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 in one of the most catastrophic events in Earth's
01:47history.
01:50And the final chapter in the epic story of the dinosaurs.
01:58Two dinosaurs.
02:15One mubedo,
02:17Neat Tanesh warp
02:18Two супers
02:20Four
02:27Six
03:54Hundreds of tropical islands and opportunity.
04:14But these islands are no paradise.
04:22One of the fastest, most agile dinosaurs of its kind.
04:31North America's answer to the Spinosaurus.
04:48Just not in the way you would think.
04:50Not even remotely.
04:56This is Hesperonis.
05:00He is formidable.
05:03And he is fast.
05:08But he's pretty much the opposite of his giant terrifying cousins.
05:23He's awkward.
05:25And clumsy.
05:29And has tiny teeth.
05:32Not exactly the traits of a ferocious hunter.
05:37But what he does share with Spinosaurus is that he's not confined to dry land.
05:52In fact, he's the most advanced aquatic dinosaur in history.
06:05Like some sort of prehistoric penguin.
06:10He's able to swim far out the sea to access feeding grounds.
06:15That were previously...
06:29New blue realm.
06:32New blue realm.
06:41Down here, his big clumsy feet become powerful propellers.
06:51And his ninety-four needle sharp teeth snatch fish with ease.
07:14But as an air breather, he's still tied to the surface.
07:32And the surface is not a safe place to linger.
07:40Because below, there are beasts.
07:45Twice the size of a killer whale.
07:56Molasaurs.
08:05The apex predators of the seas.
08:18Hesperonis must get back to the shore, but the Mosasaur moves with frightening speed.
08:32Luckily, Hesperonis is much more agile, but he's exhausted, which gives the Mosasaur one last shot.
09:12Hesperonis is a true survivor, venturing further into the ocean than any dinosaur ever has.
09:25But these waters are treacherous, even for the best swimmers.
09:38Despite the dinosaur's success in the shadows, the Mosasaurs rule the waves.
09:55800 miles north, on land, it's a different story.
10:13Furelled by a warm, stable climate, the dinosaurs.
10:23The Great Sauropods are thriving among the tall trees, as they have since the dawn of the Jurassic.
10:38But down below, there has been a revolution.
10:48A female handersaw.
10:55While she may be dwarfed in present company, she's actually larger than an elephant.
11:04And she won't be held up by these giants, because nothing can stop a mother on a mission.
11:15And that mission is to feed her family, who are somewhere down there.
11:37Long ago, their cheek-stuffing ancestors were scared now so successful, their herds are thousands strong.
11:49The greatest gatherings of dinosaurs the world has ever known.
11:58But this female's family isn't traveling with the herd.
12:04They are in the safety of the creche, a sprawling nursery for hundreds of young hadrosaurs.
12:15Including her own.
12:22At six months old, they have insatiable appetites.
12:27And will eat almost anything.
12:42Feeding in this bird-like way takes a lot of refills.
12:48So, she's constantly leaving to go find food.
12:54And when mons are away, little ones will play.
13:23With the wingspan of a fighter jet, pterosaurs are now bigger.
13:29Than ever.
13:33And creches are the perfect hunting crowns.
13:37Where unguarded nests are the easiest pickings.
13:55Despite the threat from this towering monster, the mothers will defend their babies at all costs.
14:19But the giant pterosaur is determined to feed.
14:31The screams from the nest are like a dinner bell to the predator.
14:37The screams from the nest are like a dinner bell to the predator.
14:53It's time to eat, all the other.
14:53But the little ones aren't just kids.
14:58But the little ones aren't just kids.
15:12This fear's instinct to protect their young is central to the hydrosaur's remarkable success.
15:24But other dinosaurs are taking defense to a whole new level.
15:32Because the arms race between predator and prey is escalating.
15:39And this will give rise to the most iconic dinosaurs of all time.
15:51This will take so long that the continent of North America will shift.
15:59The land buckling up into the sky.
16:12The Rocky Mountains.
16:17It's here in the foothills below that the dinosaurs are making an impact.
16:35Pachycephalosaurus.
16:37Using their outrageously thick skulls.
16:44To do them for supremacy.
16:52And alongside them, a dinosaur with even more impressive headgear.
17:06Triceratops.
17:13But she's twice the size of one.
17:19And armed with spear-like horns over one meter in length.
17:30Massive weapons.
17:34Yet there are some here that are even more armed and dangerous.
17:52Under the cover of darkness.
17:55The latest and greatest of the armored warriors.
18:00Six meters long and highly territorial.
18:09Ankylosaurus.
18:10Magnibentris.
18:11Magnibentris.
18:20He's on patrol for intruders.
18:25Bold enough to breach his borders.
18:37His tank-like torso is covered in dozens of thick, bony plates.
18:43And what's more.
18:45He has a powerful new weapon.
18:52A club-like tail.
18:54Weighing half a ton.
18:57That he can use to take on whatever stalks these forests.
19:08He senses something.
19:33His borders have been breached.
19:37By the worst possible intruder of all.
19:54A Tyrannosaurus Rex.
19:56Yeah.
19:56He almost never agreed to zones.
20:01Goodbye, Tyrarnosaurus.
20:05All along.
20:21Weamentos have been duplicated in a trap here.
20:24Let's go.
20:54Let's go.
21:30Let's go.
21:34Let's go.
21:35Let's go.
21:43Let's go.
21:57Let's go.
22:00Intelligence.
22:01Let's go.
22:04Let's go.
22:06Let's go.
22:09Let's go.
22:24Let's go.
22:26Let's go.
22:31Let's go.
22:46Let's go.
23:05Let's go.
23:15Let's go.
23:30Let's go.
23:35Let's go.
23:36Let's go.
23:39Let's go.
23:43Let's go.
23:46Let's go.
24:01Let's go.
24:02Let's go.
24:10Let's go.
24:13Let's go.
24:21Let's go.
24:24Let's go.
24:35And the reason she's gone through all this effort...
24:52Five hungry hatchlings.
25:08A ferocious killer? Yes.
25:14But also... a devoted mother.
25:34She will ensure... her little ones are well fed...
25:43...to give them the very best start in life...
25:48...to only dream of.
25:54Far back in the Triassic, tiny Marasuchus hatched into hell.
26:02These dinosaurs in the making...
26:06...forced to live in the shadows...
26:09...hiding from the ruling reptiles.
26:15But when fate intervened...
26:19...they turned catastrophe...
26:23...into opportunity.
26:27And began their monumental rise.
26:33Growing bigger, stronger...
26:37...and ever more formidable.
26:46In time...
26:48...they would triumph...
26:50...not just on land...
26:52...but in the sea...
26:56...and the sky.
26:59After 160 million years...
27:03...the dinosaurs are now so dominant...
27:08...nothing on earth...
27:10...can stand in their way.
27:12...not of this earth...
27:15...will.
27:19Because as this family's journey...
27:21...is just getting started...
27:24...another journey...
27:26...is approaching its end.
27:33The asteroid...
27:35...now hurtling towards earth...
27:37...and its date with destiny.
27:44To the moon he was again.
27:47The planet is too open...
27:50...and the sea.
27:51For what if the destroyer...
27:52...the sea?
27:54To the sea!
27:56To the sea!
28:04...just in the sea!
28:04To the sea!
28:05In the sea.
28:06To the sea!
28:07To the sea!
28:07It smashes into the ocean...
28:10...off the coast of Mexico.
28:12With the power of a billion atomic bombs, temperatures are hot enough to vaporize the seabed, along with every living
28:26thing for hundreds of kilometers.
28:37Great dinosaurs have no idea what's about to hit them.
29:04The largest earthquakes in history.
29:17But the worst is yet to come.
29:23An enormous wall of superheated debris explodes outward.
29:46The dinosaurs, caught beneath this death cloud, are entombed.
29:52The dinosaurs, caught beneath this death cloud, are entombed.
29:55Their world is so hot, it literally burns.
29:59Bursts into flames.
30:04Even the toughest armor, is no protection.
30:13The entire planet, suffocating it with ash, shrouding it in darkness.
30:30The moon is set with the moon.
30:30The moon is set with the moon.
30:30It is always the one that I am the most of them.
30:31The moon is set with it.
30:36The moon is set with war, but the moon is set with fire.
31:08The few, still standing at the end of the day, are in a nightmare, choking in the gloom.
31:50The few, still standing at the end of the day, are in a nightmare, choking in the gloom.
31:52For the dinosaurs, is catastrophic.
32:25In the days, an impact winter descends on the earth.
32:36Global temperatures drop by 25 degrees Celsius, conditions too cold for almost any dinosaur
32:49to withstand.
33:03Giant sauropods laid to rest in the cinders of the buried trees that made them so tall.
33:28In their crowded colonies, those who live together, die together.
33:44Protective mothers cannot shield their young from their freezing temperatures.
33:56The punishing cold has also taken its toll on the most famous dinosaur of all.
34:12The tyrant king has fallen.
34:37Even the mighty tyrannosaurus rex will not survive this.
34:43The tyrant king has fallen.
34:46The tyrant.
34:50The tyrant.
34:57The tyrant.
35:00The tyrant.
35:03The Tyrant.
35:03The tyrant.
35:15The tyrant.
35:16Thearynge.
35:16The tyrant.
35:20VAL世界.
35:22The tyrant.
35:52The End
35:5326 million years later,
35:58the dinosaurs are rising again.
36:06This time, at our hands.
36:17Today, their fossils stand as monuments to a lost world.
36:24But more than that,
36:27they are the keys that unlock the secrets of the dinosaur story.
36:35Our understanding of their lives is now greater than ever.
36:41From their very first moments to their very last.
36:50And the revelation that on Earth's darkest day, not all dinosaurs died.
37:00Some were small enough to find shelter from the apocalypse.
37:09And survive even to this day.
37:16The flying dinosaurs, we now call the birds.
37:26And the clues to their past are hiding in plain sight.
37:53The remarkable journey that started 235 million years ago,
38:00continues alongside us.
38:07They are the last remaining link
38:11to a long lost kingdom
38:15that was the age of the dinosaurs.
38:22of course.
38:51of course.
38:51of course.

39:21of course,
