"There is something missing from our world." "The amazing animals that time has left behind." "But what if we could bring them back?" "What if extinction didn 't have to be for ever?" "We 're going back in time on a safari with a difference as wildlife adventurer Nigel Marven plunges into prehistory to rescue creatures on the brink of extinction." "His plan is to bring them back to the safety of the present and give them a second chance." "This time Nigel travels to the perilous forests of prehistoric China to track down one of the most bizarre dinosaurs ever." "And there are some big surprises on the way." "Welcome to the ultimate wildlife sanctuary." "Welcome to Prehistoric Park." "Nigel's dream of creating a park full of prehistoric creatures has become a reality." "There are now over two dozen prehistoric animals ranging from the quiet ostrich-like Ornithomimus to Theo the Triceratops," "prone to tantrums." "Pride of the Park are the two Tyrannosaurus Rex, brother and sister, Terence and Matilda." "They seem to be settling in well..." "and growing up fast!" "(Roars)" "But, in the intense summer heat," "Martha the Mammoth is finding the adjustment to 2 1st-century living a little, well, hairy." "Hello, Martha!" "(Groans)" "Such a joy." "Martha's really integrating with the African elephant herd, but we had to put Prehistoric Park where it was warm for the reptiles and dinosaurs, and that's not ideal for an ice Age mammal." "They're close cousins, but they are as different as chalk and cheese." "The African elephants are constantly flapping their ears and those are perfect for losing heat." "They move them, create air currents, and they dissipate heat in that way." "But Martha's got tiny ears." "She's designed for conserving heat - thick blubber, a massive, shaggy coat." "So you're really struggling, Martha, aren't you?" "Luckily, Nigel has a cunning plan to cool Martha down, but it will have to wait because he's getting ready for his next prehistoric rescue mission." "For bird lover Nigel, it's going to be a very special adventure." "He 's going to search for an amazing new fossil discovery - a dinosaur with four wings." "I 've been sent these pictures of a revolutionary kind of fossil." "It's a tiny dinosaur called Microraptor, but if you look closely there, there's impressions in the rock of feathers." "So evidence is building that birds are the direct descendants of dinosaurs." " I want to go back and..." " (Parrot squawks) find your ancestors, find the dinosaurs that led to birds." "It won't be easy." "He'll have to go back 125 million years to find one." "Microraptor is only known in one remote corner of prehistoric China, in a place of mysterious dinosaurs and deadly volcanoes." "Nigel will need all the help he can get from his team to track down the four-winged dinosaur and rescue it from this forbidding world." "It's a world more hostile than Nigel had imagined." "(H issing)" "We've got to get away from here quickly." "U p onto the high ground." "There's a forest there." "That's good for Microraptors." "Let's get the equipment and go." "This is a really worrying situation." "The perils of a volcanic area aren't just explosions and molten lava." "An active volcano like that is seeping gas." "Carbon dioxide is invisible, you can't smell it." "It's heavier than air, so it gathers in an invisible carpet that is deadly." "So the best thing is for us to get up to higher ground." "(Rumbling)" "Everyone OK?" "That was just a tremor." "We've really got to keep an eye on that volcano." "Let's go." "We can't hang around here." "As fast as you can." "Let's move." "The team head away from the volcano, up into the apparent safety of the forest." "But is it a case of out of the frying pan, into the fire?" "Nigel's come here to find the Microraptor, but he has no idea what other creatures are lurking in the forest." "(Animal screeches)" "A freshwater lake seems the safest place to make camp." "And it's not long before they get their first sighting of prehistoric life." "(Y ells) Quickly!" "Come over here!" "Have a look at these!" "Come on, come on!" "Up there." "They are magnificent." "These certainly aren't the four-winged Microraptors." "They're not dinosaurs at all." "They're a type of flying reptile called Pterosaurs." "An exclusive group of backboned animals." "Only three groups of them have the ability to do powered flight - these, the birds and the bats." "Bats haven't evolved yet." "These Pterosaurs, they've been masters of the air for 1 00 million years." "There's a group fishing out there, skimming low, lower jaws in the water." "When they feel something moving, the jaws close like a snap trap." "Wow!" "You can see how they fly." "A membrane goes between their limbs and their body." "That's what gives them the ability to do these amazing aerobatics." "He's swooping down to the water there." "(Pterosaur screeches)" "Oh!" "Thank you!" "But as an excited Nigel returns to camp, he's in for a nasty shock." "Tent gone over there." "Oh..." "Everything has been pulled out of the tents." "Look at this." "Sleeping bags destroyed, most of the tents are wrecked." "The creatures that came in here, that's what they were looking for - they've gone right into the food bag." "There's hardly anything left, just a few slivers of meat." "So we know that the creatures that raided the campsite eat meat." "I've looked around for tracks." "I've no idea what they are." " Has anyone else got any food?" " (Man) Yeah." "I had this bag with me, so they didn't get it." "I've got some food in here, some bread." "And dried meat, I think." "Hardly enough to keep the team going for long." "The expedition must be cut short." "There are worrying signs that Nigel may have bitten off more than he can chew." "Oh, no..." "Nigel's mission to save the Microraptor has not started well." "His camp has been wrecked and most of the food stolen - by what, no one knows." "Nigel is still upbeat." "For a zoologist, it doesn't get much better." "I'm in pursuit of a creature that no one has ever set eyes on before." "We've got an idea of what a Microraptor looks like." "One of the smallest dinosaur fossils ever found." "Four wings, feathers." " What colour was it?" "How did it behave?" " (Rustling)" " (Yells) There!" " (Animal shrieks)" " Over there." "Listen!" "Hear that?" " (Rustling)" "(Man) It's over there!" "In the ferns there, look!" "Stuff moving all around us." "(Man) Guys... (Animals shriek)" "(Nigel) Hey!" "Wait!" "Come this way." "The rest of you, keep close together." "And let's keep moving uphill." "Whatever they were, they've gone now." " Come on." "There we go." " (Groans)" "Back at the Park, Martha the Mammoth is still feeling the heat, so it's time for the staff to carry out Nigel's cunning plan to cool her down." "Good girl, Martha." "You're OK." "Good girl." "That's great." "Stop her there." "Excellent." "Good girl, Martha!" "Well done." "Good girl." "Just stay there." "OK." "Can I get those?" "Great, thanks." "(Martha growls)" "Martha's an ice Age creature, so everything about her has evolved for really cold temperatures." "I think she might just be overheating." "Nigel had the idea to give her a haircut, which is a really good idea." "Hope she'll feel much better." "You're OK, sweetie." "You're going to feel much happier." "Not every girl gets a summer makeover." " (Sneezes)" " Martha!" "Thanks very much!" "Oh!" "Great." "It's not that bad." "Meanwhile in prehistoric China," "Nigel and his team are on the trail of the Microraptor." "(Animal shrieks)" "But something is on their trail, too." "(Man yells) Over there!" "Again, it's gone." "Scurrying down there." "Let's keep going." "I don't like this." "Back in the 21 st century," "I just need to get a glimpse of an animal and I've got some idea of what it is, but here at this time in prehistory," "there's so many strange and bizarre creatures." "I've no idea what's following us." "That really is disconcerting." "But surely not everything in this forest is dangerous?" "(Animal chirps)" "There!" "(Chirps)" "(Whispers) I wonder if this is our tent wrecker." "I'll try to get a bit closer." "(Chirps)" " (Hisses)" " Hey!" "(Screeches)" "Whoa!" "He smacked right into the lens!" "Some dinosaur spit there." "And there's..." "Oh!" "...a smear of dinosaur snot." "I think that was a mock charge, though." "That was like a warning shot." "He wasn't attacking us." "I don't think this is a predator." "This isn't the tent wrecker." "Look at him." "He's a vegetarian, like me." "See him nibbling away at the ferns." "I'm certain this isn't the creature that ripped through our tents." "Not Microraptor, either." "Those big buck teeth, Microraptor doesn't have that." "This creature does have feathers, though, and they are on the front limbs." "I'd like to see what he does with those." "Come on, then." "Let's put you through your paces." "Show us what you're made of." "Hey!" "You are fast!" "(Nigel laughs)" "Brave little beggar." "That really ruffled his feathers!" "That's all he can do with them." "When he jumped, he didn't use them to stay airborne." "Those feathers aren't for flight." "Are they?" "It's an exquisite reptile." " This is a rare find..." " (Man yells) Aagh!" "Aagh!" "Aagh!" " (Screeching)" " Help me!" "(Shrieks)" "They're after the food!" "Take your bag off!" "They're away." "We've lost the food." " How are you?" " I'm OK." "I think." "It's not as bad as I thought." "They just strafed you with their claws." "If they'd bitten, it would be much worse." "I'm sure they wrecked the campsite." "Now we have no food, they won't follow us." "You could have a little scar there." "That's a badge of courage for a zoologist." "But this forest has a few surprises in store yet." "Back at the Park, head keeper Bob checks to see if the Ornithomimus enjoy their new home." "I built this hide to keep an eye on them, but there's no need." "They're happy here." "Look at them!" "They're dabbling about like ducks." "We've given them a real home from home." "Oh, they love it." "Well, except for that one." "I'm very worried about it." "It's gone completely bonkers." "If it's not lying sulking in the shade, it's creeping round the undergrowth, keeping well out of the way of the others." "While Bob ponders over that mystery in prehistoric China, Nigel's stumped." "There's still no sign of the Microraptor." "The mission's falling apart." "We've got to find the Microraptors quickly." "And I'm not even too sure where to look." "They've got features of dinosaurs." "Could they be scurrying on the ground?" "Features of birds." "Could they be up there in the tree canopy?" "(Animal squawks)" "Look up there!" "Right in the treetops." "That's a Microraptor!" "When it glided, I saw the four wings." "This is definitely a Microraptor." "And it's off!" "We've got to keep up now." "It's hard." "He's going from tree to tree." "Just jumping across that gap there." "Where's it gone?" "I think there's more!" "There's another one there." "So aerobatic!" "And this is a group." "There's four, three or four of them, moving that way." "They are fantastic!" "And they're all calling together." "They're all moving in the same direction." "I wonder where they're going." "(Animal groans)" "I've seen fossils of these." "These are Titanosaurs." "They're in the Sauropod dinosaur group, some of the biggest to ever live." "Harmless vegetarians, unless they tread on you!" "But you wouldn't normally find them in dense forests." "I don't know what they're doing here." "And they are magnificent!" "(Rumbling)" "Listen to them crashing through the vegetation!" "Titanosaurs can weigh over 20 tonnes." "It takes a lot to stop them." "Look at the mess!" "They turn over the earth and the footprint is full of creatures - look at this." "Loads of earthworms there, a big beetle grub and there, a primitive cricket." "I wonder if all this food explains what's going on." "Look up there!" "When dinosaurs move through the forest, they turn over the soil and then the Microraptors feast on the insects," "like birds in a ploughed field." "It's an irony." "You wait all day for one Microraptor, now I'm watching a dozen!" "Breathtaking stuff." "You never see them flap their wings." "This isn't powered flight, but they are superb gliders." "It's a great way to keep above ground predators and to cover vast areas looking for food." "With the Microraptors busy feeding, this could be the chance Nigel's looking for." "(Whispers) Microraptors don't disappoint." "They're so strange and peculiar, a species that will soon become extinct unless we get some back to the Park." "I can't muck around anymore." "I'll see how easy they are to catch." "(Squawks)" "OK, so they're faster than me!" "At least we learnt something." "They use their claws like grappling irons." "They can shin up trees like squirrels, but can't take off like birds." "They need a launch platform." "I've an idea." "All we need is a bigger area than this." "The Microraptors are wilier than he first thought." "But with his knowledge of bird behaviour," "Nigel's confident he can outwit his new feathered friends." "My idea with this trap is to exploit their aerial limitations." "We've seen them in these trees." "Hopefully we can lure them to glide down and then, because they can't do powered flight, they can't take off from standing, these walls will keep them in." "How are we going to attract them down?" "I've dug some soil, plenty of earthworms." "And if I break some rotting wood like this - this is what the Titanosaurs do - and, hopefully, there's some insects inside." "And there, there's some grubs." "There's one of those crickets again." "With a whole variety of moving insects, the trap is now set." "Let's hope the Microraptors understand the plan." "(Screeches)" "Just need one brave one." "This will work because the others will follow." "Come on, this time." "They're all interested in the food, but suspicious of the trap." "There's another just about to come now." "So close." "Surely Nigel must net something soon." "Sooner than he thinks, in fact." "What are they doing here?" "It's a couple of those buck-toothed things, coming straight for us." "(Chirping)" "With the trap ruined," "Microraptors discover there is such a thing as a free lunch." "I don't believe it." "(Squawking)" "Damn!" "This is so disheartening." "Microraptors in the tree, it's like they're taunting us." "Trap's been knocked down, in an hour or so it's going to be dark." "I think we've got to go back to the Park and work out a new strategy." "This is just hopeless." "Who'd have thought that a tiny dinosaur could cause such a big headache?" "Back at the Park, the heat wave is getting worse." "Now Nigel's back, he wants to know how the creatures are holding up in the extreme weather." "Some of the animals are beginning to get a bit bad-tempered." "(Roars)" "And as for the Ornithomimus, she's still just acting plain daft." "T o be honest, I'm very worried about one of the Ornithomimus." "They seem to be very sociable creatures, but one has cut herself off, she's lying in the shade, has lost the plot." "I know what's going on." "Ornithomimus means "bird-like"." "I've seen it in birds before." "She's getting broody." "We need an ultrasound scan." " Ultrasound?" " If there's eggs, we can see them." " Our first pregnant dinosaur!" " That'd be something!" "Nigel is eager to get back to his latest mission." "He's confident he can catch the Microraptor with the help of a new toy." "I wasn't properly prepared last time." "I was disappointed." "I've done some research and this is the thing to help me." "A scientist in Florida studies birds of prey and he uses this." "It's a net gun." "Microraptor is very delicate." "I don't want to damage it, so this is the perfect device." "Watch." " What the..." "Nigel!" " (Nigel laughs)" "(Nigel) I'm sorry, Bob!" "It's back to prehistoric China and this time Nigel means business." "But this is a dangerous place and he'll have to watch out for ever-increasing levels of volcanic activity." "As we found when we came back before, these volcanic landscapes can be perilous." "This time I'm much better prepared." "I've got a carbon dioxide monitor." "If levels of the gas get toxic, this will detect them." "We've all got a gas mask in our backpacks in case there's a cloud of volcanic gas." "You don't want to breathe that in." "That will lacerate your lungs." "Hopefully, we've got everything covered." "It's not long before Nigel meets an old acquaintance." "(Whispers) Quick." "Have a look at this." "It's that peculiar creature that wrecked the Microraptor trap." "I think he's got a girlfriend." "I'll try to get closer." "I researched these at Prehistoric Park." "Like Microraptors, they're another strange creature only found in this place and time." "They call it lncisivosaurus because of those protruding front teeth, incisor-like teeth at the front." "It looks to me like they're halfway between dinosaurs and birds." "That would make sense because the male is displaying to a female" "like some modern birds do to their mates." "He's got those beautiful colours to flaunt them to females." "And when he attacked us, raised his crest, ruffled his feathers, he thought we were after his female." "Remember when he wrecked the trap?" "He was chasing a competitor." "Maybe he thought that male was going to take his mate away." "So it's likely the first function of feathers was to keep dinosaurs warm, then some, like lncisivosaurus, used them for display." "Flight evolved much later, a sort of accidental benefit for some of the animals that had them." "I could watch you for hours, but we've got to go." "Let's go and catch the Microraptor." "At the Park, it's time for vet Suzanne to give the Ornithomimus her ultrasound scan, to determine whether she really is the Park's first expectant mum." "OK, she looks fairly calm." "Can I get that probe?" "OK, get some gel on there." "How's her head?" "Is she OK?" "Great." "OK." "Let's just put this probe on and see how she goes." " Good girl..." " (Shrieks)" "Whoa!" "OK, just let her be." "We put a bag on her head, which is what we do with ostriches to calm them." "I think the gel was just a bit cold, it was a bit of a shock." "That's where I'm going to be." "That's it." "OK, I'll just get her used to it." "OK, let's try that again." "Good girl." "That's good." "All right, so there's one oviduct there with an egg." "That's good." "Let's see what else we've got." "Look, it looks like another one." "Another oviduct, another egg." "Let me see it's not the same." "No, it's a different one." "That's great." "She's got two oviducts with two eggs." "Modern birds have one oviduct." "That's an evolutionary thing, to make them lighter so they can fly." "If she lays two eggs a day and does what birds do - lay on consecutive days - we might end up with loads of new dinosaurs at Prehistoric Park." "It's great news." "One problem solved, but as frequently happens at Prehistoric Park, another is about to begin." "Temperatures are still rising on T-Rex Hill." "(Roars)" "Back in prehistoric China, Nigel's hot on the trail of the Microraptors." "This is what we've been searching for." "Like a convoy of trucks has been through." "You don't have to be a master tracker to follow Titanosaurs." "When we find them, we should find the Microraptors." "The problem is the trail heads downhill, towards the volcano and, on the way, some of the forest's less-welcoming residents." "(Whispers) There's some of those creatures that made our life a menace before." "Sleeping, I think." "I researched them." "They named the fossil Mei Long, which means "sleeping dragons"." "What we'll do is skirt round here so we don't wake them up." "There's something not right here, though." "Something not right." "(Nigel claps)" "They're not moving at all, not responding." "(Monitor beeps)" "(Yells) Carbon dioxide!" "Get to higher ground!" "Move!" "Move!" "As things hot up for Nigel in China, back at the Park they've reached boiling point." "(Roars)" "The T-Rex are at each other's throats." "It's up to head keeper Bob to cool them down before it's too late." "(Y ells) Open the gate!" "Come on!" "Quick!" "We haven't got much time!" "Quick as you can, lads." "Right, soon as you're clear, get the gate shut." "That's it, lads!" "Get that water pumping through!" "Come on!" "Up as high as you can." "That's it." "That's the way." "Higher!" "A bit higher." "Hey, lads, come on!" "Come on, quick as you like!" "That's it, that's it!" "That's it, keep the pressure up!" "The drama's over with no major injuries, but Terence and his sister Matilda will be separated for their own good." "They're being moved to holding pens while a dividing wall is built." "Terence doesn 't seem too impressed with his new accommodation." "And Matilda, for once, seems to be in agreement." "Well done, guys." "In prehistoric China, Nigel and his team have safely reached high ground, narrowly avoiding suffocation by the gas cloud." "Cor, that was a close one." "Those poor little Mei Long choked to death." "I think there was a burst of carbon dioxide from the volcano, it seeped through the forest and killed the little dinosaurs in their sleep." "His narrow escape has confirmed his fears about the dangers here." "This really isn't looking good." "Titanosaurs are ploughing through the forest." "The Microraptors will be following them, but they're going straight towards that toxic lake and the volcano." "Following the trail back down seems a big risk for a very small dinosaur, but after all he's been through, Nigel's not giving up now." "Some freshly-turned soil here." "This is a nest." "This explains why the Titanosaurs have come deep into the forest and towards the volcano - eggs here." "The soil's been warmed by the volcanic activity." "That's a perfect incubator for these eggs and reptiles rely on the heat of the sun on the ground to hatch their eggs." "Let's gently take this..." "I've got to be careful I don't turn the egg." "If I twist it, the embryo inside will die." "Reptiles don't turn their eggs like birds do." "And there..." "It's always extraordinary to me that a relatively tiny egg like this the embryo inside will increase in weight by 30,000 times." "This egg will lead to an animal that weighs 30 tonnes." "Let's put it back very carefully." "(Rumbling)" "Another tremor." "That was the strongest yet." "You could feel the ground shake." " Listen." "Can you hear that?" " (Rustling and creaking)" "Coming from over here." "Unmistakable sound of splintering wood." "Titanosaurs on the move." "And, as I thought, there's another egg-laying site." "Microraptors won't be far behind." "Let's move." "Skirt round this way." " (Animals squawk)" " Can you hear them?" "There they are." "This is what we came back for." "There's one in the tree up there." "They're such strange creatures." "Soon to be extinct, probably because they'll be out-competed by birds." "Microraptor's a strange evolutionary experiment - dinosaurs with four feathered wings." "To this population here and to all the animals that live here, there's a threat." "The volcano is very volatile." "We've got to move fast to save these Microraptors." "The moment has come for Nigel to put his plan into action." "And this time he thinks he's got the right equipment to finish the job." "(Squawks)" "Got you!" "Get him in there." "He'll calm down in the dark." "It's not too big." "He won't thrash around." "He'll be fine in there." "What I'm going to do is get some more." "At last Nigel's persistence has paid off." "He just needs a few more and he'll have a breeding colony of Microraptors to take back to the Park." "Y es!" "Got him!" "One more should do it." "Nigel's on a roll." "Surely it can 't last." "Got you!" "(Rumbling)" "(Groaning)" "That was a massive tremor." "Look at the volcano." "In fact, it's not just a tremor this time." "The volcano is erupting." "(Chirping)" "And it's spooking all the animals, even the big ones." "That was a close one!" "The Titanosaur clipped his wing." "It's a minor injury, so I think he's OK." "You're OK, aren't you?" "(Thunderous boom)" "Wow!" "Oh, no!" "There's a huge cloud of volcanic ash." "Volcanic ash is made of tiny sharp crystals." "It can be deadly if breathed in and is best avoided, even by the largest of dinosaurs." "The Titanosaurs are heading straight for it." "Can you take this?" "The ash cloud's coming this way." "The ash is coming!" "Most people would see a volcanic eruption and 300 tonnes of dinosaur stampeding towards them as a problem." "Nigel, however, sees this as an opportunity, if only he can get the time portal up and running quickly enough." "(Coughs)" "(Groans)" "Run!" "(Roaring)" "You got the Microraptor, then?" "You got the Microraptor, then?" "I don't believe it!" "Nigel!" "Hey, now!" "Watch me fence!" "Hey!" "Oh!" "There's another one!" "Look at the size of that, man!" " Nigel?" " How many have come through?" "So far, three." "How many are there?" "Well, that's four." "Oh...nine." "Oh, my word!" "Look at the size of them!" "Nigel, where am I going to put these?" "As Bob is left to round up the Park's surprise guests, vet Suzanne gets to work on the Microraptor's injured wing." "Gosh." "It's amazing how similar the M icroraptor's wing is to a common bird's." "A little fracture of this bone here." "I'll just put a splint on it." "OK, can I have a splint?" "Thanks." "This is how I'd repair a bird's wing." "I'm going to do is stitch it in place, though, just around the actual soft tissue, which will make it much more stable." "That's good." "OK, let's bandage that." "OK." "Hopefully that should keep it still enough and she'll be fine in a few weeks." "With the Microraptor on the mend," "Nigel's keen to see how one of Suzanne's other patients is getting on." "The Ornithomimus, she's been pretty secretive." "She must be laying now." "We haven't seen her for a few days." "And there, look." "We knew it was going to happen from the ultrasound." "Eight eggs, I think." "One, two...one hidden there..." "Eight eggs." "And it's not just thrown about like the Sauropods." "There's a semblance of a nest here." "(Squawks)" "OK." "I'm just looking at your eggs." "OK." "She's so tender with them." "With luck, it won't be long before the Park is home to the first baby dinosaurs for 65 million years." "Two weeks later and the injured Microraptor's wing is healing well." "Hello, you two." "How are you doing?" "Hello." "Snails for you." "Want a peanut?" "There you go." "Must be lovely for you to meet your ancestors, mustn't it?" "That's enough." "You're hungry." "It's been a long, hot fortnight, but everything at Prehistoric Park at last seems to be cooling down." "Martha the Mammoth is comfortable with her new haircut." "The strange behaviour of the Ornithomimus turned out to be pretty normal for an expectant mum." "And, for the time being, the T-Rex are no longer trying to kill each other." "Next time, Nigel's on a mission to rescue the predators of prehistoric South America, including the legendary sabre-toothed cat." "And the Park wakes up to the pitter-patter of tiny three-toed feet." "But now, Bob 's rounded up the Park's latest residents, the Titanosaurs, and he 's confident his newly-built fence will keep them out of trouble." "The Titanosaurs, however, beg to differ."
