THE MASSIVE CREATURE that can be seen spread across the next eight pages was one of the biggest dinosaurs ever to walk the Earth. It was called Diplodocus, and like Mamenchisaurus, opposite, it belonged to a group of dinosaurs called sauropods(p. 12) Diplodocus looked extraordinary with its long neck and tail,and a head that was tiny in proportion to the rest of its body. This type of body su its lifestyle perfectly. It could reach up to feed at the tc the very tall trees, like conifers, that grew at the time. small head allowed it to browse amongst the vegetation where few other dinosaurs could reach. This type of feeding needed a special type of neck- one that was strong light, and flexible, in order to be raised and lowered easily. Having stripper one area bare of food, it would have ambled off with its companions in search of new feeding grounds. If Diplodocus was threatened by a meat eater, its only defence would have been its bulk, and its long, whip-like tail(pp. 20-21)
