The Sauroposeidon who lived during the Cretaceous, in what is now North America, is the largest known lizard, long and weighing of all land animals throughout the history of the Earth. Hence its name, which means "lizard god of earthquakes."
This vegetarian sauropod is ahead in size and weight above Argentinosaurus, Ultrasauros and other sauropods.
Well, the Sauroposeidon reached 17 meters in height (as a 6-storey building) and weigh up to 60 tons (more than 10 African savannah elephants together) and a length of 35 meters (100 ft).
To give an idea of what was long enough to know that one of his vertebrae could be up to 1.20 meters long (4 ft). And only the neck measuring up to 12 meters (37–39 ft).
This is why it is ranked as the longest dinosaur history.
These amazing animals are among the heaviest dinosaur that ever lived. Although his body resembled that of other sauropods, surpassed in size to most of its peers. It was about 25 times heavier than a giraffe long as three buses and as tall as a six-story building. Its neck and tail, incredibly long, were supported by a backbone like a grill. At the sides of the vertebrae, there were some openings that reduce weight without weakening his back. Most of the weight of its giant dinosaur bore members. Therefore, major bones were the blades, connecting the front legs with the body. The was large and strong, each of them would be higher than a soccer goal. His back was lower than their shoulders, as the hind legs were shorter than the front. When grazing among the plants and bushes, swinging his long neck in all directions. It could reach the juicy leaves of higher tops and low ferns. I needed lots of vegetation, cutting his teeth beveled. For easier digestion, probably swallowed small rocks that were deposited in your belly and helped to turn plants into pulp. Although hard to imagine, experts have suggested that brachiosaurids like this, roamed in herds slowly advancing. Surely the ground shake under their feet. The sheer size of an animal as this dinosaur probably deterred most predators living at the time. But if one is away from the bequest, was exposed to grave danger. On the inside of his legs, like those of elephants, had a sharp claw. With an accurate kick and a flick of its tail flexible, could bring down his enemy. Measuring up to 30 meters long and a little more than 15 high. It lived about 145 million years, at the end of the Jurassic period in North America.
Curious: There is another dinosaur called Ultrsaurus, but not the same, is smaller and fossils found in Asia.
