Brachiosaurus

The Brachiosaurus was one of the tallest animals that walked on earth. He lived in the late Jurassic (154-153 million years ago). It was discovered in 1903 by the paleontologist Elmer S. Riggs in Colorado River formation. The first fossil was a part of his skull, but other fossils were found very fast. When first discovered scientists named the animal Brachiosaurus which means arm lizard because his arms were longer than his legs. Brachiosaurus had only one specie Brachiosaurus altithorax. There were more species discovered but they all were the same and one was another animal. His nearest cousin is Giraffatitan was located in Africa. It belonged to the sauropodian clade known for their long necks and tails.

Brachiosaurus could reach 25 meters and weighted 58 metric tons. His head was very little compared to his huge body. We think it had a similar life like giraffas because his construction was similar too. He ate the leaves of the highest plants and trees that lived during his time. But his big body was very heavy and probably Brachiosaurus was very slow which made him an easy prey. This gigantic dinosaur was the prehistoric skyscraper.
