It is interesting to imagine how the dinosaurs interacted with each other. In the painting below the carnivorous Ceratosaurus snarls at the larger plant eating Brachiosaurus frightening a small flock of flying reptiles called Rham-phorhynchus. This is a contest of giants. Although the Ceratosaurus is large, with a mass as great as one of today’s elephants, the Brachiosaurus is even larger at about 80 tonnes, twenty times more massive than a large elephant.
