A giant of the time was the herbivore dinosaur Brachiosaurus with the gigantic proportions: as high as a four-story house and as heavy as ten elephants. He moved at a speed of 5 - 17 km / h At 15.50 meters long and 13.27 meters high, this specimen is the largest constructed dinosaur skeleton in the world. The animal weighed about 50 tons before his death. The front legs were longer than the hind legs. So the animals with their long necks could reach the branches high up in the treetops. The head of the animal is very small in relation to the body, he could not chew his food with his spatulated teeth, instead he bit off branches and swallowed them uncorrupted. He was probably fed on conifers.
