STYRACOSAURUS


Within the family of ceratopsidae (those horned animals that lived in the prehistory), we can find some animals we know. Since Torosaurus (large and with two horns) to the Eotriceratops, Triceratops (always represented fighting a T. Rex and three horns) and Pentaceratops (smaller than the other two but with 5 horns) ...

As you can see, in this short list you can see that the number of horns increases between 2 and 5. At the end of the list more would see the ceratopsian horns, Styracosaurus, the protagonist of this entry.

The name means lizard Styracosaurus horns.

It had a horn on the front of the head, one big and long, but most of the horns, to which its name refers, are those found in the "wheel" of the head, a bone coating that protects the neck. A hedge that protects the neck from predators carnivores such as T. Rex. But the horns of Styracosaurus, not small bony protuberances, horns are up to 60 cm long and 15 cm wide at the base. This contained the snacks in the neck and the same also used for exposing himself to females.

So, this herbivore than 3 tons and 6 meters long would be therefore difficult to kill prey. Fossils found dead near ceratopsidae Tiranosauros like Styracosaurus who have tried to hunt. Hunt In Styracosaurus, T. Rex could be gored to death.

The horns and shells daubed the neck, the most vulnerable part of the animal, predators could not bite the neck without risk a fatal goring. The predator hunting tactics would try to turn the Styracosaurus and put belly up, where the T.Rex would find the most soft, unprotected part and away from the huge antlers.

This large herbivorous mid Cretaceous lived in what is now North America. And from afar, remind us a huge rhino with large spiked collar and long tail. Indeed, like other ceratopsidae, had a mouth shaped peak finished ... psittacosaurus reminds me.


The Pentaceratops.



To end this year, 2012, best animal to learn that the prehistoric Pentaceratops. It could be any other, nothing would happen, but this is a little special. Basically, the reason that I consider this animal special, not because I have three horns and call Pentaceratops (5 horns), but because it is the largest land animal with the head of the whole story.

If someone calls you "big head" is because they do not know the Pentaceratops. An animal with a head of up to 3.5 meters (12 ft). A strong neck muscles full of robust bones embedded in supporting a large skull with a bone covered with thorns wheel and 2 meters (7 ft) in diameter. This collar bone was a formidable protector and a dominant male signal.

The Pentaceratops was taller and thinner the triceratops, less heavy, but a little higher. With strong legs, almost 6 tons, as a male African elephant, and 8 meters (26 ft) long. It, like other ceratopsians, was an herbivore and gregarious. With its enormous beak similar to a parrot, tore branches and bark to eat.

The Pentaceratops lived around the Campanian, Late Cretaceous 75 million years ago. Therefore triceratops existed before and not had to face with T.Rex. However, if you had the predator to Daspletosaurus or Acrocanthosaurus.

By the way, we see its curious name: your name means five horns and really have 3 is because it had two great apophysis (build bone) protruding from their cheeks. Views with meat, muscle and skin, these bumps closely resemble the bumps of the warthog.




Triceratops vs T-rex.

The legendary battle between Triceratops and T. Rex, maybe a little classic, this confrontation itself may have occurred in antiquity, in reality, and this gives a particularly morbid.


In old movies, in books for children and television shows have used this resource, this battle, as an incentive to attract attention, create suspense and tension. In some cases, the T. Rex killed the Triceratops and in other cases it was the other way around ... But in reality ... Who would win both?

This video is a movie made in 1925, was called Lost World. The Triceratops was heavy, slow and with horns that seem to exceed 50 cm. But it was not.

Triceratops.


Lengths up to 10 meters long (30 ft).
Weight: up to 12 tons (26.000 lb).
Horn of 1 meter length each. (3 ft)
Height: up to 3 meters. (9 ft)
Speed ​​of 35 km / h


T. REX.


Lengths up to 13 meters long. (40 ft)
Weight: 10 tons. (20.000 lb)
Height: 4 meters. (12 ft)
Mouth with a strong bite.
Speed ​​40 km / h.

NOW LET'S SEE YOUR SKELETONS:








There are many things to consider. The powerful bite of T. rex and its poisonous saliva, and its form of attack. The speed of Triceratops that if envistiera to 35 km / h, could go through with his horn the body of T. Rex. The robustness of the body and a collar bone that covered his neck and massive head 2 meters of the Triceratops.

Daspletosaurus


THE TERRIBLE carnivorous reptiles. That was the name we put this dinosaur, Daspletosaurus. It was another prehistoric animal Tyranosaurido fierce-looking and although a little smaller than its cousin the famous Tyranosaurio. Even being smaller, this dinosaur was a predator that stood at the top of the food chain and devouring other animals such as large or some Ceratopsidae hadrosaurids (horned Triceratops) of several tons.

Possibly, his name is due to the impression that was taxed in the retina of the paleontologists who discovered it: a huge head of 1 meter with 72 serrated teeth, long and sharp with heterodoncia (specialized teeth). Measuring up to 9 meters long and it is estimated that almost could have reached the 4,000 kg.

A feature to highlight in this prehistoric predator was his strong neck and a strong legs (compared with other similar sized tyranosauridos.

The strong hind legs brought him agility and speed in racing, and a starting power and strength to pursue valuable prey. It was really a terrible carnivore and fast.



On the strength of his neck, holding a skull strong armed indeed, its function was to hold its prey. Since its forelegs were minimal and not very useful, Daspletosaurus used their strong teeth to catch and mortally wound its prey. Grab their prey with a bite bowed numerous sharp teeth and retained and the onslaught endured and the struggles of its prey with its powerful neck.


The Daspletosaurus lived in North America in the Cretaceous period about 75 million years.

In the video below looks like a group of successful practice Daspletosaurus a hunt. (Up to 4.40 min)




Triceratops


Individual Triceratops are estimated to have reached about 7.9 to 9.0 m (26.0–29.5 ft) in length, 2.9 to 3.0 m (9.5–9.8 ft) in height, and 6.1–12.0 tonnes (13,000-26,000 lb) in weight. The most distinctive feature is their large skull, among the largest of all land animals. It could grow to be over 2 m (7 ft) in length, and could reach almost a third of the length of the entire animal. It bore a single horn on the snout, above the nostrils, and a pair of horns approximately 1 m (3 ft) long, with one above each eye. To the rear of the skull was a relatively short, bony frill. Most other ceratopsids had large fenestrae in their frills, while those of Triceratops were noticeably solid.

Triceratops species possessed a sturdy build, with strong limbs and short five-hoofed hands and four-hoofed feet. Although certainly quadrupedal, the posture of these dinosaurs has long been the subject of some debate. Originally, it was believed that the front legs of the animal had to be sprawling at angles from the thorax, in order to better bear the weight of the head.

Triceratops is a genus of herbivorous ceratopsid dinosaur which lived during the late Maastrichtian stage of the Late Cretaceous Period, around 68 to 65 million years ago (mya) in what is now North America.
