The largest living land animal is the African elephant, which reaches a weight of 7,500 kg and stands 3-4 m high at the shoulders when fully grown.
However, the African elephant is dwarfed by some extinct plant-eating dinosaurs, which may have weighed at least 80 tonnes, and reached a length of 30 m. It was thought that the weight of these huge creatures had to be supported by water. It is now known that they inhabited regions similar to those of elephants.
