1 00:00:16,560 --> 00:00:21,606 Surely one of the most remarkable animals that had ever existed, 2 00:00:22,148 --> 00:00:26,361 and certainly one of the most famous, is a dinosaur. 3 00:00:27,404 --> 00:00:29,656 Tyrannosaurus rex. 4 00:00:30,699 --> 00:00:35,245 An animal to spark the imagination for all of us. 5 00:00:35,328 --> 00:00:38,290 What kind of an animal was it? 6 00:00:38,373 --> 00:00:41,585 What did it look like? How did it live? 7 00:00:41,668 --> 00:00:45,630 Now, scientific research has answered such questions. 8 00:00:45,714 --> 00:00:47,966 And not just about T. rex, 9 00:00:48,049 --> 00:00:51,386 but the other species that lived alongside it. 10 00:00:51,469 --> 00:00:58,059 And the latest imaging technology enables us to bring them all to life. 11 00:01:01,980 --> 00:01:05,901 Planet Earth, 66 million years ago. 12 00:01:13,992 --> 00:01:17,537 The skies are filled with flying giants. 13 00:01:20,081 --> 00:01:24,127 In the seas, monstrous reptiles patrol the depths. 14 00:01:26,171 --> 00:01:29,299 And on land, dinosaurs of every kind, 15 00:01:30,508 --> 00:01:33,261 all facing the struggle to survive. 16 00:01:39,434 --> 00:01:45,732 We now know so much about a world that was ruled by the dinosaurs. 17 00:01:49,694 --> 00:01:52,239 This is their story. 18 00:02:09,381 --> 00:02:12,884 The southern shores of the great inland sea 19 00:02:12,968 --> 00:02:14,970 that splits North America. 20 00:02:23,311 --> 00:02:27,107 And the tracks of the land's top predator. 21 00:02:32,612 --> 00:02:36,533 A Tyrannosaurus rex taking a swim. 22 00:02:39,869 --> 00:02:43,164 Hollow, air-filled bones and powerful hind limbs 23 00:02:43,248 --> 00:02:46,418 make T. rex very effective swimmers. 24 00:02:52,424 --> 00:02:58,638 This is an adult male with his young family. 25 00:03:02,267 --> 00:03:06,479 His offspring are now just old enough to follow him on a journey 26 00:03:06,980 --> 00:03:10,984 to one of the many offshore islands that fringe this coast. 27 00:03:34,466 --> 00:03:38,845 It's a short enough crossing, but it can still be a dangerous one. 28 00:03:44,309 --> 00:03:45,727 A mosasaur. 29 00:03:45,810 --> 00:03:49,981 A giant marine lizard over twice the size of a tyrannosaur 30 00:03:50,065 --> 00:03:52,484 and weighing over 15 tons. 31 00:04:03,161 --> 00:04:05,622 It's the largest predator on the planet. 32 00:04:13,797 --> 00:04:17,007 Turtles are normally on a mosasaur's menu. 33 00:04:19,344 --> 00:04:23,557 But this brood would make a welcome snack. 34 00:04:33,900 --> 00:04:36,570 An adult T. rex, even in water, 35 00:04:36,653 --> 00:04:39,322 could still defend itself very effectively. 36 00:04:43,827 --> 00:04:45,912 But the young must stay close. 37 00:05:30,373 --> 00:05:34,002 Tyrannosaurus rex often lose at least two-thirds 38 00:05:34,085 --> 00:05:38,215 of their original brood of 15 or so in the first year. 39 00:05:45,597 --> 00:05:48,225 Now there are only four. 40 00:05:57,776 --> 00:06:01,196 The island offers safety and the promise of food. 41 00:06:02,113 --> 00:06:05,825 Giant two-ton turtles are here to nest. 42 00:06:10,163 --> 00:06:12,832 But this is the one that has drawn him here. 43 00:06:17,254 --> 00:06:21,174 It's dead, and the tyrannosaur has smelled its rotting body. 44 00:06:33,019 --> 00:06:35,438 If he can just get to the underbelly, 45 00:06:35,522 --> 00:06:39,109 he will have over 2,000 pounds of easy meat. 46 00:06:54,791 --> 00:06:58,587 T. rex has the most powerful jaws in nature. 47 00:07:00,714 --> 00:07:04,509 And can b***e with the force of over five tons. 48 00:07:06,469 --> 00:07:12,017 The young are keen for a taste, but he's not sharing it. 49 00:07:12,601 --> 00:07:15,520 It's time for them to learn to hunt for themselves. 50 00:07:18,106 --> 00:07:21,151 The beach, however, doesn't look very promising. 51 00:07:27,574 --> 00:07:31,953 But as the evening approaches, things start to change. 52 00:07:38,043 --> 00:07:43,506 Baby turtles are beginning to hatch from the sand and rush down to the sea. 53 00:07:55,268 --> 00:07:59,272 The young T. rex have been brought to an ideal training ground. 54 00:08:06,112 --> 00:08:10,116 Hatchling turtles are the perfect size for a novice to tackle. 55 00:08:19,042 --> 00:08:23,004 It pays for any hunter to be inquisitive. 56 00:08:40,020 --> 00:08:42,440 There's a lot to learn. 57 00:08:55,662 --> 00:09:00,375 And there's enough food here to satisfy both parent and young. 58 00:09:09,676 --> 00:09:11,303 And if all else fails, 59 00:09:11,386 --> 00:09:14,764 you can always steal supper from someone else. 60 00:09:35,785 --> 00:09:37,078 Across the globe, 61 00:09:37,162 --> 00:09:43,168 these shallow coastal seas cover an area of 25 million square miles. 62 00:09:43,251 --> 00:09:46,171 Far more than even the largest continent. 63 00:09:48,215 --> 00:09:51,009 That, combined with the richness of the waters, 64 00:09:51,092 --> 00:09:53,720 makes them very important habitat. 65 00:09:59,935 --> 00:10:02,145 Wherever land meets sea, 66 00:10:02,229 --> 00:10:06,650 nutrients rise from the deep, fueling an abundance of life. 67 00:10:09,402 --> 00:10:12,697 It's especially rich here in the North Atlantic, 68 00:10:12,781 --> 00:10:16,785 where huge shoals of fish come close to the shore. 69 00:10:26,670 --> 00:10:32,384 One kind of animal thrives in such places and forms immense colonies. 70 00:10:37,556 --> 00:10:40,600 Flying reptiles. Pterosaurs. 71 00:10:41,518 --> 00:10:46,398 Here, on the beaches of North Africa, there are seven different species of them. 72 00:10:49,192 --> 00:10:53,780 They come here to feed, to rest, and to raise their young. 73 00:10:56,658 --> 00:11:00,453 Tethydraco are well-adapted to spend time on the ground 74 00:11:00,537 --> 00:11:04,749 and not only make their nests here but stay to protect their brood. 75 00:11:10,005 --> 00:11:12,966 And their young certainly need protection. 76 00:11:17,554 --> 00:11:20,599 The dagger beak of Phosphatodraco. 77 00:11:28,106 --> 00:11:31,902 A nine-foot-tall predator that stalks through these colonies, 78 00:11:31,985 --> 00:11:35,572 looking for a chance to snatch an unguarded hatchling. 79 00:11:41,786 --> 00:11:45,957 But some types of pterosaurs are less well-adapted to life on land. 80 00:11:46,041 --> 00:11:49,502 They have a slightly different nesting strategy. 81 00:11:52,464 --> 00:11:56,635 They make their nests where they will attract less attention from predators. 82 00:11:58,011 --> 00:12:00,889 Isolated cliffs like this are ideal. 83 00:12:03,475 --> 00:12:07,687 Pterosaur eggs are leathery and can easily dry out, 84 00:12:07,771 --> 00:12:09,981 so they need to be covered. 85 00:12:11,691 --> 00:12:15,904 Beneath this pile of seaweed, something is stirring. 86 00:12:22,202 --> 00:12:25,872 A tiny Alcione hatchling, just a few inches high 87 00:12:25,956 --> 00:12:28,250 and weighing less than two ounces. 88 00:12:34,047 --> 00:12:37,467 Their mothers left the eggs here about two months ago. 89 00:12:51,565 --> 00:12:54,568 Calling to each other synchronizes hatching. 90 00:12:55,610 --> 00:12:58,113 There is safety in numbers. 91 00:13:02,617 --> 00:13:05,495 Their first instinct is to climb. 92 00:13:29,394 --> 00:13:33,315 Hatchlings from hundreds of nests gather on the cliff-top 93 00:13:33,398 --> 00:13:35,650 to prepare for their first flight. 94 00:13:44,159 --> 00:13:46,411 But their wings are still unformed. 95 00:13:47,662 --> 00:13:51,082 The bones of the long finger that supports their wing membrane 96 00:13:51,166 --> 00:13:56,171 must first straighten and lock together, and that will take some hours. 97 00:13:59,090 --> 00:14:00,884 But they can't stay here for long. 98 00:14:08,350 --> 00:14:12,270 Their bones are extremely light, up to 90% air, 99 00:14:12,354 --> 00:14:15,815 and that makes the effort needed to take off much easier. 100 00:14:18,652 --> 00:14:21,696 Even so, test flights are essential. 101 00:14:23,073 --> 00:14:26,034 There will only be one chance to get it right 102 00:14:26,117 --> 00:14:28,078 when the time comes to launch. 103 00:14:35,669 --> 00:14:39,506 The cliff edge creates updrafts, and they can help. 104 00:14:39,589 --> 00:14:43,718 So, it pays to gather there facing into the prevailing winds 105 00:14:43,802 --> 00:14:45,929 and towards the mainland. 106 00:14:49,391 --> 00:14:52,602 But no one seems quite ready to take the plunge. 107 00:14:59,693 --> 00:15:04,906 Until, at last, one youngster sets them all on their way. 108 00:15:44,821 --> 00:15:47,490 They're not heading for the beach and its colony. 109 00:15:47,574 --> 00:15:52,078 They need to get to the mist forest that lies beyond. 110 00:16:00,795 --> 00:16:02,255 Barbaridactylus. 111 00:16:02,964 --> 00:16:06,927 Powerful, predatory pterosaurs that normally catch fish. 112 00:16:07,719 --> 00:16:10,680 But the hatchlings are too good to miss. 113 00:16:19,856 --> 00:16:24,945 One way to take evasive action is to simply fold their wings and drop. 114 00:16:32,077 --> 00:16:36,039 But losing height will make it harder for them to reach the forests. 115 00:17:13,159 --> 00:17:15,411 A crash landing in the colony. 116 00:17:15,495 --> 00:17:18,540 It's no place for a hatchling on its own. 117 00:17:42,814 --> 00:17:46,651 A lucky survivor from the first wave of...
