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,
01:16sends 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,
01:41in one of the most catastrophic events in Earth's history.
01:50And the final chapter in the epic story of the dinosaurs.
02:00The imminent Japanese
02:04It is a kill-born
02:12To be continued....
02:13The End
02:14The End
02:15Lytzer
02:16The End
02:16The End
02:20Let's go.
02:46Let's go.
03:16Let's go.
03:23It's three million years since the asteroid started its journey towards Earth.
03:30And 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, hundreds
04:01of tropical islands, and opportunity.
04:19But these islands are no paradise.
04:26They are home to a formidable predator, one of the fastest, most agile dinosaurs of its
04:39kind.
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.
05:20But 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.
08:19As S dolphins famoso.
08:22And it's been sent out West Susan.
08:42Hesperonis must get back to the shore, but the Mosasaur moves with frightening speed.
08:56Luckily, Hesperonis is much more agile, but he's exhausted, which gives the Mosasaur one last
09:32shot.
09:36Hesperonis 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.
10:37Furelled by a warm, stable climate, the dinosaur's dominance here is unrivaled.
10:53The great sauropods are thriving among the tall trees, as they have since the dawn of the
11:01Jurassic.
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.
12:16But hadrosaurs are now so successful, their herds are thousands strong.
12:26The greatest gatherings of dinosaurs the world has ever known.
12:33But 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
12:51her 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 moms are away, little ones will play.
13:41They're finally coming back.
14:15and crèches 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.
15:20The 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.
15:51No!
16:06This fierce instinct to protect their young is 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.
16:52The land buckling up into the sky.
17:06The rocky mountains.
17:11It's here, in the foothills below, that the dinosaurs are making an impact.
17:28Pachycephalosaurus.
17:31Using their outrageously thick skulls.
17:37To duel for supremacy.
17:45Pachycephalosaurus.
17:46Pachycephalosaurus.
17:47And alongside them, a dinosaur with even more impressive headgear.
18:00Pachycephalosaurus.
18:10Pachycephalosaurus.
18:11rhinoceros, but she's twice the size of one and armed with spear-like horns over
18:22one 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.
19:15Ankylosaurus, Magnaventris.
19:26He'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.
19:54And what's more, he has a powerful new weapon.
20:04A club-like tail, weighing half a ton, that he can use to take on whatever stalks these forests.
20:19He senses something.
20:21Ugh!
20:24Banana.
20:48highly vampires
20:49and refugeesăă
20:50what
20:50have youamed? A
20:50friend, an
20:51overlord.
20:51His borders have been breached
20:55by the worst possible intruder of all.
21:12A Tyrannosaurus Rex.
21:28A Tyrannosaurus Rex.
21:31There he is.
21:43Let's go.
22:02Let's go.
22:32Let's go.
22:40Ankylosaurus versus T-Rex.
22:53An evolutionary stalemate.
22:56Millions of the years in the making.
23:19But in this arms race,
23:23there's one thing that does set these dinosaurs apart.
23:31Intelligence.
23:31Hmm.
23:34Hmm.
23:37Hmm.
23:50Hmm.
24:14T-Rex is one of the most fearsome predators of all time.
24:22And to remain at the top of her game,
24:27she 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.
25:56So Drew can be able to use Ma-A
26:05Finally, her journey's end.
26:17And the reason she's gone through all this effort
26:34Five hungry hatchlings.
26:51A ferocious killer, yes, but also a devoted mother.
27:16She will ensure her little ones are well fed to give them
27:26the 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,
27:57hiding from the ruling reptiles.
28:03But when fate intervened, they turned catastrophe into opportunity.
28:15And began their monumental rise.
28:21Growing 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 in their way.
29:06But something not of this earth will.
29:13Because 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,
29:34will finally have its date with destiny.
29:39The planet is coming and the the sky.
29:39I don't know.
30:12It smashes into the ocean off the coast of Mexico with the power of a billion atomic bombs.
30:24Temperatures are hot enough to vaporize the seabed, along with every living thing for hundreds of kilometers.
30:44Far away in the foothills of the Rockies, these 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.
31:34An 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, suffocating it with ash, shrouding it in darkness.
33:15And there's no passion for it in the States.
33:16The dedicators are turned highest on the wall of much any force.
33:32The few, still standing at the end of the day, are in a nightmare, choking in the gloom.
34:14The few, still standing at the end of the day, are in a nightmare, choking in the gloom.
34:16For the dinosaurs, is catastrophic.
34:49Today, an impact winter descends on the Earth.
35:00Global temperature is 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.
37:09The tyrant.
37:10The tyrant.
37:22The tyrant.
37:24The tyrant.
37:25The tyrant.
37:35The tyrant.
37:39The tyrant.
37:41The tyrant.
37:43The tyrant.
37:45To be a return of this antithesis.
37:55The End
38:16But 66 million years later,
38:21the dinosaurs are rising again.
38:30This time, at our hands.
38:41Today, their fossils stand as monuments to a lost world.
38:47But more than that, they are the keys that unlock the secrets of the dinosaur story.
38:59Today, our understanding of their lives is now greater than ever, from their very first
39:07moments 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, and 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 to a long-lost kingdom that was the age of the dinosaurs.
40:46Of course.
40:47Of course.
40:54Of course.
40:59Of course.
41:01We are the last 159 million years later.
41:05Of course.
41:07Of course.
41:08Of course.
41:16Of course.
41:17And the dream of the universe was the age of the sky.
41:18Of course.
41:21Of course.
41:22Of course.
41:30The dream of the Earth's highest.
