The Dinosaurs Episode 4 PrimeCut Series
Transcript
00:15In the depths of space, a threat is looming.
00:22Trapped between the orbits of Jupiter and Mars,
00:28the asteroid belt.
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,
01:17sends 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,
01:41in one of the most catastrophic events in Earth's history.
01:50And the final chapter in the epic story of the dinosaurs.
01:58Ones?
02:26Ones?
04:00Hundreds of tropical islands and 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.
05:00Just 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.
05:49But 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 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.
07:15And his 94 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.
08:04Because below, there are beasts.
08:08Twice the size of a killer whale.
08:21Mulsasaurs.
08:28The apex predators of these seas.
08:42Hesperoianus must get back to the shore.
08:50But the Musasaur moves with frightening speed.
08:56Luckily, Hesperoinus is much more agile, but he's exhausted, which gives the Mosasaur one
09:15last shot.
09:36Hesperoinus is a true survivor.
09:41Venturing 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 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 soror ponds are thriving among the tall trees, as they have since the dawn of
11:01the 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, their hedgehogs are a hundred.
12:16Long ago, their herd.
12:17But hadrosaws are now so successful, their herds are a thousand strong.
12:25The greatest gatherings of dinosaurs the world has ever known.
12:34But this female's family isn't traveling with the herd.
12:40There, in the safety of the creche, a sprawling nursery for hundreds of young hadrosaurs, including
12:52her own.
12:58At six months old, they have insatiable appetites, and 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.
13:41No!
13:46No!
13:49No!
13:50No!
13:55No!
13:56No!
13:57No!
13:59No!
14:00No!
14:02No!
14:03No!
14:06With the wingspan of a fighter jet, pterosaurs are now bigger than ever.
14:15And creches are the perfect hunting grounds, where unguarded nests are the easiest pickings.
14:43Despite 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.
15:24and the
15:45They're calling for help.
16:07This fear's instinct to protect their young
16:11is 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 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.
16:53The land buckling up into the sky.
17:06The Rocky Mountains.
17:11It's here in the foothills below
17:16that the dinosaurs are making an impact.
17:28Pachycephalosaurus.
17:31Using their outrageously thick skulls
17:37to do them for supremacy.
17:45Pachycephalosaurus.
17:46Pachycephalosaurus.
17:47And alongside them,
17:48a dinosaur with even more impressive headgear.
18:00Pachycephalosaurus.
18:10She may look like a rhinoceros.
18:13But she's twice the size of one.
18:19and armed with spear-like horns over one meter in length.
18:33Triceratops 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.
19:06Six meters long and highly territorial.
19:15Pachylosaurus, land of interest.
19:27He's on patrol for intruders.
19:31Bold enough to breach his borders.
19:42His tank-like torso is covered in dozens of thick, bony plates.
19:55And what's more, he has a powerful new weapon.
20:05A club-like tail, weighing half a ton.
20:09That he can use to take on whatever stalks these forests.
20:20He senses something.
20:23Yeet.
20:24Screams,
20:24You can't see me that's always.
20:39Like this.
20:42And when you're with a friend of the grenade,
20:44And you that's always a good start.
20:44And you're trying to do the power to the matter.
20:45You're trying to think of what you've seen in the fluoride.
20:46You're gonna guess.
20:46It's never going now.
20:47Maybe you're crying.
20:49You're leaving the Feuer.
20:51His borders have been breached by the worst possible intruder of all.
21:12A tyrannosaurus wrecks.
21:30He is the enemy.
21:32Him.
21:39He is the enemy.
21:46He is the enemy.
21:48He is the enemy.
21:53Let's go.
22:41Ankylosaurus versus T-Rex.
22:53An evolutionary stalemate.
22:56Millions of years in the making.
23:20But in this arms race...
23:23There's one thing that does set these dinosaurs apart...
23:31Intelligence.
23:32Hmm?
23:35Hmm?
23:47Hmm?
23:54Hmm?
24:01Hmm?
24:02Hmm?
24:04Hmm?
24:15T-Rex is one of the most fearsome predators of all time.
24:23And to remain at the top of her 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.
24:48Hmm?
24:51Hmm?
24:54Hmm?
24:54But Ankylosaurus is no light snack.
25:00Hmm?
25:02Hmm?
25:05Hmm?
25:09Hmm?
25:09Hmm?
25:12Hmm?
25:15Hmm?
25:16Hmm?
25:25Even for T-Rex, it's quite a drag.
25:29Hmm?
25:30Hmm?
25:30I don't know.
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.
26:54But also a devoted mother.
27:15She will ensure...
27:19Her little ones are well fed...
27:25To give them the very best start in life.
27:33Something 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...
28:11Into opportunity.
28:16And began their monumental rise.
28:21Growing bigger...
28:23Stronger...
28:25And ever more formidable.
28:33In time...
28:35They would triumph...
28:38Not just on land...
28:41But in the sea...
28:43And the sky.
28:47After 160 million years...
28:51The dinosaurs are now so dominant...
28:56Nothing on earth...
28:58Can stand in their way.
29:06But something not of this earth...
29:09Will.
29:12Because as this family's journey...
29:15Is just getting started...
29:18Another journey...
29:20Is approaching its end.
29:27The asteroid...
29:29Now hurtling towards earth...
29:32At 50 times the speed of sound...
29:35Will finally...
29:37Have its date with destiny.
30:12It smashes into the ocean...
30:16Off the coast of Mexico...
30:18With the power...
30:20Of a billion atomic bombs...
30:24Temperatures are hot enough...
30:26To vaporize the seabed.
30:30Along with every living thing...
30:33For hundreds of kilometers.
30:44Far away...
30:46In the foothills of the Rockies...
30:48These great dinosaurs...
30:51Have no idea...
30:52What's about to hit them.
31:16The largest earthquakes...
31:19In history.
31:22The largest whales...
31:24In history.
31:28But the worst...
31:31Is yet to come...
31:33In history.
31:35An enormous wall of...
31:37Superheated debris...
31:39Explodes 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, suffocating it with ash, shrouding it in darkness.
32:46The universe is so hot.
32:51The universe is so hot.
32:58The universe is so hot.
33:29The universe is so hot.
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 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.
35:53In 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.

37:39The 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.
38:48But 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.
39:25Some were small enough to find shelter from the apocalypse.
39:33And survived 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.
40:30They are the last remaining link to a long lost kingdom.
40:39That was the age of the dinosaurs.
40:46That was.
40:47That was.
40:48That was.
40:49That was.
40:56That was.
40:56That was.
40:59That was.
