of the jaw means it can open its mouth really wide,
34:00perfect snap-trap. Look at that.
34:01And it waits in ambush when prey comes nearby.
34:04It attacks anything that it can dismember.
34:07Fish, amphibians.
34:09Double rope of fearsome teeth in there.
34:11A crassidurinus scotticus hasn't got a common name,
34:15but I'm gonna call this...
34:18...the swamp monster.
34:22Off you go, boy! Off you go!
34:25Bye-bye.
34:26With no way to transport it safely,
34:29Nigel decides to let his swamp monster go.
34:45Look at that crassidurinus.
34:47You're a swamp monster.
34:48You are a swamp beauty! Look!
34:51Look at those exquisite eyes you are!
34:54Gorgeous!
34:58What a dazzling insect!
35:01And I can't resist this.
35:06Gossamer wings, but there's certainly power behind them.
35:09This would be a perfect fan on a hot summer day.
35:12I can stop that now.
35:14There we go. Don't want him to damage his wings.
35:17And look at the abdomen there.
35:20He's flexing it to show us.
35:22And those strange structures there.
35:24No modern dragonflies have got those.
35:26You can see those in the fossils of this species.
35:28And nobody knows what they're for.
35:29They could be used for courtship.
35:30They could be used for grabbing the female.
35:33Come on, then.
35:33We've got to get you back to Prehistoric Park.
35:46It's a big moment for the sabre-toothed cats.
35:51Suzanne is about to open the gate between the two enclosures.
35:55Will they frolic or fight?
36:00I'm still quite apprehensive about doing this,
36:03introducing them and seeing how that goes.
36:04But we've got the water bowser on standby.
36:06And cats really don't like water.
36:08So if it doesn't go very well,
36:09we're just going to blast them apart.
36:11See how that goes.
36:12I think we should do it.
36:14OK.
36:16You guys on standby?
36:18OK, lift the gate now.
36:34OK.
36:36Oh, she's walking up towards him.
36:52Standby, standby.
36:54OK.
36:55OK.
37:04Okay, I think things are going to be okay, she looks like she's quite comfortable in
37:09there and he's not attacking her certainly, so they've got a long way to go before they
37:13mate successfully, but at least they're not attacking each other.
37:18It's a really good start.
37:28With a dragonfly safely in the bag, Nigel begins his search for the giant scorpion.
37:36Think of scorpions in deserts, but lots of them live in places like this in forests and
37:41things.
37:43And there, you get a search image, I just saw something different under here.
37:50There it is, just as I thought.
37:53You can see the eight legs, scorpions, they're not insects, they're arachnids in the same family
37:58as spiders, ticks and mites.
38:01And it knows I'm here.
38:04Incredible sensory systems.
38:05See those hairs on the body?
38:07Uses those to detect air currents and will be sensing my vibrations.
38:11Look, when I move, it moves towards me.
38:15And pretty small claws, that's what I'm worried about.
38:17Small claws, big sting, that means it probably kills its prey using venom.
38:22Scorpions with big claws, they normally crush their prey.
38:28It's a pretty nasty brew, scorpion venom.
38:32There's toxins in there that can muck around with your nervous system, stop your heart beating,
38:36stop your breathing.
38:40And when it raises that sting, it doesn't half get your heart beating.
38:44What I've got to try to do is grab the telson, that's the big bulb beneath the sting.
38:49And if I can get that, I'll be safe.
38:56What I've got to do is try to draw his attention.
39:00There we are.
39:01Come on.
39:02Come on.
39:03He's responding to the vibrations on the stick.
39:06Come on.
39:08This is all or nothing.
39:13This is a strong and powerful creepy crawly.
39:17But this is tiny in comparison to the ancestors of the scorpions.
39:21They were euryptorids.
39:22They came out of the sea.
39:23They got the basic body plan of this.
39:25But they could have been six feet long and weigh as much as I do.
39:29But what I've got to do is somehow get him into a box and take him back to prehistoric park.
39:36But to get a scorpion into a box, you have to let it go.
39:39Here you go.
39:40It's a dangerous moment.
39:43Ah!
39:44Oh, God.
39:50Scorpion venom can take several hours to have an effect.
39:54It may turn out to be toxic or even fatal to humans.
39:58Well, probably not my whole arm.
40:00I'll put a plant on it.
40:01But that's not all.
40:04A couple of miles away, there's trouble brewing that could jeopardize the lives of the entire crew.
40:13At the insect house, Bob has worked out the new threat they're facing for himself.
40:18To keep the prehistoric insects happy, he's recreated the atmosphere found 300 million years ago.
40:27But there's a dangerous side effect.
40:29The high oxygen levels mean things burn much faster.
40:37The lightning storm the night before has started a forest fire.
40:44Look at this.
40:46It's so easy for fire to get a hold.
40:48In carboniferous times, there's so much oxygen in the atmosphere.
40:51This is going to go through the forest at a fair old lick, right towards the Jeep.
40:56What we've got to do is get the animals, get the Land Rovers started and get back to prehistoric park.
41:03Hey, guys!
41:05We've got to move out of here!
41:17Look at all the heat.
41:19The Land Rover's just over there.
41:21The flames rolled around.
41:22Oh, my God.
41:23Look.
41:25It's laying through the fire.
41:28He's got the right idea, but we've got to go towards the heat.
41:37Nigel stumbles, but this is no ordinary fallen log.
41:44Nigel has stumbled across another arthropleura, but it couldn't have happened at a worse time.
41:51Arthur Pleur is burying in the leaf litter.
41:53Must have felt the heat.
41:55But it's got no chance.
41:57It's going to be burnt alive.
42:00Unless Nigel can save it.
42:04I'll be back!
42:18God, this is such a powerful beast.
42:22And even when you get close to it, I'm not sure whether it's a centipede or a millipede.
42:27Look at those mandibles!
42:28Hey!
42:29Jim, quick, quick, quick, quick, Jim!
42:38Move, move, come on.
42:40We'll be watching this place. It's like a tinderbox, quick.
42:42Yes, mate.
42:44Come on, quick. We've got to get out of here.
42:48There's a snail burning insects.
42:50Oh, it's getting so close.
42:53Come on, hurry up.
42:54We don't get much fun.
42:55We'll get this thing moving.
43:02With the engine out of action,
43:03Nigel needs to find a way to get them
43:05and the jeep through the time portal
43:07and back to the park before it's too late.
43:53When you've got a park full of dinosaurs, you'll never need it.
43:59Come on.
44:00Come on, this way, Andy.
44:01And Bob knows just how to say thank you.
44:05Hey, Arnold.
44:10That's it.
44:12Good girl.
44:13Good girl. Well done.
44:17Don't do anything for a treat.
44:32Everyone's back safely, but Nigel's still got something on his mind.
44:38I think he's going to be fine.
44:40It probably would have had an effect if it was going to by now if he'd be really sick.
44:43And the scorpion venom is designed to kill insects and luckily he's a mammal.
44:47So, Nigel, I think you need a good night's sleep. I think you'll be fine.
44:49Thanks, Susie.
45:00At the insect house, Bob is checking up on the new arrivals.
45:04Let's see.
45:18Where is he?
45:20He's around here somewhere.
45:25Yeah, he is.
45:30I'm not actually too woody because, as it turns out, the Arthur Fleur is actually a vegetarian.
45:35You know what the funny thing is?
45:37I'm really rather fond of him.
45:39I think it's because he's big.
45:40He's not like an iggly wiggly little spider or something that creeps up behind you.
45:43He's like a proper animal.
45:56Something's up at the vet surgery.
46:02Dan, I thought you had bad news.
46:03Terence is okay by looking at him.
46:05He's fine.
46:06He's doing really well.
46:07The good news is he responded to the antibiotics.
46:09He's fine.
46:10The bad news is I didn't restrain him because I didn't think he'd come round so quickly.
46:13He's on the loose.
46:14He's bashing around.
46:15He's destroying my surgery.
46:17I don't know how we're going to get him out.
46:20Rob.
46:22Hello, mate.
46:22Nigel here.
46:24Can you get over here?
46:25What a real surprise for you.
46:32A few hours later and Terence the T-Rex is safely back in his enclosure.
46:38Thanks to a tough immune system and a bit of modern medicine, he should make a full recovery.
46:46Leaving Suzanne the minor job of tidying up the surgery.
46:55Next time, Nigel goes back 75 million years to catch the biggest crocodile of all time.
47:06Suzanne finds out if the sabre-tooths will finally have guns.
47:12And the titanosaurs throw some serious melee.
47:19But for now, at least, all is calm at Prehistoric Park.
47:24I'm gonna.
47:38Oh.
47:39Oh.
47:43Oh.
47:44Oh.
