1 00:00:00,750 --> 00:00:06,750 hello I am going to show you my presentation of the giraffe under the 2 00:00:06,750 --> 00:00:22,410 sanitarium Rex a giraffe in Madrid giraffe and its ancestor the ancestor of 3 00:00:22,410 --> 00:00:34,619 the giraffe is the sanitarium Rex location and where they live the giraffe 4 00:00:34,619 --> 00:00:43,600 and the Desenaterium Rex. Location of giraffes. The giraffes live in the dry 5 00:00:43,600 --> 00:00:53,460 zones south of the Sahara Desert with trees in Africa in open savannas. When 6 00:00:53,460 --> 00:01:03,020 they live, the giraffes live today. Location of the Desenaterium Rex. 7 00:01:03,020 --> 00:01:10,019 The Desenatarian Rex lived in the Iberian Peninsula, in Spain and Portugal. 8 00:01:10,019 --> 00:01:15,019 Then they expanded to Eurasia and Africa. 9 00:01:15,019 --> 00:01:22,019 They found it at a site near Madrid, Cerro de los Batallones. 10 00:01:22,019 --> 00:01:30,019 When they lived, the Desenatarian Rex, from 5 to 11 million years ago. 11 00:01:30,019 --> 00:01:51,909 Characteristics of the giraffe. They are from 4 to 5 meters tall. The giraffe weighs 800 kilos. Giraffes are the only animal born with horns. 12 00:01:51,909 --> 00:01:59,209 They have two horns covered by their skin, called oxycones. 13 00:01:59,209 --> 00:02:04,129 They have a large, dark and coloured tongue. 14 00:02:05,129 --> 00:02:07,790 They have lofty, cunning teeth. 15 00:02:08,569 --> 00:02:10,430 They are herbivores. 16 00:02:10,909 --> 00:02:13,129 They reproduce sexually. 17 00:02:13,689 --> 00:02:16,110 They have internal fertilisation. 18 00:02:16,849 --> 00:02:20,569 They are mammals and they are warm-blooded. 19 00:02:20,569 --> 00:02:24,569 They belonged to the Giraffidae family. 20 00:02:24,569 --> 00:02:31,060 Characteristics of the Descenatarium Rex 21 00:02:31,060 --> 00:02:40,060 They were 2 to 3 meters tall, 2 to 3 meters long and they weighed 800 kilos. 22 00:02:40,060 --> 00:02:45,060 They had four horns covered by their skin, called ossicones. 23 00:02:45,060 --> 00:02:52,900 Ossicons could have evolved to help mates compete with one another for female attention 24 00:02:52,900 --> 00:02:53,900 or territory. 25 00:02:53,900 --> 00:02:58,280 They could also be for thermal regulation. 26 00:02:58,280 --> 00:03:03,620 Female ossicons were half the length and were more slender. 27 00:03:03,620 --> 00:03:09,379 They have a large, dark and coloured tongue. 28 00:03:09,379 --> 00:03:11,819 They are mammals. 29 00:03:11,819 --> 00:03:14,080 They are viviparous. 30 00:03:14,080 --> 00:03:30,080 They are warm-blooded, they reproduce sexually, they have internal fertilization, they are herbivores, they belong to the Giraffidae family. 31 00:03:30,080 --> 00:03:34,080 Characteristics in common of the Giraffidae and the Dysenotherium Bricks. 32 00:03:34,080 --> 00:03:38,080 They have a large, dark and colored tongue. 33 00:03:38,080 --> 00:03:43,080 They have horns covered by their skin, called oxycones. 34 00:03:43,080 --> 00:03:50,360 They are from the Giraffidae family. They are mammals, they are baby parrots, they are herbivores, 35 00:03:50,360 --> 00:03:56,680 they reproduce sexually, they have internal fertilization and they are warm-blooded. 36 00:03:58,120 --> 00:04:03,800 Differences of the Sanitarium Rex and Giraffe and why do I think they have the differences? 37 00:04:03,800 --> 00:04:11,319 This is the Sanitarium Rex and this is the Giraffe. The Sanitarium Rex had four OC cones. 38 00:04:11,319 --> 00:04:13,800 I think it's useful to fight better. 39 00:04:14,680 --> 00:04:18,839 Ossicons could have evolved to help mates compete with one another 40 00:04:18,839 --> 00:04:23,720 for female attention or a territory. They could also be for thermoregulation. 41 00:04:23,720 --> 00:04:29,399 Giraffes have two ossicons, maybe because modern giraffe don't have antlers. 42 00:04:30,839 --> 00:04:37,160 They were two to three meters tall. They were smaller than a giraffe. 43 00:04:38,120 --> 00:04:41,000 They are from four to five meters tall. 44 00:04:41,000 --> 00:04:47,600 I think it helps them to survive better reaching the top of the trees and eating fruits and 45 00:04:47,600 --> 00:04:48,600 leaves. 46 00:04:48,600 --> 00:04:54,699 They are bigger than the Dicenatarium Rex. 47 00:04:54,699 --> 00:04:57,639 They had a medium-length neck. 48 00:04:57,639 --> 00:05:00,600 They had a long neck, the giraffe. 49 00:05:00,600 --> 00:05:07,740 I think it helps them to survive better reaching the top of the trees and eating fruits and 50 00:05:07,740 --> 00:05:16,459 leaves and to see if there are predators around. Giraffes live today. The Cenotaurium rex lived 51 00:05:16,459 --> 00:05:25,259 from 5 million years ago to 11 million years ago. The Cenotaurium rex had grazed their masticatory 52 00:05:25,259 --> 00:05:34,620 features, a larger masseteric fossa, enlarged maxilla, a larger masseter, profundus muscle, 53 00:05:34,620 --> 00:05:42,379 and molars worn out. Giraffes don't consume as much foliage as the sanitarium wrecks because 54 00:05:42,379 --> 00:05:51,819 they can reach high into the trees. They will only feed on the ground when it is scarce or 55 00:05:51,819 --> 00:05:59,740 when they are young due to their size. The favorite food of the giraffes is the acacia. 56 00:05:59,740 --> 00:06:08,459 thanks to their tongue they can't hold the leaves without hurting thick saliva covers the spines 57 00:06:08,459 --> 00:06:24,050 that could swallow the giraffes this way they protect the internal organs by pablo garcia bye bye
