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.
02:10Oh, this must be.
02:11Well, it was.
02:28IING D完成 E acabo.
02:28I think.
02:28Lucky.
04:00Hundreds of tropical islands and opportunity.
04:20But 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.
05:00Just 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.
05:50But 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 that 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 94 needle sharp teeth snatch fish with ease.
07:38But as an air breather, he's still tied to the surface.
07:56And the surface is not a safe place to linger.
08:03Because below, there are beasts.
08:09Twice the size of a killer whale.
08:20Morsasaurs.
08:28The apex predators of these seas.
08:42Hesperonis must get back to the shore, but the Mosasaur moves with frightening speed.
08:56Luckily, Hesperonis is much more agile.
09:08But he's exhausted, which gives the Mosasaur one last shot.
09:36Hesperonis 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.
10:02Despite the dinosaur's success in the shadows, the Mosasaur's rule the waves.
10:19800 miles north, on land, it's a different story.
10:37Furelled by a warm, stable climate, the dinosaur's dominance here is unrivaled.
10:53The great soror 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.
11:24While 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, because 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.
12:13Long ago, the good.
12:16But hadrosaws are now so successful, their herds are thousand strong.
12:25The greatest gatherings of dinosaurs the world has ever known.
12:33but this female's family isn't traveling with the herd
12:40they're in the safety of the creche
12:43a sprawling nursery for hundreds of young hadrosaurs
12:51including her own
12:58at six months old
13:00they 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
13:28so she's constantly leaving to go find food
13:36and when moms are away
13:38little ones
13:40will play
14:05with the wingspan of a fighter jet
14:08pterosaurs are now bigger than ever
14:15and creches are the perfect hunting grounds
14:18where unguarded nests are the easiest pickings
14:44despite the threat from this towering monster
14:46despite the threat from this towering monster
15:07but the giant pterosaur is determined to feed
15:19the screams from the nest
15:22are like a dinner bell to the predator
15:41but the little ones aren't just crying in fear
15:44they're calling for help
16:07this fear's instinct to protect their young
16:10is central to the hydrosaur's remarkable success
16:18but other dinosaurs are taking defense to a whole new level
16:25because the arms race between predator and prey
16:29is escalating
16:33and this will give rise
16:35to the most iconic dinosaurs
16:38of all time
16:45this will take so long
16:47that the continent of north america
16:50will shift
16:53the land buckling up into the sky
17:06the rocky mountains
17:10it's here
17:12in the foothills below
17:15that the dinosaurs
17:17are making an impact
17:28pachycephalosaurus
17:31using their outrageously thick skulls
17:37to do them
17:39for supremacy
17:46and alongside them
17:48a dinosaur with even more impressive headgear
18:00triceratops
18:10she may look like a rhinoceros
18:13but she's twice the size of one
18:19and armed with spear-like horns
18:22over one meter
18:23in length
18:32triceratops
18:34triceratops
18:34and pachycephalosaurus
18:35have impressive weapons
18:40yet there are some here
18:42that are even more armed
18:45and dangerous
18:58under the cover of darkness
19:01the latest and greatest of the armored warriors
19:06six meters long
19:08and highly territorial

19:45in dozens of thick
19:47bony plates
19:55and what's more
19:57he has a powerful
19:58new weapon
20:04a club-like tail
20:06weighing half a ton
20:09that he can use
20:10to take on
20:11whatever stalks
20:12these forests
20:20he senses something
20:23would be
20:26un advantageous
20:50just
20:51Walah
20:51His borders have been breached by the worst possible intruder of all.
21:12A Tyrannosaurus Rex.
21:29A Tyrannosaurus Rex.
21:32A Tyrannosaurus Rex.
21:37A Tyrannosaurus Rex.
21:43Let's go.
22:13Let's go.
22:44Let's go.
23:20Let's go.
23:20But in this arms race, there's one thing that does set these dinosaurs apart.
23:31Intelligence.

24:59Go.
25:05Six tons of muscle and bone with an assortment of lumps and bumps.
25:25Even for T-Rex, it's quite a drag.
25:30.
25:34.
25:35.
26:03Finally.
26:06Her journey's end.
26:17And the reason she's gone through all this effort.
26:34Five hungry hatchlings.
26:50A ferocious killer?
26:52Yes.
26:55But also a devoted mother.
27:16She will ensure her little ones are well fed.
27:25To give them the very best start in life.
27:34Something their distant ancestors could only dream of.
27:42Far back in the Triassic, tiny Marasuchus hatched into hell.
27:50These dinosaurs in the making.
27:53Forced to live in the shadows.
27:57Hiding from the ruling reptiles.
28:03But when fate intervened.
28:07They turned catastrophe into opportunity.
28:15And began their monumental rise.
28:22Growing bigger, stronger, and ever more formidable.
28:34In time, they would triumph.
28:38Not just on land.
28:40But in the sea.
28:43And the sky.
28:48After 160 million years.
28:52The dinosaurs are now so dominant.
28:56Nothing on earth can stand in their way.
29:06But something not of this earth will.
29:12Because as this family's journey is just getting started.
29:18Another journey is approaching its end.
29:27The asteroid, now hurtling towards earth at 50 times the speed of sound.
29:35Will finally have its date with destiny.
29:41The asteroid, now hurtling towards earth at 50 times the speed of sound.
29:50The asteroid, now hurtling towards the sky.
30:01The asteroid, now hurtling towards the sky.
30:03The asteroid, now hurtling towards the sky.
30:12It smashes into the ocean off the coast of Mexico.
30:18With the power of a billion atomic bombs.
30:24Temperatures are hot enough to vaporize the seabed.
30:30Along with every living thing for hundreds of kilometers.
30:44Far away in the foothills of the Rockies.
30:48These great dinosaurs have no idea what's about to hit them.
31:16The largest earthquakes in history.
31:28But the worst is yet to come.
31:35An enormous wall of superheated debris explodes outward.
31:57The dinosaurs caught beneath this death cloud are entombed.
32:07Their world is so hot, it 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.
32:48Shrouding it in darkness.
33:09Shrouding it in darkness.
33:32The few still standing at the end of the day
33:38are 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,
35:08conditions too cold for almost any dinosaur to withstand.
35:27Giant sauropods laid to rest in the cinders of the buried trees
35:34that 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.
37:22VIRGORIOUS
37:29VIRGORIOUS
37:39The reign of the dinosaurs has finally come to an end.
38:16But 66 million years later, the dinosaurs are rising again.
38:30This time, at our hands.
38:42Today, their fossils stand as monuments to a lost world.
38:49But more than that, they are the 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.
40:26Alongside us.
40:31They are the last remaining link to a long lost kingdom that was the age of the dinosaurs.
40:46Of course.
40:47Of course.
41:00They are the flying civilizations.
41:01The flying dinosaurs will be buried.
41:03They will only bear the sky to the sky.
41:03The bay.
41:03In the last 90th century, the planet was buried.
41:11They were buried in the sea.
