In a world first, the Australian Museum presents "Tyrannosaurs: Meet the Family", an innovative, multimedia experience showcasing the newly-revised tyrannosaur family tree. With over 10 life-sized dinosaur specimens on display, including one of the oldest tyrannosaurs, Guanlong wucaii, the exhibition runs from 23 November 2013 to 27 July 2014. Showcasing a dramatic array of fossils and casts of tyrannosaur specimens, including neverbefore-seen specimens from China, "Tyrannosaurs: Meet the Family" is designed to provide a snapshot of dinosaur life and show how this group became the world's top predators with their massive skulls, powerful jaws and bone-crunching teeth.
