Size comparison between the Brachiosaurus dinosaur and the human.

The name of this dinosaur comes from the Greek language and means: lizard arm, in reference to its long arms. It is one of the largest dinosaurs to have roamed the surface of the Earth. Paleantologists believe that brachiosaurs could eat up to 400 kg of plants per day. Among the plants that we find at this time, there are bennettitales, conifers, equisetum, ferns, ginkgos, petridospermatophytes, cycads.
