Attenborough and the Giant Dinosaur (1x31)

:

Filmed over two years, Sir David Attenborough will tell the story of the fossil discovery and reconstruction in Argentina of the largest known dinosaur, a new species of titanosaur. Measuring 37m long - close to four London buses put end to end - and weighing 70 metric tons, latest calculations show that this new giant titanosaur is the biggest animal ever to walk the earth.
