1
00:00:17,559 --> 00:00:20,478
Two hundred and one million years ago…

2
00:00:23,023 --> 00:00:27,235
the world of dinosaurs
It's crumbling beneath them.

3
00:00:36,494 --> 00:00:40,248
The continent of Pangea is breaking apart…

4
00:00:45,462 --> 00:00:47,797
creating a huge rupture…

5
00:00:50,258 --> 00:00:52,427
and a fiery apocalypse

6
00:00:53,636 --> 00:00:57,182
for any trapped creature
in this hell.

7
00:01:14,074 --> 00:01:16,951
So much for the reptiles
As for dinosaurs…

8
00:01:19,537 --> 00:01:22,916
escaping is impossible.

9
00:01:31,299 --> 00:01:34,052
But the worst is yet to come.

10
00:01:38,932 --> 00:01:44,104
An invisible killer
makes the air suffocating.

11
00:01:49,901 --> 00:01:52,320
Toxic gas clouds

12
00:01:52,987 --> 00:01:55,031
cause destruction.

13
00:02:08,878 --> 00:02:10,463
An acidic fog

14
00:02:12,090 --> 00:02:14,884
poisons everything in its path.

15
00:02:35,864 --> 00:02:39,367
As gases in the atmosphere
become denser,

16
00:02:39,868 --> 00:02:42,245
temperatures soar,

17
00:02:43,413 --> 00:02:47,000
annihilating three quarters
of all plant species

18
00:02:48,960 --> 00:02:52,839
and millions of animals across the planet.

19
00:03:11,691 --> 00:03:17,363
It became known as the mass extinction
from the end of the Triassic

20
00:03:18,740 --> 00:03:23,745
and it will change everything for the dinosaurs,

21
00:03:25,663 --> 00:03:30,335
because the versatility
and their ability to adapt

22
00:03:30,418 --> 00:03:33,463
will help them survive this catastrophe

23
00:03:34,130 --> 00:03:37,717
much better than reptiles.

24
00:04:11,709 --> 00:04:16,214
The reign of ancient reptiles is over.

25
00:04:54,168 --> 00:04:56,713
With rivals out of the way...

26
00:04:59,048 --> 00:05:03,344
dinosaurs now have the chance
to rise from the ruins…

27
00:05:07,682 --> 00:05:11,394
and conquer the world.

28
00:06:10,203 --> 00:06:14,540
THE DINOSAURS

29
00:06:25,385 --> 00:06:28,554
CHAPTER 2: CONQUEST

30
00:06:28,638 --> 00:06:30,973
Two million years later,

31
00:06:32,934 --> 00:06:37,230
the beginning of the most famous period
of the History of the Earth.

32
00:06:37,730 --> 00:06:40,441
199 MILLION YEARS AGO
JURASSIC PERIOD

33
00:06:40,525 --> 00:06:41,943
Jurassic Period.

34
00:06:48,366 --> 00:06:53,454
Pangea split
on two new landmasses.

35
00:06:58,042 --> 00:07:00,711
On the southern continent of Gondwana…

36
00:07:03,089 --> 00:07:06,217
life prospers again.

37
00:07:08,761 --> 00:07:11,848
Pterosaurs survived the destruction.

38
00:07:14,475 --> 00:07:19,564
Heaven allows
May they seek refuge away from the chaos.

39
00:07:31,701 --> 00:07:35,788
Now there are endless forests here.

40
00:07:37,665 --> 00:07:41,711
And they are full of dinosaurs.

41
00:07:53,181 --> 00:07:56,976
Dinosaurs like Massospondylus.

42
00:08:02,690 --> 00:08:05,067
He barely reaches the height of a human being,

43
00:08:05,568 --> 00:08:10,031
so it's hard to reach fresh food
high in the trees.

44
00:08:21,542 --> 00:08:23,711
But he has a bigger problem.

45
00:08:26,255 --> 00:08:28,799
A newly evolved rival.

46
00:08:39,519 --> 00:08:41,103
Vulcanodon.

47
00:08:47,985 --> 00:08:49,904
11m long,

48
00:08:50,571 --> 00:08:54,200
he has more than double
the size of Massospondylus.

49
00:08:57,036 --> 00:09:00,790
He's part of a new group
of herbivorous dinosaurs

50
00:09:02,041 --> 00:09:03,334
known as…

51
00:09:05,002 --> 00:09:06,796
sauropods.

52
00:09:11,759 --> 00:09:14,011
Famous for their long neck

53
00:09:14,804 --> 00:09:16,347
and huge body,

54
00:09:17,848 --> 00:09:23,145
they are supported by four legs,
instead of just two.

55
00:09:28,067 --> 00:09:32,363
These big changes
will help these giants

56
00:09:32,446 --> 00:09:36,951
to become the biggest animals
who have ever walked the Earth.

57
00:09:41,080 --> 00:09:43,874
If Massospondylus
unable to compete,

58
00:09:44,375 --> 00:09:46,252
he will stay behind.

59
00:09:54,427 --> 00:09:57,722
While sauropods are on the rise…

60
00:10:01,183 --> 00:10:05,646
another legend in the making
waits for its own turn.

61
00:10:15,865 --> 00:10:21,120
Caves like these
are full of strange creatures…

62
00:10:24,373 --> 00:10:30,212
and one of them will give rise
to some of the largest dinosaurs

63
00:10:30,713 --> 00:10:32,381
of History.

64
00:10:51,525 --> 00:10:55,321
The small heterodontosaurus.

65
00:11:09,669 --> 00:11:14,548
What makes you special
It's not easy to notice right away.

66
00:11:21,597 --> 00:11:23,933
But one thing is clear.

67
00:11:27,478 --> 00:11:30,439
He doesn't shy away from a challenge.

68
00:11:38,906 --> 00:11:42,576
Even more so when food is at stake.

69
00:11:49,041 --> 00:11:52,670
Everything revolves around food.

70
00:12:03,848 --> 00:12:06,517
He can weigh the same as a chihuahua…

71
00:12:09,186 --> 00:12:11,605
but he has a superpower.

72
00:12:13,107 --> 00:12:16,610
Incredibly strong beak and jaws

73
00:12:16,694 --> 00:12:20,948
that allow him to devour
practically anything.

74
00:12:26,537 --> 00:12:27,955
And it's not just that.

75
00:12:29,540 --> 00:12:32,251
He also has bags on his cheeks,

76
00:12:32,334 --> 00:12:36,422
where you store food to eat later,
safely.

77
00:13:05,701 --> 00:13:09,747
This multifunctional mouth
will allow descendants

78
00:13:10,331 --> 00:13:15,336
become some of the biggest dinosaurs
of all time.

79
00:13:18,798 --> 00:13:21,842
Descendants like the mighty Stegosaurus

80
00:13:22,343 --> 00:13:24,845
and even triceratops.

81
00:13:26,972 --> 00:13:32,186
Small beginnings can, yes,
create great things.

82
00:13:45,699 --> 00:13:49,787
But the dinosaurs will need
of more than cheek bags

83
00:13:49,870 --> 00:13:51,497
to conquer the planet.

84
00:13:54,583 --> 00:13:57,586
On the north side of the Great Break,

85
00:13:58,379 --> 00:14:00,631
there is another new continent:

86
00:14:01,966 --> 00:14:03,008
Laurasia.

87
00:14:32,329 --> 00:14:34,290
Hidden in these waters,

88
00:14:34,957 --> 00:14:38,210
are the remnants
of a once great empire.

89
00:14:50,723 --> 00:14:51,974
The reptiles.

90
00:15:00,941 --> 00:15:05,279
They are a lethal threat
in these murky waters.

91
00:15:07,615 --> 00:15:10,159
But they also need to be careful…

92
00:15:15,414 --> 00:15:19,627
because they no longer dominate
the Jurassic swamps.

93
00:15:28,218 --> 00:15:29,929
They were usurped

94
00:15:31,430 --> 00:15:35,976
by those who hunted
on the shores of Pangea.

95
00:15:40,773 --> 00:15:42,274
The dinosaurs.

96
00:15:47,613 --> 00:15:49,198
Dilophosaurus.

97
00:15:53,202 --> 00:15:55,621
With more than 60 serrated teeth,

98
00:15:57,456 --> 00:16:00,542
she is twice the size
of a polar bear.

99
00:16:10,135 --> 00:16:13,472
And she's a hunter with relentless focus.

100
00:16:29,196 --> 00:16:32,074
But, in these flooded forests…

101
00:16:36,412 --> 00:16:41,417
there are creatures
even scarier than her.

102
00:17:20,789 --> 00:17:25,711
Like a moth attracted to light,
she follows the mysterious calls.

103
00:18:02,122 --> 00:18:04,541
A male dilophosaurus.

104
00:18:08,962 --> 00:18:12,299
Bigger and more lethal than her.

105
00:18:25,187 --> 00:18:27,648
He drew her here for a reason.

106
00:18:36,782 --> 00:18:38,951
But it's not bloodlust,

107
00:18:40,119 --> 00:18:43,831
It's pure physical attraction.

108
00:18:45,874 --> 00:18:47,501
A mating ritual.

109
00:18:50,045 --> 00:18:53,257
Scratch the floor
It's a show of strength.

110
00:18:56,927 --> 00:18:59,596
And, to display virility,

111
00:19:00,264 --> 00:19:04,226
just look at his bright red crest.

112
00:19:17,614 --> 00:19:18,615
Finally,

113
00:19:19,491 --> 00:19:21,201
it closes with a flourish.

114
00:19:23,996 --> 00:19:28,667
The song of the swamp king.

115
00:19:46,602 --> 00:19:51,148
For a fierce predator,
he is surprisingly talented.

116
00:19:57,988 --> 00:20:02,868
But the future of the lineage
It depends on her choice.

117
00:20:03,744 --> 00:20:05,621
And he just

118
00:20:06,455 --> 00:20:08,415
He's not talented enough.

119
00:20:16,882 --> 00:20:21,595
Ensure the continuity of the species
is essential.

120
00:20:23,597 --> 00:20:25,307
But, far below,

121
00:20:25,390 --> 00:20:31,104
the Earth itself threatens their existence.

122
00:20:47,537 --> 00:20:48,705
This time…

123
00:20:50,832 --> 00:20:52,834
comes from the Jurassic seas.

124
00:21:03,220 --> 00:21:05,222
A strange world…

125
00:21:08,725 --> 00:21:11,019
full of bizarre creatures.

126
00:21:24,032 --> 00:21:26,326
The most dangerous of all…

127
00:21:29,037 --> 00:21:30,664
are pliosaurs.

128
00:21:34,960 --> 00:21:38,755
The great sea monsters
that dominate the oceans.

129
00:21:41,633 --> 00:21:44,136
They are one of the reasons

130
00:21:44,219 --> 00:21:47,848
why dinosaurs
have not yet crossed that border.

131
00:21:51,184 --> 00:21:53,770
But the real threat to dinosaurs

132
00:21:55,022 --> 00:21:56,523
It's down there.

133
00:22:03,613 --> 00:22:04,865
Methane.

134
00:22:15,625 --> 00:22:17,711
This greenhouse gas

135
00:22:17,794 --> 00:22:21,757
was frozen under the seabed
for millions of years.

136
00:22:24,092 --> 00:22:28,388
But ocean warming
makes him escape

137
00:22:29,514 --> 00:22:34,644
with a devastating effect
across the planet.

138
00:22:42,819 --> 00:22:45,655
Extreme heat.

139
00:22:50,202 --> 00:22:54,498
The infinite forests
where the Massospondylus roamed

140
00:22:54,581 --> 00:22:57,542
have become an arid desert.

141
00:23:08,470 --> 00:23:14,142
The plants he fed on
practically disappeared.

142
00:23:19,648 --> 00:23:23,026
Many of their own kind
they died of hunger.

143
00:23:25,362 --> 00:23:31,535
And rising temperatures transformed
his home in a powder keg.

144
00:24:25,797 --> 00:24:28,467
It's the final blow

145
00:24:29,926 --> 00:24:31,803
for Massospondylus.

146
00:24:38,685 --> 00:24:44,774
Their 17 million years of existence
come to a tragic end.

147
00:25:06,713 --> 00:25:08,715
183 MILLION YEARS AGO

148
00:25:08,798 --> 00:25:13,553
Over time, other dinosaurs
will emerge to take their place.

149
00:25:20,435 --> 00:25:26,608
During this period, the two continents
from Earth will move further away,

150
00:25:28,318 --> 00:25:30,695
creating a fragmented world,

151
00:25:31,821 --> 00:25:36,201
with new lands
for the dinosaurs to conquer.

152
00:25:42,624 --> 00:25:46,336
160 MILLION YEARS AGO

153
00:25:57,305 --> 00:26:02,602
More than 20 million years have passed
since the extinction of Massospondylus.

154
00:26:03,436 --> 00:26:08,066
And, here, in the mountains
of what China will one day be,

155
00:26:08,650 --> 00:26:10,485
the climate cooled.

156
00:26:13,238 --> 00:26:15,282
Life prospers again.

157
00:26:23,999 --> 00:26:27,210
And a revolution is happening.

158
00:26:45,228 --> 00:26:49,024
In these cold forests at dawn,

159
00:26:50,150 --> 00:26:53,111
they have been gaining ground.

160
00:27:07,417 --> 00:27:09,002
Sauropods.

161
00:27:12,547 --> 00:27:15,300
The big four-legged dinosaurs.

162
00:27:26,436 --> 00:27:28,229
Mamenchisaurus.

163
00:27:29,272 --> 00:27:31,900
A giant from the Jurassic Period.

164
00:27:51,878 --> 00:27:56,466
Almost 40 million years
after the ancestor, Vulcanodon,

165
00:27:56,549 --> 00:27:59,135
start a great rise,

166
00:28:00,553 --> 00:28:04,391
Mamenchisaurus is now so gigantic

167
00:28:04,891 --> 00:28:08,561
that just get up
It's already a colossal task.

168
00:28:54,774 --> 00:28:59,446
They have longer necks
than any animal in history,

169
00:29:00,029 --> 00:29:04,868
that can reach the height
of a five-story building.

170
00:29:09,914 --> 00:29:13,710
And they're not the only giants
living in this forest.

171
00:29:15,086 --> 00:29:18,590
Trees too
grow higher and higher,

172
00:29:19,215 --> 00:29:24,304
so as not to be completely devoured
by these immense beasts.

173
00:29:30,018 --> 00:29:32,854
But there is a price for being so high.

174
00:29:35,690 --> 00:29:41,571
A 15m neck
can only support a small head…

175
00:29:47,368 --> 00:29:49,162
that houses a brain

176
00:29:50,038 --> 00:29:51,706
smaller than an apple.

177
00:30:11,017 --> 00:30:15,021
The evolutionary focus on size
instead of intelligence

178
00:30:15,522 --> 00:30:20,276
will help sauropods
to become the dominant herbivores

179
00:30:20,360 --> 00:30:22,320
from the Jurassic Period.

180
00:30:34,499 --> 00:30:37,669
But they're not the only ones in this forest

181
00:30:37,752 --> 00:30:39,963
who have conquered their own space.

182
00:30:50,849 --> 00:30:52,392
Anchiornis.

183
00:30:54,477 --> 00:30:57,814
Yes, he looks a little similar
with a chicken.

184
00:30:59,065 --> 00:31:01,818
And it's more or less the same size.

185
00:31:03,444 --> 00:31:05,363
But still,

186
00:31:06,614 --> 00:31:07,699
It's a dinosaur.

187
00:31:10,869 --> 00:31:13,246
A dinosaur with feathers

188
00:31:15,123 --> 00:31:19,210
and newly evolved wings.

189
00:31:38,855 --> 00:31:40,273
Sinraptor.

190
00:31:44,652 --> 00:31:46,487
Another dinosaur.

191
00:31:49,407 --> 00:31:52,744
And he's willing to hunt
this little cousin.

192
00:32:10,637 --> 00:32:15,058
His primitive wings
They are of no use on the ground.

193
00:32:35,203 --> 00:32:39,082
But that doesn't mean
let him just stay on the floor.

194
00:33:13,324 --> 00:33:17,495
Up here,
the wings become useful.

195
00:33:32,385 --> 00:33:38,558
He is one of the first dinosaurs
to be able to glide.

196
00:33:44,689 --> 00:33:49,986
With so much skill
that even catches food in the air.

197
00:33:55,658 --> 00:34:01,164
The flight will become
one of the greatest advances of dinosaurs.

198
00:34:11,799 --> 00:34:16,220
But Anchiornis
you are still just a beginner at this.

199
00:34:23,478 --> 00:34:25,229
For now,

200
00:34:27,190 --> 00:34:29,025
this airspace…

201
00:34:32,278 --> 00:34:34,530
belongs to pterosaurs.

202
00:34:41,579 --> 00:34:46,209
Flying dinosaurs
are at a disadvantage in the skies,

203
00:34:46,292 --> 00:34:47,335
for now.

204
00:34:51,839 --> 00:34:53,466
But, over time,

205
00:34:54,175 --> 00:34:58,429
pterosaurs will have a worthy rival.

206
00:35:04,393 --> 00:35:07,522
The planet continues to evolve,

207
00:35:08,272 --> 00:35:10,525
just like dinosaurs.

208
00:35:15,571 --> 00:35:19,367
And as the end
the Jurassic Period approaches…

209
00:35:21,744 --> 00:35:25,748
their dominion over the earth
on both continents

210
00:35:26,290 --> 00:35:28,543
gets stronger and stronger.

211
00:35:33,422 --> 00:35:36,843
153 MILLION YEARS AGO

212
00:35:36,926 --> 00:35:40,805
Seven million years ago
since Anchiornis took flight.

213
00:35:48,020 --> 00:35:52,066
Here, where North America will one day be…

214
00:35:56,863 --> 00:36:00,449
geothermal heat boils at the surface.

215
00:36:02,285 --> 00:36:06,372
An echo of past extinctions.

216
00:36:14,797 --> 00:36:18,843
The sauropods here
are bigger than ever.

217
00:36:22,471 --> 00:36:27,351
The bigger is better strategy
it's working.

218
00:36:32,148 --> 00:36:38,529
But these other dinosaurs evolve
through a completely different path.

219
00:36:42,783 --> 00:36:44,202
Stegosaurs.

220
00:36:49,832 --> 00:36:54,253
Very different from the small ancestors
with bags on the cheeks.

221
00:36:58,424 --> 00:37:01,219
Now they are so heavy
as elephants,

222
00:37:01,886 --> 00:37:07,558
equipped with armor,
camouflage and weapons.

223
00:37:09,810 --> 00:37:12,146
Here, at the end of the Jurassic Period,

224
00:37:12,730 --> 00:37:14,774
they need this protection.

225
00:37:30,081 --> 00:37:33,918
Because there is danger
in these dark forests.

226
00:37:42,260 --> 00:37:43,928
Allosaurus.

227
00:37:48,391 --> 00:37:52,228
8m long
and teeth as sharp as daggers,

228
00:37:52,311 --> 00:37:56,274
they are the most successful predators
of the time itself.

229
00:38:02,738 --> 00:38:05,616
But this young male is not hunting.

230
00:38:08,286 --> 00:38:09,704
He wants to steal.

231
00:38:17,003 --> 00:38:18,170
From a female.

232
00:38:22,800 --> 00:38:24,468
Of the same species,

233
00:38:24,969 --> 00:38:29,682
but bigger, stronger
and with several scars.

234
00:39:11,974 --> 00:39:15,686
The young male was lucky
of not having been killed by her.

235
00:40:00,398 --> 00:40:02,733
The storms have passed.

236
00:40:05,945 --> 00:40:08,864
The young male hasn't eaten in weeks.

237
00:40:16,580 --> 00:40:20,960
He has no choice
except to try your luck with a herd

238
00:40:21,669 --> 00:40:23,337
of stegosaurs.

239
00:40:33,722 --> 00:40:37,435
But he can't hide
when it's out in the open...

240
00:40:39,687 --> 00:40:44,066
and that gives the herd time
to prepare defenses.

241
00:40:48,988 --> 00:40:53,200
They form a wall
of moving bodies and spines.

242
00:40:58,998 --> 00:41:00,332
It's intimidating...

243
00:41:02,918 --> 00:41:05,880
and confuses the young Allosaurus.

244
00:41:07,465 --> 00:41:10,217
He can't choose which one to attack.

245
00:41:21,979 --> 00:41:23,939
But new problems arise.

246
00:41:27,193 --> 00:41:30,237
The female veteran has just entered the game.

247
00:41:32,781 --> 00:41:35,159
And she plays this game

248
00:41:35,659 --> 00:41:39,413
much longer than him.

249
00:41:44,919 --> 00:41:47,630
She manages to isolate one of the herd.

250
00:41:53,385 --> 00:41:57,890
But the stegosaurus
developed a perfect weapon.

251
00:41:59,141 --> 00:42:02,561
A club-shaped tail
with 1m thorns

252
00:42:03,771 --> 00:42:06,774
called tagomizer.

253
00:43:04,164 --> 00:43:06,834
For the female, the game is over.

254
00:43:13,424 --> 00:43:16,302
For the young male, it is time for revenge.

255
00:43:19,305 --> 00:43:20,973
And lunch.

256
00:43:22,600 --> 00:43:26,854
Because allosaurs are cannibals.

257
00:43:37,906 --> 00:43:41,910
Fifty million years
after surviving an apocalypse,

258
00:43:43,162 --> 00:43:48,876
the dominance of dinosaurs on Earth
now it is absolute.

259
00:43:59,887 --> 00:44:02,222
But the world as they know it

260
00:44:02,765 --> 00:44:04,183
is changing.

261
00:44:10,230 --> 00:44:13,359
Temperatures are dropping
across the globe…

262
00:44:19,281 --> 00:44:23,911
bringing snow to the northern regions of the planet.

263
00:44:26,997 --> 00:44:31,710
Something that few dinosaurs
have already experienced.

264
00:44:38,842 --> 00:44:41,136
From these frozen lands,

265
00:44:41,637 --> 00:44:43,681
a new type of dinosaur

266
00:44:44,348 --> 00:44:45,724
will emerge.

267
00:44:54,233 --> 00:44:57,778
The tyrannosaurs are coming.

268
00:46:50,766 --> 00:46:55,771
