Last Thursday, the Hong Kong Science Museum unveiled the dinosaur it had been given as a gift from the mainland. Chief Executive Donald Tsang Yam-kuen was the guest-of-honour at the opening ceremony of the Treasure from Chuxiong - Lufengosaur exhibition. The fossilised bones of a lufengosaur were donated by the government of Yunnan province . This is the first time dinosaur remains have been given to an institution outside the mainland. The skeleton consists of more than 300 pieces of bone. It was unearthed in Lufeng , which is known as the 'Homeland of the Dinosaurs', in Yunnan province in June last year. Mr Tsang said: 'We are extremely grateful for Yunan province's kindness and the motherland's care about and support for Hong Kong. The fossil exhibition can certainly arouse the interest of Hong Kong citizens, especially young people, to study paleontology. I hope these young people will be able to make contributions to scientific research in China.' The skeleton is considered extremely rare as it is more than 70 per cent complete. Most of the parts in the exhibit are real fossils except for the head and parts of the tail bone, which are fake. Fossilised dinosaur heads are extremely hard to find and are seldom put on display. The original head was left in Yunnan. The entire dinosaur weighs up to 1,000 kilograms. Lufengosaur lived 180 million years ago in the Jurassic Period. It was one of the first species of dinosaurs to be found in China. The fossil will be displayed in the lobby of the Science Museum until April 29. Admission is free. It will then be moved to the Life Sciences Hall of the museum for permanent display. The museum will host a special lecture about dinosaurs on December 13.
