arundhati roy, thank you so much. thank you.ones thereof. it is actually about 70% complete, a total of nine metres long. and to make it more interesting, it is a newly discovered species of carnivorous dinosaur, discovered on private ground in the us. the french buyer paid more than $2 million. now here's the question — do we like this free trade in dinosaur bones? it's a nice windfall obviously for the person who owns the land on which the relic was found, but it couldn't be said to be their own creation. and scientists worry that if dinosaurs become another form of ostentatious consumption for the very rich — like art — then museums which study dinosaurs will never be able to compete. it is a question of the private versus public interest. i'm joined by emily rayfield, professor of palaeobiology at the university of bristol. very good evening to you. you're the vice president of the society of vertebrate palaeontology. take us through the argument? as you said the auction to the auction house and asked them to reconsider sell
