== 梁氏出品 必属精品 ==

1
00:00:35,001 --> 00:00:38,437
晨光照耀
南极数百哩外的寂静森林

2
00:00:40,640 --> 00:00:42,437
数月的永夜结束了

3
00:00:43,910 --> 00:00:47,209
阳光洒落森林
只见冰封大地

4
00:00:50,850 --> 00:00:52,647
极地恐龙在这里生存

5
00:00:53,686 --> 00:00:55,551
它们虽能适应恶劣的环境

6
00:00:56,156 --> 00:00:58,556
但也必须在险境求生

7
00:01:15,809 --> 00:01:19,870
尽管南极春季的首日
光明仅持续几分钟

8
00:01:20,413 --> 00:01:23,541
但是却揭开了
极地求生录的序幕

9
00:01:46,573 --> 00:01:47,437
白垩纪中期

10
00:01:48,508 --> 00:01:52,274
恐龙广布地球各处
盛况空前

11
00:01:54,013 --> 00:01:56,345
唯有南极地方尚待征服

12
00:01:58,518 --> 00:02:02,614
这块大陆由南美洲
澳洲与南极洲构成

13
00:02:03,890 --> 00:02:05,619
此地受洋流暖化

14
00:02:07,594 --> 00:02:10,461
洋流自赤道而下
再回流赤道

15
00:02:13,900 --> 00:02:16,630
此时南极没有冰帽
树木茂盛

16
00:02:17,637 --> 00:02:20,800
南极与其他热带气侯不同
有四季之分

17
00:02:21,708 --> 00:02:23,369
炎夏午夜，艳阳高照

18
00:02:24,144 --> 00:02:26,203
寒冬永夜，不见天日

19
00:02:33,486 --> 00:02:36,250
雷利诺龙能适应
这种极端气侯

20
00:02:40,360 --> 00:02:43,557
冬天它们在温暖浓密的
森林中央避寒

21
00:02:44,764 --> 00:02:48,359
在春天重出江湖
摄取鲜嫩植物

22
00:02:51,938 --> 00:02:53,929
雷利诺龙仅两公尺长

23
00:02:54,908 --> 00:02:56,876
大眼是它们的明显特征

24
00:02:57,443 --> 00:02:59,411
有助于冬季永夜期觅食

25
00:03:02,581 --> 00:03:04,947
雷利诺龙与家族群居而生

26
00:03:05,618 --> 00:03:07,609
以便善用稀有资源

27
00:03:09,355 --> 00:03:11,789
由一对繁殖配偶领导家族

28
00:03:12,525 --> 00:03:15,323
阶级分工，随时有族员防守

29
00:03:17,129 --> 00:03:20,257
只要岸边安全
它就会定时报平安

30
00:03:52,698 --> 00:03:55,826
哨兵发现巨大的两栖类
酷拉鳄螈

31
00:03:56,735 --> 00:03:58,293
它的双颚强而有力

32
00:03:58,904 --> 00:04:01,702
重约半吨，是肉食动物

33
00:04:09,081 --> 00:04:10,912
酷拉鳄螈是水中杀手

34
00:04:11,584 --> 00:04:14,519
一旦上岸
四肢无法支撑体重

35
00:04:15,020 --> 00:04:17,113
对雷利诺龙不构成威胁

36
00:04:21,260 --> 00:04:23,228
酷拉鳄螈之前在森林冬眠

37
00:04:24,129 --> 00:04:28,327
如今得爬行两百公尺
回到河里，享受夏天

38
00:04:37,610 --> 00:04:41,774
长相怪异的酷拉鳄螈
出现年代比恐龙更早

39
00:04:42,715 --> 00:04:46,913
在大部份地区
酷拉鳄螈被鳄鱼追杀殆尽

40
00:04:48,287 --> 00:04:51,723
但南极水温冰冷
不适合鳄鱼生存

41
00:04:52,524 --> 00:04:55,550
反而成了酷拉鳄螈的
最后栖息地

42
00:04:55,995 --> 00:04:57,587
得以悠游水中

43
00:04:57,997 --> 00:05:01,091
延续一亿五千万年来的
生活模式

44
00:05:27,760 --> 00:05:30,422
大地回春，白昼渐长

45
00:05:31,196 --> 00:05:32,458
森林恢复生机

46
00:05:46,245 --> 00:05:47,769
这片蕨类、针叶林中

47
00:05:48,480 --> 00:05:52,280
许多植物经过特化
可在永夜时休眠

48
00:05:54,119 --> 00:05:57,577
春天日光照射
才恢复光合作用

49
00:06:07,199 --> 00:06:09,360
雷利诺龙家族也开始忙碌

50
00:06:10,736 --> 00:06:12,397
它们在春季首日交配

51
00:06:13,105 --> 00:06:14,504
现在开始筑巢

52
00:06:17,274 --> 00:06:18,639
全族分工合作

53
00:06:19,476 --> 00:06:23,503
配偶居中布置巢穴
其余族员在旁支援

54
00:06:25,182 --> 00:06:27,582
众多树叶堆下
不见得都有蛋

55
00:06:28,219 --> 00:06:31,086
但是可作为幌子
保护主要巢穴

56
00:06:33,257 --> 00:06:34,588
雷利诺龙不论多忙

57
00:06:35,092 --> 00:06:36,616
仍然会保持警戒

58
00:06:45,402 --> 00:06:47,768
极地异特龙是夏日的访客

59
00:06:48,372 --> 00:06:50,533
来自北方较温暖的地区

60
00:06:56,246 --> 00:06:58,771
它重达一吨，擅长突击

61
00:07:24,641 --> 00:07:27,974
异特龙是森林里
最大最凶狠的掠食者

62
00:07:28,679 --> 00:07:30,909
雷利诺龙哨兵早注意到它

63
00:07:31,448 --> 00:07:33,109
全族潜入矮树丛里

64
00:07:33,817 --> 00:07:36,877
雷利诺龙迅速敏捷
异特龙跟不上

65
00:07:47,197 --> 00:07:50,530
春季降临森林
许多动物展开迁移

66
00:07:51,468 --> 00:07:54,437
翼龙成群南飞
前往夏季栖地

67
00:07:58,041 --> 00:08:00,407
森林里传来陌生叫声

68
00:08:03,914 --> 00:08:06,712
最壮硕的夏季旅客抵达森林

69
00:08:31,608 --> 00:08:34,543
声势壮大的木他龙来自北方

70
00:08:38,315 --> 00:08:40,977
两个月来
它们跋涉八百公里

71
00:08:41,351 --> 00:08:43,979
循着太阳南进
来到澳洲海岸

72
00:08:46,890 --> 00:08:50,917
木他龙每年进驻南极地方
享用丰富植物

73
00:08:51,428 --> 00:08:53,191
并寻找安全地点产卵

74
00:08:59,669 --> 00:09:01,830
它们对森林冲击甚大

75
00:09:02,806 --> 00:09:04,637
成年木他龙重约三吨

76
00:09:05,475 --> 00:09:08,103
数公尺高的树枝也照吃不误

77
00:09:10,447 --> 00:09:13,678
木他龙进食时
仍不时与同伴联系

78
00:09:14,317 --> 00:09:17,912
以特化的鼻囊
发出多种声响沟通

79
00:09:23,926 --> 00:09:25,655
由于森林日渐拥挤

80
00:09:26,395 --> 00:09:28,420
雷利诺龙必须守侯巢穴

81
00:09:30,165 --> 00:09:32,190
母雷利诺龙
把烂树叶堆当做保温箱

82
00:09:32,201 --> 00:09:33,998
母雷利诺龙
把烂树叶堆当做保温箱

83
00:09:34,502 --> 00:09:37,096
并以敏感的嘴喙监控温度

84
00:09:37,939 --> 00:09:41,773
依温度加减叶片
维持在摄氏30度

85
00:09:43,611 --> 00:09:45,602
小雷利诺龙在巢内呼叫

86
00:09:46,147 --> 00:09:47,671
回应母亲的呼唤

87
00:09:54,889 --> 00:09:57,824
雷利诺龙必须全天侯守侯巢穴

88
00:09:59,226 --> 00:10:02,093
覆毛的晡乳动物
遍布南极森林

89
00:10:02,697 --> 00:10:05,029
体型稍大者便可偷恐龙蛋

90
00:10:10,171 --> 00:10:12,071
雷利诺龙自有防御方法

91
00:10:22,914 --> 00:10:24,882
这招专治偷蛋贼

92
00:10:26,918 --> 00:10:29,284
但其他偷蛋贼还会上门来

93
00:10:38,697 --> 00:10:41,188
木他龙陆续抵达泛滥平原

94
00:10:42,067 --> 00:10:44,467
森林里的掠食者虎视眈眈

95
00:10:50,675 --> 00:10:55,135
异特龙试探木他龙
想找老弱残兵下手

96
00:10:56,448 --> 00:10:58,507
草食的木他龙行动迟缓

97
00:10:59,516 --> 00:11:02,041
靠体型与数量躲避危险

98
00:11:26,042 --> 00:11:29,500
异特龙不敌强健的公木他龙
被迫撤退

99
00:11:37,386 --> 00:11:40,378
晚春时
树蕨与针叶林繁生

100
00:11:40,890 --> 00:11:44,121
形成浓密树冠
吸取所有阳光

101
00:11:49,365 --> 00:11:51,959
巢穴大多已遭受
掠食者洗劫

102
00:11:52,868 --> 00:11:55,996
但是起码还是保住了
族群的领导命脉

103
00:11:58,374 --> 00:12:00,308
三只幼龙安居巢内

104
00:12:03,446 --> 00:12:06,472
出生后前两周
幼龙躲在巢内

105
00:12:06,916 --> 00:12:09,180
等待大恐龙轮流带回食物

106
00:12:21,564 --> 00:12:23,555
母龙极力守护巢穴

107
00:12:27,336 --> 00:12:29,827
为了避免掠食者发现
幼龙的气味

108
00:12:30,406 --> 00:12:33,671
它移走蛋壳
吃下未孵化的蛋

109
00:12:35,544 --> 00:12:37,876
这样可以顺便补充营养

110
00:12:52,795 --> 00:12:54,626
初生幼龙相当脆弱

111
00:12:55,331 --> 00:12:56,730
很容易在森林里走失

112
00:12:59,835 --> 00:13:03,532
大恐龙莫不极力看护
以免掠食者入侵

113
00:13:07,376 --> 00:13:10,470
幼龙将在数周内茁壮
跟上大恐龙

114
00:13:11,180 --> 00:13:13,876
但是现在必须随时待在巢里

115
00:13:25,761 --> 00:13:28,389
夏季来临，永昼开始

116
00:13:29,065 --> 00:13:31,932
太阳将持续五个月高挂天空

117
00:13:32,968 --> 00:13:35,266
每年此时
在巢穴附近的林地

118
00:13:35,838 --> 00:13:37,567
极地昆虫大量孳生

119
00:13:38,474 --> 00:13:40,237
沙螽便在树叶堆中觅食

120
00:13:45,681 --> 00:13:48,980
沙螽本身也是
斑点楔齿蜥等动物的食物

121
00:13:50,252 --> 00:13:52,413
斑点楔齿蜥属于爬虫类

122
00:13:53,556 --> 00:13:55,148
它出现的年代早于恐龙

123
00:13:55,658 --> 00:13:57,785
生存时间也远超过恐龙

124
00:13:58,694 --> 00:14:00,218
活动于日后的纽西兰

125
00:14:04,200 --> 00:14:07,169
野地的木他龙
饱受吸血虫的折磨

126
00:14:10,106 --> 00:14:12,540
夏天引诱大批吸血蝇

127
00:14:13,275 --> 00:14:15,368
恐龙虽有坚硬鳞片表皮

128
00:14:16,078 --> 00:14:18,205
仍有部份柔软皮肤

129
00:14:19,115 --> 00:14:21,583
吸血虫专攻耳朵内部等处

130
00:14:22,218 --> 00:14:24,812
穿透皮肤，吸血饱食

131
00:14:36,197 --> 00:14:37,687
木他龙招架不住

132
00:14:38,366 --> 00:14:39,663
只好尽快远离河边

133
00:14:48,608 --> 00:14:51,839
雷利诺龙在森林里
享用夏日飨宴

134
00:14:52,578 --> 00:14:55,206
危机四伏，仍照睡不误

135
00:14:56,315 --> 00:14:57,646
漫长的永昼期间

136
00:14:58,317 --> 00:15:01,912
雷利诺龙全靠保护色
藏身蕨类丛里

137
00:15:08,494 --> 00:15:11,463
幼龙自然不想睡觉
在附近玩耍

138
00:15:12,465 --> 00:15:14,660
茁壮的幼龙，练习闪躲技巧

139
00:15:15,535 --> 00:15:17,332
这是日后的救命绝招

140
00:15:26,212 --> 00:15:30,308
幼龙所到之处
母龙总在附近守护

141
00:15:30,883 --> 00:15:32,316
照顾日渐活泼的幼龙

142
00:15:42,061 --> 00:15:45,360
一只老木他龙遭受攻击
死在河岸

143
00:15:46,566 --> 00:15:48,363
公异特龙忙着啃食腐肉

144
00:15:53,039 --> 00:15:55,132
极地异特龙的祖先是

145
00:15:55,741 --> 00:15:58,574
五千年前侏罗纪的
一种大型肉食恐龙

146
00:16:00,079 --> 00:16:03,515
在白垩纪时期
这样的品种很罕见

147
00:16:04,016 --> 00:16:05,506
仅存活于南极地方

148
00:16:11,524 --> 00:16:14,789
虽然食物充足
够20只异特龙食用

149
00:16:15,361 --> 00:16:17,192
它也不允许同类靠近

150
00:16:36,983 --> 00:16:38,848
母异特龙遭到驱离

151
00:16:46,926 --> 00:16:50,828
成年的极地异特龙
每周须摄取一百公斤的肉

152
00:16:51,831 --> 00:16:54,356
它得等公龙吃饱了再过来

153
00:17:02,341 --> 00:17:03,899
永昼午夜过后不久

154
00:17:05,011 --> 00:17:07,775
一只小雷利诺龙
独自到河边冒险

155
00:17:34,774 --> 00:17:37,242
幸亏它反应快，逃过一劫

156
00:17:41,580 --> 00:17:45,311
森林危机重重
小雷利诺龙有得学了

157
00:17:56,529 --> 00:17:59,692
恐龙时代
南极夏季常发生雷雨

158
00:18:01,334 --> 00:18:04,303
雷雨横扫极地森林
引发水灾

159
00:18:10,008 --> 00:18:13,944
洪水肆虐，动物拢聚
可能引发冲突

161
00:18:21,886 --> 00:18:23,615
雷利诺龙发现竞争者

162
00:18:24,455 --> 00:18:26,389
双方恐怕将爆发恶斗

163
00:18:28,193 --> 00:18:31,754
雷利诺龙家族必须巩固地盘
避免食物被抢

164
00:18:32,564 --> 00:18:36,227
它们必须表现实力
让外来者打消念头

165
00:18:58,656 --> 00:19:01,147
恫吓奏效，外来者撤退

166
00:19:01,759 --> 00:19:02,885
暂时守住地盘

167
00:19:09,700 --> 00:19:11,861
风雨过后，大水迅速消退

168
00:19:12,836 --> 00:19:14,235
恐龙回到河岸边觅食

169
00:19:18,475 --> 00:19:19,339
食物充足时

170
00:19:19,910 --> 00:19:21,377
草食动物不介意分享

171
00:19:22,880 --> 00:19:25,007
木他龙忙着享用罗汉松

172
00:19:25,816 --> 00:19:27,841
雷利诺龙则穿梭其中

173
00:19:28,352 --> 00:19:30,547
采集散落满地的红果实

174
00:19:43,367 --> 00:19:44,664
它们冒险采集

175
00:19:46,603 --> 00:19:49,697
因为时间有限
森林资源不容浪费

176
00:19:55,846 --> 00:19:56,778
四季运行

177
00:19:57,147 --> 00:19:58,808
四个月来，第一次日落

178
00:20:01,652 --> 00:20:02,710
秋天来临

179
00:20:03,320 --> 00:20:06,312
极地森林准备迎接冬天

180
00:20:20,337 --> 00:20:22,237
河谷的木他龙察觉转变

181
00:20:22,873 --> 00:20:24,170
开始向北迁移

182
00:20:41,425 --> 00:20:43,723
偶有木他龙在森林里迷路

183
00:20:46,897 --> 00:20:48,626
木他龙迷路问题不大

184
00:20:49,500 --> 00:20:52,594
但是雷利诺龙迷路
却攸关生死

185
00:20:58,776 --> 00:21:00,641
木他龙的叫声盖过一切

186
00:21:01,478 --> 00:21:03,708
雷利诺龙听不见危险声响

187
00:21:48,025 --> 00:21:50,357
异特龙杀害了领队的母龙

188
00:21:54,665 --> 00:21:55,927
这是个严重的打击

189
00:22:06,877 --> 00:22:11,405
冬天即将来临
母龙死亡，全族陷入惶恐

190
00:22:26,630 --> 00:22:30,589
天色渐暗
酷拉鳄螈察觉温度降低

191
00:22:31,401 --> 00:22:33,266
不得不离开夏季栖息地

192
00:22:38,242 --> 00:22:39,300
再度进入森林

193
00:22:40,377 --> 00:22:41,969
寻找适当的冬眠地点

194
00:22:42,779 --> 00:22:44,974
度过未来数月的寒冷永夜

195
00:22:55,526 --> 00:22:58,586
阳光减弱
森林植物也跟着改变

196
00:22:59,363 --> 00:23:01,661
停止生长，光合作用中断

197
00:23:03,734 --> 00:23:06,760
有的开始落叶
有的进入休眠

198
00:23:14,611 --> 00:23:16,909
雷利诺龙现在必须费劲觅食

199
00:23:17,848 --> 00:23:21,147
寻找菌类
及深埋在土中的营养根部

200
00:23:26,023 --> 00:23:28,685
入冬后，雷利诺龙为了求生

201
00:23:29,193 --> 00:23:32,060
便移往鲜少结冰的
森林中心区

202
00:23:32,596 --> 00:23:34,587
并持续活动，保持体温

203
00:23:37,000 --> 00:23:38,627
雷利诺龙聚于瀑布时

204
00:23:39,469 --> 00:23:41,937
夏季掠食者的伤害显而易见

205
00:23:42,773 --> 00:23:46,038
母龙已死
只剩一只幼龙存活

206
00:24:00,791 --> 00:24:03,760
秋日将尽，白昼即将消逝

207
00:24:05,062 --> 00:24:07,724
漫漫永夜就此展开

208
00:24:16,206 --> 00:24:20,108
极地森林的生物
面临冰点的致命考验

209
00:24:26,216 --> 00:24:30,915
沙螽等极地生物
让身体结冰，因应寒冬

210
00:24:41,765 --> 00:24:45,064
寂静的森林上空
闪耀着南极光

211
00:25:00,083 --> 00:25:03,348
沉睡的树木下，一片漆黑

212
00:25:03,954 --> 00:25:05,546
透过强化影像

213
00:25:06,123 --> 00:25:07,920
可以看见雷利诺龙族群

214
00:25:11,560 --> 00:25:12,686
恐龙仍在活动

215
00:25:13,495 --> 00:25:15,087
但今年地面结冰

216
00:25:15,731 --> 00:25:17,858
几乎无法翻动土壤

217
00:25:25,574 --> 00:25:27,303
连池塘也结冰了

218
00:25:28,377 --> 00:25:30,937
雷利诺龙靠坚硬口喙取水

219
00:25:43,991 --> 00:25:45,390
森林的低温期不长

220
00:25:46,026 --> 00:25:48,859
处境恶劣，族群秩序瓦解

221
00:25:50,197 --> 00:25:52,028
雷利诺龙前景堪忧

222
00:25:55,236 --> 00:25:56,100
它们深入森林

223
00:26:06,447 --> 00:26:07,971
经过两个月的永夜

224
00:26:08,482 --> 00:26:09,881
寒流再次来袭

225
00:26:12,786 --> 00:26:14,549
雷利诺龙被迫妥协

226
00:26:14,889 --> 00:26:16,823
更进一步演化出御寒法

227
00:26:17,825 --> 00:26:20,487
龙群靠在一起
进入假死状态

228
00:26:21,028 --> 00:26:24,293
身体进入假死状态
才能忍受风寒

229
00:26:24,765 --> 00:26:26,892
但不能超过两天以上

230
00:26:31,906 --> 00:26:33,965
回暖第一个征兆很微弱

231
00:26:34,942 --> 00:26:37,638
躲在岩石下的沙螽
解冻苏醒

232
00:26:38,245 --> 00:26:41,214
因为气温已持续缓慢回升

233
00:26:55,563 --> 00:26:57,861
地平线上，阳光渐强

234
00:26:58,732 --> 00:27:00,256
春天即将来临

235
00:27:06,407 --> 00:27:09,865
雷利诺龙发生骚动
划破森林寂静

236
00:27:10,477 --> 00:27:12,001
两只公龙展开搏斗

237
00:27:12,780 --> 00:27:14,714
现在是雷利诺龙的交配期

238
00:27:15,249 --> 00:27:16,716
公龙争夺领导权

239
00:27:21,455 --> 00:27:23,719
打斗虽然短暂但却剧烈

240
00:27:44,345 --> 00:27:47,906
胜利的公龙掌握大权
选择配偶

241
00:27:49,617 --> 00:27:53,075
雷利诺龙群
总算产生新的领导配偶

242
00:27:53,654 --> 00:27:56,919
年度求生竞赛将再度上演

243
00:28:06,000 --> 00:28:09,595
恐龙能在极地生存
实在是伟大的演化

244
00:28:10,938 --> 00:28:13,532
但是后来全球气温下降

245
00:28:13,941 --> 00:28:15,966
导致南极森林死亡

246
00:28:17,378 --> 00:28:19,608
南极的恐龙也将绝迹

247
00:28:39,233 --> 00:28:39,995
在极地之外

248
00:28:40,501 --> 00:28:42,731
恐龙又活了四千万年才灭亡

249
00:28:46,340 --> 00:28:48,205
在第六集节目中将介绍

250
00:28:48,709 --> 00:28:49,903
恐龙在灭亡之前

251
00:28:50,477 --> 00:28:54,538
如何演化出
地球上最恐怖的掠食者

252
00:28:54,915 --> 00:28:56,109

00:28:56,950 --> 00:28:57,917
感谢赖景阳教授的指导

254
00:28:58,552 --> 00:28:59,109
谢谢观赏
