A Tyrannosaurus rex skeleton, made up of bones from three different T-rexes, has sold at auction for 5.5 million Swiss francs (that’s $9 million Australian or $US6.1 million).

Estimated to be 65 to 67 million years old, the skeleton was sold at the Koller auction house in Zurich, Switzerland, on April 18 after being shipped from the US in nine giant crates.

The skeleton, called Trinity, was put up for sale by an anonymous* American and was bought by a private European collector of modern art and dinosaur relics.
