1
00:00:09,134 --> 00:00:15,181
（7500万年前）

2
00:00:15,682 --> 00:00:17,767
在浩瀚太空的深处

3
00:00:18,727 --> 00:00:20,603
威胁正在悄然逼近

4
00:00:22,647 --> 00:00:26,526
被困在木星与火星轨道之间的…

5
00:00:28,778 --> 00:00:30,947
是一条小行星带

6
00:00:33,324 --> 00:00:37,454
150万块远古岩石的碎片

7
00:00:38,329 --> 00:00:40,206
环绕着太阳

8
00:00:43,626 --> 00:00:46,129
无止尽地漂流

9
00:00:55,680 --> 00:00:59,768
但在某个纯属偶然的瞬间…

10
00:01:04,731 --> 00:01:08,943
一颗小行星被抛出了原本的轨道

11
00:01:11,029 --> 00:01:12,864
一刹那间

12
00:01:13,615 --> 00:01:16,451
远在地球数百万公里之外

13
00:01:17,077 --> 00:01:19,913
它便踏上了一条新的轨道

14
00:01:20,830 --> 00:01:25,001
直奔我们太阳系的中心

15
00:01:35,553 --> 00:01:40,433
但它的旅程
将以一场突如其来的灾难告终

16
00:01:42,268 --> 00:01:48,066
这亦是地球历史上最惨烈的浩劫之一

17
00:01:51,277 --> 00:01:53,154
恐龙的史诗

18
00:01:54,405 --> 00:01:56,282
也在此刻

19
00:01:57,492 --> 00:01:59,536
迎来了终章

20
00:02:56,217 --> 00:03:00,722
《恐龙时代：你不知道的故事》

21
00:03:06,728 --> 00:03:13,610
第四章：陨落

22
00:03:15,486 --> 00:03:17,739
（7200万年前）

23
00:03:17,822 --> 00:03:22,035
（7200万年前 白垩纪晚期）

24
00:03:23,661 --> 00:03:25,246
距这颗小行星

25
00:03:25,330 --> 00:03:29,042
启程飞向地球已有三百万年

26
00:03:31,169 --> 00:03:34,631
与此同时 恐龙依旧统治着这颗星球

27
00:03:35,715 --> 00:03:41,512
它们称霸了陆地
如今更是向海洋进发

28
00:03:44,599 --> 00:03:49,979
高涨的海平面将北美大陆一分为二

29
00:03:54,609 --> 00:03:56,653
形成了绵延不绝的海岸线…

30
00:04:00,573 --> 00:04:03,534
数百座热带岛屿…

31
00:04:05,828 --> 00:04:08,039
以及无尽的机遇

32
00:04:20,551 --> 00:04:23,304
但这些岛屿绝非天堂

33
00:04:27,016 --> 00:04:30,019
这里栖息着令人胆寒的掠食者

34
00:04:34,983 --> 00:04:40,571
同类中速度最快
身手最敏捷的恐龙之一

35
00:04:44,075 --> 00:04:48,538
堪称北美版的棘龙

36
00:04:59,716 --> 00:05:03,303
只是它的模样绝非你想象的那样

37
00:05:04,512 --> 00:05:06,681
甚至可以说是天差地别

38
00:05:09,183 --> 00:05:11,853
这就是黄昏鸟

39
00:05:13,396 --> 00:05:18,443
它的确高大威猛 速度敏捷

40
00:05:20,570 --> 00:05:26,284
但它与那些庞大可怖的近亲
简直有着天壤之别

41
00:05:36,294 --> 00:05:37,628
它滑稽可笑

42
00:05:38,338 --> 00:05:39,922
又笨手笨脚

43
00:05:42,050 --> 00:05:44,010
牙齿也十分细小

44
00:05:44,802 --> 00:05:48,431
与凶猛猎手的形象相去甚远

45
00:05:50,183 --> 00:05:53,519
但它与棘龙有一个共同特点

46
00:05:54,187 --> 00:05:57,732
它不受陆地的束缚

47
00:06:05,281 --> 00:06:10,995
事实上 它是有史以来
进化最完善的水生恐龙

48
00:06:18,294 --> 00:06:21,422
就像某种史前企鹅

49
00:06:22,465 --> 00:06:27,804
它能够游到遥远的海域
抵达其他生物

50
00:06:28,429 --> 00:06:31,849
无法企及的觅食区

51
00:06:51,953 --> 00:06:56,541
它得到了这片蔚蓝新世界的馈赠

52
00:07:05,967 --> 00:07:11,305
在水下 它那笨拙的大脚
化作强劲的推进器

53
00:07:15,309 --> 00:07:21,315
94颗针尖般锋利的牙齿
能够轻松捕获小鱼

54
00:07:38,583 --> 00:07:40,376
但作为需要呼吸空气的生物

55
00:07:41,294 --> 00:07:44,213
它仍然受制于水面

56
00:07:56,350 --> 00:08:00,813
但水面可不是个安全的地方

57
00:08:04,275 --> 00:08:05,610
因为在更深处

58
00:08:06,944 --> 00:08:09,155
潜伏着

59
00:08:09,822 --> 00:08:13,159
体型是虎鲸两倍的巨兽

60
00:08:20,500 --> 00:08:22,502
沧龙

61
00:08:29,342 --> 00:08:33,429
它们是这片海域的顶级掠食者

62
00:08:41,771 --> 00:08:45,399
黄昏鸟必须赶紧回到岸边

63
00:08:50,530 --> 00:08:54,033
然而沧龙的游速快得惊人

64
00:08:57,036 --> 00:09:01,582
幸运的是 黄昏鸟的身手更为敏捷

65
00:09:08,297 --> 00:09:09,840
但它已经筋疲力尽了

66
00:09:13,219 --> 00:09:18,224
这给了沧龙予以最后一击的机会

67
00:09:36,492 --> 00:09:39,954
黄昏鸟是真正的幸存者

68
00:09:41,122 --> 00:09:46,877
它对海洋的探索远超任何恐龙

69
00:09:49,589 --> 00:09:55,052
但就算对最擅长游泳的恐龙而言
这片海域依旧是险象环生

70
00:10:03,311 --> 00:10:07,106
尽管恐龙在浅滩颇有建树

71
00:10:07,690 --> 00:10:09,734
沧龙

72
00:10:09,817 --> 00:10:11,736
才是波涛之上的霸主

73
00:10:19,910 --> 00:10:23,831
1300公里以北的陆地上

74
00:10:24,332 --> 00:10:26,250
情况截然不同

75
00:10:38,095 --> 00:10:41,641
得益于温暖而稳定的气候

76
00:10:41,724 --> 00:10:46,145
恐龙在这里的统治无可撼动

77
00:10:53,944 --> 00:10:58,699
自侏罗纪伊始 蜥脚类恐龙

78
00:10:58,783 --> 00:11:02,453
就在参天古树间繁衍生息

79
00:11:08,626 --> 00:11:12,380
但在它们脚下
一场革命正在悄然发生

80
00:11:18,969 --> 00:11:22,306
一头雌性鸭嘴龙

81
00:11:25,434 --> 00:11:29,605
尽管在这些巨兽面前显得极为娇小

82
00:11:29,689 --> 00:11:33,526
它的体型其实要比大象更为庞大

83
00:11:34,568 --> 00:11:38,155
这些庞然大物无法阻挡它的脚步

84
00:11:39,532 --> 00:11:43,452
因为没有什么
能阻挡一位肩负使命的母亲

85
00:11:45,871 --> 00:11:47,707
它的使命

86
00:11:48,207 --> 00:11:50,751
就是养家糊口

87
00:11:52,920 --> 00:11:54,588
而它的家人

88
00:11:56,132 --> 00:11:57,466
就在山下

89
00:12:07,893 --> 00:12:14,108
很久以前 它们颊囊里
塞满了食物的祖先稀少而分散

90
00:12:16,986 --> 00:12:23,701
但如今鸭嘴龙子孙满堂
动辄数千头成群结队

91
00:12:26,245 --> 00:12:31,751
它们成就了地球上有史以来
规模最为宏大的恐龙集会

92
00:12:34,128 --> 00:12:38,549
但这头雌性鸭嘴龙的家族
并未跟随大群迁徙

93
00:12:40,342 --> 00:12:43,637
在托儿所的安全庇护下

94
00:12:44,138 --> 00:12:48,976
数百只年幼的鸭嘴龙
身处一片庞大的育婴空间…

95
00:12:51,187 --> 00:12:54,315
其中就包括这只雌性自己的孩子

96
00:12:58,986 --> 00:13:03,699
六个月大的幼崽胃口极佳

97
00:13:04,492 --> 00:13:08,412
几乎能吞下妈妈带来的任何东西

98
00:13:11,457 --> 00:13:12,708
什么都吃得下

99
00:13:24,929 --> 00:13:29,475
这种鸟类般的喂养方式需要频繁补给

100
00:13:30,142 --> 00:13:35,022
因此 雌性要不断外出觅食

101
00:13:36,816 --> 00:13:39,193
妈妈不在的时候

102
00:13:39,276 --> 00:13:42,196
小家伙们便开始嬉戏玩耍

103
00:14:06,053 --> 00:14:08,931
翼龙的体型如今空前巨大

104
00:14:09,473 --> 00:14:13,310
其翼展堪比战斗机

105
00:14:15,938 --> 00:14:19,567
鸭嘴龙的托儿所成了绝佳的狩猎场

106
00:14:20,067 --> 00:14:24,405
毫无防备的巢穴最容易下手

107
00:14:44,216 --> 00:14:46,886
尽管面对这头庞然巨物的威胁

108
00:14:46,969 --> 00:14:50,848
母亲仍然会
不惜一切代价保护自己的幼崽

109
00:15:07,781 --> 00:15:13,412
但巨型翼龙决心要饱餐一顿

110
00:15:20,044 --> 00:15:25,090
巢穴里传来的尖叫声
犹如给捕食者摇响了晚餐铃

111
00:15:41,190 --> 00:15:44,485
但小家伙们的哭号不仅是出于恐惧

112
00:15:45,611 --> 00:15:47,905
它们也是在呼唤救援

113
00:16:07,216 --> 00:16:11,136
这种保护后代的强烈本能

114
00:16:12,179 --> 00:16:17,017
正是鸭嘴龙取得非凡成功的关键

115
00:16:19,144 --> 00:16:24,692
但其他恐龙的防御能力
也发展到了全新的高度

116
00:16:26,151 --> 00:16:31,490
因为捕食者与猎物之间的
较量正愈演愈烈

117
00:16:33,993 --> 00:16:39,748
这也催生了
有史以来最有代表性的恐龙

118
00:16:45,879 --> 00:16:48,132
这一过程如此漫长

119
00:16:48,632 --> 00:16:52,803
以至于北美大陆都发生了漂移

120
00:16:54,013 --> 00:16:57,433
陆地隆起 直冲云霄

121
00:17:06,900 --> 00:17:09,028
形成了落基山脉

122
00:17:11,488 --> 00:17:15,034
就在这山脚下

123
00:17:16,744 --> 00:17:20,497
恐龙鏖战正酣

124
00:17:28,797 --> 00:17:30,883
厚头龙

125
00:17:32,384 --> 00:17:35,804
正在用它们厚得离谱的头骨

126
00:17:38,640 --> 00:17:41,602
争夺霸主之位

127
00:17:47,024 --> 00:17:48,776
在它们旁边

128
00:17:49,985 --> 00:17:53,906
是一种头饰更显威仪的恐龙

129
00:18:00,120 --> 00:18:02,122
三角龙

130
00:18:10,631 --> 00:18:13,092
它看上去很像犀牛

131
00:18:13,926 --> 00:18:16,637
但体型是犀牛的两倍

132
00:18:20,057 --> 00:18:25,104
头顶的矛状犄角长逾一米

133
00:18:32,778 --> 00:18:38,283
三角龙和厚头龙的武装都相当惊人

134
00:18:40,661 --> 00:18:43,205
然而在这里

135
00:18:43,288 --> 00:18:47,126
有些生物的武装
更为精良 也更为危险

136
00:18:58,303 --> 00:19:00,639
在夜幕的掩护下

137
00:19:01,223 --> 00:19:04,893
最强大、最精锐的装甲战士现身了

138
00:19:07,437 --> 00:19:11,775
它身长六米 极具领地意识

139
00:19:15,070 --> 00:19:18,782
大腹甲龙

140
00:19:27,082 --> 00:19:29,626
它正在巡逻

141
00:19:31,461 --> 00:19:32,796
防范

142
00:19:33,297 --> 00:19:35,174
胆敢闯入领地的入侵者

143
00:19:43,265 --> 00:19:48,812
他那坦克般的身躯
覆盖着数十块厚重的骨板

144
00:19:55,235 --> 00:19:56,862
更厉害的是

145
00:19:57,696 --> 00:20:00,532
它还有一件威力强大的新武器

146
00:20:05,037 --> 00:20:08,957
一条重达半吨的棍棒状尾巴

147
00:20:09,750 --> 00:20:14,338
足以应对潜伏在森林中的任何威胁

148
00:20:20,469 --> 00:20:22,221
他感觉到了什么

149
00:20:52,000 --> 00:20:54,253
它的领地…

150
00:20:56,463 --> 00:20:59,716
已被最可怕的入侵者突破

151
00:21:12,604 --> 00:21:14,940
一头霸王龙

152
00:22:39,483 --> 00:22:41,443
甲龙

153
00:22:42,402 --> 00:22:43,653
对阵霸王龙

154
00:22:53,246 --> 00:22:55,874
一场历经数百万年

155
00:22:56,875 --> 00:22:59,378
而形成的进化僵局

156
00:23:20,232 --> 00:23:22,234
但在这场军备竞赛中

157
00:23:24,069 --> 00:23:28,198
有一样东西
的确能让这些恐龙脱颖而出

158
00:23:31,410 --> 00:23:33,161
智力

159
00:24:15,078 --> 00:24:20,834
霸王龙是有史以来
最凶残的掠食者之一

160
00:24:23,211 --> 00:24:26,256
为了维持其巅峰状态

161
00:24:27,466 --> 00:24:33,138
它必须每天摄入
相当于200块牛排的猎物

162
00:24:35,307 --> 00:24:40,562
然而 迄今为止 它还一口都没吃

163
00:24:43,565 --> 00:24:48,945
因为它对这份外卖另有打算

164
00:24:54,326 --> 00:24:58,955
但甲龙可不是什么小点心

165
00:25:05,712 --> 00:25:08,423
六吨的肌肉和骨头

166
00:25:08,924 --> 00:25:13,178
布满各种突起和疙瘩

167
00:25:25,398 --> 00:25:27,359
即便是霸王龙

168
00:25:28,109 --> 00:25:29,986
也相当吃力

169
00:26:04,312 --> 00:26:05,564
终于

170
00:26:06,690 --> 00:26:08,567
它的旅途结束了

171
00:26:17,659 --> 00:26:22,122
它如此费尽心思的原因

172
00:26:35,176 --> 00:26:37,887
就是这五只饥肠辘辘的幼崽

173
00:26:51,610 --> 00:26:53,445
它是凶残的杀手

174
00:26:54,112 --> 00:26:55,238
没错

175
00:26:56,364 --> 00:26:57,824
但同时

176
00:26:58,366 --> 00:27:00,076
它也是慈爱的母亲

177
00:27:16,468 --> 00:27:18,219
它要确保

178
00:27:19,304 --> 00:27:21,723
它的孩子们吃饱喝足

179
00:27:25,644 --> 00:27:29,564
给它们的一生开个好头

180
00:27:34,235 --> 00:27:36,905
这正是它们远古的祖先

181
00:27:37,405 --> 00:27:39,324
所梦寐以求的

182
00:27:42,661 --> 00:27:48,667
远在三叠纪 小小的马拉鳄龙
刚破壳而出就已堕入地狱

183
00:27:50,168 --> 00:27:53,046
这些尚未成形的恐龙

184
00:27:54,172 --> 00:27:56,925
被迫栖身于阴影之中

185
00:27:57,759 --> 00:28:01,596
躲避横行霸道的爬行动物

186
00:28:03,890 --> 00:28:06,184
但它们得到了命运之神的眷顾…

187
00:28:08,311 --> 00:28:10,105
化灾难

188
00:28:11,523 --> 00:28:13,817
为机遇…

189
00:28:16,403 --> 00:28:19,197
开启了它们史诗般的崛起

190
00:28:22,659 --> 00:28:27,539
它们变得越来越大
越来越强 越来越可怕

191
00:28:34,212 --> 00:28:35,463
终有一天

192
00:28:36,840 --> 00:28:40,135
它们不仅征服了陆地

193
00:28:41,636 --> 00:28:42,721
也主宰了海洋

194
00:28:44,472 --> 00:28:45,974
与天空

195
00:28:47,976 --> 00:28:51,020
历经了1.6亿年

196
00:28:52,605 --> 00:28:55,316
恐龙如今已称王称霸

197
00:28:56,818 --> 00:29:00,321
世间万物都无法与之抗衡

198
00:29:06,828 --> 00:29:09,539
但来自天外的力量即将终结

199
00:29:10,123 --> 00:29:11,332
它们的霸权

200
00:29:13,209 --> 00:29:17,922
因为这个家族的旅程才刚刚开始

201
00:29:19,215 --> 00:29:20,675
另一段旅程

202
00:29:21,176 --> 00:29:23,344
却已步入终章

203
00:29:27,932 --> 00:29:34,522
这颗小行星如今正以
相当于音速50倍的速度直扑地球

204
00:29:36,024 --> 00:29:40,028
它终将迎来自己的宿命

205
00:30:13,561 --> 00:30:18,483
它以相当于十亿颗原子弹的威力

206
00:30:19,234 --> 00:30:23,613
撞向墨西哥海岸附近海域

207
00:30:24,823 --> 00:30:27,951
爆炸的高温足以让海洋蒸发见底

208
00:30:30,995 --> 00:30:35,667
方圆数百公里内
所有生物亦都化为乌有

209
00:30:44,676 --> 00:30:48,096
远在落基山脉脚下

210
00:30:49,055 --> 00:30:55,144
这些庞然大物全然不知灾难即将降临

211
00:31:17,125 --> 00:31:20,795
史上最强烈的地震正在发生

212
00:31:29,596 --> 00:31:32,307
然而 这还不是最可怕的

213
00:31:35,602 --> 00:31:41,065
一道由炽热尘埃组成的巨浪席卷而来

214
00:31:58,499 --> 00:32:03,254
无数恐龙被困于这团死亡之云之下

215
00:32:03,338 --> 00:32:05,465
就此长眠

216
00:32:08,051 --> 00:32:13,222
它们的世界炙热难耐 燃起熊熊大火

217
00:32:22,357 --> 00:32:24,442
就算是最坚固的盔甲

218
00:32:24,943 --> 00:32:26,778
也无济于事

219
00:32:36,162 --> 00:32:39,749
浓烟迅速吞没了整颗星球

220
00:32:40,249 --> 00:32:42,418
灰烬弥漫 令地球难以呼吸

221
00:32:44,504 --> 00:32:46,923
黑暗笼罩了大地

222
00:33:32,844 --> 00:33:37,890
少数坚守到日暮时分的幸存者

223
00:33:39,642 --> 00:33:41,602
坠入了梦魇

224
00:33:43,104 --> 00:33:46,399
在黑暗中苟延残喘

225
00:34:12,675 --> 00:34:14,218
夜幕降临

226
00:34:14,886 --> 00:34:20,475
死去的恐龙已不计其数

227
00:34:47,668 --> 00:34:50,338
由于缺乏阳光的照射

228
00:34:50,838 --> 00:34:54,759
地球陷入了撞击寒冬

229
00:35:01,140 --> 00:35:05,937
全球气温骤降25摄氏度

230
00:35:09,148 --> 00:35:15,363
几乎所有恐龙都难以承受这般严寒

231
00:35:27,041 --> 00:35:29,460
巨型蜥脚类恐龙

232
00:35:29,961 --> 00:35:31,671
长眠于参天巨木化作的灰烬之中

233
00:35:32,171 --> 00:35:37,677
正是这些大树
赋予了它们如此高大的身躯

234
00:35:53,484 --> 00:35:55,778
在它们的聚集地

235
00:35:56,529 --> 00:35:58,614
恐龙族群同生

236
00:35:59,407 --> 00:36:00,950
亦共死

237
00:36:08,708 --> 00:36:12,295
纵使有母亲尽责的守护

238
00:36:12,378 --> 00:36:14,505
幼崽也难逃酷寒的侵袭

239
00:36:20,636 --> 00:36:24,765
酷寒肆虐

240
00:36:25,391 --> 00:36:28,728
就算是最著名的恐龙也未能幸免

241
00:36:37,528 --> 00:36:39,530
暴君之王

242
00:36:40,448 --> 00:36:41,866
已然陨落

243
00:37:01,802 --> 00:37:05,223
即便是强大的霸王龙

244
00:37:05,848 --> 00:37:08,351
也无法在这场灾难中幸存

245
00:37:40,007 --> 00:37:42,551
恐龙的统治

246
00:37:44,095 --> 00:37:45,721
终于

247
00:37:46,514 --> 00:37:48,474
走到了尽头

248
00:38:17,003 --> 00:38:20,298
而在6600万年后

249
00:38:22,717 --> 00:38:26,262
恐龙再度崛起

250
00:38:30,891 --> 00:38:32,268
这一次

251
00:38:32,351 --> 00:38:34,270
由我们亲手将其唤醒

252
00:38:42,153 --> 00:38:47,908
如今 它们的化石如同纪念碑
诉说着一个逝去的世界

253
00:38:49,076 --> 00:38:50,453
更重要的是

254
00:38:51,787 --> 00:38:58,210
它们是解开恐龙传奇奥秘的钥匙

255
00:39:00,004 --> 00:39:04,884
我们如今对恐龙生命的认知
已达到前所未有的高度

256
00:39:06,302 --> 00:39:08,471
从它们诞生之初

257
00:39:09,638 --> 00:39:11,265
直至生命终点

258
00:39:15,019 --> 00:39:20,024
令人震惊的是
在地球最黑暗的日子里

259
00:39:20,608 --> 00:39:23,361
并非所有恐龙都灭绝了

260
00:39:25,363 --> 00:39:30,743
有些恐龙体型足够娇小
躲过了这场末日浩劫

261
00:39:33,496 --> 00:39:35,373
甚至

262
00:39:36,040 --> 00:39:38,459
存活至今

263
00:39:40,961 --> 00:39:46,384
它们就是
我们如今称为鸟类的飞行恐龙

264
00:39:50,846 --> 00:39:56,936
它们过往的痕迹就隐藏在我们眼前

265
00:40:18,416 --> 00:40:24,588
那段始于2.35亿年前的非凡旅程

266
00:40:25,798 --> 00:40:29,427
至今仍在我们身边延续

267
00:40:31,554 --> 00:40:33,722
它们是如今仅存的纽带

268
00:40:36,016 --> 00:40:38,644
连通那个早已消逝的王国

269
00:40:40,646 --> 00:40:42,231
连接着

270
00:40:43,232 --> 00:40:47,445
恐龙时代

271
00:42:45,396 --> 00:42:49,358
