The business of bones has been booming since 1997 when Chicago's field museum spent $7.6m on a Tyrannosaurus Rex named Sue. Since then, dinosaurs have become largely coveted darlings of the rich, which has spurred a growing number of fossil or dinosaur hunters. Does anyone have the right to privately own a dinosaur?

The stakes are high, the prices are even higher, so TechKnow decided to travel to London, Los Angeles and Copenhagen to meet auctioneers, museum curators and other scientists to talk about the business of bones and its implications on research and study. - Subscribe to our channel: http://aje.io/AJSubscribe - Follow us on Twitter: https://twitter.com/AJEnglish - Find us on Facebook: https://www.facebook.com/aljazeera - Check our website: http://www.aljazeera.com/
