Brachiosaure

Brachiosaurus ( lizard with arm ) was gigantic a Dinosaure Herbivore, one of largest which existed ever, and probably heaviest.

This Sauropode quadruped lived between the end of the Jurassic and the medium of the Crétacé, between 153 and 113 million years before our era. Of a 25 m length, its weight could reach 30 to 50 tons (ten of our current elephants). The length of its neck (12 vertebrae of 70 cm), raises questions which divided the paleontologists. Some think that it was not sufficiently muscular to draw up it with the manner of a giraffe. It is certain that blood was to have an important pressure so that it can reach its brain perched high. The morphology of brachiosaurus enabled him to balance its neck, from right to left, upwards, until the height of a building of four floors. It thus could brouter the ferns as much as reaching the summit of the trees to nourish itself (Conifère S and Cycas). Digestion was carried out in a gizzard and a cæcum. It is thought that it moved in small herds, the youngest adults protecting from large predatory the Théropode S.

One found specimens of brachiosaurus in North America, in the states of the Colorado, the Wyoming and the Utah, like in Tanzania, Algérie and Portugal.
