== 梁氏出品 必属精品 ==

1
00:00:33,166 --> 00:00:35,293
让我们展开
时光倒流的旅程

2
00:00:36,636 --> 00:00:38,536
重返尚无人类的远古

3
00:00:41,007 --> 00:00:43,168
回到6500万年前

4
00:00:44,911 --> 00:00:48,244
一路上只见
气侯与植物经历了巨变

5
00:00:49,249 --> 00:00:53,345
陆块推挤，山脉隆起
地表也跟着移动

6
00:01:07,032 --> 00:01:10,126
现在我们来到了独特的
白垩纪时期

7
00:01:10,702 --> 00:01:13,068
地球和现在相去甚远

8
00:01:15,507 --> 00:01:16,531
没有喜马拉雅山

9
00:01:17,642 --> 00:01:19,303
大西洋仅一半宽

10
00:01:20,645 --> 00:01:23,341
没有草原
只有针叶林跟蕨类

11
00:01:26,750 --> 00:01:29,446
这时的世界是恐龙的天下

12
00:01:37,461 --> 00:01:42,398
大型爬虫类横行地表
例如暴龙就重达五吨

13
00:01:52,843 --> 00:01:56,973
“与恐龙共舞”
将为您介绍恐龙的生活

14
00:01:58,449 --> 00:02:02,010
看看它们
觅食，争斗，繁衍的情形

15
00:02:03,620 --> 00:02:05,087
同时各位也将目睹

16
00:02:05,556 --> 00:02:09,048
大自然如何让恐龙
步上灭亡之路

17
00:02:18,135 --> 00:02:22,003
但是本节目还将带您
回到更远古的时代

18
00:02:27,544 --> 00:02:32,311
重返侏罗纪时期
当时的地球生物壮观无比

19
00:02:39,223 --> 00:02:41,691
生物受温暖热带气侯笼罩

20
00:02:43,127 --> 00:02:44,685
南北极没有冰帽

21
00:02:45,829 --> 00:02:48,525
显花植物与阔叶木尚未形成

22
00:02:49,833 --> 00:02:53,599
不管是天空或地上
全是爬虫类的天下

23
00:02:54,438 --> 00:02:57,236
而其中最普遍的就是恐龙了

24
00:03:07,150 --> 00:03:09,277
但是恐龙并不是唯一的巨兽

25
00:03:10,753 --> 00:03:12,778
巨大的翼手龙称霸天空

26
00:03:14,123 --> 00:03:18,287
资源丰富的汪洋中
也孕育了大型海生爬虫类

27
00:03:26,803 --> 00:03:31,399
本集节目中将回溯亘古
探究恐龙的起源

28
00:03:37,113 --> 00:03:39,911
这是地球
在三叠纪时期的景象

29
00:03:41,517 --> 00:03:43,576
五大洲尚未分裂成形

30
00:03:44,353 --> 00:03:46,218
仅有一块所谓的
“盘古大陆”

31
00:03:47,757 --> 00:03:49,850
环境恶劣，多为沙漠

32
00:03:59,702 --> 00:04:03,570
三叠纪时期虽然出现过
许多种古爬虫类

33
00:04:05,207 --> 00:04:07,698
然而此刻这片干旱的大地上

34
00:04:08,343 --> 00:04:10,868
却出现了一种
前所未见的动物

35
00:04:11,913 --> 00:04:14,507
一群爬虫类将改变地球生态

36
00:04:15,684 --> 00:04:18,084
影响了往后的一亿六千万年

37
00:04:20,122 --> 00:04:22,613
这就是恐龙始祖

38
00:04:23,125 --> 00:04:25,184
也是恐龙故事的开端

39
00:04:37,539 --> 00:04:40,736
亚历桑纳州
西元二亿二千万年前

40
00:04:42,244 --> 00:04:46,078
盘古大陆上曙光乍现
照耀西部山丘

41
00:04:47,416 --> 00:04:52,149
某一群巨大的爬虫类
曾主宰地球五千万年

42
00:04:53,989 --> 00:04:57,652
可惜它们的全盛时期
已经成为往事

43
00:05:00,429 --> 00:05:02,124
在茂盛的蕨类原地上

44
00:05:02,698 --> 00:05:05,690
新种爬虫类
为了争夺新世界的领导权

45
00:05:06,268 --> 00:05:08,327
展开了激烈的演化战争

46
00:05:14,042 --> 00:05:18,103
在三叠纪的新生地上
恐龙虽然仍属罕见

47
00:05:18,847 --> 00:05:22,374
但是却已经显现了
未来成功的迹象

48
00:05:33,261 --> 00:05:36,196
这是雨季末期，河水充足

49
00:05:37,265 --> 00:05:41,964
但是后来绿地却消失了
连续九个月没下雨

50
00:05:46,241 --> 00:05:48,801
有一种爬虫变得相当耐旱

51
00:05:49,945 --> 00:05:53,039
虚形龙只要少量的水份
就能生存

52
00:05:54,282 --> 00:05:55,874
骨质轻，动作快

53
00:05:56,852 --> 00:05:59,082
而且它最擅长的就是…

54
00:05:59,554 --> 00:06:00,612
猎捕食物

55
00:06:19,507 --> 00:06:23,500
在更早的一千万年前
首次出现了恐龙

56
00:06:24,578 --> 00:06:26,910
那时仍是小型的掠食者

57
00:06:28,049 --> 00:06:29,516
它们具有独特的骨盆与踝节

58
00:06:31,051 --> 00:06:32,643
可以两脚平衡站立

59
00:06:33,687 --> 00:06:36,485
它们反应超快，天生是赢家

60
00:06:45,465 --> 00:06:49,424
这阵叫声表示一大群
扁兽龙就要出现了

61
00:06:50,570 --> 00:06:54,438
它们一早从蕨类原地
来到河边喝水

62
00:07:03,416 --> 00:07:08,820
令人印象深刻的扁兽龙
重达一吨，但并不是恐龙

63
00:07:09,322 --> 00:07:11,187
它们属于更古老的爬虫类

64
00:07:12,258 --> 00:07:15,489
许多种大型爬虫类
曾一度遍布大陆

65
00:07:16,029 --> 00:07:19,465
但是如今只剩下
这种扁兽龙存活

66
00:07:20,133 --> 00:07:22,863
而且也濒临绝种边缘

67
00:07:25,205 --> 00:07:28,902
扁兽龙虽然面目狰狞
却是温和的草食动物

68
00:07:30,076 --> 00:07:32,135
长牙用来挖掘植物根部

69
00:07:35,949 --> 00:07:40,409
雄性的扁兽龙对峙时
长牙可充当致命武器

70
00:07:49,262 --> 00:07:52,060
扁兽龙行动缓慢
是虚形龙的猎物

71
00:07:55,535 --> 00:07:58,663
这只母虚形龙
忙着物色老弱猎物

72
00:08:18,758 --> 00:08:23,320
虚形龙等类的恐龙后代
未来将主宰地球

73
00:08:24,164 --> 00:08:25,859
它们动作快速敏捷

74
00:08:26,566 --> 00:08:30,696
因此在三叠纪中期
才能独霸一方

75
00:08:36,342 --> 00:08:39,539
在河川下游可以见到
三叠纪的一大奇兽

76
00:08:40,413 --> 00:08:44,247
犬牙兽是介于
爬虫类与晡乳类之间

77
00:08:46,752 --> 00:08:50,279
跑动时像爬虫类一样
背脊骨会左右摇摆

78
00:08:51,056 --> 00:08:54,514
但却又像晡乳动物
有体毛，挖地穴居

79
00:09:03,002 --> 00:09:05,402
洞里的母犬牙兽就地衣而眠

80
00:09:07,239 --> 00:09:11,198
犬牙兽的配偶关系极亲密
终身为伴

81
00:09:13,545 --> 00:09:16,036
它们跟陆生爬虫一样会产卵

82
00:09:16,548 --> 00:09:19,676
但是幼兽孵化后
却完全依赖父母

83
00:09:20,519 --> 00:09:24,114
前三个月会吸食
母亲腹部乳腺的分泌物

84
00:09:26,058 --> 00:09:30,859
这种繁殖型态能保护幼兽
不受外在掠食者伤害

85
00:09:35,766 --> 00:09:38,667
公犬牙兽
白天也会在洞穴看守

86
00:09:39,303 --> 00:09:40,861
并且还会整理家+

87
00:09:42,306 --> 00:09:44,934
到了晚上，它才会出去打猎

88
00:09:55,186 --> 00:09:59,850
这一类型的爬虫类不久
便演化成有毛的小型晡乳类

89
00:10:11,802 --> 00:10:12,894
干季炎热

90
00:10:13,838 --> 00:10:16,363
扁兽龙来到灌木丛林里觅食

91
00:10:23,714 --> 00:10:25,739
和煦的微风突然转变

92
00:10:26,250 --> 00:10:28,013
空气中弥漫着恐惧

93
00:11:00,618 --> 00:11:03,178
无情杀手后鳄兽现身了

94
00:11:04,121 --> 00:11:07,113
它是当时最大的肉食动物

95
00:11:12,997 --> 00:11:14,692
扁兽龙惊慌逃窜

96
00:11:15,366 --> 00:11:18,893
由于动作太慢
一只扁兽龙遭受重创

97
00:11:20,504 --> 00:11:22,267
后鳄兽是恐龙的远亲

98
00:11:23,073 --> 00:11:25,200
与恐龙源自同一爬虫始祖

99
00:11:26,176 --> 00:11:29,111
但是后鳄兽前身过重
无法以双脚奔跑

100
00:11:30,281 --> 00:11:33,648
幸好它的速度已经够快
可以赶上兽群

101
00:11:38,222 --> 00:11:42,955
扁兽龙惊吓过度，流血过多
终于不支倒地

102
00:11:55,306 --> 00:11:56,796
掠食者的攻击奏效

103
00:11:59,643 --> 00:12:01,201
扁兽龙无力再战

104
00:12:02,212 --> 00:12:04,442
后鳄兽轻松得手

105
00:12:15,893 --> 00:12:17,190
干季持续了数周

106
00:12:18,095 --> 00:12:19,926
仅剩下河边还有绿地

107
00:12:21,265 --> 00:12:23,529
自然吸引远道而来的动物

108
00:12:24,101 --> 00:12:26,069
例如陪天翼龙

109
00:12:27,571 --> 00:12:32,372
这只飞行爬虫衍生出长指
支撑脆弱的翼膜

110
00:12:40,084 --> 00:12:43,076
蜻蜓是河边常见的飞行猎人

111
00:12:46,623 --> 00:12:50,184
此类昆虫在爬虫出现前
就开始演化

112
00:12:51,128 --> 00:12:54,427
约在更早的一亿年前
就飞上天际

113
00:12:54,865 --> 00:12:56,389
成为空中杀手

114
00:12:58,135 --> 00:13:02,071
不过到了三叠纪时
蜻蜓反而成为猎物

115
00:13:18,622 --> 00:13:22,683
陪天翼龙满口尖牙
容易消化昆虫

116
00:13:26,964 --> 00:13:30,456
陪天翼龙的骨骼
质轻坚韧，适合飞行

117
00:13:31,468 --> 00:13:34,164
它们和恐龙一样，又快又狠

118
00:13:39,008 --> 00:13:41,067
爬虫类开始称霸天空

119
00:13:45,114 --> 00:13:46,877
顶着摄氏40度的高温

120
00:13:47,416 --> 00:13:50,214
扁兽龙
不得不补充大量水分

121
00:13:50,819 --> 00:13:52,650
逗留河边的时间延长

122
00:13:53,789 --> 00:13:57,122
扁兽龙感到不安
因为河边常有埋伏

123
00:14:05,166 --> 00:14:06,793
后鳄兽不是来打猎

124
00:14:09,270 --> 00:14:12,433
只是刚吃饱
所以也想到河边喝水

125
00:14:18,913 --> 00:14:23,646
后鳄兽身长六公尺
体格强壮，背有坚甲

126
00:14:24,152 --> 00:14:25,881
它必须摄取大量食物

127
00:14:26,221 --> 00:14:28,519
因此也得巩固大片地盘

128
00:14:33,461 --> 00:14:35,725
它唯一的敌人就是同类

129
00:14:54,716 --> 00:14:58,482
干旱肆虐，数月来没下过雨

130
00:14:59,688 --> 00:15:02,054
丛林中的小河逐渐干涸

131
00:15:03,224 --> 00:15:05,385
陪天翼龙冒险下水

132
00:15:12,200 --> 00:15:14,998
但它随时提高警觉

133
00:15:26,481 --> 00:15:29,609
大热天里，犬牙兽悠闲乘凉

134
00:15:31,419 --> 00:15:34,047
可惜世上没有绝对的安全

135
00:15:39,094 --> 00:15:41,722
母虚形龙闻到巢穴的气味

136
00:15:42,197 --> 00:15:43,789
开始查探洞口

137
00:15:45,533 --> 00:15:47,330
并且还有同类加入

138
00:16:00,215 --> 00:16:02,342
它们显然没见过犬牙兽

139
00:16:14,162 --> 00:16:18,258
扁兽龙在附近干蕨类底下
寻找含水的根茎

140
00:16:25,974 --> 00:16:28,135
后鳄兽又得进食了

141
00:16:29,310 --> 00:16:32,177
上次行动
它的大腿被长牙刺伤

142
00:16:33,114 --> 00:16:35,241
这对巨型动物伤害极大

143
00:16:44,959 --> 00:16:47,689
它来不及埋伏
就被扁兽龙发现了

144
00:16:48,663 --> 00:16:50,494
扁兽龙展开激烈反击

145
00:16:53,868 --> 00:16:55,426
它无法在此猎食

146
00:16:56,137 --> 00:16:57,627
加上环境竞争激烈

147
00:16:58,239 --> 00:17:00,207
脚伤会是它的致命伤

148
00:17:04,179 --> 00:17:07,376
入夜后
洞里的犬牙兽准备出猎

149
00:17:10,852 --> 00:17:14,413
幼犬牙兽大了不少
开始在窝里活动

150
00:17:14,923 --> 00:17:17,187
但是仍相当脆弱

151
00:17:17,659 --> 00:17:20,787
需要再让父母照顾两个月
才能独立

152
00:17:27,001 --> 00:17:29,970
公犬牙兽
察看河岸，确认安全

153
00:17:43,718 --> 00:17:46,312
好奇的幼兽
跟着父亲来到洞口

154
00:18:05,206 --> 00:18:07,640
父亲来不及保护小犬牙兽

155
00:18:19,053 --> 00:18:20,850
它再度驱离虚形龙

156
00:18:22,423 --> 00:18:24,550
但是这一次它们不肯走远

157
00:18:27,929 --> 00:18:32,559
附近一头干渴的公后鳄兽
入侵了受伤母兽的地盘

158
00:18:34,202 --> 00:18:36,932
但是在这片干旱的
三叠纪大地上

159
00:18:37,839 --> 00:18:41,172
两头后鳄兽
无法共享将干的谷地

160
00:19:03,932 --> 00:19:05,661
母后鳄兽无力抵御

161
00:19:09,537 --> 00:19:12,404
占领了十年的地盘
只好拱手让人

162
00:19:16,042 --> 00:19:20,035
公后鳄兽利用珍贵水源
划定势力范围

163
00:19:29,355 --> 00:19:32,153
这时虚形龙准备挖出犬牙兽

164
00:19:36,962 --> 00:19:38,793
犬牙兽情况危急

165
00:19:40,599 --> 00:19:42,362
巢穴即将瓦解

166
00:19:52,278 --> 00:19:55,372
日落后，犬牙兽别无选择

167
00:19:56,615 --> 00:20:01,848
只好忍痛割舍亲情
自行吃下幼兽

168
00:20:03,022 --> 00:20:05,013
不让恐龙获得食物

169
00:20:06,559 --> 00:20:08,083
并准备伺机逃逸

170
00:20:21,307 --> 00:20:23,434
它们趁夜晚弃巢而逃

171
00:20:38,724 --> 00:20:40,851
早晨，虚形龙重回原地

172
00:20:42,061 --> 00:20:42,993
犬牙兽的气味仍在

173
00:20:43,829 --> 00:20:46,764
它们后来才知道
自己白费力气了

174
00:21:03,949 --> 00:21:05,007
干旱依旧

175
00:21:06,385 --> 00:21:10,116
虚形龙扑空后
在干河床上另有斩获

176
00:21:11,123 --> 00:21:12,112
它找到了肺鱼

177
00:21:14,160 --> 00:21:17,823
虚形龙的特殊锯齿
利于切开肺鱼厚茧

178
00:21:21,233 --> 00:21:22,791
可惜它无法独享

179
00:21:33,512 --> 00:21:37,710
虚形龙数量日增
冲突在所难免

180
00:21:57,403 --> 00:22:00,497
族群增加的压力
也造成了行为的转变

181
00:22:06,212 --> 00:22:15,917
烈日当空，虚形龙集体狩猎
受伤的母后鳄兽后脚残废

182
00:22:17,489 --> 00:22:19,923
但是它的强力双颚
仍可重创虚形龙

184
00:22:44,715 --> 00:22:46,649
食肉恐龙的力量尽失

185
00:22:50,555 --> 00:22:52,853
后鳄兽一身厚甲与肌肉

186
00:22:53,324 --> 00:22:56,350
沦为敏捷小型恐龙的食物

187
00:22:57,962 --> 00:23:00,988
虚形龙口鼻部长，前牙锐利

188
00:23:01,432 --> 00:23:04,799
可穿透后鳄兽厚鳞
啃食它的内部

189
00:23:31,329 --> 00:23:32,762
雨季迟迟不来

190
00:23:32,997 --> 00:23:35,295
生存考验也因而展开

191
00:23:36,701 --> 00:23:38,794
大地变成红色沙漠

192
00:23:40,004 --> 00:23:43,167
扁兽龙被迫迁徙，寻找水源

193
00:23:56,687 --> 00:23:58,314
虽然旱灾严重

194
00:23:58,823 --> 00:24:01,553
恐龙却比其他爬虫类占忧势

195
00:24:02,260 --> 00:24:05,559
因为恐龙排泄时
消耗极少水分

196
00:24:09,466 --> 00:24:12,333
这项忧势在干河岸一目了然

197
00:24:13,737 --> 00:24:16,171
大量的虚形龙群居一处

198
00:24:16,840 --> 00:24:20,139
多年干旱
恐龙是最后的战胜者

199
00:24:21,445 --> 00:24:23,174
其他爬虫类不易存活

200
00:24:24,348 --> 00:24:25,747
一旦猎物不足

201
00:24:26,216 --> 00:24:28,047
恐龙转而自相残杀

202
00:24:31,421 --> 00:24:33,855
同类相食相当普遍

203
00:24:38,461 --> 00:24:41,225
三叠纪的生物面临绝境

204
00:24:51,907 --> 00:24:55,673
入夜后可以看出
恐龙不是唯一生还者

205
00:24:58,414 --> 00:25:00,245
犬牙兽侥幸存活

206
00:25:01,550 --> 00:25:03,245
藏身干蕨类下的洞穴

207
00:25:05,454 --> 00:25:07,945
公犬牙兽仍在晚上出猎

208
00:25:16,098 --> 00:25:17,759
它捕捉到了唯一的猎物…

209
00:25:20,970 --> 00:25:22,665
那是一只小虚形龙

210
00:25:41,390 --> 00:25:45,451
旱灾持续了九个月
终于天降甘霖

211
00:26:19,795 --> 00:26:23,822
干燥的灌木丛林
一下子就得到了滋润

212
00:26:37,780 --> 00:26:41,181
母犬牙兽刚在洞穴里
产下一窝蛋

213
00:26:42,785 --> 00:26:45,015
它们为后代投注了心力

214
00:26:45,821 --> 00:26:48,381
不久就能孕育出
未来的晡乳类

215
00:26:50,226 --> 00:26:53,093
晡乳类的演化期
长达一亿六千万年

216
00:26:54,296 --> 00:26:57,891
恐龙统治时代
仅有少数小型晡乳类存活

217
00:27:04,440 --> 00:27:06,305
洞外的未来已经来临

218
00:27:11,213 --> 00:27:13,238
母虚形龙战胜了干旱

219
00:27:14,550 --> 00:27:17,110
其他许多同伴也熬过来了

220
00:27:21,490 --> 00:27:23,651
另一种恐龙也活了下来

221
00:27:37,673 --> 00:27:41,404
一大群板龙
受丰沛河水吸引而来

222
00:27:42,144 --> 00:27:46,205
很难想像
板龙和虚形龙是同类

223
00:27:46,849 --> 00:27:49,079
但是板龙属于草食恐龙

224
00:27:54,289 --> 00:27:56,917
体型大是板龙的生存忧势

225
00:27:57,492 --> 00:28:00,427
它重达四吨，根本不怕威胁

226
00:28:06,467 --> 00:28:08,128
一切渐具雏形

227
00:28:09,204 --> 00:28:11,229
恐龙时代从此登场
