Found the skull of a comprehensive Pliosaurus
The predator was the fiercest Jurassic Pliosauro prehistoric oceans: of the fossil skull of this reptile, which alone reaches 3 meters long, will now be exposed and studied at the Dorset County Museum, English village where he was found in 2009.
If the discovery of the fossil dates back almost two years ago, only recently have paleontologists have been able to unearth and reconstruct the entire skull of this huge reptile, whose sharp teeth and powerful jaws of the law give the title of the most ferocious predator that ever existed on Earth until now, so much so that scientists believe the creature could represent a new species or even a new animal kind.
"We have seen this fossil as a pile of bones at the beginning, Slowly and with much hard work, was released completely from the rock. The skull has now identified the complete 95 percent and is probably one of the largest and certainly one of the best preserved and complete pliosauri now found all over the world ", said Richard Edmonds, natural scientist of the Dorset County Counsil.
Triceratops
POWER: Herbivore
Length: 9 Height m: 2,5 m
weight: 5-6 t
The Triceratops lived about 70 million years ago, in the late Cretaceous, North America. It was a dinosaur by body mass and muscular, similar in appearance to that of current rhino. Quadruped, with a short coda piuttosto, had significantly longer hind legs than front feet wide and offering a safe place in this animal heavy and slow. Remarkable was the chief: over long 2 m, almost one third of the total length of the animal, had a collar bone ornamented with tubercles and spines, as a shield that covered the back of the head, the neck and shoulders. The three horns protruding snout armored, a short, stubby nose and two very long above each eye. These horns are an excellent way of defense against carnivorous dinosaurs, but served just as well as offensive weapon in fights between males for the conquest of females.

Brachiosaurus: The lizard with his arms
Brachiosaurus
(“Lizard with arms”)
POWER: Herbivore
Length: 23 m
Height: 12 m
weight: 80 t
Il Brachiosaurus, who lived in the Upper Jurassic, about 150 million years ago, was a huge dinosaur sized. Suffice it to say that her body mass measured 6 m behind, and with the long neck could lift the little head about 12 meters above the ground. Including the tail reached the 23 meters long, weighing more than 80 t.
At one time scholars believed that the Brachiosaurus lived in the lakes and rivers, where the water could help to support the weight. The hypothesis was confirmed by the positions of large nostrils at the top of the skull, that would allow him to remain under water, emerge, leaving only the head to breathe.

Velociraptor
POWER: carnivorous
Length: 2 m
weight: 50 kg
It Velociraptor, lived in the Cretaceous, 90 million years ago, was probably the most terrible and bloody predator ever appeared on Earth.
It was an animal of small-vessel, just two meters long, for a weight of about 50 chili. In the skull, equipped with powerful jaw muscles, opened his mouth armed with more than 70 teeth strong and hooked, with which tore and shredded the flesh of his victims. The orbits were large and had also developed the space for the brain, which suggests an intelligent predator, sharp-sighted, sensitive to many stimuli and capable of lightning reactions.
neck, slender, curved, should be quite mobile, while the backbone was rigid and robust, and allowed the animal to run on its hind legs with the body parallel to the ground. The front limbs ended with three clawed fingers, but they were mainly used to hold prey; the true lethal weapon was the big place on the second toe claw of each foot.

tyrannosaurus rex
POWER: carnivorous
Length: 12 Height m: 5 m
weight: 6 t
It Tyrannosaurus rex, The “king of the tyrant reptiles”, lived during the Late Cretaceous, about 70 million years ago. He was one of the largest and heaviest dinosaur carnivores: his body was up to 12 meters long, including the tail, His head could stand up to 5 meters above the ground, and its weight could possibly overcome the 6 t.
But what was impressive was his mouth, that opens into a skull over a meter long, and was provided with more than fifty long sharp teeth, sharp and curved backwards to hold the prey.
The mighty Tyrannosaurus proceeded erect on its hind legs, with the long tail that balances the weight of the body. He was able to run at high speed, but probably was too heavy to support long-running. Its hunting technique was thus dependent on ambushes and sudden ambushes.
Hidden deep in the forests of ferns, silent waiting for the prey to approach and then pounced on them. Keeping them with short front legs which have two thin fingers and clawed, shot by the terrible tusks, and with the large claws of the hind legs.
Among his victims included other dinosaurs, mostly bipedal herbivores; is probable that the occasion is not ashamed to also feed on carrion, considering the huge amount of food that allegedly served him every day.
