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.
01:05Wreda 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.
02:04Euteranus.
02:07The Snow King.
02:13An early relative of T-Rex.
02:19With a thick, insulating coat of feathers, he's perfectly adapted for life in a world this cold.
02:36But his feathers also serve a more sinister purpose.
02:47Camouflage.
02:49The ultimate weapon for an ambush hunter.
02:53The Azeri.
02:53The End
03:16With silent precision,
03:19he picks out the smallest member of the herd.
03:45We have to trap them,
03:52and then go to their теперь.
03:53And 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
04:16To seize Earth's final frontiers
04:31In the глав of the universe
04:35The model of the universe
04:35The world is not the same
04:35If we can find this one
04:39It is the only one
04:40It is the same
04:40The only one
04:42The core of the universe
04:42The core of the universe
04:44The universe
04:45The core of the universe
04:51The core of the universe
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.
06:23Earth's most violent forces are stirring once again.
06:33Volcanoes seethe and fume, warming the planet.
06:52But some will pay a price for this warmer world.
06:57The North is still gripped by cold.
06:57The North is still gripped by cold.
07:26The North is still gripped by cold.
07:45As global temperatures continue to rise,
07:51the snow and ice all but disappear.
08:00Huge, meltwater rivers tear through the land.
08:11This thawing of the north is expanding the dinosaur's empire even further,
08:20and in surprising new ways.
08:30In this fresh, fertile landscape,
08:35sauropods no longer need to migrate.
08:39But it's also a new world for one of the dinosaur's oldest rivals,
08:48the pterosaurs.
08:51They are now bigger and badder than ever,
09:01including Gwydrako, the ghost dragon.
09:13But he's an intruder here.
09:21Because these trees are the home of longipteryx,
09:27a new kind of dinosaur.
09:31Less than 20 centimeters tall,
09:35but highly territorial,
09:38especially during nesting season.
09:55They're also equipped to take on the pterosaurs.
10:03Now they, too, can fly.
10:16In a previous era,
10:18flying dinosaurs like Ancyonis could only glide.
10:25Now they're able to flap their wings
10:28and maneuver with precision
10:30to strike at their enemies.
10:43They're fast and fearless.
10:58It only gets worse for the towering pterosaur.
11:04Because longipteryx are distant cousins
11:07of you, Tyrannus, the Snow King.
11:12They're armed with the teeth and claws of their clan.
11:28After ruling the skies since the Triassic,
11:33pterosaurs are now being matched by the dinosaurs.
11:46But as the dinosaurs fight to expand their empire into the air,
11:53an even greater revolution lies ahead.
12:06Not in the mountains,
12:08or the skies,
12:11or the oceans.
12:14The biggest twist in Earth's tale
12:18is unfolding quietly,
12:21almost in secret.
12:27Seven million years later,
12:31this new force is slowly rewriting the dinosaur story.
12:50This is one of the first flowers
12:53this forest has ever seen.
12:56Just one.
12:59And a vast and diverse new generation of plants.
13:07And they will become a phenomenon
13:11with the help of a close ally.
13:21Beetles.
13:24They carry pollen from one flower to the next.
13:36Nature's most reliable delivery service.
13:45helping these new plants spread far and wide,
13:49across the globe.
13:57Transforming the Dinosaurs Empire.
14:12But this new generation of plants has a dark side.
14:25While they need to attract pollinators, many are also evolved to repel herbivores with 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 are herd animals by nature.
15:25But this young stegosaur, barely two years old, is all alone.
15:39She is the last of her herd.
15:54To eat these tougher, new plants requires a mouth that can chew food in a way her primitive
16:02jaw cannot.
16:11She's starving.
16:27These once great herbivores are unable to adapt to this new world.
16:41It's one reason why their 50 million year existence will come to an end.
16:49Extinction.
16:59But in the wake of the stegosaur's demise, a new era will emerge.
17:11Over the next 15 million years, these new plants evolve and diversify.
17:20Spreading across the planet and ever further into the dinosaur's empire.
17:36The green revolution now covers the globe.
17:42And not just the land, but the water as well.
17:52Even providing cover and food for underwater explorers, like ankylosaurs.
18:27This bathing beauty is a different kind of dinosaur.
18:39He's a plant eater, like the stegosaurs.
18:44But a fancier one.
18:46Much fancier.
18:53It's not a good idea.
18:54Because unlike the stegosaurs, his advanced jaw can crush food in a way that makes eating
19:04any kind of plant easy.
19:22He wants to take full advantage of all this great kingdom has to offer, and he has a plan.
19:41It's a long trek, but 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 olives in his snout that amplify his song, so it can be heard far
20:47and wide.
21:31A female has answered his call.
21:37It's time to charm her with his deep, sultry humming.
21:49Then, he shows her his stylish armor.
22:04It's all very persuasive.
22:13It's time to save her.
22:16It's time to save her.
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,
23:16is now completely out of their reach.
23:25And there's a reason.
23:32At the very bottom of the ocean.
23:36A slow, imperceptible shift.
23:42Reshaping the planet.
23:51The seabed is fracturing.
23:55From 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.
24:55Over 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 Hetzig.
25:45Where isolation and evolution have created a kind of Neverland for the dinosaurs.
25:54A world where normal rules don't apply.
26:05This is the home of Magyarosaurus.
26:10A 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, which makes Magyarosaurus about the size of a pony.
26:47A sure is the area for thezufis of Hetzig.
26:54And, like, our family...
27:02On Hetzig where there's limited space and food.
27:08Sometimes smaller is better.
27:27But unlike Megiarosaurus, for predators, bigger is still better.
27:49As tall as a giraffe, one of the largest pterosaurs to ever live, the nightmare Hatsygopteryx.
28:09She'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 white on his feet.
29:12But being this small, he can't see the other side.
29:24They found a safe hiding spot, perfect for their size.

31:12The tiny dinosaurs, trapped on an island, has nowhere else to go.
31:21.
31:31But in a world so divided by the ocean, evolution takes different turns in different places.
31:49Ninety-six million years ago, sea levels are close to the highest they've ever been, creating
32:07a water world that no dinosaur has dared to enter.
32:20But that's about to change.
32:35Lurking in this mangrove swamp is a carnivore that has specially evolved to take on the
32:44final frontier.
32:56A dinosaur pioneer.
33:13Spinosaurus.
33:20The 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.
34:39Spinosaurus.
34:53Spinosaurus is adapted to a planet that is now molded.
34:57mostly ocean.
35:01And in this age, some of the largest prey is here in the water.
35:23Sharks.
35:29In a flat-out chase between a shark and a giant dog-paddling dinosaur,
35:35the shark 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.
36:25She's going to keep her safe.
36:26Now, all she needs to do is keep completely still.
36:48The best hunters are the patient ones.
36:54And her patience is starting to pay off.
37:01The best hunters are the patient ones.
37:06The blood in the water is drawing the sharks closer.
37:10And her.
37:24And her.
37:26She's coming in here.
37:26And her.
37:27And the нет.
37:29And the other thing is about her.
37:38The second hunter is showing her the sight of the shark,
37:54She doesn't move.
38:00She knows how this game is played.
38:23Brains and brawn, a killer combination that is finally letting the dinosaurs get a foothold
38:35in the ocean.
38:45Their reach is now global and extends to the very ends of the Earth, to what will one day
39:00be Antarctica?
39:11While Spinosaurus is stalking the shallow seas and the tropics, the world's southernmost
39:20landmass is not the frozen wilderness we know today.
39:27It'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.
40:48The End
40:50The End
40:55The End
40:57The End
41:01The End
41:08The End
41:14The End
