00:17201 million years ago, the dinosaur's world is collapsing beneath them.
00:35The continent of Pangaea is tearing apart, creating a great divide and a molten apocalypse for any creature caught in
00:56this hell.
01:13For both reptiles and dinosaurs, escape is impossible.
01:31But the worst is yet to come.
01:38An invisible killer is choking the air itself.
01:49Clouds of toxic gases wreak devastation.
02:08A city fog poisons everything in its path.
02:35As the gases in the atmosphere grow thicker, temperatures soar.
02:43Annihilating three quarters of all plant species.
02:49And millions of animals across the planet.
03:11It's known as the End Triassic Mass Extinction.
03:16And it will change everything for the dinosaurs.
03:24Because their versatility and ability to adapt help them survive this catastrophe far better than the reptiles.
03:37So let's see.
03:44Let's go.
04:10The reign of the ancient reptiles is over.
04:53With their rivals out of the way,
04:58the dinosaurs now have a chance to rise from their ruins
05:07and conquer the world.
05:12Let's go.
05:12Let's go.
05:20Let's go.
05:22Let's go.
05:24Let's go.
05:37Let's go.
05:41Let's go.
05:47Let's go.
05:49Let's go.
05:50Let's go.
05:52Let's go.
05:53Let's go.
06:04Let's go.
06:27Two million years later,
06:32Pangea, the dawn of the most famous era in Earth's history,
06:40the Jurassic.
06:48Pangea has split into two new land masses.
06:57In the southern continent of Gondwana,
07:03life is thriving again.
07:08Terror swords have survived the destruction.
07:14The sky is allowing them to seek refuge away from the chaos.
07:30There are now endless forests here.
07:36And they are filled with dinosaurs.
07:52Dinosaurs like Massospondylus.
08:02He's barely the height of a human,
08:05so it's hard to reach the freshest food high in the trees.
08:21But he's got a bigger problem.
08:25A newly evolved rival.
08:40Volcanodon.
08:47At 11 meters long,
08:50she's more than twice the size of Massospondylus.
08:57She's part of a new branch of plant-eating dinosaurs,
09:01known as the sauropods.
09:11famous for their long necks and huge bodies
09:17that are supported by four legs instead of just two.
09:27These profound changes will help these giants
09:32become the largest animals to ever walk the Earth.
09:40If Massospondylus can't compete,
09:44it will be left behind.
09:54While the sauropods are on the rise,
10:01another legend in the making
10:02is waiting in the wings.
10:15Caves like these are crawling with strange creatures.
10:23And one of them will give rise
10:27to some of the greatest dinosaurs in history.
10:50the tiny Heterodontosaurus.
11:09What makes him exceptional
11:11is hard to spot at first.
11:21One thing is clear, however,
11:27he's not one to back down from a challenge.
11:39Especially when there's food at stake.
11:49It's all about the food.
12:03He may only weigh as much as a chihuahua,
12:09but he does have a superpower.
12:12An incredibly strong beak and jaw
12:15that allow him to devour almost anything.
12:26And that's not all.
12:29He also has cheek pouches where he can store food
12:33to eat later in safety.
12:35the sea.
12:53I'm putting all the
12:55But I keep reading.
12:55I'll be careful.
12:55Which is something that takes a breathes
12:55to help?
12:55How do you know?
12:55How do you know?
13:05What's going on?
13:05I was about to run away.
13:05This multi-tooled mouth will allow his descendants
13:10to become some of the greatest dinosaurs of all time.
13:18Descendants like the mighty Stegosaurus,
13:21and even Triceratops.
13:26From small beginnings, great things can grow.
13:45But the dinosaurs will need more than cheek pouches
13:49to conquer the planet.
13:54On the northern side of the Great Divide
13:58lies the other new continent, Loresia.
14:05Blablabla
14:29Blablabla
14:30And the believers stone!
14:35The remnants of a once great empire.
14:50The reptiles.
15:00They are a deadly threat in these murky shadows.
15:06But they also need to be wary.
15:15Because they no longer rule the Jurassic swamps.
15:27They have been usurped
15:30by those they once hunted on Pangea's shores.
15:40Dinosaurs.
15:48Dylophosaurus.
15:52With over 60 serrated teeth,
15:57she's twice the length of a polar bear.
16:09And a laser-focused hunter.
16:28But in these flooded forests,
16:35there are creatures
16:37even more frightening than her.
16:44The
16:44The
16:44The
16:44The
16:44The
16:52I don't know.
17:20Like a moth to a flame, she follows the mysterious cause.
18:01A male Dilophosaurus, larger and deadlier than her.
18:25He's drawn her hair for a reason, but it's not bloodlust, it's just plain lust.
18:45According ritual, clawing at the ground is a display of strength, and to show off his virility,
18:59behold his crimson head crest.
19:16Finally, the grand finale.
19:23The song of the Swamp King.
19:45For a ferocious predator, he's remarkably gifted.
19:57But the future of her bloodline depends on her choice.
20:02And he's just not gifted enough.
20:17Ensuring the continuation of their species is critical.
20:23But far below, the Earth itself poses a threat to their very existence.
20:47This time, from the Jurassic Seas.
21:02An alien world, full of bizarre creatures.
21:23The most dangerous of them all.
21:28The pliosaurs.
21:34The great sea monsters that rule the oceans.
21:41They are one reason that dinosaurs have not entered this frontier.
21:50But the real threat to the dinosaurs lies below.
22:03Methane.
22:14This greenhouse gas was frozen under the seabed for millions of years.
22:23But warming oceans are causing it to leach out.
22:28With a devastating sound effect for the entire globe.
22:42Extreme heat.
22:49The endless forests that Massospondylus once roamed are now a parched wasteland.
23:07The plants he relied on for food are nearly all gone.
23:19Many of his kind have died from starvation.
23:24And the rising temperatures have turned his home into a tender box.
23:57The
23:57Miserish
23:58The
24:25It's the final nail in the coffin.
24:28It's the final nail in the coffin for Massospundilus.
24:38It's the final nail in the coffin.
25:08In that time, Earth's two continents will drift even further apart, creating a fragmented world
25:18with new lands for the dinosaurs to conquer.
25:45It's more than 20 million years since the fall of Massospundilus.
25:51And here in the mountains of what will one day be China, the climate has cooled.
26:00Life is flourishing.
26:11And a revolution is taking place.
26:32Within these cold dawn forests, something is stirring.
26:58The great four-legged dinosaurs.
27:15Mamentisaurus, a giant of the Jurassic.
27:39Nearly 40 million years after their ancestor, Fulcanodon, made its monumental rise.
27:48Mamentisaurus is now so gigantic that just standing up is a mammoth task.
27:56Mamentisaurus.
28:09Mamentisaurus.
28:14Mamentisaurus.
28:16Mamentisaurus.
28:22Mamentisaurus.
28:23Mamentisaurus.
28:24Mamentisaurus.
28:24Mamentisaurus.
28:27Mamentisaurus.
28:28Mamentisaurus.
28:29Mamentisaurus.
28:31Mamentisaurus.
28:32Mamentisaurus.
28:42Mamentisaurus.
28:43Mamentisaurus.
28:44Mamentisaurus.
28:45Mamentisaurus.
28:46Mamentisaurus.
28:47that can reach as high as a five-story building.
28:57And they're not the only giants that live in this forest.
29:02The trees are reaching ever greater heights as well
29:06to avoid being completely consumed by these towering beasts.
29:17But there is a catch to being this tall.
29:23A 15-meter-long neck can only support a tiny head...
29:35that houses a brain smaller than an apple.
29:58The evolutionary focus on size over smarts will help the sauropods become the most dominant herbivores of the Jurassic Age.
30:22But they're not the only ones in this forest who are moving up in the world.
30:38Anki Ornis.
30:42Yes, he looks a bit like a chicken.
30:46And he is about the size of one.
30:51But he's nevertheless a dinosaur.
30:58A dinosaur with feathers.
31:03And newly evolved wings.
31:27Cynraptor.
31:32Another dinosaur.
31:37But one willing to hunt its own tiny cousin.
31:58his primitive wings are next to useless on the ground.
32:22His primitive wings are next to useless on the ground.
32:25And he's blind to the ground.
33:01Up here, his wings aren't just for show.
33:20He's one of the first dinosaurs
33:23to be able to glide.
33:32And with such skill
33:35that he can even catch food mid-air.
33:43Flight will turn out to be
33:46one of the dinosaurs' greatest leaps forward.
33:59But Anchionis is still just a beginner here.
34:11For the time being,
34:14this airspace
34:19belongs to the pterosaurs.
34:29The flying dinosaurs are outgunned in the skies for now.
34:39But in time, the pterosaurs will meet their match.
34:52As the planet continues to evolve,
34:56so do the dinosaurs.
35:03And as the end of the Jurassic draws nearer,
35:09their control over the land,
35:12on both continents,
35:14is only getting stronger.
35:25It's seven million years since Anchionis took to the air.
35:36Here, in what will one day be North America,
35:44geothermal heat
35:46simmers at the surface.
35:50An echo of past extinctions.
36:02The sauropods here are larger than ever.
36:10Their strategy of bigger is better
36:13is paying off.
36:19But these dinosaurs are evolving
36:23on an altogether different track.
36:31Stegosaurus.
36:37A far cry from their tiny cheek-stuffing ancestors.
36:46They are now as heavy as elephants.
36:49And equipped with armor,
36:52camouflage,
36:53and weapons.
36:57And here in the late Jurassic,
37:00they need the protection.
37:17Because there is danger in these dark forests.
37:30Allosaurus.
37:36And here in the late Jurassic Park.
37:36Eight meters long,
37:38with dagger-like teeth,
37:40they are the most successful predators
37:43of their day.
37:50But this young male is not stalking.
37:56He's stealing.
38:04A female.
38:10Same species.
38:12But larger.
38:14Stronger.
38:16And battle-scarred.
38:17The twoẻ...
38:21The three-year.
38:23The two-year.
38:25The five-year.
38:33Theûta.
38:34The hero.
38:42The third one.
38:44The two-year.
38:59The young male is lucky she didn't kill him.
39:23The young male is lucky she didn't kill him.
39:27The young male is lucky she didn't kill him.
39:48The rainstorms have passed.
39:54The young male hasn't eaten in weeks.
40:04He has no choice but to try his luck on a herd of Stegosaurus.
40:21But he can't hide his approach when he's out in the open.
40:27Which gives the herd time to prepare their defenses.
40:37They form a wall of moving bodies and spikes.
40:46It's intimidating and confusing for the young Allosaurus.
40:55He can't pick out which one to attack.
41:09But he's got other problems.
41:15The veteran female has just joined the game.
41:20And she's been playing this game for a lot longer than he has.
41:33She's able to isolate one of the herd.
41:41But Stegosaurus has evolved a perfect weapon.
41:47A mace-like tail with meter-long spikes.
41:52Called a thagomizer.
41:54Gaatito.
41:56Gaatito.
42:22Pleasure.
42:24Because of the groaning vaccine faces have been vanished.
42:51For the female,
42:53it's game over.
43:00For the young male, it's payback and lunch because Allosaurus are cannibals.
43:25Fifty million years after surviving an apocalypse, the dinosaur's dominion over Earth is now absolute.
43:47But the world they've come to know is changing.
43:58Temperatures are dropping across the globe.
44:07Bringing snow to the northern regions of the planet, something few dinosaurs have ever experienced.
44:26From these frozen lands, a new kind of dinosaur will rise.
44:41The Tyrannosaurus are coming.
44:45The Tyrannosaurus.
44:48The Tyrannosaurus.
44:51The Tyrannosaurus.
44:53The Tyrannosaurus.
44:57The Tyrannosaurus.
45:01The Tyrannosaurus.
45:02The Tyrannosaurus.
