 New species of plant-eating dinosaur has been discovered in Britain. CBS's Vicki Barker from London. It's the most complete dinosaur discovered in the UK in 100 years. It's called Compton Nautus, and that name means Compton Thunderer, because it would have been really quite a large animal. Susan Maidment of London's Natural History Museum says this lumbering herbivore would have been about the size and weight of a large elephant. It was a dinosaur that probably moved on both two legs and four legs. This is CBS News.
