00:17Two hundred and one million years ago, the dinosaur's world is collapsing beneath them.
00:35The continent of Pangea 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.
02:08Acidic 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 and 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.
04:04And it will change everything for the animals.
04:07And it will change everything for the animals.
04:08And it will change everything for the animals.
04:10The reign of the ancient reptiles is over.
04:17Kind of Mmmm, it will change everything for theautess.
04:53With their rivals out of the way, the dinosaurs now have a chance to rise from their ruins
05:07and conquer the world.
05:23To be continued...
06:28Two million years later, the dawn of the most famous era in Earth's history, the Jurassic.
06:48Pangea has split into two new landmasses.
06:57In the southern continent of Gondwana, life is thriving again.
07:08Pterosaurs have survived the destruction, the skies allowing them to seek refuge away from
07:18the chaos.
07:31There are now endless forests here.
07:37And they are filled with dinosaurs.
07:52Dinosaurs like Massospondylus.
08:02He's barely the height of a human, so 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, Volcanodon.
08:47At 11 meters long, she's more than twice the size of Massospondylus.
08:57She's part of a new branch of plant-eating dinosaurs known as the sauropods.
09:11Famous for their long necks and huge bodies that are supported by four legs instead of just
09:22two.
09:27These profound changes will help these giants become the largest animals to ever walk the earth.
09:40If Massospondylus can't compete, it will be left behind.
09:54While the sauropods are on the rise, another legend in the making is waiting in the wings.
10:15Caves like these are crawling with strange creatures.
10:23And one of them will give rise to some of the greatest dinosaurs in history.
10:50The tiny Heterodontosaurus.
11:09What makes him exceptional is hard to spot at first.
11:21One thing is clear, however, he's not one to back down from a challenge.
11:38Especially when there's food at stake.
11:48It'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 that allow him to devour almost anything.
12:26And that's not all.
12:29He also has cheek pouches where he can store food to eat later in safety.
12:35He is very proud to say.
12:36He is the most likely to be the greatest enemy in history.
12:39He is the only one to back down from a Jedi's side.
12:50But how does he do this?
12:53And that's all the world's history.
13:02He is the only one to keep the magic.
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,
13:22and 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.
14:31Hiding in the waters
14:34are the remnants of a once great empire.
14:50The reptiles.
15:00They are a deadly threat in these murky shallows, but they also need to be wary, because they
15:16no longer rule the Jurassic swamps.
15:28They have been usurped by those they once hunted on Pangea's shores.
15:40Dinosaurs.
15:47Dilophosaurus.
15:53With over 60 serrated teeth, she's twice the length of a polar bear.
16:09And a laser-focused hunter.
16:28Digital
16:29But in these flooded forests...
16:35There are creatures even more frightening than her.
16:40Here we go.
17:20Like a moth to a flame, she follows the mysterious calls.
18:01A male dilophosaurus.
18:08Larger and deadlier than her.
18:25He's drawn her hair for a reason.
18:36But it's not bloodlust.
18:39It's just plain lust.
18:45A coating ritual.
18:50Clawing at the ground is a display of strength.
18:56And to show off his virility, behold 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.
20:22But far below, the Earth itself poses a threat to their very existence.
20:46This time, from the Jurassic Seas.
21:02An alien world.
21:07Full 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.
22:54Are now a parched wasteland.
23:07The plants he relied on for food.
23:11Are nearly all gone.
23:19Many of his kind have died from starvation.
23:24And the rising temperatures have turned his home into a tinderbox.

24:08Let's go.
24:35Let's go.
24:37Their 17 million year existence brought to a tragic end.
25:08Eventually, other dinosaurs will rise to take their place.
25:19In that time, Earth's two continents will drift even further apart, creating a fragmented world
25:30with new lands for the dinosaurs to conquer.
25:56It's more than 20 million years since the fall of Masospundulus.
26:02And here in the mountains of what will one day be China, the climate has cooled.
26:12Life is flourishing.
26:23And a revolution is taking place.
26:44Within these cold dawn forests, something is stirring.
27:10The great four-legged dinosaurs.
27:27Mamentisaurus, a giant of the Jurassic.
27:51Nearly 40 million years after their ancestor, Fulcanodon, made its monumental rise.
28:00Mamentisaurus is now so gigantic that just standing up is a mammoth task.
28:08Mamentisaurus.
28:12Mamentisaurus.
28:27Mamentisaurus.
28:33Mamentisaurus.
28:34Mamentisaurus.
28:36Mamentisaurus.

29:00Mamentisaurus.
29:02Mamentisaurus.
29:08building and they're not the only giants that live in this forest the trees are
29:16reaching ever greater heights as well to avoid being completely consumed by
29:22these towering beasts
29:29but there is a catch to being this tall
29:35a 15 meter long neck can only support a tiny head
29:47that houses a brain smaller than an apple
30:10the evolutionary focus on size over smarts will help the sauropods become the most dominant herbivores
30:19of the jurassic age
30:34but they are not the only ones in this forest who are moving up in the world
30:50anky ornus
30:55yes he looks a bit like a chicken and he is about the size of one
31:01but he's nevertheless a dinosaur
31:10a dinosaur with feathers
31:14and newly evolved wings
31:38cyan raptor
31:43another dinosaur
31:48but one willing to hunt its own tiny cousin
32:10his primitive wings are next to useless on the ground
32:34but that doesn't mean he's confined to the ground
32:38the ground
32:39and
32:39the ground
32:39Let's go.
33:12Up here, his wings aren't just for show.
33:31He's one of the first dinosaurs to be able to glide.
33:44And with such skill, that he can even catch food midair.
33:55Flight will turn out to be one of the dinosaur's greatest leaps forward.
34:11But Ankyonis is still just a beginner here.
34:22For the time being, this airspace belongs to the pterosaurs.
34:41The flying dinosaurs are outgunned in the skies for now.
34:50But in time, the pterosaurs will meet their match.
35:03As the planet continues to evolve, so do the dinosaurs.
35:15And as the end of the Jurassic draws nearer,
35:21their control over the land on both continents is only getting stronger.
35:36It's seven million years since Ankyonis took to the air.
35:48Here, in what will one day be North America,
35:56geothermal heat simmers at the surface, an echo of past extinctions.
36:14The sauropods here are larger than ever.
36:22Their strategy of bigger is better is paying off.
36:31But these dinosaurs are evolving on an altogether different track.
36:43Stegosaurus.
36:49A far cry from their tiny, cheek-stuffing ancestors.
36:57They are now as heavy as elephants and equipped with armor, camouflage, and weapons.
37:09And here in the late Jurassic, they need the protection.
37:29Because there is danger in these dark forests.
37:42Allosaurus.
37:47Eight meters long, with dagger-like teeth,
37:52they are the most successful predators of their day.
38:02But this young male is not stalking.
38:08He's stealing.
38:16A female.
38:17A female.
38:22Same species.
38:24But larger.
38:26Stronger.
38:28And battle scarred.
38:29Three
38:30A male.
38:31In a body.
38:34Tenено.
38:50Personnel.
38:52A male.
38:56END SY ridenium online.
39:11The young male is lucky she didn't kill him.
39:41The young male is lucky she didn't kill him.
39:42The young male is lucky she didn't kill him.
39:59The rainstorms have passed.
40:05The young male hasn't eaten in weeks.
40:16He has no choice but to try his luck on a herd of Stegosaurus.
40:33But he can't hide his approach when he's out in the open.
40:39Which gives the herd time to prepare their defenses.
40:48They form a wall of moving bodies and spikes.
40:58It's intimidating and confusing for the young Allosaurus.
41:07He can't pick out which one to attack.
41:21But he's got other problems.
41:26The veteran female has just joined the game.
41:32And she's been playing this game for a lot longer than he has.
41:44She's able to isolate one of the herd.
41:52But Stegosaurus has evolved a perfect weapon.
41:57A mace-like tail with meter-long spikes called a thagomizer.
42:33A mace-like tail with meter-long spikes called a thagomizer.
42:37And a half-poilize bee- externally.
43:03For the female, it's game over.
43:12For the young male, it's payback.
43:18And lunch.
43:22Because Allosaurus are cannibals.
43:37Fifty million years after surviving an apocalypse,
43:41the dinosaur's dominion over Earth is now absolute.
43:59But the world they've come to know is changing.
44:10Temperatures are dropping across the globe.
44:18Bringing snow to the northern regions of the planet.
44:26Something few dinosaurs have ever experienced.
44:38From these frozen lands, a new kind of dinosaur will rise.
44:54The Tyrannosaurs are coming.
45:09The Tyrannosaurus and the Tyrannosaurus
45:11The Tyrannosaurus with the Tyrannosaurus
