Dinosaurs - Diplodocus

Diplodocus was a large herbivorous dinosaur with a weight of approximately twenty metric tonnes and a length of about twenty-six metres. Fossil evidence found in the USA indicates that Diplodicus lived between 145 and 155 million years ago in the Late Jurassic period, walked on four legs, and used its long neck to reach high vegetation which it stripped with rows of comb-like teeth.
