Pupils from CCC Kwei Wah Shan College, North Point, are dwarfed by the reconstruction of a prehistoric woolly mammoth. The animatronic model, standing alongside a skeleton of the species - mammuthus primigenius - is part of the Mega Exhibition of China's Ancient Mammal Fossils at Olympian City. The show, which took property developers Sino Group a year to plan, displays 10 prehistoric skeletons on loan from Beijing Museum of Natural History, the first time they have been seen outside the mainland. The 200 Kwai Wah Shan pupils were just one of many school groups given tours with a commentary this week, and filled in work sheets as they went round, teacher Lee Kwok-chuen said. The exhibition, which is in the Olympic mall's central atrium, features the museum's latest discovery, a giraffe-like shansitherium fuguensis, one of only three in the world, all in Beijing. Other fossils include a giant rhinoceros, discovered in the Hanjiang area of Shaanxi province, and a giant straight-tusked elephant, closely related to the modern Asian variety. The exhibition, which opened last weekend, runs until October 17.
