Plot Summary

David Attenborough travel to arid Patagonia in southern Argentina, where accidental fossil finds allowed after intensive digs, including a nest site, to reconstruct in a specially adapted industrial workhouse the largest-ever dinosaur and land animal, the vegetarian titanosaurus. Modern techniques allow an interdisciplinary team to extrapolate and compare with living animals. Its record (probably not surpassable) size and shape with elongated neck and balancing tail required extreme anatomical adaptations, even by giraffe and elephant standards.
