The Dinosaurs Episode 4
Transcript
00:15In the depths of space, a threat is looming.
00:22Trapped between the orbits of Jupiter and Mars,
00:28the asteroid is in the depths of space.
00:32One and a half million chunks of ancient rock circling the sun,
00:43drifting endlessly.
00:55But in a single moment of pure chance,
01:04one asteroid is thrown out of its orbit.
01:10A fleeting instant, millions of kilometers from Earth,
01:16sends it on a new trajectory towards the very center of our solar system.
01:34But its journey will come to a sudden and violent end in one of the most catastrophic events in Earth's
01:47history.
01:50And the final chapter in the epic story of the dinosaurs.
01:58It was.
01:59It was.
02:00It was.
02:04It was.
02:09It was.
02:29It was.
03:23It's three million years since the asteroid started its journey towards Earth.
03:31And the dinosaurs rule the planet.
03:35They dominate the land and are now entering the ocean as well.
03:44The high sea levels have split North America in two.
03:53Creating endless coastlines.
04:00Hundreds of tropical islands.
04:05And opportunity.
04:19But these islands are no paradise.
04:26They are home to a formidable predator.
04:34One of the fastest, most agile dinosaurs of its kind.
04:43North America's answer to the Spinosaurus.
05:01Just...not in the way you would think.
05:02Not even remotely.
05:08This is Hesperonis.
05:12He is formidable.
05:15And he is fast.
05:19But he's pretty much the opposite of his giant terrifying cousins.
05:35He's awkward.
05:37And clumsy.
05:41And has tiny teeth.
05:44Not exactly the traits of a ferocious hunter.
05:49But what he does share with Spinosaurus is that he's not confined to dry land.
06:04In fact, he's the most advanced aquatic dinosaur in history.
06:17Like some sort of prehistoric penguin.
06:22He's able to swim far out the sea to access feeding grounds.
06:28That were previously out of reach.
06:51This is the bounty of his new blue realm.
07:05Down here, his big clumsy feet become powerful propellers.
07:14And his ninety-four needle sharp teeth snatch fish with ease.
07:38But as an air breather, he's still tied to the surface.
07:55And the surface is not a safe place to linger.
08:03Because below, there are beasts.
08:09Twice the size of a killer whale.
08:27The apex predators of these seas.
08:33The apex predators of these seas.
08:41The apex predators of these seas.
08:42And the hyperlens break.
08:44The Heather.
08:44The cavalryム symbol.
08:50But the Musasaur moves with frightening speed.
08:56Luckily, Hesperoenus is much more agile.
09:08But he's exhausted, which gives the Mosasaur one last shot.
09:36Hesperoenus is a true survivor, venturing further into the ocean than any dinosaur ever has.
09:49But these waters are treacherous, even for the best swimmers.
10:03Despite the dinosaur's success in the shadows, the Mosasaurs rule the waves.
10:19800 miles north, on land, it's a different story.
10:37Fureled by a warm, stable climate, the dinosaur's dominance here is unrivaled.
10:53The great sora ponds are thriving among the tall trees, as they have since the dawn of the Jurassic.
11:08But down below, there has been a revolution.
11:18A female handersaw.
11:25While she may be dwarfed in present company, she's actually larger than an elephant.
11:34And she won't be held up by these giants.
11:39Because nothing can stop a mother on a mission.
11:45And that mission is to feed her family, who are somewhere down there.
12:07Long ago, their cheek-stuffing ancestors were scarce and scattered.
12:16But hadrosaurs are now so successful, their herds are thousands strong.
12:25The greatest gatherings of dinosaurs the world has ever known.
12:33But this female's family isn't traveling with the herd.
12:39They are in the safety of the creche.
12:43A sprawling nursery for hundreds of young hadrosaurs.
12:51Including her own.
12:58At six months old, they have insatiable appetites.
13:04And will eat almost anything she brings them.
13:11Anything.
13:24Feeding in this bird-like way takes a lot of refills.
13:30So, she's constantly leaving to go find food.
13:36And when mons are away, little ones will play.
14:05With the wingspan of a fighter jet, pterosaurs are now bigger.
14:11Than ever.
14:15And creches are the perfect hunting crowns.
14:19Where unguarded nests are the easiest pickings.
14:43The
14:44Despite the threat from this towering monster, the mothers will defend their babies at all costs.
15:07But the giant pterosaur is determined to feed.
15:19The screams from the nest are like a dinner bell to the predator.
15:25The screams from the nest are like a dinner bell to the predator.
15:40But the little ones aren't just crying in fear.
15:45They're calling for help.
15:47They're calling for help.
15:51They're calling for help.
16:07They're calling for help.
16:18But other dinosaurs are taking defense to a whole new level because the arms race between
16:28predator and prey is escalating.
16:33And this will give rise to the most iconic dinosaurs of all time.
16:45This will take so long that the continent of North America will shift, the land buckling
16:55up into the sky.
17:06The Rocky Mountains, it's here in the foothills below that the dinosaurs are making an impact.
17:30Pachycephalosaurus, using their outrageously thick skulls to do them for supremacy.
17:46And alongside them, a dinosaur with even more impressive headgear.
18:09She may look like a rhinoceros, but she's twice the size of one.
18:19And armed with spear-like horns over one meter in length.
18:32Triceratops and Pachycephalosaurus have impressive weapons.
18:40Yet there are some here that are even more armed and dangerous.
18:58Under the cover of darkness, the latest and greatest of the armored warriors.
19:10Triceratops and Pachycephalosaurus.
19:17Triceratops and Pachycephalosaurus.
19:24Triceratops and Pachycephalosaurus.
19:31Triceratops and Pachycephalosaurus.
19:43Triceratops and Pachycephalosaurus.
19:46Triceratops and Pachycephalosaurus.
19:48Triceratops and Pachycephalosaurus.
19:56Triceratops and Pachycephalosaurus.
19:59New weapon.
20:05A club-like tail,
20:06weighing half a ton,
20:09that he can use to take on whatever stalks these forests.
20:20He senses something.
20:30He senses something.
20:51His borders have been breached
20:55by the worst possible intruder of all.
21:12A Tyrannosaurus Rex.
21:14It looks so good.
21:44Let's go.
22:41Ankylosaurus versus T-Rex.
22:53An evolutionary stalemate.
22:57Millions of the years in the making.
23:20But in this arms race,
23:24there's one thing that does set these dinosaurs apart.
23:31Intelligence.
23:32Intelligence.
23:33No.
23:34No!
23:36No!
23:37No!
23:40No!
23:47No!
23:54No!
24:01No!
24:14T-Rex is one of the most fearsome predators of all time, and to remain at the top of
24:25her game, she must eat the equivalent of 200 steaks every day. And yet, so far, she hasn't
24:38eaten a single bite. That's because she has special plans for this take-out meal.
24:53But ankylosaurus is no light snack. Six tons of muscle and bone, with an assortment of
25:10lumps, and bumps. Even for T-Rex, it's quite a drag.
25:29T-Rex, it's quite a drag.
25:33T-Rex, it's quite a drag.
25:36T-Rex, it's quite a drag.
25:59T-Rex, it's quite a drag.
26:02Ooh.
26:04Finally, her journey's end.
26:17And the reason she's gone through all this effort...
26:34Five hungry hatchlings.
26:50A ferocious killer, yes, but also a devoted mother.
27:16She will ensure her little ones are well fed to give them the very best start in life, something
27:34their distant ancestors could only dream of.
27:42Far back in the Triassic, tiny Marasuchus hatched into hell.
27:50These dinosaurs in the making, forced to live in the shadows, hiding from the ruling reptiles.
28:03But when fate intervened, they turned catastrophe into opportunity and began their monumental
28:18rise, growing bigger, stronger, and ever more formidable.
28:34In time, they would triumph, not just on land, but in the sea and the sky.
28:47After 160 million years, the dinosaurs are now so dominant, nothing on earth can stand
28:59in their way.
29:06But something not of this earth will.
29:13Because as this family's journey is just getting started, another journey is approaching its end.
29:27The asteroid, now hurtling towards earth at 50 times the speed of sound, will finally have
29:37its date with destiny.
29:41It's the end.
29:54It's the end.
29:57It's the end.
29:58It's the end.
30:00It's the end.
30:01It's the end.
30:03The end.
30:13It's the end.
30:15It's the end.
30:15It's the end.
30:15It's the end.
30:16I'm sorry.
30:16To the frontier, you can describe to undefined.
30:18And it's the end.
30:24It's the end.
30:30They're playing.
30:31along with every living thing, for hundreds of kilometers.
30:44Far away in the foothills of the Rockies,
30:49these great dinosaurs have no idea
30:53what's about to hit them.
31:16The largest earthquakes in history.
31:28The largest earthquakes in history.
31:31What's about to come?
31:34An enormous wall of superheated debris explodes outward.
31:50zaaks
31:58The dinosaurs, caught beneath this death cloud...
32:03are entombed.
32:07The whole world is so hot,
32:10It literally bursts into flames.
32:21Even the toughest armor is no protection.
32:35The cloud quickly engulfs the entire planet.
32:40Suffocating it with ash.
32:44Shrouding it in darkness.
33:10Shrouding it.
33:17Shrouding it.
33:26Shrouding it.
33:32The few still standing at the end of the day are in a nightmare, choking in the gloom.
34:11By nightfall, the death toll for the dinosaurs is catastrophic.
34:47Starved of the sun's rays, an impact winter descends on the earth.
35:00Global temperature has dropped by 25 degrees Celsius, conditions too cold for almost any
35:12dinosaur to withstand.
35:27Giant sauropods laid to rest in the cinders of the buried trees that made them so tall.
35:52In their crowded colonies, those who lived together died together.
36:08Protective mothers cannot shield their young from their freezing temperatures.
36:20The punishing cold has also taken its toll on the most famous dinosaur of all.
36:36The tyrant king has fallen.
37:01Even the mighty tyrannosaurus rex will not survive this.
37:12Fly to the end of the world.
37:32The

37:39The reign of the dinosaurs has finally come to an end.
38:16But 66 million years later, the dinosaurs are rising again, this time at our hands.
38:41Today, their fossils stand as monuments to a lost world, but more than that, they are
38:52the keys that unlock the secrets of the dinosaur story.
38:59Our understanding of their lives is now greater than ever.
39:05From their very first moments to their very last.
39:14And the revelation that on Earth's darkest day, not all dinosaurs died.
39:24Some were small enough to find shelter from the apocalypse.
39:33And survive even to this day.
39:40The flying dinosaurs we now call the birds.
39:50And the clues to their past are hiding in plain sight.
40:17The remarkable journey that started 235 million years ago continues.
40:27Alongside us.
40:31They are the last remaining link.
40:35To a long lost kingdom.
40:39That was the age of the dinosaurs.
40:46Of course.
40:47Of course.
40:48Of course.
40:54Of course.
41:04押忍 Ante.
41:05And a few of them can bring it in themarish.
41:14So now, we have a curious story about it.
41:14By the way, there was an answer.
41:14They are the ones who died around the world.
41:17In the middle of the mountains.
41:19To the darkness we are.
41:24To be with the light.
