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.
02:05It was.
02:06It was.
02:27It was.
02:30It 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.
03:43The high sea levels have split North America in two, creating endless coastlines.
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.
05:09This is Hesperonis.
05:13He is formidable.
05:15And he is fast.
05:19But he's pretty much the opposite of his giant terrifying cousins.
05:35He's awkward and clumsy and 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, he's able to swim far out the sea to access feeding
06:26grounds 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.
08:00And the surface is not a safe place to linger.
08:27The apex predators of these seas.
08:33The apex predators of these seas.
08:41The apex predators of these seas.
08:42The apex predators of these sharks.
08:44The chimble who have a giant婆-sher.
08:45The apex predators of these seas.
08:45The apex predators of these nice peas.
08:50The apex predators of these seas.
08:56The apex predators of these of these therese.
09:12...which gives the Mosasaur one last shot.
09:36Asperonis 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.
10:37Furelled 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.
12:16Long ago,aboys, the most part of her future.
12:17But 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
12:40they'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
16:22to 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
20:23he's on patrol for intruders
20:38he's on patrol
20:47between the two
20:48he's on patrol
20:51His borders have been breached by the worst possible intruder of all.
21:12A Tyrannosaurus Rex.
21:19Are you good?
21:53Let's go.
22:41Ankylosaurus versus T-Rex.
22:53An evolutionary stalemate, millions of 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.
23:32Intelligence.
23:32Oh!
23:35Oh!
23:38Oh!
23:39Oh!
23:47Oh!
23:51Oh!
24:03Oh!
24:05Oh!
24:06Oh!
24:07Oh!
24:07Oh!
24:07Oh!
24:09Oh!
24:09Oh!
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.
24:34And yet, so far, she hasn't eaten a single bite.
24:43That's because she has special plans for this takeout meal.
24:53But ankylosaurus is no light snack.
25:05Six tons of muscle and bone, with an assortment of lumps and bumps.
25:25Even for T-Rex, it's quite a drag.
25:29T-Rex, it's quite a drag.
26:05Finally, her journey's end, and the reason she's gone through all this effort…
26:34Five hungry hatchlings…
26:51A ferocious killer?
26:53Yes.
26:55…but 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, forced to live in the shadows, hiding from the ruling reptiles.
28:03But when fate intervened, they turned catastrophe into opportunity.
28:15And began their monumental rise.
28:22Growing bigger, stronger, and ever more formidable.
28:33In time, they would triumph.
28:37Not 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 in their way.
29:06But something not of this earth will.
29:12Because 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 its date with destiny.
29:54The钟ics are being captured, the city's
29:55The asteroid, that was absolutely magnificent.
29:56The sky, the moon's traced.
29:56The sky's shown.
29:56The sky's shown.
29:57The sky's shown.
29:58Yes, it's still here...
30:03The sky's shown.
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
30:47These 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
32:39Suffocating it with ash
32:44Shrouding it in darkness
33:10Should Hey
33:16It must be yours

33:32The few still standing at the end of the day are in a nightmare, choking in the gloom.
34:00The end of the day is the end of the day.
34:18The end of the day is the end of the day.
34:20The end of the day is the end of the day.
34:47Starved of the sun's rays, an impact winter descends on the earth.
35:00Global temperatures drop by 25 degrees Celsius, conditions too cold for almost any dinosaur
35:13to withstand.
35:27Giant sauropods laid to rest in the cinders of the very trees that made them so tall.
35:52In their crowded colonies, those who live together die 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.
37:10The end of the day is the end of the day is the end of the day.
37:39The reign of the dinosaurs has finally come to an end.
37:48The end of the day is the end of the day is the end of the day.
37:50The end of the day is the end of the day.
38:16But 66 million years later...
38:21...the dinosaurs are rising again.
38:30This time, at our hands.
38:41Today, their fossils stand as monuments to a lost world.
38:48But more than that...
38:50...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...
40:24...continues alongside us.
40:31They are the last remaining link...
40:34...to a long-lost kingdom...
40:38...that was...
40:41...the age...
40:44...of the dinosaurs.
