El Tyrannosaurus Rex, conocido como el rey de los dinosaurios, ha fascinado a científicos y entusiastas por igual. Tradicionalmente, se le ha considerado un depredador sordo y lento; sin embargo, investigaciones recientes han revelado un lado sorprendente de este impresionante dinosaurio. En lugar de ser un simple cazador, el T. Rex era un ser complejo y dinámico, mostrando similitudes notables con las aves modernas. Estos descubrimientos han transformado nuestra comprensión sobre su comportamiento social, sugiriendo que el T. Rex anidaba en parejas y cuidaba de sus crías con dedicación.
Imaginemos cómo estas majestuosas criaturas interactuaban entre sí. Las evidencias apuntan a que, al igual que muchas aves actuales, el T. Rex podría haber jugado y socializado, estableciendo lazos con sus compañeros. Este enfoque no solo ofrece una nueva perspectiva sobre su vida diaria, sino que también destaca la importancia de seguir investigando y aprendiendo sobre estos fascinantes reptiles. Además, al comprender mejor el comportamiento del T. Rex, podemos apreciar la complejidad de la evolución y la relación entre los dinosaurios y las aves contemporáneas.
La próxima vez que pienses en el Tyrannosaurus Rex, recuerda que este gigantesco depredador era mucho más que una simple máquina de caza. Su vida estaba llena de matices, afectos y comportamientos sociales que nos acercan a comprender su mundo.

05:11Dino
06:13The cannibalism fulfills a task and is surprisingly common in many modern species.
06:43It's an exciting time to study dinosaurs.
07:12And among them, the T-Rex is probably the most amazing.
07:16Because we have used more new techniques and carried out more types of studies on it in the last decade than with any other species of dinosaur.
07:27One thing we have learned is that a super predator was more likely to be attacked by another super predator.
07:37Any dinosaur had a hard life.
07:40But a predator like the T-Rex had a more difficult life.
07:44In the fossil record, we find many T-Rex skeletons with fractures.
07:51We can find evidence of this in this humerus of a T-Rex.
07:56We observe serious damage to the entire bone, suggesting that they almost tore off his arm.
08:03Possibly another T-Rex.
08:07It is possible that sometimes the T-Rex was the worst enemy of the T-Rex.
08:23A couple of T-Rex lose their retinas after the cannibal attack of a rival.
08:30But life must go on.
08:44Like most dinosaurs, very few T-Rex reach adulthood.
08:52This mother has not been lucky in her favor.
09:22These T-Rex hunt as a team to get the best advantage possible.

13:26Evolution of the dinosaur
13:49We know a lot about its development.
13:51We know that the Tyrannosaurus
13:53had a growth profile similar to that of the human being.
13:56They had a kind of childhood,
13:58they went through a period similar to adolescence,
14:01and they got to be an adult size at the beginning of their twenties.
14:04Most of them probably wouldn't live much longer than their thirties.
14:09Recent discoveries have shown us that the T-Rex was a cannibal.
14:17There are fragments of T-Rex bones
14:19with teeth marks that could only have been made by another T-Rex.
14:23It's a conclusive proof that they fed on other T-Rexes from time to time.
14:31A paleoartist is somebody who recreates
14:34a reasonable assumption of the appearance that a dinosaur may have.
14:38So they work with scientists and study the bones,
14:42where the muscles would go,
14:44what kind of appearance the skin would have,
14:46if it had feathers, other coatings.
14:48Then they put an idea of what it would look like in real life
14:51and also put it in the environment that it actually lived in.
14:54I like to treat dinosaurs as characters.
14:58When I look at a bone, I see not just a creature,
15:01I see someone, and I want to know who that is.
15:03When the average person looks at a dinosaur, a T-Rex,
15:07you know, they see a T-Rex,
15:09but in the many forty-something skeletons of T-Rex
15:12that have been found,
15:14you can actually feel the difference between the skulls,
15:16and you know who is who.
15:18When I look at a fossil,
15:21I want to know who this guy was,
15:23what his life was like.
15:26I want to see the world through his eyes.
15:29Our concept of dinosaurs has changed since I was a child.
15:33You know, now it's common knowledge
15:35that they had to walk in a horizontal position.
15:38Today they look less like lizards and more like birds.
15:42Feathers are totally accepted now.
15:46They're just more interesting, dynamic, visually attractive creatures.
15:52In my lifetime,
15:54dinosaurs have undergone a big overhaul.
15:57There's a lot more genealogy,
15:59how skin may apply,
16:02or how the muscles may have been attached.
16:06And then having this clue that they were related to birds
16:09also gives us a lot more information about their appearance.
16:12So we're going to look at a much more genealogy-backed animal
16:16with a lot more information.
16:29It's hard to imagine a T-Rex worried about his nest,
16:34unless it's part of this dinosaur revolution.
16:39Beginning in the 1980s,
16:41we started finding more and more nests and eggs.
16:44Now we can say with certain confidence
16:47that they looked after their young.
16:50In fact, we have evidence.
16:52In the mid-1990s, in Mongolia,
16:54paleontologists found a skeleton
16:56that's called the oviraptosaurus
16:58sitting on a nest of eggs.
17:00So I think it's a good evidence
17:02that dinosaurs looked after their eggs,
17:04and it's also a good evidence
17:06that they looked after their young.
17:09We know that crocodiles,
17:11who are distant relatives of dinosaurs,
17:13looked after their young,
17:15just like many birds today.
17:17So it's very possible that the Tyrannosaurus
17:19looked after its young.
17:22It seems unlikely that a 6-ton T-Rex
17:25would sit like a bird on a nest of fragile eggs.
17:29It's more likely that it would make a protective cover,
17:33and that was just the beginning of a dangerous journey.
17:37It's very sad to think
17:39that most of the dinosaur babies
17:41were born to die,
17:43and to die when they were really young.
17:46A dinosaur mom would probably
17:48put 10 nests during her life,
17:50and yet in nature,
17:52on average, only one
17:54would reach adulthood for every mother.
17:58Not only the newly hatched young
18:00could be easy prey for predators.
18:02Even incubating the eggs
18:04was a dangerous process.
18:08Montana.
18:1365 million years ago.
18:19Eight years before the impact.
18:29How many more eggs?
18:31More possibilities for survival.
18:43Eggs were easy targets for predators
18:46during the long weeks they stayed in the nest.
18:58But how did they survive?
19:18The nests had to be built
19:20with the materials available.
19:22The forests were plagued with dangers,
19:25like the creatures that would not dare
19:27attack an adult rex,
19:29but who did not have the same reserves
19:31as their young.
19:53The eggs are porous,
19:55which allows the embryo
19:57to breathe through the shell.
19:59If it is submerged in water,
20:01the embryo will die drowned.
20:23The eggs are not only a source of food,
20:26but also a source of life.
20:29The nests were not only a source of food,
20:32but also a source of life.

23:58A new life begins.

24:15This one shared the planet with creatures that did not possess any of those qualities.
24:22Although the sight of the old Ankylosaurus is weak,
24:25its sense of smell is highly developed.

28:57The asteroid of 10 kilometers wide hit the north coast of the Yucatan Peninsula at a speed of 20 kilometers per second,
29:05and left a hole in the earth about 140 kilometers wide and 30 kilometers deep.
29:13and left a hole in the earth about 140 kilometers wide and 30 kilometers deep.
29:19The explosive power was equivalent to a billion Hiroshima bombs.
29:25The impact created megatsunamis, with waves that reached hundreds of meters,
29:31while the hot rubble started fires throughout the northern hemisphere.
29:37The impact caused massive earthquakes and volcanic eruptions.
29:43Certainly, anything in the asteroid's path would have been incinerated.
29:49It would have been terrible to be in Zone Zero when that rock fell from the sky.
29:53For animals and plants that were not in the area of the impact,
29:57it would have been a slow and painful death.
30:01The impact would have raised a large amount of ash that would gradually surround the globe.
30:07In a short time, most of the earth would be enveloped in a cloud of dust.
30:13The effect of the impact of that asteroid is the closest the world has been,
30:17and I hope the closest it will ever be, to a nuclear winter,
30:21what scientists predict would be the result of a thermonuclear world war.
30:31NARRATOR
30:3765 million years ago, the earth was enveloped in ash and darkness.
30:43This darkness devastates the cycle of life on the planet,
30:47as the vegetation dies due to the absence of light.
30:51All dinosaurs feed on sunlight.
30:55That sounds strange.
30:57But after all, plants feed on sunlight.
31:01Herbivores feed on plants.
31:03And carnivores feed on herbivores.
31:05If we eliminate sunlight, and you put the planet in the darkness,
31:09and the longer and more transient the darkness goes,
31:13the greater will be the extinction.
31:16The interesting thing about extinctions is that it is the best adapted animals that die first.
31:21If there is a specific animal class, or a plant that you have to eat,
31:25or a specific part of the ecosystem that you have to be in,
31:29and they disappear, you'll be the first to follow that road.
31:33It happened overnight, or in a period of days or weeks,
31:36or it lasted years or thousands of millions of years.
31:39I find it difficult to believe that all the dinosaurs, except the birds,
31:43would have disappeared during that event.
31:45A particular creature could have been one of the last survivors.
31:49So, if we think about the dinosaurs, not to mention the birds,
31:53that were around at the end of the Mesozoic,
31:56who would be most likely to survive longer in the Great Extinction?
32:01I think probably the Troodon.
32:03The Troodon is a very interesting animal.
32:06There are remains from Alaska down to the south of the United States.
32:10It is a strange animal, because its teeth don't tell us if it was totally carnivorous,
32:15and many paleontologists now argue that it probably ate both.
32:19The Troodon has a number of anatomical adaptations
32:23that suggest it could have been adapted to survive after the impact of the asteroid.
32:28First of all, it has big eyes, so it could see in the dark.
32:32Secondly, its teeth suggest that the diet was varied.
32:35And thirdly, it has feathers, so it would be isolated from the cold of the nuclear winter.
32:42One of the great advantages of being warm-blooded
32:44is that you can be active 24 hours a day.
32:47You don't need the sun to get going in the morning.
32:51And if the Troodon was nocturnal,
32:53it's maybe one of the indicators that this animal
32:56possessed elevated metabolic rates,
32:59and that it was almost, if not already, warm-blooded or endothermic.
33:04Of the dinosaurs that were around at the end of the Cretaceous,
33:08I think the Troodon and its close relatives
33:11were the ones that had the highest chance of surviving.

35:24There is evidence that, like penguins and ostriches,
35:28male trodons also participated in the breeding.
35:35It is even possible that they laid the eggs.
35:39But first, there had to be eggs.
35:43These couples are united by life.
35:46Life that is consumed quickly.
35:58The most important thing is to keep the eggs.
36:02And that's what we do.
36:05We don't just keep the eggs.
36:08We keep the life.
36:11We keep the life.
36:14We keep the life.

39:00The Troodon was one of the first to be able to accurately measure the size of the brain,
39:06one of the only raptor dinosaurs.
39:10The ratio between the brain and the size of the body is high in the Troodon,
39:14one of the highest ratios among dinosaurs.
39:16Now in the modern world, intelligence is usually associated with the size of the brain in relation to the body,
39:22so if that was applicable to the era of the dinosaurs,
39:25it's likely that the Troodon was one of the smartest we've ever discovered.
39:30By stealing eggs,
39:33taking care of the young,
39:36and hunting,
39:38the Troodon may have shown its intelligence in many ways.
39:43And yet, with all snow for it, the Troodon did not make it.
39:48I personally think it's possible that it was the one that survived the longest,
39:51apart from the birds,
39:53but sadly, the Troodon no longer exists.
40:01The day is over for the dinosaurs,
40:04but there are still a few hours of night ahead.
40:11The ancient rulers of the planet are now frozen corpses.

43:07We've seen many things in the dinosaur revolution.
43:12One of the biggest discoveries is that these dinosaurs survived
43:16one of the worst accidents in the world,
43:19and these were the birds.
43:21And so, in that sense, the dinosaurs are not extinct.
43:25We eat them as a show of gratitude.
43:27And so, they're still around us.
43:30By any measure, the history of the dinosaurs is a success story.
43:36We think that because we're here right now, that we're the best.
43:40But that's criticizing our great-grandparents,
43:43because they're not here anymore, and you are.
43:47Everything dies over time.
43:51Do you understand?
43:54Eventually, yeah.
