Nicolas Cage returned a rare dinosaur skull to Mongolia after learning it was illegally smuggled out of the country. Cage purchased the skull at a Beverly Hills auction in 2007, outbidding Leonardo DiCaprio with a winning price of $276,000. Apparently you're not an official mogul in Hollywood until you have that skull bling. It makes sense as a benchmark for success, since so many people are obsessed with dinosaurs when they're kids.

The skull was from a Tyrannosaurus bataar skeleton, fossils of which have only ever been discovered in Mongolia. The paleontologist responsible for smuggling the skeleton from Mongolia was arrested in 2012, after which he helped authorities track down several fossils he had sold illegally.
