00:10One hundred and twenty-five million years ago, winter rages across the north.
00:26Entire species have been pushed to the brink.
00:40Even the largest dinosaurs are unable to endure this cold.
00:52Like these sauropods migrating south.
01:04Wreda came early this year and caught them off guard.
01:19With hundreds of kilometers ahead of them, this time it will be an especially harsh journey.
01:33But the bitter cold is not the only danger in this frozen land.
01:41There is a much greater threat here in these woods.
02:06Euteranus, the Snow King.
02:13An early relative of T-Rex.
02:20With a thick, insulating coat of feathers, he's perfectly adapted for life in a world this cold.
02:35But his feathers also serve a more sinister purpose.
02:46An early relative of T-Rex.
02:47Camouflage.
02:49The ultimate weapon for an ambush hunter.
02:54An early relative of T-Rex.
02:54The S-Rex.
02:55The S-Rex.
03:05The S-Rex.
03:16With silent precision, he picks out the smallest member of the herd.
03:52In a savage, ever-changing world, some will rise, and some will fall.
04:06But through it all, the dinosaurs will expand their empire and advance relentlessly to seize Earth's final frontiers.
04:44In a savage, ever-changing world, some will rise, and some will rise.
05:00In a savage, ever-changing world, some will rise.
05:27To be continued...
05:47It's a new age for life on Earth.
05:52An age of extremes.
05:56New worlds are forming that will give rise to the most famous dinosaurs of all time.
06:10The North is still gripped by cold, but not for much longer.
06:23Earth's most violent forces are staring once again.
06:33Volcanoes see the fume, warming the planet.
06:52But some will pay a price for this warmer world.
06:57The North is still a new world.
06:57The North is still a new world.
07:06The North is still a new world.
07:26The North is still a new world.
07:30The North is gathering a new world.
07:42It's still a new world.
07:44Erived to your territory.
07:46Ten years of Tolda but not csak at all
08:10This thawing of the north is expanding the dinosaur's empire even further, and in surprising
08:22new ways.
08:31In this fresh, fertile landscape, sauropods no longer need to migrate.
08:40But it's also a new world for one of the dinosaur's oldest rivals.
08:47The pterosaurs.
08:52They are now bigger and badder than ever, including Gway Draco, the ghost dragon.
09:13But he's an intruder here, because these trees are the home of Longipteryx, a new kind of
09:29dinosaur, less than 20 centimeters tall, but highly territorial, especially during nesting
09:51season.
09:55They're also equipped to take on the pterosaurs.
10:03Now they, too, can fly.
10:16In a previous era, flying dinosaurs like Ancyonis could only glide.
10:25Now they're able to flap their wings and maneuver with precision to strike at their enemies.
10:43They're fast and fearless.
10:58It only gets worse for the towering pterosaur, because Longipteryx are distant cousins of Eutyrannus,
11:09the snow king.
11:12They're armed with the teeth and claws of their clan.
11:28After ruling the skies since the Triassic, pterosaurs are now being matched by the dinosaurs.
11:46But as the dinosaurs fight to expand their empire into the air, an even greater revolution lies ahead.
12:06Not in the mountains, or the skies, or the oceans, the biggest twist in Earth's tale is unfolding quietly, almost
12:22in secret.
12:27That's how it turns out.
12:28Seven million years later, this new force is slowly rewriting the dinosaur story.
12:50This is one of the first flowers that we have on the planet Eutyrannus
12:53this forest has ever seen just one in a vast and diverse new generation of plants
13:07and they will become a phenomenon with the help of a close ally
13:23beetles they carry pollen from one flower to the next
13:35nature's most reliable delivery service
13:44helping these new plants spread far and wide across the globe
13:56transforming the dinosaurs empire
14:11but this new generation of plants has a dark side
14:25while they need to attract pollinators many are also evolved to repel herbivores
14:37with spines thorns and poisons
14:50nature's defensive weapons
14:58this green revolution changes everything for the plant-eating dinosaurs
15:08including the great stegosaurs
15:21they're heard animals by nature
15:25but this young stegosaur barely two years old is all alone
15:39the last of her herd
15:54to eat these tougher new plants requires mouthful and chew food
16:00in a way her primitive jaw cannot
16:12she's starving
16:27to eat these once great herbivores are unable to adapt to this new world
16:34to adapt to this new world
16:36to adapt to this new world
16:36to adapt to this new world
16:41to adapt to this new world
16:41it's one reason why their 50 million year existence
16:45will come to an end
16:49extinction
16:59but in the wake of the stegosaur's demise
17:03a new era will emerge
17:12over the next 15 million years
17:15these new plants evolve
17:18and diversify
17:21spreading across the planet
17:23and ever further into the dinosaur's empire
17:36the green revolution
17:38the green revolution
17:39now covers the globe
17:42and not just the land
17:45but the water as well
17:52even providing cover
17:56and food
17:59for underwater explorers
18:04it's like ankylosaur's
18:08like ankylosaur's
18:27This bathing beauty is a different kind of dinosaur.
18:39He's a plant eater.
18:40Like the stegosaurs, but a fancier one, much fancier.
18:55Because unlike the stegosaurs, his advanced jaw can crush food in a way that makes eating any kind of plant
19:06easy.
19:09It's the perfect adaptation for this diverse new world.
19:22He wants to take full advantage of all this great kingdom has to offer.
19:30And he has a plan.
19:41It's a long trek.
19:46But the journey is worth it.
20:07This is the one place where he can truly be himself.
20:22His passion is singing.
20:33He even has special hollows in his snout that amplify his song.
20:44So it can be heard far and wide.
21:12His passion goes into the air for forever.
21:31A female has answered his call.
21:36It's time to charm her with his deep, sultry humming.
21:49Then, he shows her his stylish armor.
22:04It's all very persuasive.
22:27Their fancy attire does have some drawbacks, mind you.
22:35On the whole, though, heavy armor and an improved jaw are setting them up for success.
22:50But what no dinosaur could possibly know is that their empire has been gradually shrinking.
23:04Hidden below the waves, this world, once ruled by dinosaurs, is now completely out of their reach.
23:25And there's a reason, at the very bottom of the ocean, a slow, imperceptible shift reshaping the planet.
23:51The seabed is fracturing from an endless progression of eruptions.
24:25Earth's tectonic plates are shifting.
24:30Breaking apart the ocean floor, lifting it higher over millions of years.
24:42The water above has nowhere else to go but up.
24:49By the middle of the Cretaceous sea levels reach their highest point in history.
24:57Over 200 meters higher than they are today.
25:18The rising oceans repaint the map of the world, erasing entire land masses.
25:30The continent of Europe is reduced to a giant archipelago that includes the Isle of Herzig.
25:45A world where isolation and evolution have created a kind of neverland for the dinosaurs.
25:54A world where normal rules don't apply.
26:04This is the home of Magyarosaurus, a sauropod.
26:15And, like other sauropods, he uses his long neck to reach the highest vegetation.
26:33The thing is, this vegetation is only two meters tall.
26:41Which makes Magyarosaurus about the size of a pony.
27:03On Hatzegg, where there's limited space and food, sometimes smaller is better.
27:27But unlike Magyarosaurus, for predators, digger is still better.
27:49As tall as a giraffe, one of the largest pterosaurs to ever live.
28:00As tall as a giraffe, one of the largest pterosaurs to ever live.
28:10She's flown to this island to feed on dinosaurs.
28:16She's flown to this island to feed on dinosaurs.
28:25The youngest member of the herd gets separated.
28:36But it won't be an easy catch.
28:41Unlike his giant cousins, he's light on his feet.
29:12But being this small, he can't see the other side.
29:15They're so jealous.
29:24They found a safe hiding spot.
29:27Perfect for their size.
29:29eyes.
30:10I don't know.
30:38I don't know.
31:12The tiny dinosaurs trapped on an island has nowhere else to go.
31:31But in a world so divided by the ocean, evolution takes different turns in different places.
31:4996 million years ago, sea levels are close to the highest they've ever been.
32:06Creating a water world that no dinosaur has dared to enter.
32:19But that's about to change.
32:35Lurking in this mangrove swamp is a carnivore that has specially evolved to take on the final frontier.
32:56A dinosaur pioneer.
33:12Spinosaurus.
33:19The largest predator to ever walk the earth.
33:29At 15 meters long, she's bigger than a school bus.
33:41The forest provides plenty of prey.
33:48But another reason she's gotten this big is because of where she goes to escape the gloom
33:57of the swamp.
34:14Here, the high sea levels have turned the oceans into a new hunting ground for the dinosaurs.
34:23Where bigger is definitely better.
34:54Spinosaurus is adapted to a planet that is now mostly ocean, and in this age, some of
35:03the largest prey is here in the water.
35:23Sharks.
35:29In a flat-out chase between a shark and a giant dog-paddling dinosaur, the shark, the
35:37shark, will always win.
35:42But there's more to Spinosaurus than meets the eye.
35:53Dinosaurs aren't just becoming bigger.
35:57Some are cunning, too.
36:01She's going to make the sharks come to her.
36:16Her snout is wired with sensors that can detect the slightest movement.
36:25Now, all she needs to do is keep completely still.
36:48The best hunters are the patient ones, and her patience is starting to pay off.
37:06The blood in the water is drawing the sharks closer.
37:53She doesn't move.
38:00She knows how this game is played.
38:23Brains and brawn.
38:27A killer combination.
38:30That is finally letting the dinosaurs get a foothold in the ocean.
38:45Their reach is now global, and extends to the very ends of the Earth, to what will one
38:59day be Antarctica.
39:12While Spinosaurus is stalking the shallow seas and the tropics, the world's southernmost
39:20landmass is not the frozen wilderness we know today.
39:26It's a green, flourishing Eden, where even in the dark, evolution is lighting the way.
39:51And thriving in the darkness are the dinosaurs.
40:09By this stage in the late Cretaceous, their empire is so vast that they now dominate every
40:18continent on Earth.
40:28And yet, while their reign is global, and their rule almost unchallenged, their story will take
40:45a dark turn.
41:07It's like a dark turn.
41:15And now to the very上 of the years, please?-
