En el fascinante mundo de los dinosaurios, la supervivencia no era solo una cuestión de fuerza; requería adaptaciones revolucionarias y estrategias de caza eficientes. Este episodio explora cómo los Utahraptores, parientes de los velocirraptores del "Parque Jurásico", empleaban tácticas de caza en grupo para derribar presas más grandes. A lo largo de la era de los dinosaurios, diversas especies desarrollaron habilidades únicas para adaptarse a su entorno, desde cambios físicos hasta comportamientos sociales complejos.
Los Utahraptores, conocidos por su impresionante agilidad y velocidad, cazaban en manadas, lo que les otorgaba una ventaja significativa sobre sus presas. Al trabajar en equipo, estos depredadores podían coordinar sus ataques y aumentar sus posibilidades de éxito. Este episodio no solo revela los secretos de la caza de los Utahraptores, sino que también destaca cómo la evolución moldeó a estas criaturas para enfrentarse a los desafíos de su tiempo.
Sumérgete en el mundo prehistórico y descubre cómo las adaptaciones de los dinosaurios les permitieron prosperar en un ambiente tan hostil. Aprende sobre la interrelación entre las especies y cómo cada una encontró su lugar en el ecosistema. No te pierdas este viaje educativo que desvela los misterios de la vida y la supervivencia de los dinosaurios.

00:30It's been a long time since dinosaurs have captivated our imagination.
00:37But much of what we knew about them was wrong.
00:41Now, a scientific revolution has transformed its history.
00:49Forcing us to analyze dinosaurs in new and revolutionary ways.
00:57If we compare how science has been applied to study dinosaurs
01:00for almost the whole 20th century,
01:02in contrast to the last 40 years, it is radically different.
01:06And during the reinvention process, dinosaurs have been recharged.
01:11For at least 150 or 160 million years,
01:14dinosaurs were one of the dominant living species.
01:20There were immense predators in the air.
01:25There were massive predators on land.
01:29There were animals that could eat anything with horns, tails, or claws.
01:35So, one of the key questions about them is,
01:39why did they do so well?
01:41It is possible that they survived thanks to group hunting,
01:45to develop their own body armor,
01:49or to see the world in a way that we had never imagined.
01:57Welcome to the kingdom of dinosaurs.

02:24125 MILLION YEARS AGO
02:30125 million years ago, in the lower Cretaceous,
02:35large sauropods such as the Cedarosaurus
02:38migrated across the territory in search of food and water.

02:55Like many giant herbivores, the Cedarosaurus traveled in flocks,
03:00where the gigantic adults could protect the younger ones.
03:07But on this route there are bandits,
03:13like the Yutarraptor,
03:25a lethal predator.
03:56It is possible that what they lacked in size
03:59they compensated with meticulously coordinated attacks.

07:06YUTARRAPTOR
07:09The Yutarraptors were the ultimate killing machine.
07:14We can say without fear of being wrong that a single Yutarraptor was as dangerous an opponent as a grizzly bear today.
07:21Unlike the grizzly, it was probably a very fast animal.
07:26Likewise, there is evidence that even the great raptors could have lived in herds.
07:33And so it's quite likely that the Utahraptor
07:36would have operated in a group
07:38if they intended a larger prey than themselves.
07:41And this group carried very dangerous weapons.
07:45We're talking about a curved blade this long.
07:48Whether it was used to stab, or to slash,
07:51or just to tear the entrails while they held the prey,
07:54it had to be a formidable weapon
07:56that they could have used against larger prey.
07:59DINOSAURS
08:04DINOSAURS
08:09DINOSAURS
08:11Dinosaurs were the ultimate survivors
08:14because they're still with us today.
08:17One of the biggest revolutions in the last 15 years
08:21has been the discovery that birds descend from dinosaurs.
08:26However, even if it's possible that it had feathers,
08:29this little one wasn't a bird.
08:31It was a 30-centimeter-tall raptor called Raonavis.
08:36It was probably fast,
08:38it certainly had wings,
08:40it probably had the ability to plan,
08:43and maybe it was even capable of flying,
08:45waving its wings.
08:48And so, step by step,
08:50the adaptations,
08:52the techniques,
08:54the anatomical changes that helped this little dinosaur
08:57to survive at each moment,
09:00would end up leading to these wonderful creatures,
09:03the birds.

15:11We talk about the Mesozoic as the era of the dinosaurs.
15:16But it was more than that.
15:18Because there were other groups that also prospered.
15:21The dinosaur revolution has also brought to light
15:24a whole range of secondary characters, unbelievable.
15:28The Beelzebub was a giant frog discovered
15:31by our group on the island of Madagascar.
15:34For years we found fragments and finally we gathered enough
15:38to reconstruct most of an animal
15:41that turned out to be the largest known frog.
15:44The closest relative is in South America
15:47and it is the so-called Pacman frog,
15:50which eats almost anything that fits in its mouth.
15:53A Beelzebub frog could be the size of a small dinosaur.
15:57Could it eat dinosaurs?
15:59Perhaps.
16:00Small dinosaurs, just out of the shell.
16:03The Beelzebub was within that range.
16:06If it weighed about four kilos, it could eat a dinosaur.
16:09It's strange to imagine a frog eating a dinosaur,
16:13but the Beelzebub was in the size that would make this behavior feasible.
16:18It was like this, more or less, this big.
16:21It was not a frog that you would want to bother.
16:24One thing that the dinosaur revolution has taught us
16:27is that these were not at all simple and stupid animals.
16:30There is a quote by Albert Einstein that says,
16:33everything must be done as simple as possible, but no more.
16:37And in my opinion, we have spent decades simplifying the dinosaurs,
16:41but we have not been able to simplify them.
16:44We have not been able to simplify them,
16:47but we have not been able to simplify them.
16:50And in my opinion, we have spent decades simplifying the dinosaurs,
16:54and now we know that they were more complex.
16:57It is possible that dinosaurs have learned from the environment and from their species.
17:02We often associate the size of the brain with intelligence.
17:06The brains are overrated.
17:08It is not necessary to have a large brain to have a complex behavior.
17:12It is possible that they have also seen the world in a more vivid way
17:15than we thought at first.
17:18It is almost certain that dinosaurs had eyes similar to birds,
17:22and that they could appreciate the intensity of color
17:25more than mammals like us can.
17:28If they could observe the world and learn,
17:31they would have more possibilities of surviving,
17:34since danger could present itself in different shapes, colors and sizes.
17:39160 million years ago, in China,
17:42the long-necked herbivores saw the beginning of their golden age.
17:46And here is the Sunosaurus.

23:47The Jurassic was the golden age of giant dinosaurs,
23:49The Jurassic was the golden age of giant dinosaurs,
23:54they really dominated the Earth.
23:57but they really dominated the Earth.
24:00But the finding of new fossils shows that mammals had adapted to survive in their world playing many more complex and different roles earlier than we imagined.
24:08playing many more complex and different roles earlier than we imagined.
24:12For example, there were Jurassic beavers.
24:16This is an animal of which there was no indication a few years ago.
24:20It had not found anything like the time of the dinosaurs.
24:23And believe it or not, there were even Jurassic flying squirrels.
24:28So these two new findings are very representative of a whole new era
24:33in the understanding of the animals of the Mesozoic.
24:37China during the Upper Jurassic.
24:40A land of forests, rivers and crowned dragons called Guanglong.
24:50It is difficult to believe that these two are related to the imposing T-Rex.

28:57Esta todavía es la época dorada de los dinosaurios
29:02y
29:33Ah algún día los mamíferos dominarán la tierra
29:45En este caso con un poco de ayuda de sus vecinos los reptiles
30:02Y
30:06Uno de los dinosaurios más comunes y permanentes fue el protoceratops
30:12una criatura equipada con algunas herramientas muy efectivas para la supervivencia
30:17A simple vista dado que no tiene cuernos da la impresión de ser un animal debilucho
30:22pero al final del cráneo tenía un pico
30:24Aunque es posible que lo usara para arrancar plantas para comer sin duda también lo usaría contra un depredador si fuese necesario
30:32pero un pico muy afilado
30:34Pero como en todos los animales una cría de protoceratops era vulnerable
30:40Una cría de protoceratops que se haya quedado sola
30:44Probablemente no viva mucho tiempo así que intentará encontrar
30:49Aparentes con los que poder sobrevivir
30:51Es posible que se una a un ejemplar o incluso mejor a una manada
30:57Pero una manada puede ser difícil de encontrar sobre todo si te acabas de quedar huérfano
31:09Hace 75 millones de años desierto de gobi
31:18Y
31:22El protoceratops a menudo viajaba en manada
31:27Así que es extraño encontrar a un espécimen adulto y solitario en las llanuras de mongolia durante el cretácico
31:48Oh
32:18Oh
32:48Hmm
33:18Oh
33:48Hmm
34:18Hmm
34:48Hmm
35:18Hmm
35:48Hmm
36:18Hmm
36:48Oh
37:18Oh
37:29With dinosaur in a studio de los dinosaurios casi nunca tenemos una instantánea de su comportamiento
37:35Pero en el caso de los llamados dinosaurios luchadores un protoceratops y un velociraptor
37:42Fosilizados juntos es muy posible que tengamos precisamente esa instantánea
37:47Es un velociraptor
37:50Atrapado en lo que parece ser un abrazo mortal con un protoceratops
37:54la mano derecha del velociraptor
37:57está atrapada en el pico del protoceratops y la izquierda está junto al cráneo o
38:02posiblemente en la zona del cuello del protoceratops
38:06parece que ambos
38:08Murieron durante el desprendimiento de una duna de arena
38:13Mientras estaban inmersos en una lucha a muerte
38:16Esto es excepcional porque no solemos encontrar muestras de comportamiento
38:21Fosilizadas con mucha frecuencia
38:23Imagínense lo asombroso que es tener este preciso momento capturado en un fósil
38:29Brasil hace 125 millones de años
38:39Mientras los dinosaurios dominaban la tierra otro grupo de animales dominaba el cielo
38:45Los reptiles voladores conocidos como pterosaurios
40:45Oh
41:15Oh
41:45Oh
42:15Oh
42:45Oh
42:47Oh
43:12Los dinosaurios no dominaron la tierra durante
43:15135 millones de años por casualidad
43:20Como sobrevivir en un mundo como el mundo del mesozoico quizá trabajando en equipo para derribar a una gran presa
43:29quizá encontrando el modo de batir las alas para subir a un árbol y esconderse de un depredador
43:35quizá volando mejor que ningún otro
43:39fuera cual fuera la estrategia empleada
43:42Los diferentes dinosaurios mamíferos y pterosaurios
43:45encontraron el modo de sobrevivir y transmitir sus genes a lo largo de la era de los dinosaurios
43:53Y esa era de los dinosaurios nos ha proporcionado muchas historias que contar
43:58la revolución de los dinosaurios no ha hecho más que comenzar
